When doing a motor swap into a rt4wd people say to use the wagon flywheel.
i have used a lightened flywheel out of a eg civic and it works fine.
so i'm thinking that d series flywheels are fairly similar

    yep the only time flywheels get funny is on 88's they are a lil smaller.

    They are two step and specific to the model, they are in fact different (and more expensive to resurface).

    88's are the same size as 89's but with a different splinecount. 89's have the same splinecount as the 90-91's, but the surface area is smaller. Ive heard that they are the same 90-01, but I cant personally confrim that.

    I can't confirm 90-01 either, but I can confirm everything else he said. We ran into this trying to find the right clutch for my gf's CRX.

    I've got an '88 RT4WD transmission. I put a lightened flywheel for a '91 CRX on my motor. It came with a performance clutch, but the spline count didn't match, so I wound up using the original friction disk and the performance pressure plate. The flywheel is 12mm bigger than than the original (212mm, as opposed to 200mm), but even with the starter ring, it fit with no problem. I cannot verify, but I believe the starter would still have worked, too; the measurement appears to be the size of the friction area, not the overall size of the flywheel. That means my friction disk has plenty of extra area to make contact with the flywheel. It also pretty much eliminates any "performance" advantage I might have obtained in a conventional setting, but I was only going for lightweight.

    It works very well in my application.

    Here's the thread where I did it, occasionally acting like an idiot in the process (my only excuse is that I'm really not mechanically inclined):

    The clutch is another story... It was Very difficult to find one here

    There's only three to choose from. Just as long as you get the RT4WD T/O Bearing (22810-PH8-008) and the right spline count and the right outer diametre then you should be sweet. There's heaps of the right clutches in the country because there's tonnes available for D-series here. :)

    So... I am swapping a 93 del sol d16z6 into the 89 Rt4WD. theoretically, I can use the Flywheel and clutch disc / pressure plate with the 4wd trans, right?

    EDIT: I'm using ACT lightweight flywheel and street performance clutch / presure plate. Their website lists the same part numbers for 93 del sol and 89 4WD wagon.... so now I'm halfway into the swap. I will update on whether or not my stuff lines up as soon as i get it figured out.

    ANOTHER EDIT: The del Sol flywheel DOES have the same number of teeth, FYI. 109 I believe. And yes, the ACT Streetlight flywheel and Street performance clutch for 92-95 Civic / del Sol WILL work in 89-91RT4WD Wagon with a Z6 swap. Should work just fine with the A6 or any other D series that uses the same flywheel/clutch.
