    ok so Im doing a rebuild. Im putting in these .020 wiseco pistons and eagle rods. When i put the first piston in it just didnt look good. need some help i put some picks up.:confused:

    to me it looks like the piston is short. but could it be because of the 9:0:1 comp/ratio

    what about it didn't look right? and you obviously bored the cylinder over .20 correct?

    Stroker pistons on a standard setup can look like that. What block is that? What crank? And, what are the part numbers of the rods, and pistons?

    Those are stroker pistons, the pin bore is 6mm higher than a regular piston.

    Go to a pick n pull, there are tons of 2.4's there. Get your crank for $40, then get it polished.

    88mm or 100mm and would that 2.4l crankshaft fit on a 4g63

    The one you have is 88mm, which is causing the piston to sit 6mm lower at tdc. You need a 100mm crank from a 2.4. They are easy to find. The 12mm longer stroke will raise the piston 6mm in the bore at tdc.

    As everyone said you either need to get a 100mm crank (to do this you will need to do some extra machining to the block because the larger crank will hit them) and make your engine a 2.3L, or you can get rid of these pistons and buy the proper ones for a 0.020" over 2.0L engine.

    not everyone needs to machine the block Ive personally never done that but if you have any doubts you can file it down very easily yourself.
    Onelove Your options are returning the pistons you have to get normal non stroker pistons or like everyone else is telling you just pop in the 100mm 4g64 crank.

    Since your car is a FWD I would prefer to not build a stroker as the biggest gain you will get is more torque lower in the RPM range which means more burnouts for you. It will still be drivable if you get the 4G64 crank I would just opt to change pistons and keep it a 2.0 if it were my car. It will be more FWD friendly and easier to tune.

    The main caps need to be notched to clear the 100MM throw and areas of the block needs slight clearance work. I'd recommend sticking with the 88mm crank and get the right pistons.
