Help with turbo teg
 

Ok my friend has an ls completely stock with a turbo kit on it. The motor sounds like it putters when it idles...wanted to know if it would be a reliable car to have. Hes running 8 pounds on stock engine. Help please

Sounds like an awesome car!!!!!

This is a very vague question...more detail needed. Have you ever done a compression test on it? How many miles on it? Who installed the turbo kit? Is it all quality parts? Who tuned it? Many more things need to be answered before we can say if its even a decent car.

what do you mean when you say it putters?
like is going to die unless you give it gas or like its running on 3 cylinders?

the turbo kit was on the car before he got it. he said something about it being a rebuilt ls. its an ebay turbo kit also. i cant reall explain the puttering. when it idles it just idles and backfires almost. its wierd. it might need a tune n some valves. but i also heard its not good to boost a stock motor

Stock motors are fine to boost so long as they are tuned right...sounds like too much fuel to me. First off, the ebay kits suck. Second, they usually "tune" with a missing link. Throw that thing away and get a real tune.

The timing could b off also. Is the CEL on?

what injectors does he have? does e have a wideband gauge?

put some better plugs in it, mess with the timing.
