looking for a street turbo the one that seem better for the job is the t78 from greddy have a new street portet from pettit racing fmic 850,1600cc fuel rails and other stuff looking for 450.465hp on 15 16 psi with pump gas let me know what you guys think for the t78 for the job or maybe other lets heard.
thanks

 

The T78, the PT67 Qtrim, the T4 hotsided GT35R from A-spec, the AP-88 kit from A-Spec, the AF61R from Davinci. Hell there are a few turbo's that will do that. I hate to be the ******* to say it, but use the search button.

do you think that the gt35r from a-spec will produce 450hp at 15-16 psi even with the t4 hot side? i think the best for that job is the t78 and already search for info just looking for opinions of what turbo people will use for that amount of hp and why.
thanks

 

People are having great results with the Davinci Motorworks (DnR) Af61R turbo.

 

It really seems you want to use the T78, you said a few cars over there including another FD run that turbo setup.

So you should go with it.

As stated before , theres quite a few turbos that will yield what you want, Some with a bit more lag than others.

 

I made 436 at 16psi on the T4 35R

 

great numbers and great turbo also but here in my country there is no many choices to repair a turbo like the 35r ,so i thinks ill have to go with the t78 kit that is a more simply and trusty turbo and will deliver the number i want.

 

Was that on Race gas or Pump? Nice numbers man!

My goals are the same with same injectors on a dual pump independent fuel setup. I will be running a GT40R.


What kinda tires you gona run to hold that HP?

 

nope that was on 93

 

13B Maniac if you really are looking for 450 on a streetported 13b? Its not too hard actually, I have seen good results using a t-04 custom done Garrett/Airesearch turbo I got a friend who makes them specific to your motor combination its really a great option especially if you want that off-the-line Torque!

 

you made that with a large street port? I cant wait to port my motor I made 403 at 15psi on stock ports. 450 at 15psi on pump gas is plenty for me and right around the corner...

 

..the greddy t78-t88 are antiquated pieces of ****! D-R Autosports AF61 or something from Gotham would be much more efficent and cost effective vs. the greddy stuff. You would think with Greddys resources they would be up to date with turbos? oh well, if they sell..sell them!

thanks, Ron.
