lowlyfe Posted May 7, 2013 Share Posted May 7, 2013 Theres a mint 240 shell for sale for 450$ just around the corner from my place and i immediately started scheming. I decided that if i was to buy the shell, id want to build something fairly unique so after flipping through a couple different sites and forums, a 240z powered buy a possible rx7/rx8 rotary would be kinda unheard of. Any thoughs/suggestions? I know it'll take a deep pocket for such a project but would it be worth it? Quote Link to comment Share on other sites More sharing options...
s30zgt Posted May 7, 2013 Share Posted May 7, 2013 (edited) A few people here have done it. plenty of people in japan have done it http://forums.hybridz.org/topic/93583-commonsnapper-3rotor-240z/ http://ameblo.jp/khrono8473/page-2.html#main cool but nothing new.

T-Bone028 Posted May 7, 2013 Share Posted May 7, 2013 If the shell is as mint as you say for $450, buy buy buy!!!! Powerplant scheming can wait until it's safely secured in the garage! Quote Link to comment Share on other sites More sharing options...
Pharaohabq Posted May 7, 2013 Share Posted May 7, 2013 YEah, Especially if it's in great shape. buy it. I'm sure there's not that many S30's left in Canada. Even going back to stock shouldn't be very expensive. As for Rotary, The RX8 13b is a pretty great engine, but you'll eat clutches and you HAVE to use the Mazda tranny, since it's geared for the high RPM of the Rotary. now a 3 or even 4 rotor Rotary would be especially awesome.

pet280 Posted May 13, 2013 Share Posted May 13, 2013 it would be nice and light for sure. could be lots of fun up a 10k rpm. Quote Link to comment Share on other sites More sharing options...
thedarkie Posted May 13, 2013 Share Posted May 13, 2013 (edited) 20B would be incredible.. not sure how costly they are (5k+ no question). The 4-rotor is in another realm altogether, that would be a very expensive build probably. Edited May 13, 2013 by thedarkie Quote Link to comment Share on other sites More sharing options...
DatsunZman04 Posted May 13, 2013 Share Posted May 13, 2013 You can make some power out of a rotary enging, we used one on a smaller pulling tractor and had it run on alchol and turned close 12 thousand easy. We ran it in a light all open class for years. They can be modified for a unique sound and power. I have even seen where a guy modified one to run off of propane. It didnt run run very good but it still worked. They are a clever designed little engines. Quote Link to comment Share on other sites More sharing options...
PLATA Posted May 13, 2013 Share Posted May 13, 2013 (edited) If the shell is as mint as you say for $450, buy buy buy!!!! Powerplant scheming can wait until it's safely secured in the garage!

lowlyfe Posted May 13, 2013 Author Share Posted May 13, 2013 im thinking pretty seriously about this now and have put down-payment on the shell. only thing im still questioning now is would it be possible to get better fuel mileage (this car would be a daily) through ECU tuning or would it be better to just build the car around a fuel stable build? i know rotary engines arnt made to be good on gas but im pretty uncomprimising on the power and weight savings Quote Link to comment Share on other sites More sharing options...
Pharaohabq Posted May 13, 2013 Share Posted May 13, 2013 My old RX7 got decent mileage, BUT it didn't really matter just how I drove it, since I was always in the 5-8K RPM range. Most of the time I was gettign about 20 MPG on a 13B. I've heard that a well running L28 can do 25-28MPG pretty easilly. That's good for a DD. Now if you go with a 4 cyl like the KA24, or the SR20, you can get into the 30's depending on the weight of your foot. Again the Rotary engine, you'll need the tranny from it, because it's geared for higher RPM. A 20B would be great, but it's not cheap to get a hold of. I love the Rotaries, they're a pretty crazy design, but they are limited in a few areas. Biggest issue I've seen are burnt clutches. I'd love to see a hybrid electric powered by rotary. That'd be pretty cool. anyhow... Quote Link to comment Share on other sites More sharing options...

Just something to ponder I wouldn't give a damn about mileage, personally. Throw a mean 20B into that thing and push for a reliable 500whp Quote Link to comment Share on other sites More sharing options...
