I think that hits it on the head. You can definitely reach 300hp with a 2.0L, but it all comes back to how you want to drive the car and how you want it to feel. I like my 34, but if I do anything else.....motor wise at least, it'll be a 2.5L. You can't beat the torque difference, and not to mention the greater possibilities of future upgrades. I miss my STi.

 

hey brandon, do you remember any of the tune results for the 2.0 guys?? i remember it was kinda dificult to hit the 300 mark.

so far i read some people say 18G + meth injection, or a 20g. sounds like the car is gonna be a real dog in the lower rpms.. do you care about spool time? for a daily driver, i definately would...

 

It all depends on what 18g you go with. A TD06 wheel spun 18g is too much. A TD05 wheel spun 18g isn't that big of a combo on a 2.0. Look at the td06 numbers though. Jess, Brent, and Jimi. They are averaging about 330ish to the wheels. Keep in mind that's on a 2.5.

So to hit 300 on a 2.0...you would need to do some sort of meth injection. I know for a fact (since i was gonna go this route) Jarrad from PDX wouldn't feel comfortable tuning a 2.0 to 300+ without the guts needing some re-enforcement. But that's not to say it can't or hasn't been done.

There's a power section on NASIOC. See what some of the EWG 18G guys who are sportin the 2.0. ALOT of them are gonna be running a methanol kit.

As far as your transmission, if you clutch upgrade, keep in mind our 2.0 tranny's aren't that strong. So the harder the clutch, the more prone you are to breaking gears. And injectors, i would go with something in the 800's. Although i think Jess has 650's on his TD06. That just depends on how much leg room you want/need or your future plans.

I really doubt you would need forged internals. I've seen gt30's with .72 AR run all day long on stock internals and as long as you're tuned properly, wont have anything to worry about.

On this set-up i would recommend a 3 port boost solenoid instead of EWG. And as for TMIC or FMIC...purely preference. Again seen multiple gt35's with TMIC's before and been fine. Just depends on what YOU want.

just my .02 cents

 

I know Troy was right there at the 300 whp mark and around 263 lbs/ft of torque with his Evo III 16G. I think he was running Meth too, and he also did a race gas amp and put down like 325hp. It's possible to reach 300hp at like 6K rpm, but I'd rather feel 300+ lbs/ft at 4k rpm. Does that make any sense? Again, it comes back to what you want to feel and how you want you car to react.

 

^^^i know what you mean.

from a fellow 34 owner...i like the power early.
Brandon is right...it depends on what your goals are
do you wanna turn or go straight. It's a fine line to do both, but can be achieved.

 

Very Zen...

Hey Josh, are you running booster controller w/ your 34? If so, what brand?

good info, but doesnt td06 and td05 refer to the size of the housing, not the size of the wheel?? i believe 18g refers to the wheel size. ive seen this widely confused..

 

I thought it was the wheel, I must be confused. Either way, when people say 18g...there are several routes you can go.

 

I think the confusion is due to the mixing and matching that goes on nowaday.
But originally, the MHI (mitsu heavy industries) 20g had a td06 turbine wheel in an 8 or 10cm housing.
That was considered standard.

But turbo resellers started to mix and match parts. The standard 16g has a 16g compressor side, with a td05 compressor cover and td05 turbine wheel in a 7cm turbine housing.


But then there are offerings that combine parts--a 20g with a 7cm hotside which was originally from the 16g, and you even have the td05-20g which is the 20g compressor wheel with td06 cover and a 7cm turbine housing and td05 wheel.

So yeah, it's confusing because of the mix and matching that resellers do. But I think it's implied that the td06 turbine wheel matches with the larger turbine housing, and so saying td06 wheel also implies an 8cm or greater turbine housing.




If I could chime in here for a minute on turbo selection, I think that, since we have a lot of cool guys on the board, the best bet is to ask for a ride or test drive. I'm sure that no one will refuse you one pull, and so actually driving each is probably a lot better than discussing numbers. I tend to theorize quite a bit, as it's really what I'm paid to do on a daily basis, but when it comes to turbo selection, getting in the car and trying it is always best.

 

^^ thanks!


yea test drive would be good, i drove a wrx with a vf34 set up and it was wayy over my expectations!! i dont even think it was tuned yet, just a cobb ap

 

thats definitely something i'd like to do.

anybody who has a two-o that has upgraded their turbo (if you don't mind of course) i'd like to take up any offer.

and as far as spool times go.. this is definitely a daily driven car.. and I do want to maintain it streetable.

though I have friends that have already planned trips to outer islands the following year for track runs...

i'm definitely not ruling out the consideration of the VF turbos.. just wanted some feedback on anything else that might fit me.. settling for 260+whp is no big deal if I can still drive it daily..

 

If spool up, driveability, and reliability is your main goals, I'd probably go with an EvoIII 16g. IMO, this would be the best compromise between quick spool, higher flow, and $$$ spent. Troy put down some very nice numbers at the previous tune and seems to be pretty happy with is choice.

 

Nice read on the topic we're on

I wouldn't mind lettin you drive my car.
(vf34 though)
