First of all, by buying a VG30DETT, I meant the engine with the car it came in wrapped around it, that being the 90-93 300ZXTT right? I hear the 90 model year has problems (ie brake rotor warp), so I'm opting for a 91.
I appreciate the information given, and I did not know that the 90 240 was SOHC. That's why I'm asking, to learn. What are the main differences between a KA engine and an SR engine? Aren't the SR engines a little on the steep side as far as price goes?
Thanks again for the info.
BTW: RB26DETT? Skyline? Sorry, I'm just a Honda guy expanding my horizons.
