(asked before im certain) how difficult-13b-RE conversion?
Hey guys and gals, I know this has been asked before, and I searched all over the forum for some answers, I got some stuff out of it, but still dont know how hard it would be, and how to swap the cosmo 13b-RE engine into my '87 RX-7. Any help would be...well...helpful! thanks a lot!!!

Your question does not have an answer if you think about it. We have no idea what your skill level is and for that matter any other thing that we would have to have some vague understanding of to give you an answer reasonably close to the truth. If you are some kid off the street with no money then it is a 34 on a scale of 1-10 but if your a good mechanic with plenty of funds then it might be a cake walk. As far as I can recal the "RE" engine bolts in but it would need some form of management and any parts associated with it are rare from what I have heard on this and other boards.

see, now was that so hard? and yes, what i was really asking was how it would fit in the engine mounts of the stock 13b engine, if i would have to do some heavy welding and fabrication of new mounts, or if it would drop right in...

That info is wrong Santiago, you have to either fab your own engine mount's or buy some premade ones, they are pretty freakin' expensive as well. I will try to look for the links to what needs to be done but it is a lot, and it is not just plug and play to any extent.

www.k2rd.com sells engine mounts that make the 13b-re a bolt-in. From there you will need a standalone EMS, and it is suggested you convert to single turbo. Its really not all *that* difficult, depending on your personal skill level.

Crap haha, my bad you are right, I was reading through and thought he meant the FD motor, it still requires quite a large amount of technical expertise and custom fabrication though or just a lot of money spent on pre-fab'ed parts made for the job. Sorry Santiago.

thanks both of you, and fritz, off the subject buy my girllfriend's dad goes by Fritz...funny...oh and anyone, if you could give me some estimation on costs (not including engine) on the whole project (i.e. mounts parts etc.) if I did all the work myself, that is making the mounts, and installing it all, it would be great! Thanks a lot guys!

One more post, this post more appropriately belongs in the 20b forum where it will get the attention you seek. The guys in that forum know their shiet as a good portion of them have already done the conversion, average cost of 20b transplant is 10g's there is an entire write-up on it. I just can't find the link but go to the 20b forum it is inside the Rotary Performance forum.

One of the hardest part about running a 20B is the ignition system.
We've just got a customer's 20B up and running using a trio of leadings coils (minus ignitors) and an MSD DIS-4. This DIS-4 box is still over $300 from Summit Racing, so it's still not cheap. This is running a Haltech E6K (discontinued), so it's still a grand to purchase a new E6X, and you still need to install and tune it.
The car still needs a front sway bar, as the 20B isn't going to allow you to run the stock unit.
You're going to have to run a BIG upgrade radiator, and it doesn't fit in the stock position without some serious cutting to make fit.
The 13B-RE Cosmo motor doesn't really have any of these issues.
In fact, you can run this motor with the stock 13B ECU if you want, but obviously you can't control the twin sequential turbos.

There is this one company, posted in the forsale section a while ago that sells a complete kit, hardwear, engine mounts, engine, and instrustions for $2700. Good deal if you ask me.

www.fc3s.com sells the Engine and the new engine mounts for 1900 total. One thing to consider with this is the fact that the RE's exhaust ports are tiny. So a lot of people go with TII housings and RE plates, which is the better combination. As stated you will need some sort of EMS, and you can run the turbos that are on there but not sequentially, they will fit though. You will need a FMIC and with that you are most likely going to want a new rad as well. Also the engine that you buy will probably have at least 30,xxx miles on it, so eventually it will need a rebuild if you don't do it at first. There are several people running with RE's NOTA944 TonyTurboII, they are the only two I know off the top of my head.

yeah, i was actually just talking with my mechanic today about the re, and its not that difficult if you have the mounts and a standalone, and other obvious items... the re is for someone who wants big power. im actually buying one for $800

Post count is over rated
the engine swap if you have the mounts is the same as putting any n/a or t2 motor back in an FC.you can even run the motor off the factory t2 ecu and t2 harness, the hard part is the fmic if you have to make your own and deciding which waterpump and wp housing you want to use.you will need at least 2500 to 3000 dollars to do this swap right and proper
