So what do you guys think ?

The main reason i think it would be good is because its physical size is pretty small and leaves plenty of room to work :D

(ive only seen rotary engines in pictures and they look pretty small to me so correct me if im wrong)

wouldn't you need to convert the car to RWD so that the grenade will fit?

I dont but just wanna know if its possible to have a rotary in a fwd car lol.

There was a early model civic with a 12A rotory in it mated to a celica FWD gearbox. It was doing the rounds on the net earlier this year.

would love to see a 20B powered 1st gen, haha would be crazy if it got any traction at all.

Let me get this right:

1> You have never seen a rotary in real life
2> If yes, you have never driven a rotary vehicle

THEN WHY DO YOU WANT TO PUT ONE IN A MAGNA?

I'm not against it or anything, but there are better ways of making friends.

It would not be the cheapest thing to do, you'll have to get a strong gearbox and have an adapter plate made up.

You have to think of how ur gonna mount the thing, it's tiny compared to ur astron remember so that's gonna be a problem.

If you do it make sure it's a 13B turbo it will be something crazy then

@ Magna yeah i have never seen or driven one but i have read about them n **** and know they are a very good engine.

I was just thinking it would be easier to drop in a smaller engine because you can stuff around more lol ( easier for mounting etc )

Tell us about your latest modification, give us all some ideas!

Dont plan to do it, just thought id bring up the idea.

@ Sports, Damn i forgot about the gearbox needing to be stronger lol I just thought a better clutch would have done it but i see your point.

Would be a cool conversion though..

:bowrofl: :bowrofl: very good engine lol
Sorry I don't think you've heard the entire story. Sure, they put out a decent power per litre, but they need very regular servicing, drink through the fuel and need to be rebuilt a lot earlier than a piston engine.

Why worry about a stronger gearbox? Mazda didn't, when they built the series 1,2,3 and four rx7.

The rotory was an unreal engine, but made revs, more than it made power. don't think you'd have tonnes of go, just because an RX does.
Look at the weight of an RX...not much to 'em! If you want to go with a 20B, you're looking at big bucks, plus an extra rotor (which negates the size argument). You'd be better of finding a V8 from a late model cadi (FWD). Have fun anyway, but feel free to toss some of that cash my way........ sounds like you're about to start throwing it away!

nah it was just a stupid brain fart idea i had.

I have alot of stupid ideas :think: I should just stop.

my mates brother has one in a 929 (13B) faily stock. and is his words " i raced a new SS, was about the same in first, wish i had an LSD, 2nd was about a car length or 2 and 3rd well it wasn't worth my time was pulling away very quickly"

also my mate had a drive said it was very fast, and he came from a 4WD bulebird so not like he was used to slow cars

Have u ever owned a rotary? doesnt sound like it.
regular servicing consists of an oil change every 5,000km's, most people here would be doing that anyway....
Yes your absolutely right, they do need to be rebuilt more often than a piston engine, (probably about every 130-150,000kms), but a rotary engine has only 7 moving parts so its alot cheaper and easier to do. hmmm how many moving parts are in your rocker covers.... You can have a full engine rebuild with some port-work for about $1300 - $1500.
Hmm how much does it cost to get a timing belt changed in a magna... $800-$900?!? depending who does it....
i know i'd rather spend the extra $600 and have a BRAND NEW motor every 150,000kms.
As far as fuel consumption goes, city driving u'll get about 12l/100kms.

People are quick to judge rotaries by how reliable an 8second drag rotary is.

just for intrest sack GTR 700 an 8 second GTR has to be rebuilt every 8 mins of running. i think its pushing 1300hp still at 2.6L

Well I'm just going on what my 2 mate's rotaries have been. Both of them were expensive to run and a lot less reliable than any piston engine that I have had. So I'm basing what I said on the previous experience of my mates.

it will also depend on the build of them. my mate just spent $13000 puttin a 12a in his cappella and it makes 176hp at the wheels completly NA and it will last alot longer then any of the other rotar's

^^^agreed

if ppl let rotaries warm up for 5 minutes b4 driving and cool down after driving they would last alot longer, but most ppl who drive them wanna be racers who think they are trying to race the Akina speed stars .. pfft

rotars can be reliable if treated right.... but they r no toyata camry neither.

any engine thats peak power and peak torque are at the exact same point and at the top of the rev range must be kool!

theres a reason why you dont see magna's in fast fours ect

I told myself i wasnt going to get involved in this but hey, here it goes

1.) I have had expiriance working on and with roteries (13B's ) for Drift work in a RX7series5
and yes they are fast and can be quite nice to drive,

2.) nothing on your front end is going to remain close to stock if your going to go the rotery
you will require a FWD 13b halfcut, a s**t load of custom fabrications for the crossmember engine mounts, CV-Joints, antilift kits, clutch, gearbox, steering arm, and a lot more just to get you started, not to mention the headache of per-injectior oil lines, return lines for your fule tank if you run EFI, custom fabrication for the radiator, thermofan, and the worlds biggest headache of an ECU loom and tune you will ever see, if i was you id take half the money this waste of time would cost and just by an RX7, and once you have replaced your 2nd apex seal in 5 months and shelled out for another replacement roter not to mention the brake upgrade and enginerring cert you could have paid for a reletivly nice (insert your dream car here) and still had money to fule it, :bowrofl:

dont bother giving the spelling s**t im over it
