Wow!! 435 HP na!! that would be great, I was only looking for anything over about 300 HP. Luckily I am only going to be trying to push about 1600LB car so I don't need big HP. I went to the motec website and looked around, I think that their new entry level M84 would do a fine job but does alot more than what I am looking for.

I wonder if it is possible to run a 20b with some MSD boxes? I was thinking of calling them to see what they have to say, if for no other reason than to see if they even have a clue what a 20b is. I have run into this with all but one intake manifold maker, the rest of them had never even heard of a 20b, but they all made intakes for 13b's.

Yep, called MSD today and just as I thought, they have never even heard of a Mazda 20b or a Cosmo. Maybe I just need to stick to my original plan using a distributer and just figure out how to do a direct fire ignition like I have on my 13b. Nothing is echted in stone as of yet, so I will keep looking.

Well, just let me know. If you don't already have a connection, I can probably help you out on some of the parts and prices.



After seeing / hearing the NA 20b from DA, I'm heavily leaning towards that direction. I don't plan on doing the full 435 either but somewhere around his first take at 350ish. I think he said he got up to 365 w/o the peripheral porting... Nasty, nasty car...

Hey Justin! Yessir I need all the help that I can get. Now, what are your plans? Are you putting a 20b in that 93 Rx-7? I know that there are some guys that think that I am nuts for not putting on a Big Turbo and Full blown EMS on a 20b. Well, I am skeptical of my own ability to tune a ems from scratch. Besides that I think that when you raise the hood and there are three sidedraft webbers on what I consider a fairly exotic powerplant has certain amount of just plain "cool". Of course three big ole itb's would be pretty cool too. The only 20b other than mine, that I have seen was set up with three itb's. That was GreyGT-C's car this past summer. He also has a Big Ole Turbo under the hood too!

I will go back and forth quite a bit, I'm sure. I'm torn between the wow factor of a 7-800 HP dyno queen (keep in mind this is an advertisement car for my business) and a 3-400 hp N/A road monster.



The current plan is an N/A 20b with an ITB box, street port, doing in the mid 300s. I think that will be plenty rowdy for what I'm trying to do and should keep it manageable enough to still AutoX it! We will see though.. The money won't be in until around March.. All my money is tied up into going to SEMA next month right now! Ha!



I don't think I could do the carb route.. It would be interesting to say the least!

Well it looks like you must be in some kind of car business? If so I can understand your delima, showpeice or driver. There should be a happy median in there somewhere that won't break the bank. Like most people I have to stick to some kind of budget as I have two kids still in college, but I am moving along at a comfortable pace. My engine builder has the engine and is working the rebuild with high compression rotors. I am working on the car itself and thats moving along. The last thing to nail down is the ignition. Worst case is distributer, best case ??? Intake and carbs, the company that is making the intake just needs the go ahead to get started, the carbs can be here in a few days. So if things go well I should have a street legal car by next spring. LOL

Nice! Slow and steady is the way to do it. Spring is not far away at all!!



Yeah I am the co-owner of Endurance Motorsports. We're just really getting into the rotary world (specialization is Nissan but we have close to 30k parts) so I'm absorbing all I can!! Ha!



After talking with Defined Autoworks and hearing their 20b N/A monster I am heavily leaning towards the N/A build with the older (88-93 I think) rotors for higher compression, upgraded apex seals, street port and the ITB box. I think I'd be quite happy with a 350hp N/A show car that I can take to Auto X and the occasional road course! I'll likely run a Haltech ECU to run it all or a custom PC Win 7 set-up like our 350z part sponsor car.. Thing is nuts!



My business partner is building a full race S13 that is going to be pretty ridiculous and we have some very nice show cars that we partial sponsor so I want the hybrid!! HA! I want a full-race car but I also want something I can drive to shows.. I'll build a trailer queen later down the road. ;-)

Well Justin it looks like we are both on about the page as far as the way we are looking at our builds, with mine just being a little more ole school than yours. I talked with Logan at Defined Autoworks today, he was very helpful. Looks like they are going to make a intake manifold for my project, so it looks like I need to get busy and find 3 webbers to go on it. You know it might be intresting to compare notes along the way and see how the final outcome shakes out in the end.

You are definitely going to be a little ahead of schedule on me! I am going to be responsible this bonus season and pay off another large chunk of debt..Ha. I do plan to pick up a motor before too awful long and start wrenching on it but I need to do a few aesthetics to be ready for the show circuit next year as we plan to try and actually have booths / tents at some shows for advertising.



I will likely start a build thread before too long but the 20b is probably still another year out, unfortunately... :-/ I'll keep an eye one what you have going on, though! Always interested to see how it pans out.



If I had Weber I'd be happy to hook you up on a discount but I only have Edelbrock for something like that. I don't have many carb manufacturers...
