I sense a poll in your immediate future...
B16 FTMFW. A little built B16 with a 10k rev limit, delicious. Dec block, skim head, high comp pistons, H-section rods, cams, rebuild head (maybe a cheeky porting)... Winning. That's what I plan to do to mine, should make around 190-195bhp.
One thing you'll struggle with is gearbox choice. Hyrdo is a must IMO and then you're stuck with Y21 (if you want OEM LSD) which is getting rare as fcuk. Avoid the s9B LSD gearbox, that's what I have. It's great for me in my mini with tiny wheels but the gearing would be way too long on 15" wheels.
