could anyone on the site that knows of any Aus companys that do a rotary crate motor post a link please

mate i might be wrong but i think there is no such thing

 

there is old stock that has been rebuilt but no new engines if that is what you are looking for

I've never heard of Rotary Crate Motors. I could be wrong in saying, but there isnt the demand for prebuilt motors of this nature. I know when i got my BP built, I went to a workshop of my choice to get it done. You can always go to an importer or workshop to get a low km's import motor.

I think Atkins Rotary may do changeover motors and they organise the freight etc.

Closest you will probably get to a 'crate' rotor and for a few extra k, you can have a performance package upgrade.

when i was working in a rotary shop we did a lot of "crate motors" they were just rebuilt 12a 13b bare block with your pick of port jobs . howeva the shop is closedown now but mazfix and dyson do very good drivein-out packages i just sent my mate down with a blow s5 in was home 1 week later for $3700inc gst . also try ausrotary.com

Dyson is no longer.

I'm sure Mazda will sell you a new engine just like any other manufacturer, it will just be expensive and you will have to buy a domestically delivered rotary, such as an RX8 13B-MSP.

 

I'm sure the bang for buck is better from a Cosmo halfcut or the like...

Might aswell throw a 5k in it, the MSP is a very economically built rotor and porting is a totally different setup, it takes more to get power out of one then what it does a S4/5 engine.

Only because you can just wind the boost up in the RX7. Just the same story as any NA vs Turbo motor. RX8 motors have side exhaust ports as well as intake ports if you didn't know. Pretty much totally elliminates overlap. It'll be interesting when there's a few more RX8's out of warentee and people start tuning the NA renesis a bit more. Already seen a couple of renesis converted gen 1's.

 

Oh and btw, I would personally steer clear of a 12a as Mazda has now stops production of 12a parts, so things like rotor housings are getting rarer and more expensive. You can cut down 13b housing but thats just more expense in machining. Better off just going 13b to start with.

But if you can't go 13B (legally), it seems like the only option for 12A owners. I think Kangaroosa's KE30 is using machined down 13B housings.

Yup, worst case they'll set you back $700 a pair supplied and machined.

A pair or each? And are you talking new or second hand?

A Pair. Mine were second hand, but they were in near perfect condition.

The hazing on them is just some oil.

Was gunna say! Think I paid around $700 EACH for brand new housing when I rebuilt mine a few years back. And they didn't require machining.

Ha I was wondering if anyone else has priced a geni rx8 motor? My mate who is a service manager at our local Mazda dealer got a wholesale price through his spares

dept. How does $10,000 sound for a new rx8 eng and again is a wholesale price that don't include fitting or hang ons etc.

Who said rotary performance was cheap?
