Go for ported headers to combat the lagginess of the 05/20g on a 2 litre engine.

Im hearing good things about GT headers and Harvey Smith uppipes, His up pipes are rumoured to spool 300RPM quicker and give more mid range torque than the ones supplied by GT, will probably go this way myself sometime soon

i can confirm the harvey up-pipes make a world of difference i am running one on my classic with gt spec headers.

quicker spool, more mid range and much more punch from the turbo.
