    Smile SOHC to DOHC (4G63)

    Hi!
    I'm going for this swap using a 4G63 SOHC turbo <Starion/JDM early Galant Turbo> block with a DOHC GVR4 head.
    What pistons will I need to use?
    Will the SOHC pistons fit and not have any clearance issues with the DOHC head and valves.
    Thanks.

    Is your car a RWD Starion/Conquest ??
    I have done a big port =VR4 Gallant twin cam head on a 6 bolt 63 block and stroked with a 64 100 mm crank It has Eagle rods & Wiseco pistons
    You MUST use DOHC pistons as they are fly cut so match the 4 valves
    Any other info you need please ask
