I'm running 2.5xtr "Polka Pickle" on E85 on 18psi on stock TMIC. On Fine Line imports mustang dyno my car made 379whp on a cool day. On a hot day it made 360-365 WHP, pump gas it made 330-340whp. I would think the torque is going to be really nice on that 18g, can't wait to see results. Most people always go with the 20g or the 30r turbos. How much of a upgrade is the 18g from a stock 2007 STi turbo? Keep us posted on the tune, GST's dyno is a tuff one.......

 

i originally wanted a 20g-xt but with the stock tmic.. so mike told me to go with the 18g-xt he says its the older 20g but with a lot better response i took his word for it and got the 18g-xt i will be getting it tuned tommorow so i will let you guys know the results..

 

You get tuned yet??????

 

i want to know as well.

 

take a vid!! I wanna see lol

 

My 18G-XT on the 08 WRX with 750cc injectors, 08 STI FP, FMIC, Catless makes 315WHP on 91 @18psi on a Dynojet. (330/342 back on the East Coast with 93 @21psi) It's an absolute blast, spools quickly and holds. I'd love to find out what it'd be with E-85, but living in Carmel I haven't found any local to warrant the upgrades necessary for it (and tune.). Also, I have over 94k on it and it's seemingly reliable (knocks on wood) for the moment and I'm stll on stock clutch/tranny. Afraid to push it any further, but it's a fun turbo and a huge step up from Stage 2. On the street, I rarely feel the need for more power, and I've been on this turbo for 35k+ miles...
