yes I did a tt conversion on my z32 by myself. Most of the z33 is quite a bit easier to work on. Mine's a little harder since it has the tt kit so the sides of the engine is a little cramped but the front and back have so much room and you have a much smaller plenum. Biggest problem i've had so far is that jackass that installed the exhaust used like 3 different types of bolts and the top bolt is almost impossible to get to.
