Pic Requests for 3.4L SEI engine swaps
I just bought a 3.4 out of a 93 that i'm going to rebuild and put in and i was looking for some pictures of people that have done the swap, along with any advice.

I did one in an s10.
Honeslty, the wiring efforts are not worth the work when your just upgrading from MPFI to SFI.

Re: Pic Requests for 3.4L SEI engine swaps
if your putting it in a camaro there are no wiring changes 
because you wont be using SFI, youll still be a MPFI

Re: Pic Requests for 3.4L SEI engine swaps
by the title and my understanding of it, they wanted to swap the ecm/harness too?
Guess the original poster needs to verify which swap they are wanting to do.

Go to the middle link that pillsbry posted. That is almost a step by step of what you need to do.

Re: Pic Requests for 3.4L SEI engine swaps
The easiest swap uses MPFI, the swap involving SFI(sequential fuel injection, which btw resorts to multi-port fuel injection at high rpms because injectors can't keep up with the pulses) is a lot more involved, and not worth it it at all, besides, the 3.4 intake is inferior to the 2.8/3.1 intake, ironically...
