50 trim T3/T04E vs GT30R ???
Whoever posted our dyno sheet there...
That is not pump gas and the reason it looks like it spools late is because if you read the dyno sheet it says late RPM roll on to reduce stress on the motor. Meaning that I didn't go WOT until I got well past the the peak VE (torque) of the motor.
I'll chime in because I've tested over 10 different combination of turbo's for our turbo kit. I'll tell you that the GT35R with a different turbine housing (not Garrett's) spools awesome and makes a ton of power, pump gas or race gas and it beats anything T-series for spool up and power. The T3/T04E 50 trim (BCI-18) T31-76 trim wheel works very well on a street car and you can't beat the price. The GT30R trimmed turbo that I ran spooled very similiar to the 50 trim but made a little more power. It's not a great leap as far as power and spool up go but it is improved. I've been playing with a similiar sized GT non ball bearing tubo and it's responding very well. Spool up is only 300 rpm later and we're making 75whp more. The GT series can be configured just like the T-series, different housings and wheel combo's. A properly matched GT series will outperform the T-series turbo. BTW the stuff right out of Garrett's catalog is not always configured correctly for our 2.0L engines.

I also agree with Martin.
We have been testing some different turbo set ups.
We found the straight Garrett stuff is a little to laggy for a 2.0liter, but we are having someone else build the GT35R now and they spool really well and make a lot of power. Both on pump and race gas.
We expect 420-430whp on 91 octane pump at 20psi. We could run more boost, but there is no reason to push it on pump.
We have also found the GT30R will make more power than the 50trim. It will also spool slightly faster. So if you have the money I would go with the GT30R.

3037= too expensive
gt 30R= might not be enough power wise but great spool
gt35r= great power but horrible spool for me...
If somebody could cut down the spool about 500-700 RPMs(from rnrs 4700-4900) it would seem that it would be the obvious choice... a little more lag then the gt30r but the potential power gains are well worth it...

Not to be mean but I've put in countless hours on our dyno, a ton of time swapping out turbo kits and thousands of dollars on turbo's testing them. The reason I'm doing this is to offer the best kit possible for EVO owners. I've already given out a little info/hints on another forum and other vendors took that information for their own use.... you see where I'm going with this? If you want the best turbo combination give me a call.

Considering quite a few people have run 115+ MPH traps on the stock turbo with bolt-ons and cams, that's not too impressive.

No one is making anything like 380 whp on a 16g on pump gas. Your comparing the most powerful race gas tuned stock turbo EVO's to times that are the average of your typical racer.
The 50 trim tuned to the same degree as Buschurs stock turbo EVO would be running plenty of 10 second passes at 129+ MPH.

I still would be very dissapointed if my Evo ran 115 MPH traps with a 50 trim TO4E even on pump gas.

Turbo Trix is making 360 WHp on a SAFC with a 16G and pump gas, with the AEM, they make 380, it can and has been done.
