Message and reasoned thusly (as detailed in the ebay ad):

Now, the RB26DETT DID make me think. I would not have considered a lesser Nissan 6 cylinder (RB25, for example) because they are obvious compromises. There is no compromise in this car. But the Z is already nose heavy. Just look at it! I am a driver (actually test drive Porsches for a major magazine and write 10 page articles about them as a side job... you can actually go to a bookstore NOW and buy one in which I wrote the cover story). Having unneeded weight in the nose would only be cool when it was sitting still with the hood up. That's not something that I respect either. I saved some 200-300 pounds (which is more than 10% of the overall weight!) by going with a lighter engine. Don't get me wrong, the RB is a great engine and sounds amazing and looks cool. But it makes no sense to me to have a car drive horribly just to have those other benefits. Whenever I considered that the car couldn't really take more than 500HP without having major chassis work (full cage, for example... which was 100% out of the question), I decided to see what could be done with the lightest engine I could find that met all the other criteria: The Japan-only Nissan Sylvia's SR20DET. When the geniuses at National Speed said that they could easily hit my goals with pump gas, little turbo lag and wonderful torque (see above dyno chart) with the SR20DET, I was sold. Granted, it took a ton of money to do it, but what we have now is a car that has a switch on the side of the center console. With it flipped backward, it puts down roughly 320rwhp and almost that much torque, all while getting over 30mpg on the interstate. Flip it forward and you unleash the full 434rwhp. This switch can be flipped at any time while driving. It's amazing and VERY noticable. Simply wonderful.
