i'm not sure which m3 motor he swapped in there, he's a high roller so i wouldn't discount the e46.
yeah the e30 M3s around here are super super expensive. i'd be just fine with a 328is and run it in DSP.
That's correct, the 318is will enjoy a noticeable weight advantage over an E36 M3. Typically it's in the realm of 150-200lbs lighter, but depends on factory options. If the car has an S54 out of an E46 it will have individual throttle bodies, otherwise it's an S50/S52.
