hi all, first time using a forum so go easy on me
I have a mk 4 astra cd dtl16v 2l turbo diesel, had it for a couple of years but now wanting to make it a bit better, so far I have put some lexus style rear lights on, some 17 inch alloys with 215 40 17 tyres, a k&n 57i intake cone air filter, have yet t suffer from this dreaded 'heat soak' iv heard of but am thinking of installing a heatshield and cold air intake, but what next ? any suggestions ? was thinking of dropping it 20mls ish but any suggestions would be really useful thinking of an initial budget of £500 but maybe more in the future, cheers all
