Put M3 cams and valve train in it and you have 220hp engine, halfway the difference to an M3. OBD1 conversion intake manifold and will out even more out. If you're doing suspension upgrades anyways you can get something better than M3's oem setup and still be thousands ahead.

The 328's M52 takes boost far better than the M3's S50/S52 and is reliable up to 25psi with stock internals, just needs a 0.140 Cometic head gasket and v2.0 ARP studs. You can make this car a reliable daily driven 500whp yet it's capable of well over 600 stock.

For insurance purposes I'd rather have a 318/325/328 and put a boosted M52 in it with a complete high end suspension set up. Turn the boost down for 300-350whp and you have a mean road course track day play car...500whp with a GT35 and you have a sub 12 second car, 600whp with a GT40 and it's in the 10's on slicks.
