This is a neat idea and a VERY strong engine we made. We have a few of these floating around, and we are having 5 more sets of pistons made... :p

Components:
legacy 2.2 turbo block (NEW)
USDM 2.5 STi crank
Pauter Forged Rods
CP Custom Forged Pistons
ARP Head Studs

Final Displacement: 2.35 Liters

I'd rather go with that than the 2.5 STI block.

San

i've no idea whats being talked about
maybe one day i will understand all that jazzz

Yummy:)

Looks great! Was there any fabrication done to the crank or block to fit the 2.5 crank? How much boost can that monster take?

Here is a few answers from Mike at the other forums:

Cert Compression on the motor pictured is 9:1. However, normally they are 8.5:1. Displacement is 2.35 liters. It is a 2.0 liter rod and a 2.5 liter stroke.

west The rev limit is mainly determined by the cylinder head valvetrain. However, we have had these motors to 9500 RPMS just fine.

stickman Yes, you can run AVCS heads on this block (if they are wired up ). Price for the base block is $3500. Tapping for larger head studs is $250 + $250 for the ARP head studs. This motor will handle 500+ hp on race fuel. We saw ~360 whp on pump gas and 412whp on 95 octane (modded wrx).

Porkchop-WRX Price answered above, and these will bolt right up to WRX or JDM STi heads.

dwx You are correct sir. However, if the demand is there... We could certainly have new pistons made to accommodate the 9:1 request

What else is on the car that made that power? What turbo? What management?

Same motor I got. Sweet stuff.

If so nice numbers. Like BANSUVS said, details?
San

your engine is a FREAK! haha one great lookin freak though:banana:

BAN SUVS Our basic upgrade package, ported heads, jun 272 cams.. Our Fuel system. tec3.

It had another 40HP in it im pretty sure, but the engine was newer and the fuel we had problems dialing out after 6000 RPMS.

Turbo was a t3/t4 hybrid.

Imprezer This motor is a step below the one in your car, you can make A LOT more power.

oldmansan I think I answered him, and yes this is ~360 WHEEL hp on a dyno dynamics dyno. Winter pump 93, similar to 'good' 91 octane.

-Mike
www.axispowerracing.net

Hey Mike! ;)

Really? Cool. Haha. Makes me feel even better. I am about done with fixing all the stuff. I am waitng for breather hoses then Dyno time.

With new 3" downpipe and new uppipe and NO AVCS, I should make the power I am craving. ;)

---

Why is the power falling off though? Ron said it was pulling all the way to the 9000.

It wasnt nearly tuned to the max. On the street however, the 2.4 liter stroker did not want to stop pulling even @9500 rpms.
:D :cool:

notice the AFRs... After 6000 the tec3 decided it didnt want to let us control the fuel. We got that worked out but decided that this is a nice safe map for the gas we were running. However, if we could have dialed out after 6000 RPMs, things could be better... Notice where peak HP is. And a nice shelf of torque shown above.

Glad to see that people are finally realizing the creative and reliable potential of 2.2 blocks.

So far it seems this “new” block resembles what Crawford Performance has been doing, and we have been selling, for quite some time now.

On another note: Not to start a pissing match, but the information on the dyno sheet seems strange, especially the low torque values/numbers for such a 2.2 stroker kit. I actually have an old dyno plot in which you can see one of our 2.2 strokers , which is very similar to your axis power racing 2.2 stroker.
http://www.i-speed.us/images/dyno_comparison/dyno_charts_01.jpg


Here is that same dyno plot overlayed with your dyno dynamics plot:
http://www.i-speed.us/images/dyno_comparison/dyno_charts_02.jpg

Lastly, Torque and HP should cross at 5250rpms. Why do they intersect at 4500 on your dyno sheet?

Not only the graph information, But the area where "2.35l " on the first graph and then "2.35" on the second has obviosly been tampered with. The font is not even the same:(

We have been using 2.2 blocks for about 3 years. This is just a new cheap option that we offer that can handle a ton of power.

Here is the block that is in Alex’s car, omg is that a 2.2 liter? Don’t make it sound like we are copying you guys, that’s just idiocy.

The Bore is 3.815 on the 2.2 block.

Most "stroked" EJ motors are done the same way. Generally speaking. For example, use EJ22 block, EJ25 crank with custom pistons and rods. There isn't much to it. Saying that someone is copying someone in doing so, is like saying that everyone who brushes teeth with their right hand is copying me just because I do it the same way. ;)

However, the components and assembly techniques is what makes one stocked EJ motor different from another.

