I want to up my Astra to 200BHP however I don't know what root to take.....
I've no plans to go beyond 200 once its reached so I'm really after the cheapest option out of:
a) SBD TB Kit + all fixtures/extras/fitting
b) Larger 2.0 lump + all fixtures/extras/fitting.
Which one would be most cost effective (Most important), beneficial and reliable?
