RB20 flywheels

[wga240]

I've been looking for places to get a lightweight flywheel for the RB20DET and ran across this page. If you scroll down to part # N016 for the RB26DETT it appears that the flywheel for the RB26DETT (250 mm model, whatever the 250mm means) will work with the HCR32 RB20DEt the ECR33 RB25DET, and several other engines. Does anyone know if this is true? I want to make sure I'm reading that table correctly.

I'm not looking to buy one just yet. I'm just trying to go ahead and research where to buy one when the time comes. These are aluminum flywheels made by Top Hat Performance, right? Do you know approximately how much they weigh?

if they say a 26 will with with the other ones then yes they are interchangable, im using a rb20 flywheel on my rb25. the only problem i had was one of the alingment dowels on the flywheel was about 1/4 inch off when installing the clutch. all of the bolt holes lined up 100% perfect but just the dowel was off. i just filed out the hole, problem solved.