We were using a slightly larger turbo than normal on this motor. That and we are purposely keeping torque from coming in like a monster so the trans will stay together.

I think the cams are also playing a big factor with the outcome. Low boost, big lift and lots of duration takes away from the low and initial midrange. But look how the power builds nicely. It drops of because I was having problems with the TEC controlling the fuel above 6000rpms. On the street, it's a monster and revs up ever so nicely and smooth.

Ron

Very well put Alex.

There's only so many ways to build an EJ series engine. Unless you have big money.

You should look around on Pauter's site for their version of a ej motor. It's pretty crazy, but damn expensive.

I think the point some people are trying to make here are to allow the customer to be aware that data is to be questioned. If we don't question it, then what is the point of it? I have personally known quite a few people that have been cheated because of information they have seen. I am not saying Axis or I-Speed USA are incorrect but sometimes there are mistakes. So I have some questions I am not clear about.

1) Why do the torque and horsepower numbers cross at 4500? I thought they were suppose to cross at 5250, maybe I am missing something? An incorrect calibration on the dyno or maybe the computer overlayed the torque and horsepower incorrectly.

2) Do you think those A/F ratios are a little lean, especially on winter gas? I know a lot of poeple tell me they run 10.5:1 till about 6000 RPM's and then drop to 10:1. Just wondering if you think these are safe numbers?

Thanks for the information.
Bill Knose

I apoligize for having nothing to add to this post, but this looks like its going to be a very informitive thread.

Those numbers (AFR) look ok with regards to safety for 93 Octane to me especially on a built 2.xL motor.

Good point on the torque/HP numbers though! Mike/Ron any ideas on that?

Mike

Torque curve "supposed" to intersect hp curve at 5252, not 5250.

In this case, 4500PRM is the correct point for the curves to intersect. If someone proves me wrong, I will paint my car pinkish orangish polka dotted maroon. ;) It is trivial...

I am looking at the graphs and comparing them to others we have. Yes I see that most graphs do cross ~5200 RPMs. HOWEVER, if you check out the HP curve, it just made too much power too fast. Is that a bad thing? If they met at ~5200 that would require ~380 ft lbs of torque. This set up had another 30-40 HP in it easily... I wanted to see 400whp on pump gas. There was a fuel issue as Ron stated, and indicated by the AFR sheet.

and to answer question # 2. NO i dont think they are a little lean. Maybe the people who are running 10.5:1 and 10:1 are the reason for the 'low numbers' ;) I consider 10.6:1 almost pig rich, esp when you have a fully built motor and no hint of detonation.

-Mike

PS: keep the questions coming! :) Ron will log on and give his input tomorrow, this is just me talking.

EDIT: Its simple... The HP and Torque are scaled differently DURR :) its late

I ran my motor at 25psi for a bit. No detonation. That what will set one "stroked" EJ apart from another one. Some will explode at first signs of boost-related troubles, others will be happy at 25psi on 91 octane. 25psi on a t67, let me add. ;)

My numbers were a bit low, but thats due to AVCS-issue. That has been solved and the car will go back to the dyno shortly. ;)

Bill Knose
I-Speed USA

Hi guys,
I don't post much in this forum so forgive me if I'm coming in late. What Bill from I-speed is not realizing before crying foul is that the torque and hp axises are scaled differently for the purpose for screen fitment. If they were to share the same scale, the hp and torque curves would cross at 5250, as they rightfully should. Look at the respective hp and torque numbers at 5250 and, yes, they will be the same.

As for his comment regarding the results being lean, I am confused given the AFR graphs of all the I-Speed tuned cars we've tested/retuned.

As for hp, I think Ron's numbers are perfectly reasonable and downright impressive. The last EVO that dyno'd at 360whp on our Dyno Dynamics dyno put down 400whp at ATP a couple months back. And before that, the last 2.0 WRX we dyno'd at 290whp on our DD dyno put down 320whp at ATP during the ECU shootout dyno day we all participated in. Overlaying a DD graph over a Dynojet graph is like overlaying the picture of Pamela Anderson over Rin Tin Tin :)

My 2c,
Shiv

Thanks for clearing that up Shiv! I would still like to see the other graph you mentioned above for comparisions sakes of course :)

Please omit Rin Tin Tin though :)

...now overlaying Shiv's dyno graphs to Axis's will be like stacking Pam on Britney... Haha! I WANT TO SEE IT!

