Re: Turbo(s) for 2.8 I6
sorry.v Oh yeah, defintiely, the t04e 60 trim is the biggest of them all. It's certainly kicks ***! 70% brings it to over 450 HP (if you don'T mind boosting 20 psi)

Just for sakes of comparison, the t04B H trim is comparable. 70% also brings you in the 450 hp range when boosting 20 ish psi. Ok, accoring to them, it's 4-5 % less efficient at peak but still, i used it a lot and it really made B18C's, H22's and 7MGTE's scream when used wit the proper turbine side.

No problem man. Oh it won't take 20psi to make 450bhp lol! The bigger the displacement the less boost ya need woohoo!
I saw a 7m-gte making 4whp/468ft-lb @ 18psi. Too bad they're 4valve & 5/6m's are 2 valve. (Atleast they're big valves lol)
I really don't see any reason why he couldnt make atleast 550bhp @ 20psi on one provided the t3's turbine wasn't too bad off. Maybe swap it for an .82 A/R. It's been done before.
I just think it's going to be a hella fun project. One of the older guys at school passes a beater cressida around to some of his other friends. I'd love it if he put it in my name & left it in the driveway. lol Cressida ftw woot!
btw sleeper from hell outside of an early LS400.

Okay, so lets say I get a stock as a rock 7M-GE or just the head on my 5M. I'm going to have to assume these big horsepower numbers you speak of were NOT on stock engines...

Re: Turbo(s) for 2.8 I6
The thing with swapping a 5/6m-ge with a 7m-gte is that it's a hell of alot of wiring. More people turbo their 5/6m's than swap 7m-gte's. http://www.7mpower.com/7m_buildup.shtml a quick guide if you're wondering.
What's going to kill you is seeing guys make more torque than horsepower even up to 800rwhp. lol! Stock cams are pimp mid-range.
That's so sick.
On a good condition 5/6m-gte you can still make 400rwhp aslong as it starts in good shape. Lotta torque. Whole lotta torque.

Re: Turbo(s) for 2.8 I6
woah. Goofy dyno chart!! Goooooood torque down low!!
Yes, it's sick... Especially when tuned at 12.5:1.
safety margin: none I wonder how long it lasted!!
but yah, the 7MGTe we just did is bone stock with 550 ccm's and that .68/.70 T4 H trim with vertical flow intercooler at 12 psi definitely makes 350 WHP as per my butt dyno. Can't wait to test it on a real dyno. THe guy just bought another 87 supra, identical colour and all, but 1JZ twin turbo and i think we'll single turbo it too.
