i think 180 bhp would be good going for an na cologne mate, like i said use the type9, if and when it developes a problem change it. I am in the process of putting a turbo 24v cosworth into a sapph, i will be using an mt75 for that as the torque will be in excess of 300lbft. Why not buy an xr4i? it has everything you want, if you wish you can improve on that. Sounds like you need to get a few bits together and go from there. all the best and good luck
