rotor fans, gurus

Just bought a mitsi galant colt 1973 and am keen as fuck to stick a rotary into it, have been doing some reading and searching on trade me for engines etc, and I guess it would be good to hear from the peepz that know a little more than me, 12a vs 13b, advantages and disadvantages, and also from starting a conversation what would be the first things to look at getting. I guess any info as to starting a rotary project would be good.

Cheers

heres mine just for interest sakes

Go for the 13b - a hell of a lot more potential thurr. It all depends how far you want to go though?

I had a 12A bridgeport in my Series 1 RX-7, which was great but I doubt very much that they'd allow that sort of exhaust noise these days, meaning you're gonna need the extra capacity of the 13B to go a bit harder. Also if you're wanting to go all-out for power, the housings on the 12A mean intake port size is ultimately quite limited if you want to go the turbo way...

If you don't mind me asking, how old are you? What have you owned in the past? An NA rotary is more than enough for someone under 20, especially in what I *assume* because of age/style is a very light car.

Is it the coupe or the sedan?

Hey chris, nice bro.

Yeah I guess with the noise and shit at the mo, prob not a good idea to go with a 12A bridgeport, so 13b's are more powerful than a 12a.

am 20, and cash at the mo would be an issue. I was also thinking of ease of working on if something goes wrong, someone said 12a were a lot easier to work on, wot u reckon? and terms of running them which would be more thirsty, generally.

Yeah its a coupe 1973, same as this http://www.trademe.co.nz/Trade-Me-Motors/Cars/Mitsubishi/auction-38849865.htm except I got mine for just over 1.

What sort of factors are involved when putting a rotory in, size of engine bay etc, or is pretty much doable on any car, cheers for your help Pfunk.

Basically theres is not much difference between 12a's and 13b's in regards to working on them, the beauty of rotaries is the engines are tiny, me and 2 mates removed a complete 13B out of my mates RX4 no worries at all, 12A's are even lighter, very very easy motors to work on.

I recommend getting a 13b IDA with injection, it will be the most fuel friendly (not saying much for a rotary but you get the idea) and also the most reliable but you'll need a computer to run the injection which will cost more but better in the long run.

A 12A is not worth it unless you are definitely going to port it, A mate of mine has a 323 wagon with a race prepped 12A bridgey and that thing goes fuckin hard but its $5000 for a motor stick with the 13b injection, if you not going to port it at least take it to a Stage 2 like my mate has in his RX4 and you'll be sweet, if you can't afford injection at least get a webber carby and holley pump

ahh you got the 16L
not too many of those round
much like the gtos

Oh yeah, a 13b will be more thirsty but all good if its not ported, anything with a port or enlarged anything will be more thirsty than something thats not

Get a 12a turbo if you can find one from an oldish cosmo. They make good power and are easier to fit than a 13b, and you will avoid reliability and noise issues that you often get with non turbo ported rotors.

how is a turbo easier to fit than a NA? theres lots more to worry about fitting a turbo, an NA is as simple as drop in, bolt up done, especially if its carby intake, way less wiring to do as well.

A stage 2 13b will be more reliable than a 12a turbo

damn thats clean man

not a huge fan of old rota's but that thing looks very nicely done.

well im not much of a rota fan, so if i had this car it would be getting something like a nissan SR20DET or something like taht, but hey good luck and post up some pics when you are finished

It so wouldnt be right with an SR20DET in it
*Imagines an RB26DETT with the power/weight*

I would definately go for the 13B stage2, it will take a bit more saving over the 12A but definately worthit. My mate just got one for his oldschool rx7 and will be fitting it over the summer

10A twin dizzy..that's were its at.

cheers kris

i think you might be confused
t'aint no rota, tis piston powered

What i meant was a 12a turbo will be easier to fit than a 13b turbo....

gotcha yeah bit easier, depends on the engine bay its going into and the room

im a big turbo man, i love the boost and the whistles so i will always try and convince someone that a turbo is the way to go even if NA is more practical (which it often is)!

Im exactly the same way, absolutly love turbo's, nothing better, however there is definitely something to be said for NA rotors, a 13b-PP makes 350BHP if its decent, nothing at all to turn ya nose up at, especially when you consider theres no lag and with the weight of the motor gives a nice power to weight ratio.

Also turbos cost shit loads more but hey, if we cared about price we wouldn't own performance cars

Having said that my personal opinion is anything below 400BHP is pissing in the wind, now you'll get that with a 20b-PP but I'd take the turbo but the motor will be pricey.. A standard 2.5L Skyline block and head will handle 500BHP with no mods hehehe

yeah thats the good thing about nissans, you cant blow them up....
PP rotors are cool but the fact they only last 10000kms and you cant drive them in rush hour puts me off. great race engines though

Oh you can but you have to be a retard... ive seen a RB20 blown up, too much boost, not a bright driver.

know what you mean about the PP, I just like the noise and the power, still better than a J-port though

i had a datsun back in the day, and the engine sure outlasted the body....

heh same as my datsun - couldn't kill it. even after i put it into a grass bank and on it's side - rolled it back on it's wheels, kicked the guard away from the tyre and drove home :>

Don't forget Toyota Corolla's, shit gear boxes (the new autos) but the motors, they last 4 eva.

I broke my datsun soon before the chassis disintegrated

Meant my parents let me buy an RX-7 though

I think it was from doing roll-backs and donuts in the student carpark

as ya do...

I hear that!

what else would you do in a datsun?
