The JUN TT flywheel's have step's in them just like stock... I just got one resurfaced today. The problem is that most people take them to machine shops to be resurfaced and the machine shop resurfaces them flat. Also there is no such thing as a "new engine" from Nissan... Nissan's "new engine's" are really just rebuilds... why do you think they have a core charge? And yes they are $6K for a genuine Nissan rebuilt engine... but Nissan doesn't do the work...they just send them to ATK and then mark up the price. Now as far as extrude honing... have you seen how think the Z's intake plenum (upper and lower) are? There's no way they could damage them... I'd like to see this guy remove injectors w/ the plenum in place... oh yeah... he thinks extrude honing the inside of the plenum isn't good but he'll have to dremel the shit out of the outside of it to pull all 6 injectors w/ it in place. Then he's recommending a T3/T4 turbo? A single turbo conversion? If so he's a moron for recommending a V6 engine should use a SINGLE turbo... and if he means twin T3/T4's then he's still a moron cause the lag will be so bad that it won't be streetable... maybe for a *pure drag race car* He's never seen a Z w/ no cats pass emmissions testing without any tricks? Then he's never seen 2 out of my 4 Z's that I've had... no cats, no tricks, and no problems. I passed on the frist try and the numbers were excellent...like a brand new car.
