T-76 turbo is OLD School Turbo stuff. We can certainly get that if thats the route you want to go. However in my personal opinion and Suggestion I'd strongly recommend the newer 'GT' series turbos. The compressor section and housing has been updated with newer technology parts making them much more efficient than the old 'T' series everyone is familiar with.

Also, depending on what you want to spend, ball bearings are making a very big splash for lower spool/lag and even more efficiency. They are more in the dinero department but they sell like mad.

If you are familiar at all with PTE's turbos, I can guarantee you exactly the same turbo they sell (they are one of our suppliers) for less than they will sell it to you.

I'm not quite sure what you would like in terms of exhaust housing setups but lemme throw out a couple of examples and expected HP rating with the associated turbos:

(both of these turbos are the older school technology compressor wheels).
* TA64 Big Shaft Turbo Supports 680hp and recommended stall is 3300 rpm.
* TE64 Big Shaft Turbo Supports 755hp and recommended stall is 3500 rpm. (This one has a 4" Inlet, the T04s cover and 2.5" outlet).

(these three turbos are the newer GT series turbos)

* GT35R BB (ballbearing) 82mm compressor wheel and similar stalls as listed above. This turbo is also available in a NON BallBearing form, but makes 600hp instead but is significantly cheaper.

* GT40 Available in an 82mm or 88mm compressor making somewhere around 750hp with similar spool as the above mentioned turbos also.

* GT42R Available with 94mm or 102mm compressor wheel making in excess of 1100hp+ (lets not be concerned about spool here).


Obviously we have access to turbos for the smallest displacement imports all the way upto 2200hp HUGE CFM turbos. Tayloring what your driving and what your intentions are is going to be the key in deciding which turbo best fits your needs. To be honest, I doubt any of the ones above are a dead drop in for you. Also, in regards to the stall speeds, keep in mind that those numbers were generated against a 3.8L Buick Motor (as I am pulling info off PTE's price sheet).

There are a number of options for exhaust housings available, in addtion to options for internal wastegates on some of the turbos that cost a little more initially but save you on the back side for not having to purchase and plumb in an external.

However, if you choose to go external, we have almost every manufacturer available for those too.

Prolly best to email me with your build and what you want to do with the turbo and your truck. I myself am building a Forced Induction LS6 to put in my Typhoon and it would be nice to see what others are doing too. This subject is near and dear to my heart as its going to be a BIG purchase for me and my toy.
