Hey guys, I'll just start off with a few pics and details of the cars: as I promised.
1984 Mazda RX-7 GS
1.1L 12a carburetor engine
Stock engine, trans, rear end
Complete burgundy interior
1987 Mazda RX-7 Turbo II
1.3L 13b turbo engine
Interior partly gutted but should be complete
I plan on swapping the TII 13bt engine and TII trans out of the 87 into my 84, along with all of the wiring and necessary parts.
I will be posting up all of my links that have helped me in this post, then quoting a member's post that has proved to be extremely helpful in my considerations of what to do during this swap.
Links I found helpful are as follows:

Sorry Guys, I decided to use this as my running parts list. I will add to it, change it, and so on as the project continues. It was originally a PM I sent to another member, and I posted it elsewhere (area 51). I figured it belongs here anyway.
Aftermarket ECU? Much fabrication?
Info? I got your stinkin’ Info right here!!.
First, let me tell you, a GSL-SE is the best model available to do a 13B Turbo transplant. It already has several things necessary to make the swap easier:
GSL-SE Front Cover - already have it
GSL-SE Oil Pan- already have it
GSL-SE Engine Mounts- already have it
GSL-SE Fuel Line Pick Up (EFI) - already have it
GSL-SE Fuel Injectors (good for primaries)- already have it
GSL-SE Engine Mounts- already have it
GSL-SE Radiator (3 core) - already have it

As you can see,MY
parts list is quite extensive. Luckily I am about 90% of the way there. I will be completing this list within the next 60 days, and then tearing into the car shortly thereafter. I anticipate finishing by the end of the summer if it all works out.
By the way, this does not include Labor, misc parts, time, time, and did I mention time?
Also TOOLS. Engine lifts, engine stands, Air compressors, parts washers, extra nuts, bolts, aluminum sheets for fabricating, etc. Labor is very expensive, as only a real quality rotary mechanic can do this, unless you know how to do it yourself.
I will be doing most of it myself, with the exception of the fuel system, Haltech installation, tuning, and Dyno testing. All of which is very expensive as well.
As you can see, it is not easy, quick, or cheap. It is quite an expensive toy that will NEVER be worth what you put into it. In other words, even if you do a real awesome job, that looks like factory OEM - you will never even get half of the money you invested into it if you try to resell it.
Why I am I doing this? Because I have always wanted a Turbo 1st Gen since my first RX-7 over 14 years ago. I plan to keep it as long as I can, and make well over 400 hp to the rear wheels. It will be my “fun” car. Not a daily driver by any means.
Before you consider this route let me recommend a few things.
1) Have another Car for daily use (pick-up truck recommended)
1) Don’t start until you have all the parts you need. (you will need more than you think)
2) Unless you want more than 250 hp (which is a shitload for a 1st Gen),
go another route.
1) Take your (12A) engine, rebuild it, Streetport it, get some nice headers and a good carb (Weber/Dellorto) and you’ll be at about 200 hp for less than $1200
2) Same thing, with a 13B = 230 hp, about $1500
3) Turbocharge your 12A. – Get a Holly 550, a Rising rate Fuel Pressure Regulator, an Intercooler, an old RX-7 Turbo with manifold (modified), a locked distributor, and you’ll be at 220 HP on a stock port 12A, 250 HP with a Street Port. – Less than 2K
4) Turbocharge a 13B. – Get a Holly 550, a Rising rate Fuel Pressure Regulator, an Intercooler, an old RX-7 Turbo with manifold, a locked distributor, and you’ll be at 240 HP on a stock port 12A, 280 HP with a Street Port. – Less than 2200
5) A Nitrous Oxide System. Good only on a Street or Bridge port, you must do this EXTREMELY Well, with plenty of safeguards to avoid blowing your engine. – Less than $500 for the kit, and Extra 50-75 HP over what you currently have.
I hope this has provided you with MORE THAN ENOUGH
information concerning a swap like this. Go to the RX-7 Forum, the web and Read, Read, Read.
Check this particular thread for all the goodies:
TII Swap itno GSL-SE
Good Luck and keep us posted!
(I just didn't like the italicized way a regular quote is used so I wrote where his quote starts and stops)
Now, as anyone looking at this thread should know by now, I am a very open guy that likes to share info and things for others. I've provided my list of links so far to things that have helped me learn and move towards my goal.
I'll keep posting here with pics, videos, and ideas and I'd appreciate those of you that are considering the swap and those I've featured above could help me out as well.
