IMO fuck it off and fit a single standard cossie intercooler in a front mount position instead. More effective and less grief to fit.

You can infact (with good results as ive done it twice on mates cars) fit a std cossie cooler to simply replace the std intercooler and the std main boost pipe, so it just sits along the front of the engine bay.
Sits v.close to the bonnet (and dented a mates in the end ) but is v.effective
