Clutch Compatability for EA81 4SPD D/R


Recommended Posts

Can I run an XT6 clutch in my stock Brat transmission w/ an EA82 Flywheel? Will everything fit properly (using an EJ)?

 

Has anyone done this? I'm curious about people's experiences w/ the EA81 D/R trannys holding up to EJ's unbelievable power capabilities.

The input shaft of an EA81 D/R 4-speed is smaller then the input shaft for EA82/ER27 4wd transmission. You may have to use a clutch disk from EA82T 2wd Transmission but I'm not positive if that disk is compatible with a XT6 pressure plate.

I know that some people out there were talking about using EA81 4SPDs for their EJ swaps a while back.

 

I'm hoping to figure this out before it happens rather than during so that I can have the parts on-hand for the swap.

 

Can I use the stock EA81 flywheel on the EJ?

You can by all means use a stock EA81 flywheel and clutch setup on an EJ.

 

However, I doubt it will hold the power of the new EJ motor. Apparently Archimetis ran a stock EA81 flywheel/clutch/PP on his ER27 (XT6) powered hatch, and he had a lot of slippage going on.

 

His solution was to run an XT6 flywheel and PP with an EA81 clutch disc.

 

A custom Throwout bearing was needed to match both the EA81 input shaft and the XT6 PP. He used one from either a mid-80s or early 90s Nissan truck, he couldn't recall exactly which model, he just took the parts to NAPA and found one that worked.

 

When I get my hatch together I will be doing a clutch setup like this and I will make note of the exact components necessary for everyone's benefit.

Great, that's just what I needed! I'm wondering how bad the clutch slipage is w/ the stock assembly as I would like to go that route as a temporary clutch and transmission setup to be followed by an EA82 tranny w/ good clutch.

 

As long as it's drivable, I can handle some clutch slip. :drunk:
