| Post subject: | conversion questions |
G'day Im thinking of doing a 12a rotary conversion to a clubman van , i know i can use a gearbox from a fwd mazda 626 , but after that it gets a bit confusing. what drive shafts do i use? mini or mazda ?etc.. Or do you get them made to suit ? And do you use longer diff ratio to suit the 10 inch tyre ? Sorry if this question has been asked before but i couldnt find any info on this sort of thing listed in the other conversion threads. any information would be great help CHEERS |

I have heard of them but never seen one, or met somone who made one - thought they were just stories. Would love to see some pics and get some info on a conversion. Anyone got any details on the Ford OHC 1600cc conversion - Visard menions them in his book - anyone got one or know anything about them? |

Generally most people either get custom billet shafts made up or as I did take the donor vehicles shafts and get them shortened and resplined, not a huge deal for a decent fabricator/turner. Should be interesting conversion good luck... Cheers Matt |

No engine conversion i've seen required the fitment of a taller diff ratio. You won't upset too many people asking questions about rotars. Doesn't come up often. Do you know rotaries are a tax on people who are bad at Maths? |

Yea, i thought this conversion would be something a little bit different as ive only seen 1 fwd rotary so far . that was built by a guy in NZ who used a mid 90s 626 wagon , so it was quite simple as the 626 bellhousing and the rotary have the same bolt pattern. I did consider making it rwd but decided against it because would have to remake most of the floor pan , subframes etc... With the diff ratios though, i assumed a diff geared to run 13 or 14inch tyres would be effected by running 10s as the diameter is smaller and there for lowers your ratio Or do you run a bigger tyre on the front?? |

Before you start you should look into the maximum size engine that you are allowed to fit into a Mini and then look at the capacity of the rotary. (clue, a 12A is not really 1200cc like a lot of people think.) Mazda did built front wheel drive cars with rotary engines, they also built buses with rotary engines, which proved that Mazda can get it wrong sometimes! |

Yea , but the mazda spec charts and handbooks all specify a 12a as 1.2 ltr and 13b as1.3ltr ? or do the road authorities class these another way due to having 3 firing faces in 1 cylinder ??? |

13B is classified as being a 2600cc,,, not sure what they see a 12A as tho,,, i`m no rotor head but i like them alot,,, actually just helped a mate of mine buy a turbo RX7 with 420odd hp,,, very quick car indeed

As taken from the NCOP --- "...The engine capacity to be used for rotary engines is twice the swept volume of all rotors (eg a 13B rotary engine has a swept volume of 1308 cc giving a 'capacity' of 2616 cc)." |

"...The engine capacity to be used for rotary engines is twice the swept volume of all rotors (eg a 13B rotary engine has a swept volume of 1308 cc giving a 'capacity' of 2616 cc)." Depending on the actual capacity of a 10A you may get away with one of those, but find a decent 10A now days. Didn't Norton make a Rotary bike engine???
