Light flywheel and crank pulleys

[1fast2liter]

I have ran both in some other cars in the past. Do our cars react differently to a lighter crank pully and flywheel? I know subies if you run a lighter flywheel you need to run the lighter crank to. So are we externally balanced or internal... thanks

no experience but ECS said they pulleys increase response however removing the harmonic balancer crank pulley causes increased engine vibrations

he didnt mention that there not good for your bearings, but i asked along time ago too on here and a guy posted his cracked seal and blown engine from the lighter pulleys

the usual answer to this buy it if this is only left of things to add. otherwise spend elsewhere

only had a flywheel experience in a e36 and it was very responsive, went out only only a year and a half later though

id buy a fluid dampr and light weight alternator, steering a/c pulleys if i was you, no flywheel
more reliable and responsive

Were do i get a fluid damper from? Never herd of that. Ive used lighter flywheel s in the past with good results. Just not sure what our cars can take

Lighter is more or less seen as ok, but don't get underdrive pulleys. I'm going to get a Fluidampr to go with the LWFW (help weight and vibration), but will otherwise skip fancy pulleys
