5/2009- I just bought this 1987 CHEVY SPRINT 3 CYLINDER TURBO for fun. It actually is pretty peppy. I has a lot of rust and needs body work but not worth the investment. Going from what the previous owner did to it is as follows, not very detailed but you get the idea. It has an LSD. Currently running 5-7psi on stock wastegate and blow-off valve on the stock intercooler. It also has stronger aftermarket JDM axles. Right now I am trying to fix her up to look presentable without breaking the bank. She starts right up and goes but I want to boost her up to 10 psi since the motor has some work. At 5psi for a 3 cylinder she boogys.
