Hiya,
Any info on whether I should put a rotary turbo or a CA18det in my 1200 coupe and how to go about this
would be greatly appreciated.
P.S Im from australia, (Right hand drive)

thanx

Hi,
No turbo rotary conversion would be legal in NSW. 1200s are limited to about 2.3 non-turbo and 1.85 turbo. The rotarys capacity is doubled, for capacity
in the RTA's formulas.
Go for the CA18DET, Andrews coupe does 12's and I'm sure gets 8-10L/100km on highway.
I run a CA18DET sedan, but I'm not getting the same 1/4 mile figures. But it still goes well.
Depends how often you drive it, as to how wild you make it.

just a thought, maybe you could put a 10a rotor in it and work the crap out of it like a peripheral port, although it would be a crap on the roads ,as you can possably imagine or iguess
a bridge or monster port ,or atleast for in traffic extended port ,that with fuelinjection and mabee even a hidden nitrus bottle could be a weapon, as for strenth theres some nice strong
light aftermarket parts (rotors ,housings etc) if you look for them , ithink MAZTEC had some cool stuff........ so mabee you dont have to turbo/supercharge? mabee you do , but i guess we
can all dream..... but while we are at it a perpheral port 20b with forced induction and nitrous 4 me .....please. see ya in space guys!!!!!!

To save yourself any hassles, ring the RTA in your state, and get an application to modify motor vehicle, then go down to the trusted mechanic that will do the job, they can help
fill the form out and should have a good idea of what you need to do....in re to brakes, suspension, etc. The RTA can then pre-approve it all in advance, and you won't have to waste
extra money.

As for a rotor or ca18det, in WA you can install a 12at easily, shoehorn in a 13b (or ca18det) with enginering as they are considered as 1.2 and 1.3L...(???).

Rotor motors guzzle gas like an 8, and make lots of noise. But they are light, have lots of torque, and rev so easily..

One consideration is that a high HP engine needs to be prepared properly, you can get approx 250 bhp from the ca and 12a, and I've seen up to 320-450 bhp from the 13b.

I was considering one myself, but there are only two rotor mechanics in state, and I won't have a clue on taking one apart, so I am now swaying towards the CA18det.

And after going for a spin in CA18det mans datto, wow what a rush..!!

Hey guys,
As an owner of both a rotang 1200 coupe and a piston powered 1200 coupe my advice would be to go for the CA option for the street as the advantage is torque. The rotaries thrive on revs which
means big speed which does'nt go down well on the street. My racecar has a PP 12A and is a rocketship but is slow out of the corners compared to a a torquey A series. Years ago I ran a PP 10A
to run in the sub 2 litre class. My teammate ran a 140hp 1290cc in his 2 dr sedan. In a heads up drag race (strictly legal officer)the 1290 blew me away off the line every time despite me
having 215 HP. It would take almost the entire 1/4 mile to reel him in. It's not just Horsepower that builds fast cars, you need the pulling power ..Torque as well. We had a CA1600 engined
coupe a few years ago(it was written off in a huge crash) the head on that after a little tickling flowed 240HP and with some cams and larger valves proved to be a super strong performer and
a very worthy replacement for the classic A series. Rotarys are a cool motor but a better on the track where you can throw them into a superlight car and fly. My current coupe weighs 570kg
and it's engine pumps 294hp with EFI. It will accellerate to 140mph in around 500m but it's motor despite all the latest electronics would be a pain in the arse on the street, without even
getting into the already mentioned noise subject. Anyway thats my 5 cents worth, hope it helps.....
