the stock ecu can idle perfectly fine with e85 and 1000cc injectors. but with e85 and his power goals 1000 is waaay to small id2000 at least

 

I could make an 800hp subie...
Drop in an LS9 from Lingenfelter! woot!

 

You guys are mean. He was just looking for the cost and manufacturer on a part he is no where near ready to buy.....

I am playing by the way. Good luck and I wish you the best.

I have the same opinion I think you are on the wrong platform. Why put 45k into an 08 WRX when you could source a supra for like 22k and import parts from JAPAN!!!!<<<<<notice the F&F refrence.....

 

thanks Deezy, I corrected my statement


were not mean just realist and I am playing too. I am sitting on a ticking time bomb by running a nice size rotated kit on a stock EJ257. Oh but it is sweet sitting in a GC chassis

 

Yea lance told me his runs a 9.71 on his E85 race tune. Call him up if u want to know the details, its not my car. Hit him up though hes always up for talkin to his friends on island. If yall say ill never hit 800hp then how much can i realistically push reliably. Im going to do a PPG transmission for sure probably a 5 speed with straight cut gears (hopefully sequential), a cosworth longblock *i will bore it out and sleeve it bigger if i need to. Im not really worried about the cost but i dont want to over pay.

 

reliability depends on alot of things. one thing to remember once you make all the power you can and do a ppg box, you still have the rear and center diff and axles to worry about.
just remember one thing this isnt going to be anywhere near cheap when said and done you will be throwing at least 30k at this car to make the power you want.
shiet the cosworth longblock is half of that alone

 

Depending on what tires you are looking at size wise you may have to look at upgraded axles as well.

Also taling about the 5 speed and ppg gears dogbox whatever drag racing over 600hp its not the gears that will go but case flex on the tranny.

You will probably need a 6 speed to reduce flex with gears. If you are going to go that route get the 5 speed ratio installed on the 6 speed. Clutch is going to be an issue as well.

Motor wise cosworth logblock sleeved bored ok but you are going to need a huge fuel system, and e-85 may not be your answer you might want to look at like v-16 or whatever.

The size of the turbo you will need to make that power will be so unbelievably laggy you may run crap 1/4 mile times becasue you are going to make that power at the top of your rev range and wont hold it long.

Maybe it can be done and you would have the awesomest subie drag car out there but its not going to be cheap to get there.

Just food for thought. Now I think if you can drive and have the car set up right you may well run low 10's high 11's on less or even less with a lower hp less laggy setup. like say 450-500 WHP and now that is possible and can be done way less expensively.

 

To the Op

Expect to put down over 35k if you want what you are talking about parts wise. But dont be thinking your going to get your whp numbers. What you want is about what I have. But I'm not running e85
I'm in the 480 to 560+whp range. On a dyno that reads 210 for a stock STi. Car is in the shop right now rebuilding the clutch and Sti 6 spd.
As far as DD, My car can pull that. One thing I would frown apon. Buy a cosworth and leave it alone. Your not going to do anything buy mess up a great motor.

 

good luck trying to get better HP numbers than an Evo on E85...they make alot of HP compared to subies

 

Our dynojet here reads low also. A stock Sti reads 240. Only 30 hp more then where ur at so not bad I must say so my self.

 

My 07 has like 40k in upgrades and is only at 500whp. (on 92 octane, could maybe do 700 with the right fuel and larger injectors)

Btw, it idles like ****, stalls occasionally, makes fu(ked up noises, and has been through 3 clutches in 1000 miles...2 were twin disc.

Stock fuel lines and 1000cc injectors will not get you past 450whp, even with 2 walbro pumps.


Once you get in the 500whp range in a suby...nothing is reliable. Camshafts can snap, a bad spray of fuel and you can potentially flat spot a rod bearing or break piston. A trans case bolt can stretch too much and shear off 2nd gear destroying your freshly built 8k tranny.

You have to be willing to buy expensive parts, rebuild trans, or engine every other weekend if necessary.

Be prepaired for your entire car to sometimes slide sideways halfway into the next lane when shifting full throttle into 3rd gear.

Differentials loaded up a certian way, the correct temp. and a little wheel spin on certain surfaces can rotate your car sideways faster than you can blink.
Subarus are rather predictable with 300whp, fun to drive.
Throw in some wider stickier tires, another couple hundred horses, some unsprung clutch discs, torsionally flexy axles, and a stiff body. This is where all that grip and control are no longer anticipated, guaranteed, or easily controlled. It is a whole new game, and now you actually have to know what all of those ***** on your fancy suspension do. You will need to adjust spring rates, compression and rebound dampening depending on road temp and surface type.

It isnt as simple as the rear tires always spin and you have to control the oversteer.

Oversteer and understeer like to randomly pick a leeding role based upon body roll and whitch tire rolled across a little oil in the parking lot last night.

I have been driving high hp subarus for 10 years now...and sometimes it is still unpredictable and scares the shipoop out of me.


If you plan on actually driving your car, buy a GtR or something...it is cheaper.

 

LOL this is a great description of what driving a 500+ hp suby is like.

My buddy let me rip in his 500+ whp Evo.......Completely different story....I think it has somthing to do with the fact that the AWD does not work as well.

 

thanks for everyone for doggin on me. i wasnt aware that evo's usually put out more power than wrx's like i said im new to this. if i dont hit 800 then thats fine. it was just my goal. that is the funniest description of driving a high wheel hp subie. Lance let me drive his once. i think it would take a while to get to know it but it does sound like fun. either way im still gonna build it up as fast as i can make it. if yall are sayin that 500 is a realistic achievable goal than thats my new goal. too easy. im not tryin to be difficult to work with it just seems like everyones got everyones got jokes and not too many of yall got suggestions. to those of yall who gave advice, thanks and i will be using it. i try to build the car to handle the power before i build the power so its probably suspension, trans, fuel, exhaust, cooling, axles, motor/transmission mounts and everything else before the long block and everything else. oh PS - Xcceleration
