weegee have you seen the guy on turbosport.co.uk who has put a mini cooper supercharger M45 on a vauxhall 2.0XE engine in a mk1 escort. he chopped the existing inlet manifold to stick it on, and even put an intercooler setup on it.

if you done the JRSC you wouldnt need the black box if you got an aftermarket chip, even if you wanted to you couldnt use it cos it will only work on the US focuses.

you will need an aftermarket chip (such as unichip), bigger injectors, and maybe recalibrated maf. the bigger the throttle body the better it will work.

if your gonna run decent boost you will need better engine bay ventilation, and ideally a bigger rad (try from a mondeo V6)

i done a track session the other day and engine bay temps were sky high. i'm on about 7PSI, and now realise i need water injection for future track sessions, cos mine has no intercooler.

also your best off running it on super unleaded.

one of the biggest headaches will be sorting out where all the vacuum pipes go around the inlet manifold etc. i heard that the rover inlet manifold might be a good starting point for putting a mini M45 on a zetec.

i've done a FMIC on my other mondy if you want any ideas for where to mount the IC.

oh and as for �£300 for a supercharger and nitrous on a zetec in the UK, very best of luck but i doubt thats gonna happen!
