12A Posted May 24, 2011 Report Posted May 24, 2011 just thought i would add to this. there is nothing special about a '12A turbo' gearbox. its the same as a NA S4/S5 RX7 gearbox. Quote
BUZ440 Posted May 25, 2011 Report Posted May 25, 2011 For the gearbox to clear the tunnel depends on how you mount the motor, if you mount to the Corolla crossmember might be a bit high, if you get an aluminium crossmember and lug it to the chassis rails with the 12A front timing cover bring it down a bit might be a good angle to clear, there is a shop in VIC that makes these and are engineered at a great price, Leroy is his name, and has that gold gemini with the 350ci in it some food for thought?

jimmy-d Posted May 25, 2011 Report Posted May 25, 2011 National Code of Practice for rotary engines says- Displacement X 2 = swept volume X 2 = allowable engine size So a 12a at 573 x 2 = 1146 x 2 = 2292cc So again it depends on the actual listed weight but under 800kg X 3, 800 to 1100kg X 4 for a n/a engine,both the previous have to be multiplied by 2.5 or 2.75 respectively If a ke30 is accepted at 880kg/ 880 x 4 = 3520cc for n/a for rotary 880 x 2.5 = 2200cc A 12a displaces 2292cc according to code of practice so technically too big/not allowable BUT its up to the Engineer to certify isnt it! This is how I read it anyway and I have referred directly to my copy of the code. Quote
BUZ440 Posted June 1, 2011 Report Posted June 1, 2011 This might help, link to where you can get the crossmember, http://www.btrperformance.com.au/ You will need to measure the distance between the rails and provide it to them, for the price and to get it going can't complain, even ADR approved, I think a certificate comes with it Quote
