Im sure this has been posted a million times before, but i would appreaciate any feedback. I have an stock standard ED with 4 speed auto on gas.

I have come across an 89 EA with a 5-speed box and LSD. Motor is shot, exterior rough, interior not bad. It has extractors and 2.5" exhast only a couple of months old, bathurst globes and he wants $1000.

What i want to do is take the 5speed and LSD and put it into the ED. It should be a straight swap over ,regarding pedals and consoles but how about the computer management systems. ARe there any major issues on this?

Any help will be appreaticated.

Theoretically shouldn't you just have to remove the auto computer.

True the auto computer is attached to the pedal box so will come out when you change the pedals over

With EBII onward the trans computer is part of the engine ECU. I'm pretty sure you need to plug a manual ECU in when you change over to manual trans - something to do with correct idling - and there's wiring involved for a switch on the clutch pedal.

Bass Crazy knows all about this stuff.

Diff will not swap over. Internals will but the trailing arm mounts on the housing are different width. Unsure about 6 but V8 did not have integral ECU for trans until AU.

Ah, - sorry, I should have specified - yep I was meaning 6 cyl.

Hey fellas.

Firstly, I'm pretty sure the diff could be mad to fit by using some shims on the control arm bushes to make up fir the difference in width. If not, just get a diff professional to change over the internals, as mentioned above. Oh, and the connection to the tailshafts are different, but easily cahnged.

As for the manual itself. I have a EB box in my EA, so vice versa should be a straight bolt in.
The wiring is pretty simple.
The clutch sensor connection is already located just above the pedal box, so when you install the new pedal box, all you will need to do is plug in the clutch sensor. Its a grey plug.

You will then need to bypass the neutral starter which is a matter of shorting out two wires, this will allow the car to start. I'm not sure of the exact wire colours for this, but I'll find out if ya like.

The reverse lights are a piece of cake. Its just a matter of removing the existion auto loom, and plugging in the manual one, wich should all match up to the gearbox.

The original 4 speed tailshaft and crossmenber can be used.

The ECU should be fine. The auto can work with the manual box, but not the other way around.

I just finished doing a manual conversion to a VL yesterday and I gotta say, there a hell of alot easier to work on then the EA's etc.

Good Luck.
