Is that aimed at someone in particular or are you randomly jibbering on in someone else's thread?
Please quantify your idea of a "full overhaul" and "pointless" and perhaps seen as you like pointing out obvious crap you might want to say something about clutches, fuel pumps, injectors, sparkplugs, cooling, compression test, leakdown test and TC's as well. Would a 74mm turbo be any more pointless or a PHRS3 or how about a 4088 or even a 4088R. Do you believe for some reason that a 67mm turbo is more "pointless" than other turbos...ffs.
Potential for what?
I'd like to see you argue the toss on that one with Ian C. .....Ian you are clearly insane and ill informed (by someone!!)
Why are you posting all this in this thread anyway. There are countless threads on the forum about single turbo upgrades - this needn't be a copy and paste of everything from those threads. This guy posted up about single kits - not cams, not ecu's, not reliability....it was an enquiry related to a potential group buy....not a "Please tell me what I need to do to have a decent single equipped car".
