... I'm wondering what all would be involved in installing a 13B-REW from a FD into a 79 SA?


I've found a number of them on ebay, and I'm just trying to gauge what all it's gonna cost, both time and labor, in installing the REW.


If it's any consolation, the car currently has a 13B from a 76 Cosmo in it right now. I also have a GSL-SE Tranny, unless something else is preferred.




Also, is it possible to swap the hubs and everything from an FC onto a SA/FB, so that I can get that uber-desirable 5x114.3mm bolt pattern?

 

four little rotors is right - I just realized you're using shots of the tiny grup rotary engine in your sig - the rotors from a remote control airplane engine

 

I've been on this forum for a few years and I can't remember anyone using a REW block. If I remember right it's because you can't just swap the front cover for a FB one to make it a "bolt in" engine.

Oh yeah, most people use a T2 trans when going turbo 13b. The torque of a turbo 13b eats n/a transmissions.

 

why not ask those companies that have built 4 rotors in the past?

 

I am helping a friend out with the REW conversion ATM, not too sure about the left hand drive models, but the twin turbos wont fit in his FB due to steering box clearance issues, the idler arm may give enough room.

and I'[ll get back to you on the timing cover thing, I believe it can still be done, have seen a FB with cosmo block running single hiflow FC type turbo.

 

You just had to steal my avatar and put it in your sig, didn't you?

 

i may be mistaken, but i was told that the RE and REW motors have different housings, and basically the 12A or SE front covers will bolt up to an RE, but they will not bolt up to an REW because of some clearance issue with the oil pump ...

 

I haven't heard anything about clearance with the oil pump... as far as I know in fact, it is considered a good upgrade while the cover is off ?! I think the reasons for the lack of this type of swap vs 13B-RE cosmo, is one of cost. Why pay $1000 more for pratically the same engine? Another is one of electronics, I think there is more of it on the REW, so its a more diffucult swap. The twins on either causes clearance issues. if I remember Mike-P-28 tried to fit them, not sure on that one.

 

It should basicly be possible (everything is )
From what I hear the 12A front cover WILL bolt onto it.
Both cosmo and FD 13B's are largely the same. If it works with one, the other should work too. But indeed, costs are a major factor here.
I think these kind of swaps are easiest if you use an aftermarket ECU, and maybe drop the TT setup, in favour of a single turbo. The twins need some sort of electronics to control them, not making installation easier. But again, both Cosmo and FD units are very close. It should work, it's "just" a lot of work.

 

where did this come from?



I put my sig in the first post of the thread so people would know who I was... and that they associate the whackjob mentality to the right person.... me


THis thread is for my OTHER car, the 79 Widebody, that I am acquiring from zyounker.

 

That's RADIO control to you mister...lmao, j/k

 

A guy here in GA has the REW in a first gen. I think his name here is Rotorious7. You may want to PM him.

 

EVERYTHING is possible if you know how to weld (or fabricate for that matter)

 

well, as i said, i may be mistaken ...

anyways, i don't have the time right now, but i remember someone posting a link to somewhere that all the differences between the RE and REW were listed. i will try to find it and link it here later on after i get home from work ... hopefully i can find it. if not, then i'll whip out the old notebook i have with "all things rotary", and type the differences myself. i have it, it's just that i keep it buried because it's so depressing to realize i don't have money for either one.

 

13BT and 13BREW differences
it includes some info on the RE as well.

Oh, and here is a 13BREW in an FB. It's been done. Stick to the Four Rotor, I have my $100 waiting to paypal you when you complete it next year.

 

He wants to do both I think!!! One busy man that is !!!

 

Now that I think of it I think it has something to do with the FD's crank trigger. I'm not sure you can put the FD crank trigger onto a FB front cover with out some custom brackets, or maybe you can just use a FC CAS and put the crank trigger aside. hmmm...
To the guy who was wondering if the stock twins would fit in the LHD FB chasis they will, Mike-p-28 tested it out.

 

Yeah but if they arent converted to non seq operation, its really really close. But who wants to run them in seq mode... You'll need the stock co,mputer to do that , but there might be a way that it can be done w/o the stock ecu. But anyways, they fit I tried it

 

Oh yeah, forgot to ask this before.

Why do you want to do two swaps at once? One is painfull enough let alone comming up with a custom 4 rotor AND doing a 13b-rew swap at the same time. I've been working on my 13b-re swap for over a year now and I'm still not done (yeah I'm a little slow). It really drains you doing this type of stuff, unless you have a full shop at your dispense I'd suggest doing one at a time. Ask Directfreak, he had all the stuff to do the swap to his FB. He was thinking it would take about a month solid. I think he started ripping into it in Aug and he's still not done.

Local shop here has done both recently..check under Projects

 

if ur cars left hand drive, just drop it in with the twins and try find someone to wire up the ecu for u, much cheaper and doing it in steps makes it easier, unfortunately down here with right hand drive i gotta mess with turbs and ecus just to get the engine in ugh!

 

Ohh grasshoppa... because I am a bit of a massochist I am also planning on a 20B swap into a 929, and a 20B swap into a Mazda B-Series (that's been bagged, and is currently laying frame on 20's).



You see... I get these ideas in my head.... and then it just goes from there. I gotta get the idea of more income too... hopefully it flows just as well as the swap plans.
