This is a long shot, but I thought I'd ask here. I bought a JUN 2JZ-GE lightweight flywheel for my 5-speed IS300 (also 2JZ-GE but with a W55 transmission) thinking it would bolt right on. But I guess that's not the case. Have any of you with the 2JZ-GE 5-speed SC300 ever used a JUN flywheel? I would really like to know how I can use this part on my car. Thanks!

 

the is300 is a w58 trans same as the sc. whats the difference with the stock flywheels and the JUN one that you bought? i was almost 99% that the transmissions were the same because the clutch off the is300 is interchangeable with the sc300.

 

some people do the W58 swap but it comes with a W55

 

The IS300 is actually a W55
