Ok so i read this up above in the swaps sticky : http://www.automotiveforums.com/vbulletin/showthread.php?t=19176
Can any one give me some more details on this, trying to find info on swaping the supra pistons talked about in there for a project a buddys working on he's using a b7 block with an ex built head.

Let's say you want something cheap but you could work on for possibly turbo or nitrous? The D16Y8 is cheap and the pistons are the exact size of TT Supra pistons. They could substitute for forged versions and work just as well for a turbo upgrade. Be warned though as the D16Y8 has a particularly bad Rod to Stroke ratio at 1.52. I also suggest the B15B7 which is the 5th gen. Dx and Lx engine pushing 102hp @ 5900 rpm and 98 lb.-ft of torque @ 5000 rpm.
