Just picked up a JDM 13bt with 5 speed trans and ECU and wireing harness off ebay!. It's going to replace my tired crate motor in my '74 REpu. Anybody done this? Besides Front cover change, fuel pump and maybe pan change what else might I need or encounter. Thanks for any help.

 

Just curious where your located at? Also there have been a couple people that have done the swap. Go to www.mazdarepu.com

Hey rotortuner, I'm the guy in Hansville you got the '74 red repu from a couple of years ago. Some day u'll see me and i'll see you and i'll stop and show off my motor, I can't wait.

 

I've got a complete 94 drivetrain I'm contimplating putting in a REPU.

Front and rear suspension, diff, engine, trans, modded PPF, ABS, everything. It'll be a 3rd gen in REPU clothing.

 

Even the struts?

 

turbojeff, Just do it!! lol :-p

 

Custom driveline maybe? I dont know, thats just a guess .

I'm another '74 REPU owner. I'm also currently screwing around with a rotary powered B2000. After that, I'm porting a 4 port 13B and rebuilding it for my REPU. Plenty of fun.

 

Well they aren't struts, they are shocks and springs. FDs have lower and upper control arms.

The rear subframe holds all the rear suspension, brakes and diff. So if I could either make the rear FD subframe fit the REPU or build a custom one that has the same pick up points as the FD. I'm sure the bed would need to be modded to get the shocks in the same position. It would just look like it was tubbed.

The front subframe holds the engine, steering rack and lower control arm mounting points. So I would need to modify the frame to accept the upper control arm mount.

Of course the driveline would need to be modified along with the PPF.

The only thing I'm worried about is the width. Does anyone know the width of the REPU? Narrowing everything would pretty much make it not worth it.

If anyone has a Yamaguchi book for the FD look on page 86. It shows the complete FD guts without the body. Imagine that in a REPU.

Didn't see the gen 3 part on your post.

 

jeff what widths you looking for ? wheelbase? engine bay between frame, something else? I'll measure mine for you.

 

I was wondering what the width of the truck is from the outer edge of the wheels. I found a original brochure on-line and a Road & Track article. What I found was:

REPU 67"
FD 68.9"

Track (I assume this is from the center of the wheels?)

REPU 57" F 56" R
FD 57" F and R

So the width is off but the track is pretty close. The bummer is the REPU track is narrower in the rear.

On second thought to this whole "proposed" project I'm thinking it might just be easier to build a completely new frame rather than try and modify the existing one.

Then again I don't know if I should even start this big of project. Maybe I should just restore it. I can get the bed, fenders, doors and hood dipped in a chemical bath to clean the up. The frame can be sandblasted and powdercoated for $300, pick-up and drop-off included!

 

the repu track in rear can be fixed by putting a 1/2" wheel spacer behind each wheel!

REPU can be made to handle well:

I like this paragraph best:

 

I was worried that the FD stuff would actually be too wide leaving the wheels sticking out past the bed/body.

 

Seems you could fix that problem with some offset wheels maybe.

 

then dont run a bed just make a custom pan or somethin back there
