Did somebody say my name? lol
Tightman,
I think you should stick with the RB25DET. I'm about to order the R34 RB25DET through a shop here in Vancouver. This shop has their own head office in Japan. While the motor is being transported, I'm researching other things such as cooling system, suspension, Disc Brakes (which I already have .... Willwood), and differential options such as R200/R230.