*nods*


so what are the differences between a closed deck 2.0l motor and a closed deck 2.2 (98 jdm model specficly)

98 JDM EJ20 motor is Phase I EJ.
US EJ22T is Phase I as well.

The only diff is the bore.

---

Pre-99, Subaru's WRC car was a Group N car. Hense, the need to have the same exact motor as a production car. For the type of abuse WRC cars see, closed deck is the only option.

In 99, Subaru went Open Class, and there was no need to have same exact motors in the production cars as in the WRC Open Class Impreza. So, we lost the fully closed deck blocks.

Sure, Phase II blocks have "other" advantages over Phase I. Like the crank bearing setup and few other ones. But, FULL CLOSED DECK will always be better than OPEN or SEMI-CLOSED.

*bows to the mighty subaru motor block masta*

Danka just wanted to make sure. *skips off into the distance with thoughts of his new phase one block being sleeved and bored*

Overbore a tad w/ darton's and you will have a motor that will rival most true race short blocks.

Pig rich, glad to hear it! I have heard many other reputable tuners say 11:1 being way to lean and will only destroy the car. Interesting to hear another opinion from another tuner.

Actually if you scale the HP and TQ graphs as Shiv stated then the paths cross as expected. Makes sense if you look at the HP scale on the left and Torque on the right and then match them the levels level off so to speak. I missed that on my first pass at the graphs!

Mike

I was being precise. 5252 is the correct #. But I guess I can live with 5250. ;)

When I said "supposed" to, it mean that it "would" intersect at that exact point IF the Horsepower and Toque axises were scaled the same. As you can see on the dynograph, the HP is scaled 0-450hp and TQ is scaled 0-550ft/lbs.

That is why the slope of the torque curve is higher than that of the horsepower curve. Hense an earlier intersect point.

Now, the reason they are scaled like that on Axis's dynograph, is precisely because of what Mike said. Sort of. ;)

Well i hate to point it out to you mike but you might have missed it due to the fact your eyes are accustomed to seeing thru fog that is as dense as steel. So next time just stare at it for a while until it comes into focus.

;)

1) Why do the torque and horsepower numbers cross at 4500? I thought they were suppose to cross at 5250, maybe I am missing something? An incorrect calibration on the dyno or maybe the computer overlayed the torque and horsepower incorrectly.

Wow, what a response to my question. If all our customers got responses like this we would have a lot of happy customers. Thank you all.

As an CAD GUI designer by profession it is very hard to make a clear and informative system for customers to use and understand easily. Dyno Dynamics has done a good job, as a suggestion could you set the curve intersection to 5252. Might make it easier to compare curves between dynos. That is all I was trying to get at. And Alex helped me clear up the incorrect value I used of 5250. You always learn something new.

As for his comment regarding the results being lean, I am confused given the AFR graphs of all the I-Speed tuned cars we've tested/retuned.

Thanks for the information. Glad to hear that other reputable companies are checking up on us.

Good morning, gentleman. We can take a look at why the torque and horsepower curves must meet at 5252 RPM:

HP = (torque * RPM) / 5252

horsepower equals torque multiplied by RPM, then divided by 5252.

Plugging in actual measured numbers for the variables will always result in curves that meet at 5252 RPM. It isn't an arbitrary number or a coincidence. The curves intersect at that figure because of the way horsepower is calculated.

nice motor, good price, nice numbers. You can post a picture of Mickey Mouse on the plot for all I care. I like your 2.4 motor, but the price on this one is hard to beat. Plus, for most of us, this motor will easily meet our power requirements.

San

Mike/Axis - Can you post all of the other bits and pieces that were on this car like a listed breakdown of the parts, I would think this may also help folks understand the power of this thing and how it was derived.

Mike

how about this everyone

im the fastest car ever cause shiv used his magical mojo powers to infuse my block with the power of 10,000 magical gnomes.

(stop *****ing at each other over stupid pride, sit down shut up and make something better if your soo damn butt hurt about it)

ANd that comment IS directed at EVERYONE in this thread who got butt hurt.

(side note: this thread can be either very prodductive or very childish lets keep it on the productive side of things people)

And axxis has a bad ass block and motor. As does ispeed, and we all know shiv is like gandlaf the grey with a dyno and laptop.

