little help knowing what to look for

[steve alan]

been searching around for a mass flywheel , contacted sellers on fleabay, how do you know which is the correct flywheel for the 150 bhp sri vectra?
sellers come back and say yes suitable for your car but amiss as to how to tell difference between 120 bhp & 150 bhp flywheel,
any help on what to look for part no/or anything else like numbers on flywheel?
and how often do they (flywheel)and the belts timing/etc need too be
changed,thought I saw an artical stating every 60k seems not a lot of mileage for a flywheel let alone a clutch
thanks

The flywheel (and it's a dual mass flywheel you'll need, or DMF) only needs changing if the old is worn out - it'll be making a noise for thousands of miles when it needs replacing. If yours isn't making a noise, no need to buy a new one, just put the money in a savings account and keep it until/if the noise starts.

personally, if the seller is unsure of what he is selling, i would steer clear. The 120 and 150 flywheels are different and not interchangeable. any reputable seller will have a part number for reference purposes, usually they sell LUK flywheels, which all have the part number on the box.

no mines making a right racket so need replacing ,its just that you see the f/wheels advertized saying they do 88kw & 110kw cars ,I know form asking I need the 110kw/150bhp one,so was just wondering if there is any numbers on the flywheel itself to let you know which is which
thanks
