86-88 engine in a 89-92 swap i have questions

[michaelskeet]

has any one ever used the 86-88 turbo engine in a 89-92 NA body? what changes had to be done? ECU? engine mounts? Transmission? any response will be appreciated.

i'm doing the same thing right now. i bought a 89 turbo auto ECU and 89+ wireing harness that i will have to splice some connectors on. i'm going back in with the engine this weekend and try to get it running so as for now i think we areon the same page. i will let you know how it goes come this weekend.

as mentioned, ecu and harness will have to be swapped.... along with engine mounts. transmission fits the same

Don't do things the hard way like I did...

Harness, ECU, get rid of the w58 stuff and go for the r154. Here's the link for differences between the both: w58/r154

I'm also switching in a 3.9 rear diff on my car, but that's not absolutely necessary.

Don't forget, some of the sensor connectors change as well, mostly the temp sensor ones.
