Was just wondering about Z2OLET tuning, is there anyother online shops that sell parts apart from courtenay sport or regal?
I think the 1st thing im going to do is upgrade the air filter and pipe work, what seems to be the best set up for 2.0 coupe turbo to gain the most bhp? i've heard something about the 2.2 air box and vectra c intake pipe but not to sure what this is about. or do i go for a performance pannel filter and dbilas 130mm intake pipe, or 50% bigger than standard pipes, or dbilas flowmaster with k&n pannel but its £233 is it realy worth it?
2nd thing is to get a dump valve and a silicone hose kit with a power pipe, what seems to be the best DV for the z20, dont want anything that sounds stupid, just a nice tcshhhhh. I've seen theres two silicone hose kits avalible, a courtenay sport one and the regal one, what seems to be the best one? and will i be better off with a metal power pipe than a silicone one or wont there be a differance?
3rd thing i would like to get is a full s/steel exhaust system, cat-back, pre-cat and sports cat, from what i've seen milltek seem to be the most popular but is it really worth the cash, is there any other decent systems on the market or should i stick to milltek?
hope you can help, cheers
