Is it possible to swap a 95 twin turbo into a first gen rx7.
I have a 12a with 100k+ and doing bad. Im thinking of swaping the fd
for more power and more fun. If it is possible wat do i need to make this happen?

 

Also wat would be the most challenging thing for the project?

 

I've always wanted to do that....the lightest RX7 with the most powerful RX7 engine in it...would own.

 

you would have to change the front cover [12-A or a GSL-SE will work ] get a GSL-SE oil pan also you will need to change the flywheel to a 89-91 N\A to fit the stock tranney [it will work I have that in my rotary powered B2200 for the last 10K].

I know there is more but I am not thinking of it @ the momet...

WIRING Dan! How could you forget the nightmare which is wiring.

Assuming you get an FD engine with turbos, intake, injector assembly and computer intact, you need to get your way through the nightmare of wiring that comes even when you mount it in a GSL-SE! If you don't have an -SE (which I can see you don't because of your 12a comment), then you will have a little more fun. You'll need the RacingBeat mounting bracket to put the 13b engine into the 12a's place.

Get a Heynes manual for your car and for the FD, that way you can compare wiring diagrams to figure things out.

You'll also have to mount up an intercooler for your turbos, and probably drill an oil return in the front cover.

It's a very tricky swap to do, and not many people have done it. Many have put a TII into an FB, but I honesetly can't name a forum member that I know who'se done the FD-to-FB 13b-rew swap.

Though my friend Eric wants to try it next year I guess now's the time to start gathering information

WOW 4 replys in 1 day!!
thx but heres how i got my idea started.

very nice. 10 sec car

 

I bet if you go standalone it would be a million times eaiser to wire.

 

AJC13B actually had a 13B-RE Cosmo engine. Not the 13B-REW which is from the FD.

 

I was thinking of what I did to my mazda B2200 and just left it carb I don"t have the time or the brain cell's to figuere out all the wiring "night mare"but hey I did say that there may be something else I was not thing of and you thought of it WTG......

Are you asking about swapping the engine itself, or the engine along with stock turbos and all the stock emissions equipment, stock ECU, and wiring? They are two very different projects! Swapping the engine is no big deal other than the deciding how you want to mount it (front, rear, or whatever). Trying to swap the whole mess is either masochistic or deranged. You will need an intercooler in either case, and for any turbo.

IMHO--and there are those who would disagree--the stock turbos are junk and if you go to the trouble of swapping engines it only makes sense to upgrade them and get rid of all the useless plumbing, computer, etc. at the same time. I agree with Steve-OOH it makes things a lot easier.

 

isn't there some issue with using the front-mount front covers on an REW as well? i think it was either a clearance problem with the oil pump or else a difference in the bolt configuration. i can't remember which ...

 

there is someone who's done it and he posted it on this forum. He is from Arkansas. First one to find the post gets a cookie. BTW he used stock twins and wiring.

 

The front cover bolt pattern is diffrent as far as the oil pump clearance I have had No problem with eather of thoes at least on my set up....

It was me, I had to make a custom engin cradel and trany mount.

 

Pics please!!

here are some crapy pics when I first did the swap 8 months ago, I have changed a couple of things and are about to get it painted, hopefully by the first of january.

 

Nice!!

 

Nice pix.

Whats a good place on the net that can help me.
Also where can i buy a new rebuilt 13b-rew engine with everything.
harnesses and so on.

 

You're lookin' at it. This is the best you can do. This isn't a Honda you're talking about. There are no kits, no magazine writeups, few or no websites detailing how people have done this in the past. The specific swap you speak of is practically unheard of around here, thrown aside for the easier TII swap which yields similar benefits.

Honestly dude, you'd better have a ton of cash, lots of determination, some ingenuity and good mechanical/electrical/metalworking skills or connections to do this. Have you swapped engines before? What's your previous car-related experience?

All I'm saying is that you should be aware and prepared for what you're walking into. The only reason I've seen people attempt this swap were either because they came across the FD parts for really cheap and couldn't pass it up, or because they had the experience, the money and people said it "couldn't be done". That's not technically right. Anything is possible if you throw enough time, money and determination at it

And with those words I'm gonna wish you the best of luck in this project. Keep us apprised of your progress. I, personally, want to know every detail 'cause I'll be helping a friend with this swap in the upcoming year

Well im just finishing my first project. SR5 to GT-S coversion. I have the garage and most of the tools i need. Ist about 4 weeks now and almost done. Wires were a bitch though. I might not be the one swaping it, my friend knows a guy that could do the swap for 5k the most. I know i need the engine, tranny, and engine mount. But wat else? I could take care of the suspension. I already swaped the drums from the 83 and got LSD from 84 gsl-se. FC, FD, and 240's are the only thing i hear about. I just want to blow smoke in their faces when the see wat my little fb can really do.
Also wats the best engine to use for drifting for the FB, FC NA, FC T2, or the 13b- rew? and how do u put pix on here?

 

For remans and other Mazda OEM parts, the best place is Malloy Mazda, 1-888-533-3400. Talk to Ray Crowe. You can get used harness and other parts anywhere such as junkyards or the for sale section. I might be selling a new reman engine in a couple weeks.

If you use an aftermarket ECU, it will not only be a lot easier, but also more powerful, more reliable, and easier to tune. More people have done that way. But unless a load of free parts just fell in your lap, you are putting the means before the end.

Can i use the sam gas lines and gas tank fuel pump and the other things.
Basically wat do i need from the old car?

 

Hey Max

Well I guess you do seem pretty set to tackle the project. Unfortunately you're going to need to revamp the fuel system too (another thing I had forgotten!). The stock fuel pump puts out something like 3psi steady, and barely suffices for it's current use. It would be better to get an aftermarket fuel pump and a rising rate fuel pressure regulator for this project. Check the 3rd gen section to see what those guys are using for fuel pumps. The TII guys also use similar setups. Heck, I think some of the turbo 1st gen guys do too

For posting pics, it's always easier to host them somewhere online and then just post them in [ IMG ] tags. The forum's limit on picture size is small because of the sheer number of users and images that are here at any one time. Bandwidth would be a nightmare if they let everyone upload and view lots of big pics.

The tank should be okay, though You *might* want to get a tank from an '84-'85 because those had bigger pipes and held more fuel, to feed the GSL-SE's FI 13b. Even the 12a models of '84-85 got those tanks..
