Anyone recommend a place to get a lightened flywheel for a C20let engine? Pot type. Current one has loads of little cracks in it

yu dot gainnor lose power/torque/fuck al with flywheel weight. The only thing youi loose is throttle respone, but if your a goober, you agin on the lauch by prventing bogging. The lightest id go on a 200+bhp let is a std xe flat fly an clutch

to do this I would have to buy an xe clutch kit for the pressure plate and a let clutch kit for the clutch as running an F28. Already got two flat type flywheels which I presume are in good condition. This be the best thing to do?

Lightened flywheels are best suited for N/A engines aren't they? and don't they increase throttle response because the engine is able to pick up faster?

I don't know why they should be more suited to na cars. I know my Impreza is crap to drive around town because it though!

becuase high tuned NA engines rev so high, and the lighter the flywheel, the more freely it will rev. I don't have a counter arguement to suggest why it wouldnt' be suited on a turbo car though...

lol, the dreaded wireless keyboard strikes again! I was saying that you CANNOT gain or lose power/torque or anything thru flywheel weight.

you gain throttle response and reduce in gear acceleration times fractionally, but it can telnd to bog down off the line a little more if you cant drive.

I wouldnt bother going much lighter than an early xe flat fly with a let (6.7kg ish rather than 9.something)
