'98 S10 Blazer TBI

Will the TBI from a '98 S10 Blazer work on my '89 4.2 or is it too new?

If it's from a 4.3L then it'll probably work. I think it's primarily about the displacement being close enough to the 4.2L that you won't need to have the PROM reprogrammed. The computer will learn and adjust to the slight difference in displacement.

In 98 blazers did not have tbi, they were a form of cpi.

it'll work... but it's best if you have the WHOLE Blazer to pull all necessary parts from.... engine, computer, harness, etc.... basically everything under the hood (and under the dash) that's directly related to that motor running. 96+ is OBD-II so there's more electronics than 95-, but it's still doable.

basically, you need to make the engine/computer "think" it's still in the blazer it came out of

Thanks for the help. I will pass on this one and look for an older one. I'm not looking to swap out motors.

oh sorry... reading the thread title and the fact that's such a popular swap (tbi s10 blazer engine) I thought that's what you meant
