Another 4 rotor build
#26
Yes Kiwi RE done all the research and development,And Precision engineering make the components for them.
However Kiwi RE is no longer and now Warren Overton (the man behind the 4 rotor) has started his own business PULSE PERFORMANCE and is now building them through this business

Well i put the 4 rotor dummy block together this weekend, and test fitted it in the car.
There will be some work needed to get the engine to not hit the stearing rack for instance. Will need to drop it about 2 inches. And will most likely move the engine about 5-6 inches back into the car. I have about 6 inches that i can move it back before the intake runners for the PP ports will hit the firewall.
Here is some fitment pictures of the engine in the "stock" fd location with the stock tranny. I will be ordering a Libertygears modified Tremec TKO 600 dogbox this week to get it fitted on the engine and see how much back i can move the engine to get the gear stick in the correct position

NICE!
Could i do this with two s4 engines?
I'm looking to go the all motor route myself and this simply looks bad ***. I saw the scoot 4 rotor on youtube and about creamed! It sounds better than a gixxer/busa!

From a budget minded end yes you can. Your still gonna spend a **** load of money just to get it running.
Lets see:
$8,000 for the crank kit.
$1000 for 2 good used S4 cores "good rotors and housings and internal seals" ect
$1000-$2000 for custom intake.
$500-$1500 for custom exhaust.
$50-$2000 for custom subframe. That $50.00 is assuming you know how to engineer and weld the frame yourself and just paying for steal.
$1000 for engine balancing of the rotating assembly.
$1500+ for dry sump oil lubrication.
$1500 for PP modification for intake.
$500-$1000 for used carb set-up
or
$2000+ for stand alone ecu.
$500-$1000 for fuel system.
$200-500 for radiator (this doesn't include fabrication to make it fit) $$$$$
$200 for the internal engine soft seals (coolant seals, oil seals) ect
Thats $17,950 for low end estimate using used parts and YOU knowing how to do most of this stuff yourself including install or $23,000 for newer parts and you still doing most yourself. Oh yea all this is only for a NA engine.
If you want a professional to do it, add $50k and more money for each individual part that's needed. Professional shops will get their mark-up from both parts and labor.
You still interested?

My build cost is going to be about 30 000 USD for the 4 rotor. This is with the engine beeing built in england by a person that does this for a living. And buing a Tremec TKO600 dogbox and all the other bit's an pieces.
So im not sure where u get the 50k$ for getting the engine built, fitted and running mate. My price might go up abit, but not more then maybe 5 000 USD more. That's with todays currency prices.

Things are different over here mate. The 50k isn't just to build the engine, it's for a professional shop to do the complete install from start to finish. Pettit Racing in Florida will charge you (back a few years ago) 37k for a complete 20b swap.
#34
And england is not that much cheaper. So im supprised it's that expensive. But i might get a suprize in the cost of the build. But im not expecting a 50k USD total cost of it running and mapped.

4 rotor built for 13b housings/rotors? I was hoping to find a 4-rotor kit that is built from 12a housings/rotors. 12a-based would shorten the length of the block by 40mm (~1.57'')or so, wouldn't it?
#41
Hmm that's strange, cause 99% of the time US labor costs are cheaper then what they are on europe. If u go to a dealer workshop here in norway and want work done on your bmw for instance it will cost u about 200 USD pr hour to have them work on it for u here in norway.

The 23 would not flex as much because of the shorter e shaft too. 4 rotors flex like a mother. Dont forget to add $$$$$ for strengthening the chassis to support the 4 rotor. If you get it all in and done for under 40k you did really good. Most 3 rotor jobs are around 20-30k here in OC Cali.

hehe well we do have the oil and a rich goverment. i think the oil fund is above 2000 billion norwegian kr, wich is about 333.333 billion USD at the moment. This is what the goverment has in the "bank" and no foreign debt at all.
But the taxes are high, gas prices are high 10+ USD a gallon, food is expensiv expect to pay 17 USD for a big mac menu and so on. But we do earn a decent salary if u have a decent jobb. But u get more for your money in the states if u have a above average paycheck.
lt1_rx7
Yes it's a 4 rotor built on 13b parts, so it will be a real 26b Nothing else is good enough u know. The goal is to get as much hp as the R26b that was in the 787b Le Mans car
Sendt the order in on the Libertygears/Tremec TKO 600 Dogbox yesterday as well. Will get that in about 10-12 weeks time. Since i will be shipping it with boat from the US.
The engine parts will be ready to ship in about 6 weeks i hope

Nice work goin on with your 26b Shall be reallly interesting to follow the build up. Next week i will receive a 20B PP engine that i built in Spring 2007 The shortblock was built for TS Motorsport in Skċne Sweden for their Mazda FC Racing car. But the project was never completed Now i am gonna get the final touches to it, and dyno and sell it. It consist of 3, 13B REW housings that has been ported in Japan. D ported intakes and ML Wankeltrim exhaust porting is on it to. It's been balanced and has 2 mm Atkin apex seals with 9:7 cr rotors. The intake is of Australian made with 50 mm butterflies and a serious 3 pipe headers. ECU is probably gonna be the new Vi-Pec V44 stand alone system with quick tune and logging capabilities. The engine is gonna be dyno'ed on a Super flow 901 dyno with Dyno Doctor " DR Ernie" and me in the dyno cell Horsepower? we will see...

You're reference to that cars power the times have change with technology simply put you should be hoping for higher power and torque goals then what that car was said to produce.
#47
The engine builder built a a long block 20b PP mazda belgium that is racing with a RX8. And that engine produced alittle over 470 at the wheels on a Dynapac. With more tuning he said he could get it above 500 at the wheels. So if we say 500 rwhp on a 3 rotor. We would get 666.66rwhp on a 4 rotor at 9000 rpm. But my goal is to get the engine to last an entire summer without opening it up and changing out sideseals and corner seals. So it will be tuned down abit. We might do a max power tune just to see what it can do. But no need to break the engine just because we can. I want it to be safe, and to be able to race it alot.
The car will be taken to the Nürburgring next year. So it needs to be safe
So im happy with 700hp at the crank. And i can guaranti u that a 4 rotor with 700hp is fast as hell.
