93 into 80 swap
#2
Anything is possible if you throw enough money at it.
I'd use an FC turbo engine though, much more reliable. Not even the third gen guys run the stock twin turbo setup in their FDs for long.

yes. FD engine into 1st gen is by no means reasonable. Only a very few people have managed to pull it off (or even bothered) because it requires a huge amount of planning and custom fab work, and lots of time, effort and money.
For an FC TII engine, all the info is here, just search. Change front cover and oil pan IIRC, and of course your entire fuel system... PITA wiring (but if you have patience it can be done) and a few other little nicknacks. Relatively straightforward and affordable from what I hear.

Stock for stock.....the FD engine is better.Its got better power,tractability and all the best internal stuff.Of course it has its problems,who doesnt know that?But if your gonna/can take on such a project,that would imply that you are going to adress those issues with new parts,upgrades and/or mods.
The TII engine might be older and less supported,but its stock EFI is more conducive to modification,being metered air type.Its simple and easy to understand and can still make plenty of power for a light little first gen.
The 2nd gen engine(especially the S4) has much more in common with the 1st gen engines,so its far easier to mount up.And,as stated there are plenty of people who have done it(myself included),so you can ask away and search for all the info youll ever need.The only real reason to install the FD engine over the FC,is for the "cool" factor.

There is nothing in common with how any of the 3 engines<<mount up>>
FB mount front cover
FC mount centre section
FD mount rear section
FD engine is more commonplace, better engineered, better supported, more durable. There is no reason not to use it.

I would do a cosmo 13B. You can get a JSPEC complete for around 1300.00. More power than the TII. Do a search. many people have done the swap..How much do you want to spend? look at my sig. I did a Turbo swap also

Sorry.......,"common" may have been a bad choice of words......lets say,"retro-fittable, without fabrication"......
The FC engine can easily be adapted to mount in a 1st gen configuration.The front covers and oilpans are all compatible except for mods needed for the S5 OMP.
The FD engine uses a crank trigger ignition,so running a 1st gen front cover is out of the question.And if you cant run a 1st gen front cover,then you cant run a 1st gen oilpan......and that pretty much eliminates mounting the engine all together,unless you change crossmembers and suspension to FC stuff.

Its not that bad of a swap to do, here is a rough write up of what I did. https://www.rx7club.com/1st-gen-archive-71/engine-13b-rew-1st-gen-write-up-499454/

eveerything would require some type of fabrication. There are some huge threads here that would take you months to read (I know from experience). I was going to go 13bt route (turbo II) but decided against it at the last minute b/c I am not good with wiring...I dont trust myself enough.
IF I could afford it, and I had the electrical knowledge needed to install an FD wiring harness, ecu, wire it all up into the FB panel, than yeah, I would do it. Because the FD is the newest Rx-7 engine available it has the most parts availability, and it does have the heavist duty components of all the engines.
Do your research and then decide for yourself, either way You will have fun, Good Luck!

The FD engine has numerous improvements and better support--my local shop had a policy to not even work on pre-FDs.
It always seemed like a no-brainer to me. If going to the effort of swapping engines why not use the latest and greatest? Considering that one could buy factoy reman (or even recently brand new) FD engines for only ~$2800, why choose a tired S4 or S5 core that would need rebuild (and perhaps new components) anyway? Why expend effort on a stock ECU that wasn't that great to begin with?
If one must--for whatever reason--use the stock ECU, existing wiring, and retain all emissions controls, that would be a consideration. My preference is starting from the beginning, tabula rasa, which IMHO is easier, but YMMV. Everyone has his or her own unique situation, and obviously makes different choices. By the way you actually can use an eccentric shaft-triggered ignition with a pre-FD 13B or even 12A.

Not always an option in our smog controlled little world.
My way of approaching the swap satisfied past,current and foreseable future CA smog regulations in my area.I can go fast,be clean and not have any hassel from the smog reffs or authorities.
And its a safe bet that those regulations will soon be in place across most of the country.CA standards are already the norm in most populous states. Lotsa' good a fancy standalone will do you in 3-4 years when you have to rip it all out just to get your tags! I choose to make the system my friend,rather than fight it.If that means I have to settle for 300hp rather than 400+.....so be it.Probably a good thing for my car and me,in the long run.
