nice work ...great pics....been to the track yet?

 

Nope, not since I did the swap. I built the car more for street crusing, and I don't even have slicks. I'll probably take it at some point, just haven't got around to it yet.

 

Hi all !!
Been lurking on this sight for years finally able to post here is wat I have 1998 M/C ls and have doner engine from 2000 Regal GS have everything trans hoses ,power steering hoses , as well as pcm out of regal . I do no not have the wiring harness from a 5th gen z34 so my question is can I use the regal harness and 2nd were do I start ?

Thanks for any help in advance !!

oh and yes that's a 97 gtp in the middle

Quite the collection and quite the project. I know there is at least one 5th gen owner who swapped an L67 into his on this site. Hopefully he can fill in some gaps on the wiring.

 

My current harness is from a GTP, modified by Milzy when I bought the engine. If I had to guess, there's an issue with the connection to the PCM, since the PCM is mounted in a different location than your Regal harness.

 

Great write up !! I am doing same with a 98 monte from your write up are you saying the 3100 injector wiring is the same as the 3800 ??
Thanks in advance

IMO, the starting point is to find a harness for a 3800 monte or lumina in the 98-99 year range. Your efforts are far better spent there as itll plug into the car, plug into the engine (with 2 minor differences) and you'll be set to go.

What you're talking about may be cheaper, but its going to take a bunch of labor to obtain both wire diagrams and modify it to be correct. Modifying harnesses was the #1 cause of bugs & issues in the early days of 5th gen swapped Montes. Just not worth the effort IMO, especially when some years of these cars came with almost the exact same engine.

 

Not sure about the injector plugs specifically, but the engine harness overall is very different between 3100 & 3800.

You need a 98/99 monte or lumina harness to make it 99% plug and play.
