Rotary Racer

Yesterday I started my process to get the information on what I am going to need to do my super N/A motor. Jim over at Racing Beat took a good time out of his day to talk to me so we could figure out what would be the best motor combo (internal parts, and external parts). Today I was looking into what would be the best distributor (with the way of wiring it up). Geoff @ Mazdatrix was great. His e-mail response time is off the hook for a performance/parts shop. I got all the info I needed with a fax of the wiring diagram ($5). Just wanted to say thanks to these two guys for taking there time to help me out getting this process started.

I'm not surprised you were treated well at Racing Beat. They really do have good service.

Mazdatrix on the other hand seems tempermental at times. There is an older guy that always talks to you like your an idiot and then there is a younger guy who spends time on the phone and treats you like a customer not a nuisance. I can somewhat understand having to deal with "newbie" questions (don't we all), but it is a business and the customer should always be respected!

Enough of that. Good luck with the build up!

It is still not 100% as I am still gathering all the specific details. Originally I was just going to do a very large street port on my 6 mort motor. But from what I have seen from everybody else I am just not going to get the power gains that I want. The only motor out there now that I am interested in before I finalize my plans is Flyby116’s judge Ito’s crazy port (but we have yet to hear from him). See my post https://www.rx7club.com/forum/showth...hreadid=143909
I am probably being greedy but I want the big power (not turbo power, but more than 250). Talking with Jim we pondered all the possibilities of the 6 port. I even brought up the idea of a partial brige on the intermediate housing (using a TII housing). He told me that the motors that they had done that with ended up running like crap . So low and behold the way to make the power is to do a bridge port on a 4 port motor. Here are the specs thus far:

- TII core
- Bridge port (normal not J-Port)
- S5 N/A rotors balanced, snap ringed, clearance.
- Hardened stationary gears front and rear.
- Race bearings all the way around.
- Electronic distributor from a 1981-1985.
- Carburetor. Will probably have to go with a Holly because I don’t think even a Webber 48 DCOE will flow enough.
- Header and the usual exhaust goodies
- Light weight flywheel
- 2 piece 2mm apex (possible 1 piece depends on what RPM I want it to go to [10K ])

That is kind of it for now, I also have a wedding to pay for so all this will be taken in stride and over a long period of time.

just keep in mind its hard to cheerfully answer the same questions everyday, they may have a little attitude but mazdatrix is one of the better places to buy from

I agree with you 100%
It's an interesting market, much different than what I do, industrial A/C parts distribution. No homeowners or teenagers .

Love the setup Rotary Racer! You won't have to worry about 5th 6th ports anymore!

A 48 should flow enough air and fuel. Either that a 48 bored to a 51mm would be enough. CJ

I hear you on the NA motor & big power. If this is for a street car, you might also consider doing a 3 rotor NA setup if you want lots of toque & power.

I agree. Racing Beat has good service. I've gone in there a couple times and they actually help you out. They bust out the FSM and start comparing things and give you tips on whatever youre doing.


Mazdatrix has good service as long as that older guy doesnt answer the phone OR help you out over the counter. I'm sure everyone who has dealt with them knows about him Theres another older guy in there who is VERY helpful and patient. Hes the complete opposite of that mean guy

Anyways, both shops are good and I'm glad you got all your questions answered.

For some reason I think that brings my total of the project over budget a bit. My wife to be might get mad at me if I spend that much hehe. "Honey, I am going to post pone our wedding 6 months and import a motor from Japan, OK "

Ryde _Or_Die

Ya she might just a tad If you don't mind me asking, what kind of price did they give you for the motor(not installed)?

I have dealt with both, and, Mazdatrix is down right the best to get a hold of hard to find parts I love em. With that said, they both have moody Sons A Bitches working for them.

I don't know what it is at Racing Beat, but everytime I call for techinal help, they have tried to discourage me form doing what I am doing. (1972 turbo Rx 2) . I just don't get it. It has been done before, It's hard but not impossible. However, when I call Racing Beat helpline I get answers like it is worth more stock, or it is too much trouble to get a TII engine in it.

They do that for insurance/liability reasons since RX2's have the worlds smallest brakes and the worst handling compared to a 7. Yeah, you can turbo anything, amd you already know what you need, a T2 motor and everything else. I think they don't want to be resposible for putting an idea is someones head that can't finish the project completely. And if you can finish it completetly, you don't need Mazdatrix/Racing Beat's help anyway.

Well the only thing I am buying from Racing Beat is the Racing balanced rotors (well probably a little more). I still have to find a core. I am doing the rebuild and porting my self. It's not a big deal. This is not the first rotary I have ever done and not the last .
