The intercoolers and rads seem to be fine, turbos Ive heard all the web horror stories but not used one myself.

I doubt their 170mph terminal car has the same products as they sell for peanuts though TBH


With regards to the manifolds, I also know someone (white 200sx from london way, forget the guys name I was talking to him down at my workshop monday night) who had an HKS one that kept cracking and has replaced it with a xs power one and it hasnt cracked yet.
