If you are planning for power later and only want to spend 300, just get one of the f1 stage 3 1.6 clutches and their chromoly flywheel. The flywheel is like 9-10lbs, and the stage three is good to 270ft lbs. It's only ~300 for both.
1.8 clutches always weigh more. There is no reason to use one on a 1.6. Heck a lot of people use 1.6 clutches on 1.8s to save more weight on the cheap. Every clutch has a 1.6 version and a 1.8 version, usually there is about a 20ft lb holding difference between the two versions of the same clutch. So unless you absolutely need that bit of extra holding power, just get the 1.6 clutch. It will rev faster.
Sir thank you I talked to philly since he had a 1.8 flywheel for sale but your right 1.6 is lighter then the 1.8 better busting getting 1.6 I was looking at stage 2 maybe get a lighter flywheel would help and just get a stage 1 kit just dnt know what company to buy it off.?
