So i have a 90 ls motor that has 80k and is sitting in my 91 si that the owner before me installed. It takes forever to start unless it is completely warmed up, it now wont even drive with shutting off when i start to hit the brakes, it does need a timing belt but I am going to try and get that done tommorrow. I want to know whats wrong and if its worth to keep if I plan to turbo later or should I sell it for an 94 ls or civic then swap. I know theres alot of questions but I dont know what to do an I really love the rex, im just debating on wether or not it is worth to keep. I have also read all the forums and none of them seem to have my problem, and please done tell me to check more. Also this car is my dd so I would like to get it working quickly so I can sell it or drive it.
