The pricing is not so good, way too expensive on these stuff.
I don';t really that flywheel is pretty much useful as the drop-in replacement is because that when you greatly reduce the mass of flyhweel you may hit the problem on the balance of the crankshaft then resulting higher engine vibration and low end torque even the flywheel is balanced, that';s the reason why BMW balanced the flywheel and the crankshaft at the same time on the M engines. and it looks like is not possible to put it on the manual tranny. YES, you can get more high-end HP but trade-off the low end torque and higher vibration by doing this.
Okay,why BMW doesn';t make the flywheel of M engine with 3Kg or less?
That is the idea.
The under drive pulley sets..well no idea on the gain would be there is a number comes out from TMS, they claims can get 10+ HP on E46 M3 with lightweight underdrive pulley only, but how much HP you can gain on the E36 325 or 318? probably you';ll get less HP on that. but lightweight underdrive pulley is good to have only if they didn';t changed the original pulley ratio then you can go for it.
Electric Fan set, probably good stuff to go but that is all about the $.
You probably can get 10+HP or something but not 20 or 30HP, but it';s not very worthy anyway with these things(in comparison of $), it just works but noone knows the idea on how much gain would be only if you dyno';ed it.
Do the seller dyno';ed the stuff anyway?
Just my 2 cents.
