Twin Garrett GT2871r
Hi, I have a twin turbo kit that rps made 5 of. I'm upgrading the turbos to gt2871s. I have a 94 auto twin turbo. The gt2871s i'm using have a .64 hot side. Does anyone have any idea what kind of hp and response I can expect?

Twin gt2871s
They both run at the same time. They are mounted on seperate tubular exhaust manifolds.

As far as response, you won't see much useable boost below 4000rpms. Of course, these estimates all assume your engine is in good shape. FYI: Here are a few of the links I used for my estimates: http://www.tweakit.net/shop/product_...oducts_id=5888 http://www.elitedubs.com/index.php/t....msg18582.html http://www.ztechz.net/id1.html

Hi, thank you for your valuable information. I can't wait to get them on. Do you know of a source for earl's pre made stainless steel hoses?

wondering
How much hp can an automatic tranny hold before you should start looking into beefing up the tranny? And I guess the same goes for a stick? What kind of hp can a stick hold? And last bit, driving a manuel with a single turbo, pushing over 500, does that require a certain level of skill? To me it would seem thats not something you can just get up and go do. Correct me if I'm wrong.

Yes, 500rwhp+ with a 6spd does require a certain level of skill. A forced-induction vehicle is variable-horsepower (depending on boost level). If boost hits while you're cornering, it's almost completely unmanageable. With lots of track time and lots of patience you can learn to keep it off the walls...

Everthing is starting to come together but i'm not sure what size an hose I should go with for the watercooled turbos? Just bought 2 10 pound nitrous bottles. Anyone have any experience with a 2 stage setup?
