Can anyone shed some light on what will have to be changed. Both cars are manuals, the 97 has the t45 and the 02 has the 3650. From what I understand the 97 has a 10.5" flywheel and clutch and the 02 has a 11" flywheel and clutch. I plan to get a new flywheel and clutch kit but I'm unsure on which size I need to get. I will be keeping the t45 in the car as a personal preference so does that mean I need to put a 10.5" flywheel on the 02 motor or can I run 11" flywheel and clutch in the t45 bellhousing an not have any issues with the starter?

The car also has 4.10s in it and I wondering what type of flywheel would be best to still daily drive but rev up quicker.
As for the clutch I'm thinking of going with the Exedy Mach 350 Stage 1 Organic Clutch Kit.

Any advise is appreciated.
