So to all you newbies out there, like me, it's possible to do-it-yourself with a bunch of time and good tools. I just finished my project; VF39 ($350), modded WRX injectors 660cc ($125), Walbro FP ($90), SSAC TMIC ($150), Perrin Turbo Inlet ($200), NGK BKR7E (colder plugs). I was already at Stage 2 running an AP. The final results...243 whp, 223 torque on a Dyno Dynamics Dynometer at DB Performance. They say a stock WRX on their dyno runs 155 whp. Since Subaru states 227 hp at the crank stock, I figure I'm coming in at about 360 hp, 60 hp over a stock STI. Should I have just bought an STI in the first place? Who cares because I wasn't willing to pay up at the time. Having this car to slowly invest and tinker with has been great. I couldn't have done it any other way. If any WRXers need help doing any install work, I'd be happy to lend a hand. Although, I can't say that I know what I'm doing.
Congrats! I am in the same position, but I haven't gotten mine tuned yet. I went with the 16g turbo and a GM boost solenoid to control things though. Did you get tuned at DB or did you just run an off the shelf map?
With a VF34 + FMIC and 680cc modded stock injectors, I made 270whp and 240tq on the Mustang dyno at RS. Stock WRXs make 155-165whp and Stock STi's made 215-225 on it.
^$350 for a FMIC setup? if that is the case then that sounds good...But I prefer TMIC...I just hate all that crudd getting the FMIC... $350 I assume this is eBay right?
I was hoping for more power, but I'm really happy nonetheless. I don't know what to do with all the speed. My spool up seems slower than it should be, even though I've got a catless UP. Any thoughts?
Yeah, I was thinking the same. When are you seeing full boost? From looking at your chart, I would assume somewhere in the 4-4500 range? The last car I tuned (td05-18g with a GM BCS and EWG) could hit 19psi by 3800 rpm in 3rd gear.
Seeing people talk about new turbos and dyno numbers is making me drool, I'm actually staring at my new 16g right now...
Where have all you guys got your cars tuned at? I am sitting with a toned down base map and all my parts in after this weekend. I put in a 16g EVO III turbo, modded injectors, GM EBCS, Ebay TMIC, Samco Y and turbo inlet hose, and a walbro 255 pump. WRX1 did my last tune, but it sounds like he isn't available for a while. Can anybody recommend a decent place that I can get tuned at? I need to release the chains that are on my car right now...
dang! looks like a new turbo might be in the future for me! thanks for the post i just hope tom (walloftv's) is willing to experiment tuning with an aftermaket turbo/injectors...
^^what he asked... and what difference in WHP and WTQ you gained from it. They should've made a baseline and a tuned comparison for you. Did they?
No race gas tune. I don't think that I'll ever be running race gas with this current setup. I'm going to start getting into auto-x and the driver's ed track days at BIR. Maybe when I move into a bigger turbo, I'll start looking at extracting every ounce of power and using race gas.
