I'm planning on putting a 280zx turbo engine with sds into my 240z this upcomming summer (yeah yeah that was last year's goal too), but I have a few things I dont like about the engine. first of all, the compression is REALLY low, at 7.4:1, i dont even see how the engine could move the car off boost. Second, I love the way my 2.4liter revs, and the higher redline of 7,000. Now Im thinking, I'll have to rebuild this turbo motor anyway, so why not throw the L24 rods and crank with some flat top l28 pistons and make a nice 8:1 compression destroked 2.6 liter motor. The rod/stroke ratio of 1.8:1 is much nicer than the stock 2.8 liter's at 1.63:1, making for longer dwell at TDC, and loading less angular stress on the bearings. Now I'd have a faster revving, higher redline, less stressed motor, but would all that be worth the .2 liters of displacement I'd be giving up. I like the numbers of my destroked turbo, but the displacement may not be worth giving up. What do all you number crunchers think?
