I've got a MK4 Astra with the earlier 115bhp 1.8_16v engine ( C18XE1 ??? )
I've got a full s/s cat back exhaust and derestricted my airbox and have a panel filter in there. Recent Rolling Road results have given me 123bhp and 129.7 lbs of torque, which I am happy with since I've only spent £120 on that exhaust second hand and a filter.
Anyway, I want to try and get more power from this car since I'm planning on keeping it another year or so.
Any advice is welcome, I dont want to spend a lot of money, and would love to hit 140bhp from this.
Courteny suggested just getting their cam kit, and that should get me 135 odd over what I have. Does anyone have any experience with these? Also would a maifold be worth it?
