I am seriously considering doing a twin turbo set up for the TGP, Just curious if any body else has tried it.. I installed the manual (mock up only) and there might be enough room for a GT2876R behind the trans or most definitely under the car, Just curious what you guys think.. I know it doable...  :icon_twisted:

Sounds like it would be cool.

DO EEEEET I would love to see that.

If I were you, I'd probably just upgrade to a larger single turbo(that's my plan for later anyways).

Twin turbos will spool up faster and if you size them right Adam you can have one which will give excellent off the line response and then a larger one for top end power.  Like the 3000 GT VR4 or other imports.  That would be awsome but I'm too chicken shit for that kind of thing with my DD.  Oh who am I kidding I'll spring for it if you make it;)  I would need a manual trans conversion, oh wait I sold mine to you! hahaha

GT3071R plus 3400 top end plus 3500 UM, plus (KAZ tune)...........wont say I'll be the fastest, but until it blows up I'll be trying. :icon_mrgreen: (I'm taking all of March to "finish" this car) will post some pics as I am finishing it.

Besides for the cool and wow factor, which both I would gleefully give, I guess my only question is why? It seems like you would have much more piping, more oil lines, another turbo, etc.... Just seems like a lot of money that could be put into a better single turbo setup.

Well for one the crossover cluster fuck on our cars is hardly optimal for merging exhaust gasses to make the most optimal power.  By having a TT setup each manifold could flow to a turbo getting rid of all the exhaust gasses bouncing off each other on the way to the turbo.  Then the exhaust can go straight out the back off the turbo and not down by the powermaster.  Sure another set of oil and coolant lines big deal,  You can run a turbo without coolant lines if you have proper oil cooling in place and maybe even higher capacity of oil.  It would be more complicated but I give Adam props for thinking outside the box.  I suggest you guys read a book called maximum boost you will learn all the ins and outs of turbocharging systems.

Single turbo = lag    I have been down that road before.. I would like my car to spool before 3-3.5k..  I am thinking of using the stock turbo + a GT2876R for the best results.. Like Ken said one would get me going down low and the other would come in @ 3-3.5k and get things moving.. Plus 400hp at the wheels would be easier to do and less strain on the engine... Not to mention I would have the only TTGP in the world... 12s in the quarter would be a lot more doable also..   :icon_mrgreen:     I also just started a project on my IROC-Z,  I have a used Twin Turbo set up for it. I am planning on boosting a 434 CID motor. With my calculations it will make 750rwhp @ 6psi of boost with 12psi being the max...Ummm  can you say fun....

Damn!

Adams goin for 9s....

Owned it for the last 4 years, and have read it through and through several times  :laugh:

Yeah, I totally agree, however, and correct me if I am wrong here, would the 3500 heads enough flow enough to allow that much through? Then you got to take the intake manifolds into consideration, which are crazy bottlenecks. However, if he is going for that fast of time, I'm quite positive nothing will even be remotely stock about them.

Also, if you have a smaller turbo on one bank, and a larger on another, wouldn't you experience a slight pulsation in the air from the turbos since one would flow xCFM, the other flowing a larger xCFM?

This is how the exhaust would be planned out.
