hmm somehow i dont think "DRS" is actually speaking on behalf of demon rotorsport in NZ. I have heard nothing but good things from customers and as a reputable business i dont think they would be making such outrageous claims. Maybe "DRS" should concentrate on his/her spelling and wording of posts before anyone takes them seriously. Just my two cents

Hmm, would I buy an experimental engine from someone who can't even operate a keyboard? Let's hope he's not really associated with any professional rotary shops...

I have been saving up for a 4 rotor for about a year now and I'm ready to start the project so I spoke to someone at Kiwi-re on Sunday about ordering their 4 rotor kit, which is basically all the "special parts" needed:



The 4 rotor kit has the following:-

1:- Eccentric Shaft

2:- Front counter weight

3:- Rear counter weight

4:- 2 x Centre plates

5:- 2 x Stationary gears (modified)

6:- 2 x Stationary gear carriers

7:- 2 x Stationary gear external oiling mods

8:- Rear main nut

9:- 2 x eccentric shaft end caps

This kit is built with all new parts and also uses genuine Mazda parts.



I was quoted 9500 NZ plus shipping and about a 6 week lead time. The only thing I'm stumbling on is PP housings, which cost about 1750 NZ each...which equals about 1100 us each. Granted they are new housings which arent cheap, but I dont know whether I can have good/used housings p ported state-side for less, and and who can do it https://www.nopistons.com/forums/pub...IR#>/dunno.gif



BTW, I was told that they built the one that is in the red FD in NZ

Call Jeff Bruce at Precision Engineering, NZ 09 4153264. He makes the shaft , modifies the side plates to take stat gears dowels and pp's the rotor housings. Kiwi re just gets the bits and adds there 150% markup.

I spoke to Jeff about a week ago , and there is a US agent that sells the stuff , but i forget who he said it was.

Last time i had housings p ported it was $350 nz each + new housing.

As Nospig said don't go thru Kiwire, deal with Precision Engineering direct and save yourself a lot of $.

On top of the parts listed you'll need long thru bolts and dowels, Precision Eng makes these also.

You'll also need an external oil pump, either wet or dry sump. Those housings are a hideous price, new housings are only about 550nzd each and I charge 400nzd each housing to sleeve and port, inlet & exhaust. If you want pics pm me. I'll be building a 4rotor PP for a customer in the next few months. Kiwi re did not build the 4rotor in the red FD, the owner built it himself. They're good at taking credit for other peoples engines.

I should add that not only did the owner of the red FD build the engine himself, he also did most of the machining with Precision Engineering only finishing the crank and a couple of other bits. He's very talented engineer (in fact they both are) and his is the first really successfull 4rotor engine I know of outside of Mazda. To date the FD has run a 9.9, it runs on pump gas and is untubbed, its also street legal.



Credit where credit is due.

Danomite 05-10-2006 07:53 AM

thanks for the heads-up guys...I have been wondering why the cost has gone from 4500 to 9500 in the last year. I will be calling Jeff this evening!
