Ok, so my friend may be buying a 84 GSL-SE, with a blown coolant seal. We're going to look at it tomorrow. Anyway, Im getting a 87 GXL as a parts car, with a good running engine. I just wanted to know if there is anything abnormal or special about swapping the engines that I will need to know?? Will the entire FC wiring harness be needed?? IM assuming the FC ECU will need to be used, but anything else I will need to look out for? I am using the entire FC engine, intake manifolds, everything. Thanks..

Thought the motor mounts on the engines were radically different, between a S3 and S4

Try a search in the FB forums, I think I saw a write up about it.

See Im really not sure, alls that I know is that Ive seen a few people's sigs that have FBs with S4 engines in them. Ill try in the 1st gen section, maybe Ill have more luck there, thanks.

The motor mounts and the front cover are different and I think the oil pan too.

Whatever you do, reinforce your ground wires and add some.

I have a 13bt in my 84 gs and I don't know if some grounds were missing or what, but when I added some, it made a huge difference.

Search for my latest posts, I posted some pics earlier this week on grounding stuff.
