I have recently acquired a 13b core that I plan to rebuild, I drive a 1986 Mazda 323, I want to put the two together. I know I will have to do lots of custom work to make this happen. Does anyone have any tips on rebuilding, fitting the engine in, and how to set up the drive train?

If you use the GTX rear end in it then you might get it to work.You'll have to make custom tranny and engine mounts tho.Do you plan on using EFI on it?

I thought about putting in the GTX rear end, but what would I do with the existing stock front end? I heard it's possible to fabricate an adaptor that will allow you to use the 13b with the stock 323 tranny and front wheel drive system. Also if all I have is the core of the 13b where should I start with the rebuild? What do you think?

The stock front I'm not too sure about.But one thing is did the engine run fine or is it a dead one.If you endup rebuilding it you might want to consider getting a streetport done to it.You'll have to take apart the engine anyways.Stock mazda apex seals work good just make sure to replace the when you buy the rebuild kit.I never heard of a FWD rotary before but if you can figure a way to mount it to the GTX tranny and transfer case then you could have prolly the first 13b AWD.That would be sweet.

I'm not sure how the engine ran before I got it, as it was a donation to me. My friend asked me if I wanted a 13B core, I said yes, and that was that. When I rebuild it I definetly what to keep performance in mind, I will try to everything I can to get the most power out of the core as possible. As it'll make my car go so fast. When you say streetporting do you mean the same as bridgeporting? Because that's what I was planning on doing. I'm going to replace the apex seals for sure, but where can I find a good performance rebuild kit? People around here don't rep rotary engines, they are all into civics and similar junk.

Civics are as popular as backyards everybody has one.I do mean streetporting as in bridgeporting.There is a Rx7 place in calgary called Rx7 Specialties.Check thru the threads in the Canadian forum theres a few more places mentioned too.So are you going to use it carbed or EFI?

Do you know of any places in Regina that are good with rotary engines, besides the mazda dealership? I talked to a shop in Winnipeg, I think it's called jackson autosport or autoshop or something. When I asked them about the rotary swap they said they wouldn't even touch it. The only engine swap on my car they would do is to swap for the B6T, but that swap is almost bolt-in. So I don't know how good of work they could honestly do. I plan to run the 13B on EFI, because my 323 is already EFI so why would I change that. Do you have any ideas on how to mount the engine? I saw this one guys website and put a 12A into a 1985 323. He used RX-3 engine mounts, he also said that the RX-4 would work if they were slightly modified. But the problem is that his year of 323 is a different bodystyle and I think it is RWD, so he just had to custom fit the tranny mounts and it was all good.

I have heard of those 323's getting converted over becaust the RWD is so much easier to work with.My 13b is a 84,85 model where the mount is on the front.Yours if it's the second gen motor will have a mount on the sides.That should be interesting to make mounts for as I have never taken on such a project myself.The is a swap shop nerby tho.CWS THey do swaps but I don't know about rotary swaps.I think Rx7 specialties is prolly better.If you swap the GTX driveline then it will be easier to mount the engine then because it is like a RWD setup for the engine mounts

Cws is based out of regina which would make it easier for you to talk to them.Good luck. :bigthumg:

If my 323 was a GTX that would make things so much easier. I could just adapt the 13B to the existing RWD, and switch the useless FWD system for the 1rst gen 323 front axle, or something along those lines. But since my 323 is only FWD that poses some problems. I want to just adapt the motor to work with my stock tranny, because I think that will be the most efficient way to do it. Only problem is finding a mechanic that can do that, because I don't think I can. I will talk to CWS, but I have a gut feeling that this swap might be out of their league. CWS probably could mount the engine and do the swap no problem, I just doubt they could do the tranny adaption. i will talk to them though, because they might be able to refer me to someone else. Or maybe I could implant the the rear and front axles off a 1rst gen 323 and just mount the engine with the RX-7 tranny. that;s another option. This swap is begining to sound more and more expensive everyday. But at least I got a good deal on the engine.
