what are the mods you can do to the t78 to help it spool faster??? I not talking about n2o, but there is some internal mods for the turbo. Does anybody now what im talking about ??? There is a somebody in this forum that has them done to theres but Im not sure what there username is. anybody know of this sort?

 

Gordon Monsen perhaps? I believe he has a custom compressor or turbine. You can run a smaller housing on the rear. GReddy has three available if I remember correctly.

get some backpressure in your system.

 

Turbo heat shield and DP wrap helps a bit with Lag

 

How is back pressure going to help?

Get a n20 50 shot spool up kit! i raced a supra with a T-88 and that thing spoled at like "what looked like" 6,000 to 6,500 rpm. Or he was some dumb *** driving his daddys car

 

I just picked up my T78 kit today. I'll have a few pics up tomorrow. I was suprised to see that it was a divided turbine housing. I guess the T78 needs it. Anyway, I'll post pics tomorrow of everything. I "apparently" have an HKS manifold and not the GReddy manifold. Anyone know how to tell the difference between the two?

The greddy is a mitsu turbo! I don't think it's a TO4 flang? If it's greddy or HKS it will be casted into the manifold! Hope you have the same wastgate for whatever the manifold is?

 

The T-78 has a divided T4 flange. The Greddy manifold looks very similar to the HKS SS manifold.

 

how does turbo heat shield and dp wrap help the spool up????

 

by retaining heat in the exhaust, thus keeping velocity (force) high. Downsides to exhaust wrap include thermal fatigue however. I'm about to send my downpipe and turbine housing out to be coated with a 2000 degree Jet Hot coating. The downpipe is getting the inside and out treatment. I called GReddy about a new heat shield for my kit and was given no specifics. So I have a local GReddy dealer checking on it for me. If I can't find one, I'll probably use the Thermotec turbine blanket kit. I do believe there's a point where you can retain too much heat under severe conditions though.

for quicker spool up you need to put a smaller hot side, period.. i dont know what type of housing but contact these people they can help you for sure..www.innovativeturbo.com
