3.8 to 5.0 swap

98mustangv6 · 08-03-2009

Hi everyone. I have a few questions for you. I have a 1998 mustang v6 and i am in the process of doing a 5.0 swap. I have found a donor car and its a 93 thunderbird. Will the wiring harness fit in my car? Also will the ECU work in my car?

you would either need the the computer & harness fromm the t-bird or a 5.0 mustang.....

yes you will also need the MAF.....

the T-Bird parts will work but for the best performance the 5.0 mustang computer will better

FYI the motor in the T-Bird is not a H.O.

H.O. or not, im changing everything in it before installing it.

Well it won't run like a Mustang, it'll run like the underpowered Thunderbird.

You also have to change the k member to accept the pushrod V8.

Well would it really matter if i rebuild it with aftermarket parts?
