Default Road testing GT Motorsports 2.8L

I bought this 2004 STi from my friend a little while ago and finally had a chance to fly out to Virgnia and pick it up. It was assembled by Andrewtech and tuned by Phil at Element Tuning. 2.8L 35R with the Hydra as you can probably guess.

Anyway, some people thought it was a little crazy to drive the car from right outside Washington, DC to west Texas but the car made it fine. I averaged just under 600 mile in the three days and capped it off by taking it up to a very high speed on a Texas backroad just to make sure it was still running.

It just seems like there are a lot of guys out there afraid to put serious miles on their built motor and I'm not one of them and this stroker seemed to handle them fine.

I'm moving to Nebraska here in a few days so we'll see what another thousand or so miles feels like.

-T

PS: I should add that the former owner broke the motor in right and that while the car was up at Andrewtech one last time before I left the state a few small issues were fixed including replacing the waterpump and alternator. I also asked them to do a compression check and the numbers they told me were: 125, 125, 130, 130 which sounds good to me.

good job! Glad all is working well for you.

Im not afraid to put miles on my engine either. In my opinion, the more miles the better anyhow to ensure all kinks are worked out of the system and to season the engine some before going for a serious tune. Also helps loosen the engine up also imo before the tune, which should make for even more power.

Sounds like you got a nice car. What most folks don't understand is that at cruise there is no more stress on the motor than there was stock - at WOT, big boost, and high rpms, however, that changes.

Hell yeah buddy, I'm glad you're enjoying my old car!! It couldn't have gone to a better home. I can't wait to hear some more numbers from the strip and to see where you choose to take it from here mod-wise. I'd love to see that thing in some magazines too!

No no Mostly all cosmetic stuff for the Lexus, I just need it to get me from A to B

Travis and I were just talking about what my next project car will be though. It looks like it will be a C6 (or C6 Z06 depending on how well I'm doing in the next few years) LS engines ftw!

It won't be for a while though, my new house will be the next thing that I'm going to be working on modifying

Off topic question how high can the 2.8l rev? Second what kind of headwork is done this work?

I rev it to 8k. Contact GT Motorsports out in Cali if you want to know exactly what they did to the heads.

Whats the torque like? Have you ever driven a stock STI so to be able to compare the two.

You can't compare a stock STi to that car. It would be like Mike Tyson fighting an infant.

I think I still have some somewhere.
On 93 octane:


On 110 Leaded:


I think KPW plans to retune it for C16 eventually, so expect to see over 600whp on the 35R setup and those injectors. That motor has plenty of room left in it, it was built for 60+psi.

Ye gods, that thing spools like my VF30, except with double the power! Must be fun as hell.

It is except for the part where I'm in Nebraska now running 91 octane with ethanol mixed in. I need to get a retune for that + c16.
