You think a PZ is fast? One of my good friends had one for a few years, wasn't impressed by it at all! It was standard though mind (aren't the ECUs untunable?)
They're meant to be 230bhp aren't they, but apparently most only put out around 185 from memory?
Another friend also owns an S2000 and I would say that's a much faster car. 240ish standard and probably lighter.
I think you should consider using the Clio for sprints, you'll probably be pleasantly surprised.
I f**king love it tbh.VTEC isn't what it's all cracked up to be..
