you gonna run stock twins?

 

cant wait to see this get up and running

 

^ you cant and even if you do find a away it will be such a pain in the *** that you will just go single anyway.

 

i belive so....

 

13 bre's came automatic, which 5 speed are you planning on using?

either way, get the t2 drivetrain

 

Contact the guys at Gotham Racing and ask them to take a pic of the engine bay of the 90 Rx7 13BRE Convertible they have sitting there. Its waiting for a replacement turbo. I don't know if they can or not. But I will once I get it back to Houston.

I bought a 13BRE from Japan...it was beat up. 1st rebuild was done with FD housings, T2 rotors. Single Turbo. Everything else was 13BRE. Current rebuild has been done by Gotham. Same basics as above but with upgrades. Rotors milled for 3mm seals. Balanced. Rotor bearings from Mazda Comp. Cerma coating etc etc.

By using the FD housings it made it very easy to use the HKS stainless exhaust manifold with the T04 mounting. The turbo is a Turbonetics...jury is still out on what I think of their product. Drivetrain is T2. Control is done with Microtech. Yes, the components are worth more than the car but unlike Warren Buffet...I decided to spend my billions on an old Rx7.

Warren! Pass the djion ketchup.

i have this setup also. i just bought a good 13brew i think. came off a cosmo. i have a haltech. but i need motor mounts. there is a guy who sells them for like 200 bucks. anyone know where to get them cheaper. ill run the twins non-sequential

 

I'm having the Cosmo swap going into my FC, but right now it being ported and getting preped for a complete rebuild. Anyways if you need info on the swap call the shop in my signature and ask for JR. He has swapped 13B-REW, 13B-RE, 20B, and numerous S5 into FC's and FD's. He's been dealing with nothing but rotaries for over, I think, two decades so he quite knowledgeable when it come to our RX-7s'. -Keith

 

I have a T2 driveshaft if anyone wants.

 

Can't you use a stock TII turbo/manifold to get you by on a cosmo?

 

yes, but it would suck. hard. the -re intakes ports are HUGE. the stock turbo can barely hold 7psi to redline on a stock port t2, i can only imagine how soon in the powerband it would die out on an -RE.

 

yes. a tii drive train will work with a cozmo. you need to swap out the front case of the engine to the fc. the cosmo case's pullies and coolant are in different locations. the coolant goes to the driver side when on an fc it goes straight forward on passanger side

it does have an automatic trani
you can put a tii trani on
you need to rig up a tii ecu to work for the cosmo because the stock ecu is ment for automatic trani
you can also use a programable ecu. thats what mine has
"mines" ecu
i doubt you can use the stock manafold on it. i am just having one fabricated

 

^ What Mazda Stuff said.

Gotham is a very good shop.. they're all great guys and like he said, they have a 13B-RE FC Vert sitting in their garage. I'm sure they can help you out.

 

****, keep me up dated!

 

You can easily run the stock twins in parallel if you don't have the JC ECU. In this case she does, so if the loom's also there and the plumbing is complete there there's no reason why they couldn't be made work.

Nope, the JC 2-rotor engine and trans have seperate ECU's. The engine ECU has no problem running without the auto box and it's ECU. I know this becasue a friend converted his 2-rotor JC Comso to 5-speed. The 3-rotor is a different story...

That will just be a stock ECU reprogrammed by Mines, not a programmable ECU.

You can. An FC manifold and turbo will bolt right up.

 

gotta love nzconvertible... i wanna pick your brain

great project jessica! i wish i would have gone the re route.... w/ what im investing into my new motor, i could have done a 20b-re swap no problem...... sucks when you dont think ahead but oh well! at least you are thinking ahead! cant wait to see it complete!

 

i see so far ahead i am already budgeting my fb 20b project 5 years down the road jesse. haha. i think so far ahead i already have an order for the awd conversion for my caliber once the warrenty runs out at 60miles/60 months.
rofl
j/k.



thank you nzconvertible. i might ask you for your phone number.

j/k
but not really i might need to pick your brain aswell. i must learn. must feed. have hunger. must gain knowledge!!!

 

Awesome hope it goes well 4 ya, sorry i wont be there to help

 

the turbo ii tranny fits but there is no hole for the starter. and the drivers side mount is different. there aree some people who make these, does anyone know where to get them as i am doing this swap myself.

 

This doesn't make sense.
The rotor housing has nothing to do with the turbo exhaust manifold position or turbo clearance to the lower intake manifold.

Someone on eBay is regularly selling these mounts for $99.
I cannot vouch on how well they fit.
All I know is that the old K2RD Cosmo mounts fit perfectly, even with the stock twins.


-Ted

 

Actually, the upper radiator hose comes out straight forward from the engine.
The lower radiator hose comes out similar to what an FC 13B does.

Hey Jessica, can I have your RE pulleys if you dont need them. I need the Main/ACC, Water pump, Alt pulleys. Be glad to pay you for them. PM me if you would. Thanks

 

Get this done before Sevenstock!
