Hey. This is my first rx-7, and i jumped for the first one i could get. I just love the cars. Downside is that its an n/a and i just cant drive around like that. I can fairly easily get a 13B-REW, so thats the easy route to take. I need to know what i need to get for this. I know i have to find engine mounts since the fd engine mounts on the rear housing area, and the n/a transmission wont take the power. I basically need to know everything to do. lol.

If you search you will find everything you need to know.



The REW mount kits are pricey. The swap REQUIRES a standalone. You don't need a TII trans, but it is recommended. You need a FMIC from the get go. Larger fuel pump. The twin turbos kinda fit, a single kit will set you back more than the cost of the engine itself. Since you have a 1986, I can only hope it is a 5 lug car. If not, you need all the 5 lug swap parts, and TII brakes, etc.



Kinda pricey don't you think?



Better idea-



Do a TII swap.



Even better-



Do a 13B-RE swap (Cosmo JDM)

I offer the mounts, click on my sig to order them. There is another member on this forum in the middle of the swap right now, and given how many mounts Ive sold, there should be quite a few more in progress or already done.



Heres a few links:

and you'll need to swap the flywheel ive been told. not sure though.



i once wanted to swap in an REW. i went with the Turbo II though. mainly because it drops right in. and with half the money, you'll be just as fast. or faster.

First off, let me just ask, have you done the swap before, or had any first hand experience with it, or my swap mounts for that matter?



Anyways, Ill answer any questions regarding this swap you or anyone else may have that arent already answered in the threads I posted above.



Heres some REW specific information.

Ok. Well im going with the REW mostly cuz of availability of everything. Also, after many grueling hours of research, ive read that i could mount a custom crossmember at the rear of the engine cradle to mount the stock FD mounts to. That came from another guy who actually did the swap. Also, i guess everything will slide in, with the exception of making custom oil cooler and radiator hoses and a front mount intercooler. All that i can custom make myself and mount myself. I enjoy getting creative with things. I read that the flywheel will accept the FD clutch, but will the clutch fork from the fc tranny actuate the pull type clutch? and what should i swap the rear end to, keep it independent fc? I plan on seeking out some track days with this car, road racing style

sorry. i need to correct myself. If i use the stock FD flywheel, can i get a push type clutch to mount and just use the stock T2 tranny and bellhousing. i know it will mount all nice nice, but will the clutch work?

Quick shopping list:



- S4 tII transmission

- S4 tII clutchkit

- S4 tII flywheel

- FD Automatic Counterweight

- FMIC

- Motor mounts from Mazdaspeed7

- Aftermarket ECU - Cheapest way to go is Power FC (800) and the wiring adapter from Banzai (300). ( No wire splicing required )

- Fuel pump upgrade ( I went with Walbro 255lph )



After this stuff - its up to you as to what mods you want to make. Before you decided to upgrade the turbo's, make sure they will fit.





Also, you might have to de-power your steering rack or get a non-powered one. I deleted my AC and Powersteering to make room so I could actually work on stuff. Also, I learned this one the hard way, Dont buy any strut tower bars before the engine is in. I bought my 325$ bar and now - its garbage.

Mazdaspeed7, your going to have to pardon my ignorance again. I misread the information youve given to others and thought the clutch had to be of the same type of the engine. I now understand its of the tranny. Cant believe i messed that one up. Im top of my class in school in the auto tech department, and its pretty embarrassing to mess that one up. lol. so what would i need exactly to mount an s5 t2 tranny to the fd. everything related also.

You dont want the S5 Transmission if you've got an S4, you want the S4 tranny as it will bolt RIGHT up to your car. I ran into the same problem, I've got the S4 tranny and an S5 car.

And for the tranny to bolt onto the motor - look at my other reply.



I forgot - You'll also need the corresponding starter to the tranny/flywheel combo.

Yes I helped a friend do a REW swap into an FC. I also helped a friend put a 13B-RE into an FC. The RE is way easier, that is why I threw it out there.



Its not like I am taking away a sale from you, chill out.



Also, the TII is plenty capable. One of the local guys has an FD with an S5 TII block, S4 low comp rotors, TII LIM, FD UIM, single turbo, FMIC, Power FC and Meth injection. Puts down a reliable 400hp.



Nothing wrong with the TII engine!!!

ok. stupid question. whats fmic

Front Mount InterCooler

ah. sry. i can just custom fab everything to mount the fd one temporarily. thats no issue

and if i get the fd engine harness, ecu, and all the ignition and such i can use that instead of a stand alone. this is all just to get it going and usable.

