I have a 2003 wrx with 128k miles. Its all stock and most likely haven't been abused. From reading on the interwebs, it seems generally accepted that 02-03's stock blocks and trannys are good to handle about 300whp. I'm thinking about maybe getting an uppie, TBE, injectors and switching it over to E85. What's a good turbo that will get me to 300whp? I plan to buy a used one. 18g? One of the IHI VF's? Can this even be done on stock cams? I am not planning on swapping those out. This is my daily driver, will not be raced, so I need fast spool.
you could do it, with a 20g easy. I like the word "uppie" that is what I will call it from this point on!
"uppie" FTW!!!!!! If you are going to do that much, I would also maybe look into a header. I have a friend that put down 298whp @ RS with 18g on his wrx.
Biggest thing is what you want to consider 300whp. I can tell you that there is a night and day difference between 300whp on RS's dyno compaired to MAP's dyno. STI's with 20g's on them make 300whp on RS's dyno. Russ
This may be true, but.... my 06 WRX (2.5l) with a vf39 made 290 whp at rs motors, a 20g w/e85 should get you there (even in a 2.0) with fuel/exhaust mods. Are you going front mount or top mount?:biggrin:
Yeah I mean a Mustang 300whp, like Ron's, not dynojet. I'm keeping the tmic. Maybe a bigger STI scoop. I'd like a bigger core, but it's not in my budget.
You can easily get around 300 hp at the wheel, but at a 128K you're taking a gamble on the longevity of the block and transmission. If a simple IC set-up is not in your budget and this is a daily driver....then do not take a leap like this. just my honest advise. FP68HTA- you'll get 300 with E85 for sure!
fp68 spools about an 18g on the 2.0 from what I've seen. and on the 2.5, the 68 spools a bit quicker. vf39 + e85 can net you about 300 @ RS. the ft68 + e85, probably 330+ the 18g on e85 made 340.
16G's have made WAAAY more than 300 on DSM's/Evo's, I can't see why they couldn't do the same on a Subaru. :biggrin:
My old car-16g (510cfm) 2004 wrx with all supporting mods did 260hp/254torque on the Mustang dyno at 20.4 psi- on pump gas.
Ive ridden in a 20g wrx, (2.0) it was sort of laggy, but once it spooled, it felt worlds faster than pete's 20g sti. (and it beat it a time or two) remember those old days, 3van?
evan's car was incredibly fast....but didn't the bottom end start to take a crap after a few thousand miles of that abuse?
Not that I recall, He shredded a trans or two. Then traded it in on an LGT. It had a pretty crap poor tune on it though, it was way back when DB just started tuning subarus.
gotcha...it was fun following him in that wrx on a fall run...Once that car would spool he was gone!! lol
We had a 300whp 20g STi come over from RS making 304whp on his dyno if I recall that was the exact number, and he made 313whp on our dyno without changing the tune or anything. That way we can get base numbers. Switched him over to e85 and brought him up past 400whp. Our dyno on the lowest correction is not to far off from a mustang. If we do STD correction, it is about a 20-30whp difference from Ron's dyno. As far as 300whp, that will be easily enough. I make 411whp on my Stock block 179,000 mile 2.0L WRX with E85 and a FP 68hta. My car holds boost all the way to redline and doesn't give up! Power graph is a little wavy due to my MAF being maxed out, Fuji and Travis Dagen approve I suggest the following setup: Pump 255lph Injectors (740's ATLEAST) Grimmspeed 38MVS Up-pipe Grimmspeed Boost Control Solenoid Downpipe of your choice STi Intercooler E85 FP 68HTA MAP/Jordan Tune :yumyum:
I guess i'll need to talk to you Adam, when i finally make it out there to pick up an lc1 cable from you guys 47lb/s on hta86 does sound yummy :yumyum:
Sounds good, swing on in! Dyno will be cleared for ya and the e85 jugs will be filled! haha. Got pumps, injectors, up-pipes and everything you need in stock! 2.0L and the 68HTA are like peas and carrots. My car loves this power band and fuel. E85 was MEANT for subaru's in my opinion. LOL. I have ZERO knock count, and my motor runs smooth as can be. I just did a 2200mile trip to Michigan and ran straight E85 the whole time!
