gonna drop a zetec into my wagon i figured an alu flywheel would add mpg and save wear and tear on the engine i read somewhere if u use aluminum flywheels you should not use the standard clutch as the thickness is not enough. i dont do any racing

Read the description. The clutch in that kit is a standard replacement clutch.

i missed that part aside from that is it a worth will expense will it save gas and wear and tear on engine
thanks

Google "aluminum flywheel mpg". I don't think you will ever pay for an aluminum flywheel on gas savings. If you want a peppier feeling ride and can deal with the driveability issues, go for it. It doesn't save on wear and tear, it might even cause more since they are designed to dampen engine vibration. That's my $0.02

I thought the zetec used a different clutch or flywheel than the SPI engine? That ebay posting says it fits both zetec and spi

what drivability issues would there be?

From a reseller:

An Aluminum flywheel.... with almost no weight. This lets the engine rev up very quickly and allows the engine to work easier due to the reduced weight spinning around on the back of the crank. This is fine as long as you are at full throttle and wide open throttle all the time like in a Road Race or Drag Race only car. As soon as you let off the gas the engine RPM drops instantly and the car slows down. In a road car this causes surging and bucking at cruise speeds and poor driveability and clutch engagement.

the clutch is the same from Zetec to SPI, but the flywheel is definitely different. The flywheel from an SPI will not work on a Zetec... but I will hopefully be proving that a flywheel from a Zetec will indeed work on an SPI.

I have a 9 lb flywheel on my BP, that's and 11 lb loss. It has shown no real driveability issues for me. Granted reverse starts and hill starts are trickier, but one just has to become a more efficient driver. I like that it decelerates slightly quicker, helps me in weight transfer!