You can use the FD harness and all components, but making it work with the FC dash is a little more work. Using both FSM's you can figure it out pretty easily.

yeah. there is nothing wrong at all with the fc, i just want an rew. lol.

Honestly... Take my advise, I'm doing the EXACT same thing your doing. What I'm doing is the easiest way I've seen to go about it, with the exception of cooling.

ok. so if i go with the standalone i need to know exactly what to get and how to set it up. Im like, amazing at everything. except wiring setups. lol. thats the huge weak area for me. which figures

and custom mounting the fd fmic will work? with some tweaking of the tubes of course.

Use whatever EMS your local tuner is most familiar with. If you are confident enough to tune yourself, pick the one you feel most comfortable with. Haltech, Microtech, etc. You could also use an Apexi Power FC.



For an FMIC, I would get your hands on something better suited for an FC. The FD intercoolers and pretty thick and the set up is not ideal for an FC. eBay is your friend here!! I just picked up an nice 24x12x3 XS Power FMIC from a local guy for a great price, and its pretty damn sturdy.

yeah, about local tuners, being in the NE, specifically mass, it sucks. noone really does anything, bunch of snobs, and muscle fanatics. There may be one place, my friends father owns it, but they do vw... https://www.nopistons.com/forums/pub..._DIR#>/sad.gif

and waht would be an average price to set up the electronics on this, including an ecu.

A standalone can set you back anywhere from $800 for a PowerFC, to over $2000!!!



Most setups that will work well for rotaries are less than $1500. Haltech E6X, Mictrotech LT-10S, etc.

ok. now for my slew of technical questions. with the power fc handling the rew, will it handle the remains of the fc? and what do i need for that to work and hook into all the stock gauges

Now I am out! The REW we did, I only help on the engine install, intercooler, plumbing, etc. On the RE, it was basically a race car, so all gauges we aftermarket, push button starter, standalone.



Now, you can use a PowerFC on a 2nd gen, but you need to use the patch harness Banzai sells. So I wouldn't think there would be alot involved with the REW, using the FD harness.



I would wait for someone else to chime in though.

And for what its worth, I only use the stock gauges for Fuel, Voltage, Tach and Speed.



Now for your setup:

-The tach should be a non issue, simple to make it work, just like any other tach.

-Speedo will be fine since you need a TII trans and it is cable driven.

-Fuel, same deal.

-Battery voltage, should work

-Oil pressure and coolant temp I believe you only concerns, but I use Autometer for that.

Amen, I'm using all stock guages, And unfortunatly, I couldnt find a way to do this with getting the dreaded dual guage pillar pod. I've got the Oil pressure and coolant temp on that. I need to find a place to my boost guage and Turbo Timer.



If you dont have to worry about emissions... I'd recommend changing to non-sequential.



http://www.banzai-racing.com/ - You can get block off plates and the wiring adapter.

http://jappartsspecialist.com/product_info...products_id=197 - Power FC - Lowest Price I've found.



AS for the Fuel - I upgraded my fuel pump.



But then again.. you might have a budget. Things cost money. Money limits options.

well thankfully im a very race oriented builder. if it doesnt hold a good function, its out of the car. I will be autoxing this at some point, hopefully upcoming season will be spent tuning and testing. so i am def going for the fuel pump along with it

Well. When you get to the assembly part, I've got a rear strut-tower bar I'm not using if ya wanna buy it slightly discounted from Mazdatrix price.



Its never been installed and I dont wnat to tear/cut my interior.

thanks. but the rear seats are the one thing im willing to keep. gotta scare the crap outta the friends sometimes too ya know. but yeah. whats a list of ecu's that can pull together this swap. like, best to worst reliability/compatability wise

I'm pretty sure you can keep the seats and use it cant you? Its not a multiple point bar.. just the strut towers..



Hmm. Not sure on the layout of the 2x2.



Honestly. Get an idea on who can tune what in your area and go that route.

there really isnt. unless i wanna drive, or tow, the car like, 3 or 4 towns over

Sounds to me like your going to have to tune it yourself then. IF the REW is stock when you get it or at least CLOSE to stock, you can drive it after plugging it into the Power FC ecu how the standard settings are. Then you can drive it to where you need to go for tuning.

could i tune it myself with a laptop? or the commander?

With the Power FC you can tune it pretty easily. Get some maps similar to what your set up it and fine tune from there.
