Is There Any Way To Have A Rotary Engineered In A Ke10/ke11?

The 15% relates to the "maximum capacity engine for that car". In other words 15% on top of a 4K. 1300cc + 15% (195cc) = 1495cc

So i guess a 5K would just scrape in.

 

The 12A needs mounts welded to the chassis rails, and its not an option motor for that model of car. So that rule above does not apply.

Structural welding will be required. Its not a Toyota motor, nor is it a bolt in conversion.

There is no way around these issues, thus you will have to go see an engineer.

 

You will have to pass db testing, as well as emmissions testing. I can tell you first hand that you will need a stock standard 12A, with a std Nikki carb, and an air pump. I even resorted to tuning my car to run on E85 fuel to get the HC count down.

Some super restictive mufflers will be needed to quieten it down too.

 

*EDIT*

I can understand you trying to find a loophole in the laws. Trust me, there isnt one. I spent hours reading over the VICROADS website trying to find an easy way through........There isnt one.

My engineer drew up diagrams of how he wanted it fabricated and all the small details that were important like direction of welds on chassis rails etc.

I did it all to within his specs and i still got knocked back on the first inpsection. Your front and rear track will be measured ( i got knocked back on 17mm).

Brake tests...emmissions...db tests....brand new seatbelts.....the list goes on.

 

I can gaurantee you that they will go over your car with a fine toothed comb. So be prepared to spend money, and jump through any hoops that are put infront of you.

The trouble with that is that a 4K wasn't available as an optional motor for those cars. So at best, a 3K with 1166cc is the base, and a 4K scrapes in. (1166 + 175 = 1340cc)

 

Also, I beleive that the RTA goes down to the cc, not on the "thats near enough" principle. So that even if the engine is close to right, but still too big, it still won't pass.

I'd continue reading if I were you. More than likely they use a modifier to calculate engine capacity for Rotaries so that it's not that straightforward.

Its twice the swept volume of all rotors.

Whats the weight of a KE10?

 

Multiply that weight by '3' for a NA engine and thats the max cc's for a replacement engine. Multiply the cars weight by 2.5 for an Inducted motor.

 

A rotary's cc is classed as twice the swept volume of all rotors. So a 12A is 2292cc and a 13b is 1308cc.

 

If its over 2292 then a 12a is possible. I recall the cc of my 12a being recorded as a bit lower on the engineers certificate, so i don't know what figures or info he used.

 

I got knocked back on a 13b in a KE30 in VIC, but a NA 12A passed.

 

I wouldnt even bother with a 10a to be honest. I have seen bugger all blocks and parts for sale lately. Even the production of 12a rotors and housings have ceased. If you need new rotors and housings, you have to buy machined down items from 13b's. Pricey$$$

 

 

Just a question for you "roosa". How does a 12a's swept volume equate bigger than a 13b's?

 

I think it might be a typo. 1292cc sounds better for a 12a

Yep its a typo.

The 1308 for a 13b should be doubled. So it should be 2616cc for the 13B and 2292 for the 12A.

I wasnt trying to really search for loopholes as such - its just something ive always wanted to build, and i'd hate to think that if i spend all that time building it i wouldnt be able to enjoy it by being scared of getting pumped everytime i take it out.. Everything would be done properly in this kind of build let me assure you.. So, disregarding my last post still..

 

my ke10 has 760kg on the rego papers ....

 

Wow really? So id be able to take 2280cc then and get it engineered.

 

If its over 2292 then a 12a is possible. I recall the cc of my 12a being recorded as a bit lower on the engineers certificate, so i don't know what figures or info he used.

 

And 2292 is bloody close to that, so id love to know what the engineer had the figures down as because it may comply with that weight..

 

That comes pretty fckn close as said.. Which seems like a way of being able to get engineered, unless I'm misinterpreting something?

If you spent all that time building the car without getting the initial engineers approval, then yes it may all be a waste. If the engineer approves it, then go ahead and build it.

I keep a laminated copy of the engineers certificate in my car at all times. Not that it will mean much, since all the cars details have been changed on the vicroads database. Including the engine number. So if you ever get pulled over, the engine numbers will match regardless. You will have the engineers report to show first hand that its all legit.

I'd be more concerned about being done for being too low or loud....rather than the obvious engine conversion.

 

I can't stress it enough. Book an appointment now. It may cost you $50 and 30mins of your life, but discussing it on here is getting you nowhere.

This may not help you but i can see 3 reasons not to put a 12a in a 800kg car 1st theyre heavy, 2nd they don't put out much power, 3 cops hate rotories so even when theyre legal they just book you for something else, think out of the square, 2.2l and light, 2L suzuki vitara with a gti head or V6 vitara these come in 2L 2.5L 2.7L and 3L all these motors are very compact, light weight alloy and boxs are easy, i think a ke10 with quad cam 24valve 6cyl would be cool
