    Motor Choice

    Granted its going to be a while and i mean a WHILE before i get to doing a motor swap in my truck and i plan on doing a bit of research before i make my choice but as of now i pretty much had my heart set on a RB26DETT but then i was thinking to myself hmmmm...what about a rotary motor? I am pretty sure there will have to be a lot of fabrication for either of the two motors but i was just wondering what are yalls thoughts

    The only problem with a rotary is the apex rings. There great when they are new, but 100,000 later there done.

    NO, not just the weakest.. They naturally run hot, aren't good for mileage, don't build torque until the higher RPM range just for a few.

    If you're gonna try modding for an engine like that, I think it would be better for you to look at the different V6's or even the alloy V8's like what Toyota has to offer.
    I mean, the pull-its here have several 300zxturbo's just sitting there that NOTHING has been taken off the engines. A OBDI engine ECU, Proven motor, (thier car was probably heavier than our trucks) and so on.

    Heck, I'm dropping a '62, Chevy 283 in my 88 long bed with a 200r4 and a 3.73(?)Toyota rear.
    I should be around 28mpg city with this light truck.
