Offroad-Express

Hey guys,

I've got a 3B manual in my BJ73 cruiser and I'll be getting a 13BT put in soon. Can anyone confirm if the standard clutch and flywheel from a 3B will be able to handle the extra torque of the 13bt turbo?

I do plan on running more boost and a 3" exhaust so will be making more than factory power, plus have ordered a lockright for the rear, all of which is going to put more stress on the clutch.

It has never slipped on or offroad but the 3B isn't a power house. It seems to hold on well because a while ago I pulled down a huge steel shed which had my 33' muds smoking on tarmac haha but that was 2wd without a locker/lsd.

Can anyone confirm?

Different size clutch on a 13bt. 3B is 15inch and 13bt is 16.5 or something like that

Well I'm planning on using the 3b flywheel since the new engine was from an auto. I guess the real question is has anyone done this before? I know the bolt pattern shld be the same since I have the early 13bt redblock.

Will a standard 3b clutch be enough or will I need to source a heavy duty one.

My brother has a 3b with turbo conversion which seems to handle it but don't know what clutch it has and is only on low boost.
