You are correct, the LS1 is not much heavier then 13b REW. > [@FS: dsm stuff](https://forums.speedlife.net/t/fs-dsm-stuff/2084/7): > > despite their drawbacks, i think rotors are neat-o! if you wanna do a swap, try an R26B quad rotor. I must agree 100% Rotary engines are marvels of engineering. It would be almost impossible to find a 4 rotor, I believe they only made a few for there famous LeMans car. > [@9-6-05 Anderson's](https://forums.speedlife.net/t/9-6-05-andersons/2071/25): > > “You just need to treat the car like a lady and she’ll do anything to please you… Treat her like a bitch and she’ll be your worst enemy…” > > I still love my Nissan’s but I got a soft spot for the FD’s… 😛 ^+100000, I will always have a soft spot for the FDS3… The little engine that could is what comes to mind first. --- _[View the full topic](https://forums.speedlife.net/t/sr20det-on-an-rx7-fd3s-is-it-possible/134125)._