It had our basic upgrades.

Ported heads, valve train upgrade, jun cams, 2.35 LITER MOTOR, a ginormous t3/t4 hybrid, our custom fuel system, our custom intercooler/piping.

BUT, I will say this. That car is very customized and can make 550whp with the right tuning and gas. It did make 412 whp when we mixed a lil 100 octane to the mix. The 358 was at 19-20 psi and on pump gas (and on a dyno dynamics dyno, Shiv pointed out that would be 400whp on a dynojet Not too shabby for pump gas.

So to conclude. This block with other motor building mods will handle the power one would need w out purchasing our 2.4 stroker motor. I consider that more of a race motor.

I agree i am intrested in the oil and fuel system in particular.

Thanks for the response Mike.

Let's keep this one going....

Like Dre asked above I too am interested in the oil setup basically is there a different pump required when using a block with piston squirters?

Mike

that and did you use any sort of oil cooling

On the motor Axis built for me, I have Spec C oil pump. It supposed to flow more than usual. I have a pic somewhere showing the difference between the two. I am pretty sure you can use a normal pump as well.

Oil squirters do magic for oil temp and water temp. My motor is always very "cool". And, I don't even have a stock oil "puck" cooler.

I am getting a large GReddy oil cooler still though. ;)

the engine only needs ~30psi @ 2800 RPMS. We used an sti oil pump in this case. It made enough oil pressure to blow the seals on the first turbo LOL. So no, we didnt have any issues with oil pressure.

We had an oil cooler on there, but for the winter it is not hooked up... Things almost get 'too' cold when its 0-25 degrees outside heh

-Mike

i coudl see that as being a problem somewhere they had a bypass valve where only at a certain temp (225f<) it would let oil flow to the cooler. I know gary sheehan uses the remote oil adapter from the same company and they are based out of FL. (haha but i cant rem the damn name)

Is there any after market oilpumps aval for the ej series motors?

Cool thanks for the response.

How much boost with the right supporting mods do you think one of these blocks will handle?

Mike

Just thinking about it as i was entertaining the idea of a weldon fuel pump.

hey I-Speed check out the question on this link. think you can answer it? question click here (http://i-speed.why.do.all.your.motors.blow.up.youarelame.co m/)

you might need to hit refresh once or twice to get the full question ;)

30+/- psi, give or take... you can push anything... but how long will it last? :)

edit: we had a boost spike of ~57psi on a stroker motor and it held it fine... turbo blew, but the motor was fine lol.

This motor tuned properly can easily run 30 psi all day everyday

see above edit

Wow, that is some spike :eek:

I like the sound of this motor.

Mike

Um so do i jeebus!

"The Sound" is very unique indeed. You should hear it at 9,000RPM with a turbo pushing 23psi. ;) Sounds like a MIG. ;)

Me like!

Actually the boost spike was only 47psi, not 57. Car was quite quick for about 3-4 seconds, then boom. Turbo grenaded.

Engine didn't even whimper. It just took it all in stride.

I use sti oil pumps on all my complete engine builds. The manual states the engine only need 43psi @5000rpms, which isn't that much. I normally see something like 6 bar at operating temps which is 88psi. That's more than enough, even with piston squirters and all.

As for cooling issues, the closed deck doesn't effect cooling at all. Remeber, the head gasket has all those small holes in it, so it doesn't matter if the deck is open or closed. Water can only go through those holes anyway.


Finally, I would just like to say thanks to all those that support us and what we do. Those that know us, understand that we are only trying to support our racing habit by doing what we do and offering what we do.

Thanks guys,
Ron

Thanks Ron!

Nice site man, thank you :)

yes i made that whole site including the pictures and all the text and i also build all the motors.... and do all the reaserch... thanks for looking. Axispower racing just buys my motors from me and sells them as their own...... no wait..... they actually do their own reaserch and build/tune/everyting their own motors.... i must have been thinking of another vendor in this thread ;)

In this case, 4500PRM is the correct point for the curves to intersect. If someone proves me wrong, I will paint my car pinkish orangish polka dotted maroon. ;) It is trivial...

not sure if anyone got to this before, but I had to stop at this post and respond, sorry if it was answered...

the reason tq and hp cross at 5252 is because hp is a calculation that is derived from tq when multiplied (or is it devided?) by 5252. because of this, hp/tq will *always* intersect at 5252.

anyway, the reason those lines don't cross at 5252 is because the second line is not a value of tq, it looks like it is a/f ratio. or some other reading.

of course, I was looking at the second dino sheet, but the first one has two different scales.... that does it too :P

Chris, Its not really a good idea to overlay those plots from different dynos man. That Dyno D dyno that Ron has is a heart breaker of a dyno. 30-40whp different.

