Something is really wrong with my car, ITs ugraded to the point untill the single turbo. Somethign is wrong when I try to drive it. IT stalls and back fires very badly, I changed my alternator and got a new yellow top optima battery and even changed spark plugs and injectors, It starts fine, but when I try to use the brake or anything electrical the car will turn off or almost turnoff and won't even move, I have no idea whats wrong and I don't want to take it to the dealership because they will kill me on the price,
I hope its not a blown engine, but what else could it be?
please help!

Why did you change your alternator and battery?

So you are saying that you put new injectors in, and since that didn't work you think the engine is blown? You never did a compression test?

To me, it doesn't sound like a blown engine, but you haven't given us much to go on either.

Garfinkle said he had a motorcycle to do that after he painted the frame . The fix was to clean the paint off where the GROUND wires were . May be you are not grounded well .
