As much as the L28et is an easy and affordable swap, not to mention easy torque, it is a very old school engine. I had one in my '71 240 and I loved it. By the way, I don't know were in hell does this guy think that an L28et has more aftermarket support than an SR20det. The L28et was produced for only 3 years and only in a 280zx, were as the SR was produced for over 10 years and used in various forms and sold in the 100's of thousands. Anyhow, im also getting an SR for my 240 since I wanted something that would be lighter, modern, able to rev, and has numerous aftermarket support from various aftermarket companies. I have also found a new love for four cylinder turbo engines since I also own an EVO. It makes 494whp on the stock bottom, head, intake manifold, etc. The only internals changed were the cams and headstuds. This 4g63 is very much like an SR20det in that it has a tremendous following all over the world. They are built very similarly and require minimal parts to make wonderfull power. So I figure that if the 4g63 moves the 3250lb Evo like an animal, then an SR20det making 350whp will make the Z an amazing beast.
