you can do it. but with the loom from the bob its bloody complicated, the pats system can be bypassed but its a wanker to do. i wouldnt want to attempt it. boa is better, with vectra v6 injectors, and get rid of the viscous fan and put a couple of good electric fans in place. it will give you a slight power gain, only slightly though. but i prefer a electric fan than viscous. fab engines though, ive got 2 boa's around 195bhp standard.
