I have been heavily into these cars for about 8 years now. I recently finished swapping in an S13 SR20DET in my current 510. It is the most fun car I have ever driven!! It is extremely powerful (dynoed 228 at the wheels on low boost) and the completed car weighs 2,000 lb even. It tears through the tires in 1st, 2nd, and I usually let off in third because I am going sideways and losing control.
I have not dynoed it at high boost yet, or ran a 1/4 mile.
Coming from the mouthes of sesaoned 510 experts and enthusiests, dont waste your money/time on the L-series swap in a modern engine.
And avoid V8's, they are heavy, and they do not perform as well as a well as a turbo-4. THe SR pulls hard all the way to the 7500 RPM redline.
The rotary swap sucks, sure the engine is light and you can lay it way back in the tunnel, but rotaries are such a nightmare, hardly anyone is doing them anymore. THere are plenty of V6 swap kits available and the SR20 kits are popping up too.
I personally did all the fab work and technical details on my engine swap, and I am very pleased how it turned out. I will try to link to a pic here:
