Isn't the mk4 rated at mid 13's out of the box? Granted I've never driven or ran one but I've got to imagine with someone who knows how to drive that is not true (especially at 400hp).
None the less yeah the supraforums guys can be dicks. I made the mistake of once agreeing to the common knowledge that the mk3 7m is a piece of shit motor after experiencing a blown head gasket and rod knock in a matter of 36k miles on a car that was bone stock aside from exhaust and intake. Needless to say I got a verbal lashing beyond belief and apparently "people like me are what ruin the supra community" lol. The sad thing was that last line came from a dude whose company produced carbon fiber hoods for the mk3. I was actually looking to buy one from him but now he can go fuck himself.
Ha what would that be like 5 lbs of boost? You could slam the throttle and lag for 3 days.
