I'll be watching this with interest. What transmission are you going to use and are you going stand alone?

we had actually wanted to do the 6 speed manual, but honestly its just too much $$/time to hook it up so we are going with the automatic that comes with it and we are going to be using the impala harness as much as we can

Sub'd. 6 Speed would be sweet but I think you're smart to keep as much from the donor car as you can. What is your plan for the cluster and other bcm related hardware?

If I had the time and money that's how I would do it too. Just completely rewire the car with the donor equipment. Cut and split the jbody plugs onto it for things like the tail lights, window motors, etc.

It will be tough to get the impala cluster in the J dash. I've seen people get pretty creative for other swaps like this. My favorite was someone who mounted the factory donor car cluster in the glove box real clean so it was there when he opened it and it satisfied the passlock issues. Then he ran an ipad with the toque app for this regular dash. It sounds ghetto but he really did a clean install and it was a great idea. You could also just do a custom cluster like pj did instead of a tablet.

Definitely watching this. The 6-speed would have been sweet, but you have to modify the bellhousing for the starter, as well as have a custom flywheel made. I've seen a couple of Fiero guys do the LS4/F40 swap, and it's a bear.

For the cluster, if your car is 00+, you may actually be able to get it to work, but if not, I might try something like a Cobalt cluster or something of similar size. The clusters for the larger cars tend to be pretty wide, but the newer CAN bus system seems to be pretty standard as far as the data stream for the clusters, unlike previous communication systems.

Good luck with this, an definitely post plenty of pics.

Run a flywheel generator and an electric water pump then you don't need any pulleys.




On the inside my car looks like a fighter jet.

more progress today. coming along nicely to clean up the bay just to be clear, we're not cutting out the inner fender because theres no reason to, it's not in the way so it's just being covered to look clean.

Looks like there is zero wiggle room in the bay with the engine in there.
