Totaly depends on spec, and what power you want. if it was a stock 1.6zetec youd wang a pussy T2 on it and watch the saxos still come past, if it was a nitromethane powered 2litre zetec from some 7second american FWD drasgster youd be wanging on a Turbonetics Y2K to give you the 1000+bhp you wanted...

Can go for the normal T3/T34 business off a RST/Cossie as it easy n common, but a GT series will be less laggy for the same power.
