The engine and gearbox were the only bits about my FN2 that really impressed (once I got past the toys and the spaceship looks and racey seats), an absolute work of art, didnt sound quite as good as I expected but its a lot more muted/refined in the newer car compared to the raw EP3.
Steering was better with the FN2 though, when compared with the EP3 that I briefly drove, but still not much feel, and it felt a bit lardy in the corners. Miles better with FRSU and Mugen suspension though, like a totally different car, it was pretty ace then, but out of the box the handling didn't impress. Never drove an EP3 hard enough to really comment and it wasn't a standard one that I had a spin in either.
If I could get a Honda VTEC engine into my current car I think I'd be in heaven be in a Honda S2000...!
