I have no idea what im going to do to my 1200 ute. I thought of so many things and usually my dad is a great help with everything, but he hates rotors with a passion so i cant ask him the good and bad points of them cos he just throws at me "They are s%$t, their noisey and they dont last long". So was wondering if u guys can help me out and tell me the good and bad sides of owning a rotary engine.

Also what rotor would be perfect for a 1200 ute.

Thanks in advance.

Well I love rotor's!!!!! but I do think that they should stay in a mazda. My family has owned about 5 of them from rx2's 3's and a 4. If you warm it up and warm it down then it should rev all day if it is build right and last a hell of a long time. If you look after it, it will look after you!

Your old man sounds like a good bloke. Many of us feel the same about rotaries.

I think you should read about registration laws first. I think you'll find in NSW it's difficult to register a 13B (can only just get away with a non-turbo 12A), in a 1200.

s%$t, noisy, don't last "too" long, and go through sooo much petrol.

I used to know a guy with a bridgeport 13B and a 48IDA weber. It used to use 35 litres to go from Bankstown to North Sydney/return. That's about a whopping 70L/100kms

A standard carby rotary has about the same economy as a V8, and the new re-genesis engines in the new RX8 get pretty good economy.

Seriously, if you can wait and save up to do it properly, it'll better. Doing "rolling upgrades" is an expensive option.

I used to like rotaries...until I found out how much petrol they use.

Cheers,
Chris

Yeah thats what I though as we were going down the road at 160 kph + LOL, then he when out and rolled a couple of them just as I was getting old enough to drive!!!! I though barstard!!!!!!!

A rotor A ROTOR!!! you dont say that word around datsuns.. i told u that... they belong in a mazdas so we can eat them in our datsuns rotors are cool but not cool in datsuns... be wise and get an L20 or a CA the fuel u will save will pay 4 a new datsun .. or 2

Man, I've heard lots of noisy Datsun engines. Likewise, Mazda rotaries are quiet if they have a quiet muffler on them, and noisy if they don't.

Fuel economy? Sure, if you get the power of a V8, you also get the economy of a V8. If you get the 69 HP power of an A12, you get the economy of an econobox. Take your pick.

Don't last a long time? Neither do A12s and A14s if they are revved hard all the time. Depends on how you treat them.

Do what you want. But if your dad and friends won't help build the car, then it's not much fun.

Me? I'm sticking with A-series engine.

you need to make sure you run top quality oil in a rotor, and change your filters every 5000klms religiously. if you keep it under 3000rpm while it's cold, and don't take it past the designated rev-limit, then a rotor will see you into the 200-250thou range - just like any other engine.

couldn't have put it better myself...

if you decide to do the rotor swap, you'll never look back.

i didn't...

my mate had a 1200 sedan with a rotor in it, it wasnt all that bad on petrol unless your revving the hell out of it all the time, i dont like the idea of rotors in dats much either, id much rather a worked L's series or ca. stick with nissan. also his was an aspo 12a and he couldnt get it engineered anywhere cos they suppodely classify rotors as double wat they are or something like that. 12a being classified as a 2.4, thats what i was told anyway. also his seals were stuffed as is the case in alot of them, he couldnt rev it above about 5000rpm or it would bellow smoke. not much point in having a rotor if you cant rev it huh hahah.

I can't think of a better motor to put in a 1200

I have a 13BT in mine which is engineered to avoid hassles. Built properly and tuned by people who know what they are doing so that it will last for ages.

Its stories like these that give rotaries a bad name, people expect them to rev to 10000rpm and live forever without undertaking basic maintenance or preparation when building the motors.

Fuel economy can often depends on the tune the engine has, mine is tuned rich due to the fact it doesn't run a FMIC. However when you are making 300-odd kw at the engine, you cannot expect the fuel economy of an Excel

The best part is that after a bit of a thrashing it will pull up at the lights and purr like a kitten, rather than make noisy piston engine sounds

maybe my mate got told the wrong thing or somethin, i heard they classified rotors as double the claimed output???
