Alright everyone. Been working on this issue for a while now and have finally hit a wall. Symptoms and info are as follows:
I have a JDM 1988 GVR4, I upgraded the clutch with an ACT2600 and lightweight flywheel.
Decelerating with the car in gear with clutch engaged makes a loud grinding noise that is extremely aggravating. The noise disappears when I push in the clutch pedal and when I accelerate. It will also disappear if I merely set my foot on the gas pedal and give it a tiny bit of fuel. My transmission bellhousing has grind marks on it from the pressure plate. I ground down the bellhousing a few millimeters where there was visible wear. Everything else on the car as been given a once over. Carrier bearings are replaced, rear diff is strong, no play in any axles, passenger (US driver) side axle carrier bearing is solid and flush with mounting point. Clutch is not dragging and has been adjusted per Jack's video and engages strong. Has anyone ever had this issue putting US market clutch into a JDM trans? And what are my best bets at resolution? I'm going to order stock JDM parts and put those in and see what happens. If you can help out at all, its very appreciated. Thanks for reading.