Quick question to the experts, is it true hte 04 usdm heads are shimless buckets?

yes. :)

have you guys worked your magic on a set of those yet? Are there any differences in the runners in the head vs an 02 or 03?

Or is it just the shimless buckets?

They sure look different from the outside.

Yes, there are differences on the inside as well.

I have not been able to get a good look at the internals of the us sti heads except for the cams. I guess I better order one up and check it out. I would suspect the ports are a compromise of wrx and spec c, meaning bigger than wrx but smaller than spec c. BUT I might be wrong on this having never actually looked at the ports on the us sti heads.

The us sti heads are setup to take avcs on the exhaust cams as well. Subaru is going to go to this setup very soon, maybe as early as next year. The castings are complete, they just need to work out the electronics.

Also, for those with 04 wrx's, you already have shimless buckets installed in your stock heads. Subaru did this in 03 everywhere else, and finally did it here as well this year. The buckets are fine for mild cam upgrades and higher rev limit, but can be expensive to replace when the time comes for valve adjustments.

I am trying to find a local wrx owner with a stg 4 and fmic who will let me swap in a 2.5sti block onto stock wrx heads with us sti cams. I want to see how far we can push it with nothing other than a block swap and matching cams. It seems that most people who are swapping blocks are also swapping turbos at the same time. Think your vf34 or 22 spools late on the 2.0? Imaging what it would do on a higher compression 2.5. Maybe faster than stock turboed wrx and make more boost to boot. Torque is where it's at.
Btw, I would do this on my personal car, but my wife likes driving it the way it is, so.....

I'm curious as to how much more alex has vs this engine

Alex has a sleeved 2.2 case. 2.5 crank.. special pistons and rods. 2.4 displacement. The same motor thats in his car has been tested for REALLY high HP. Vishnu also has one of our 2.4s

His motor can just take more abuse than this one, they should make the same power on a turbo set up.. BUT his you could say, throw a 200 shot of nitrous on lol :cool:

Me too, but its just neat to know that if anything were to fail on your motor it might as well be the case halves themselves LOL

The sleeves and internals are fine, the subaru engine design is the limiting factor. But we havent been too crazy with subarus yet in the USA.

And Alex, Im trying to convince Ron we need a new shop car. We have a 2.5 RS shell... 02 body style just sitting there waiting for parts.

I want to put in a closed deck & sleeved 2.4 (same as in your car). Lil built 5 speed tranny, etc etc... BUT it will be right hand drive :D

Hehe,

You should build a GF8 wagon with your pimp motor and 6MT. ;)

The car will weight in at about 2400lbs if you strip it. ;)

That car will fly. And, you can fly with 4 dogs in the back. ;)

5250 Can I get an Amen!? :cool:

Thanks again and YES...you can surely get an AMEN:)

Hey mike what do you know about the cranks you guys are using? DO you guys treat them anyhow? Are they up to the task of high hp levels from the factory? And have you machined any of them down to balance and lighten them at all?

Just curious, as well has anyone bothered to build a billet crank yet?

All cranks are checked for straightness. First, they are balanced to 10,000 RPMS. The journals are checked and polished. The factory crank is actually quite a nice piece, altho we are unsure of the material... We can say they are a one piece forging, and we haven't had any problems to date.

Also, Pauter makes a billet crank... However, its quite pricey.

We checking on having a nice billet crank made. That will be quite pricey.

The $3,500 is for the shortblock. Headwork is an additional cost.

ya i know been talking to mike about your guys work he said you guys are top notch just need money now :)

Wow this just may be the motor I am looking for. (when I have the money ;)

The fact that it held up to 47psi of boost is even more amazing :eek:

Hopefully a engine like this will be going in my car soon enough ;)

Do you guys also do installs?

How much would you charge for the whole set-up(2.35motor, new turbo, IC etc) ? Thanks.

The cool/sad thing is that that may be what my car will be just like pretty soon. Attack of the L wagons!
