Has anyone researched, attempted or completed this swap? I keep hearing that the motors (L24/RB25DET) are distantly related (same bore centers, for instance). So I would think that the motor/trans would swap with a minimum of effort - likely the same mounts, possibly requiring a custom tranny mount. Considering that it's a carb'd car, the wiring would be minimal - just find a place to mount the ECU and run the harness - pretty simple, compared with later cars.

This setup would be a killer one - 250+hp stock in a 2300-2400lb car, with a redline of 8500rpm and a matched five speed gearbox. I am really considering doing this swap, so if anyone can fill me in on if it's been done before and any other considerations, I'd really appreciate it.

Thanks

Done quite a few times, use the search function on this site and also try hybridz.org.

basics you will need are custom made:

engine mounts

oil sump

gearbox mount

tail shaft

you should also make sure the chassis is stiff enough and you have the suspension and brake hardware to match the power plant.
