Has anyone put a B6ZE ( Mazda MX5 NA ) drivetrain in a KE70 2 doors 1980 mdl.

if you know can you please share the info. i don't seem to be able to find anything.

I haven't heard of it being done, but I've always thought its a great idea.  The only surviving RWD 4cyl in mass production, most of the options are ancient or expensive.

Its got to be easier than converting a FWD to a RWD gearbox, and you can buy a recent low-Km motor & 6-speed.  There is plenty of knowledge about warming that motor up too.

Go for it!

Its probably been done, What info do you want?

-Make sure the sump fits around the ke70 cross member. 

if it does, drop it in and make the following:

- engine mounts
- gearbox mount
- custom 1 piece tailshaft to an LSD diff. 
- Efi fuel system
-Either fit the mazda radiator,. or find one about the same size that fits with the pipes on the right side.
-Find mazda wiring diagram and figure out how to wire it up in ke70.

skids! (after you fit an LSD diff, good brakes and good suspension)

Cheaper and arguable alot better to just buy an mx5 😉

i have already bought the motor and transmission from a mx5 91 mdl 

it's going in. 

the info i am looking for is. 

has someone done this before. what can i do before hand to make my life easier while doint this. 

no reason to reinvent the wheel.

do i need the fabricate the transmission tunnel or the firewall ?

 

( this is essentially my first "small car" build. i originate from iceland. and have built a couple of "superjeeps" ) - so i aim to do everything myself.

 

i got the motor + gearbox, +ecu + radiator + driveshaft ( for about 350-euro. )  

 

to start with my plan is to get it up and running. and keep it stock. 

 

the stock internals of the B6ZE seem to be able to handle 250 bhp if you add a turbo kit to it.  ( that is what i am aiming for, so simple and nice )

 

Interesting possible co-operation between two great Japanese car manufacturers, I read recently, in researching later model RWD engines suitable for Rolla transplants/conversions.
