FujiRacing 13B Rotary Miata Build

FujiRacing · 03-08-2010, 05:28 PM

ziig get those pics on here, I like to see your build.

We will be coming out with Semi-PP Intake manifolds.

REDLINE TIME ATTACK Sebring Florida August 14th-15th we hope to be ready by then.

Our KAAZ LSD in on it's way.

We will be using our own FujiRacing 50mm ITB's and Fuel Rail.

Not to threadjack, but it seems like the FD would be a great fit in the street tire class.

A GTUs would be a nice fit in the Enthusiast class as it seems to only restrict forced induction upgrades. You can make the argument that porting is like a camshaft, so you'd run the largest port that still lets you pass emissions.

(Or you just run your car on E85 and drive a bridgeport / p-port to totally annihilate the competition, that should still pass emissions, right?)

I just realized, Corvette's will probably own in the Enthusiast class.

Ever thought about getting these for the Miata build?

Which block are you guys using? There have been good results using the RE block in NA form with either 9.7:1 S5 NA rotors or some special 10.2:1 Rotors that KDRotary had used in an NA 20B build. Methinks they were just 10:1 rotors though.

Our FujiRacing 50mm ITB Throttle Bodies just came in from Japan. It has 2 Injector ports per Throttle. I will post pics the next couple of days.

Patiently waiting for pics... I potentially have a rotary powered endurance mx5 project in my future

ziig · 04-06-2010, 02:33 PM

look at the thread for rotary of the month my miata is on there. I ran 9.7 :1 rotors with the turbo, damaged a rear stationary bearing so i swapped out bearing and decided to drop compression a bit now makeing 310 @ 5 psi

As an owner of a Miata with a blown engine and and ugly FD with a good engine, this is intriguing to me.. cant wait for more info on this kit.

FujiRacing · 04-20-2010, 03:28 PM

Moving along just fine. Car will be ready sometime this year I can promise you that.

Pulled my Mazda Torsen Diff. and the alum. housing was cracked. What's amazing is we were able to set the fastest time (over 85 Miata's) @ Hallet Raceway 1.8 mile circuit on 100 treadwear tires 1:28.2 with our 184 whp N/A ITB Piston motor beating the old time of a Supercharged 260 whp time of 1:28.3. Driver only had 1 session and put down the time with the cracked housing which does affect acceleration and possibly handling. I have a pretty good idea what the piston motor can do and can only imagine what the 13B will do.

Note: Last week testing the 1st gen RX712A Semi-PP in the 1/8th and the R&P Gear broke. We will try again this week.
Semi-PP is not new to us.

Received my Apex Seals from Japan. I need to get the Iron plates and waiting on the XRP fittings for the fuel rail.

cencalballer · 06-27-2010, 05:34 PM

Very cool and excited to see this finished. i would love to have a miata but i hate the 4 banger in them.

djmtsu · 10-22-2010, 09:14 PM

Updates.

Looking into a future Miata/rotary project and would like to see some real information about the swap. Not just bits an pieces of info.

Thanks Fuji!
