im kinda split on this one... I'm a big rotard... I'm also a now a big S12 fan... my heart says that id love to see it happen but honestly even though its completely pheasable, i don't know if it would be logical...
if you got the body sorted out(reduced the weight, get a good, non confused suspension under it, and pretty much just balance the car out)It would make a killer track car.. with the rotary's small compact design, it would fit further back and lower in the engine bay, AND on a track, most of the time, your in your higher RPMS anyway, that is where the rotary shines as a performance engine... Rotary engines make all of there power north on the powerband, and they have been proven over and over again, that they can handle overreving and high rpms longer.
As a streetable car? Its doable, thought i cant figure out why youd wana go through the trouble... LSDs and aftermarket for our cars are non-existant (cept for bartco) RX7s have a much more abundant aftermarket and lsd are plentiful... on top of that, i love my s12 as much as anyone on here, but is there anyone here, that could honestly chose an S12 over an FC on looks alone?
I didn't think so...
as a cool factor, ice cold... but honestly with the money spent, id rather set up an FC. NOW if we were talking about that RaceSilvia guy with the red widebody S12 in finland, should he decide to go 13BT or NA 20B, I would just lose it
btw, if you end up doing, congrats and good luck, but imo your wasting your time trying to build an NA motor and 20Bs are about 10k to put into an FC. go 13BT and push "enough" boost, don't go crazy with 500hp or some crazy number... great rotarypowered cars are tuned with the balance of the body, not with the engine... and besides, boost kills rotary engines, but moderate boost with tunning can be reliable
na... if ya realy want some good rotary porn, go to youtube and look up Bridgeported and PeripheralPort NA motors, those are the ones that sound like pissed off chainsaws
and as always, go to RX7Club.com for cool vids, support and lots of flaming
