It's not going to be a turbo engine! Staying N/A

I'm heavily against N/A zetec tuning given the small torque gains unles you spend mega money... but I managed to buy my mates car at a silly low price, which had a mega 1.8 on this throttle body kit!

Basic spec:

Forged pistons, 11:1CR
Shotpeened rods
Balanced crank
Aluminium flywheel
Well ported head, with solid lifters and uprated valve springs
Rev limit in the region of 7600rpm

Had a thought earlier; what size are bike carbs / bodies? Haven't heard problems with them maxxing out at high revs!?
