Turbo Housing

[TYHOGG]

Looking at the pte turbos, whats the difference between the syty and regular exhaust housings? I want to run an s-cover "same i used for mock up", cause it clears the a/c no problems. I notice they do not offer the s-cover in the 72 or 74 turbos whats the deal? I'm looking to run consistant high 10's and both of those have been proven to do it. I think the 76 might be a little large. Any other options?

Thanks,
Adam

If the outlet faces downward then the "S" cover will work. I believe that is the 4"/2.5" cover.

They have an S cover... GTQ72S. I have one. They don't make it in the 74 though. When I got my GTQ72s they convinced me that it would out perform the GTQ74.

Re: Turbo Housing

In regards to the different compressor housings; the "E" cover is 3" inlet 2.5" outlet, the "S" Cover is 4" inlet 2.5" outlet, and the "H" cover is 4" inlet 3" outlet with roughly 1/2" larger major diameter on the compressor cover..

Since you mentioned exhaust housing, that has nothing to do with anything you expressed conserns with. Anything other then the syty specific turbine housing will require a custom downpipe and or adaptor from T3 to t4.

Re: Turbo Housing

I apologise for the confusion. From what i have read here on the board pte offers a syty specific exhaust housing. Is it my understanding this exhaust housing moves the turbo inlet away from the motor and more forward? Does the standard housing do this too? The pte i used for mock up was a 67dbb syty turbo it fit with no issues, although i have not seen anyone run 10's with that turbo.

Mike - If i'm understanding you correctly the only differnece in the exhaust housings is, the syty is a t3 flange (bolt to stock, atr/kennebell headers) and the standard housing would be a t4 which would require an adapter, correct?

John - is your 72gtqs a syty exhaust housing? I'm looking to clear the a/c with the larger tubro.

Thanks for the help guys,
Adam

Re: Turbo Housing

My 72GTQS has a SyTy exhaust housing. It is currently on ATR headers with a PTE down pipe. I am redoing my motor a will using RPM headers.

Re: Turbo Housing

Just to be absolutely clear, to the best of my knowledge (and I think ghettosled's post is in agreement), there is only ONE "PTE SyTy exhaust housing" and there never has been any other. It is .85 A/R and everyone uses it.

Without it, you must use a goofy adapter (for instance to use a GN turbo) which is leak-prone or a custom header/downpipe which is over $2,000, minimum.
