Default GT-70 Turbo
Couple questions. I am looking at a car I found for sale. It has a GT-70 Turbo rear mounted. I do not know much about turbos. I will say that up front. How good are the GT-70's? Also what kind of reliability can I expect with a turbo as compared to a Procharger? (Professionally installed). How will the rear mounting affect my ground clearance? And last but not least, how much worse is a turbo for a 6spd as compared to a supercharger? Thanks for the enlightenment in advance.

how about more details if you know any; motor, mods, etc..
It makes a difference if its on a stock LS1 or built 408.
What else besides the turbo kit; intercooler, fuel, etc...

That t-70 should work fine with that and it is a good product.

Any answers to my other questions? About it being a 6spd or about the clearance on the rear mount? Thanks

On a stock ride height car, its not an issue. If you are lowered, then you have to be careful. One of the biggest drawbacks with the 6 speed is that w/o a 2 step, you cant build boost before launch. IMO, the turbo will start to boost later, but will be at full boost faster than with a supercharger. With a 2 step though, no drawbacks.
Alot of fun with the 6speed too.

Something most people use just for drag racing. You cant have cats and a 2 step. It will ruin them quick,fast, and in a hurry. I dont really a have a good technical explanation, although I'm sure if you search, you will find it. Sorry.

Its a rev limiter that you use when you want to launch. You give it gas and when you hit the rev limiter, it bogs the engine and creates load which buuilds boost. Then pop the clutch and go!
