    S52 engine for e30 race car

    My build is on the way
    S50 intake
    Schrick valves & spring
    Sunbelt stage 3 made for hydro lifters
    Knife edge crank
    10;5;1 JE piston, Will run 94 fuel
    Cometic head gasket
    Pauter rod
    Red top Bosch injector
    PS delete
    Vanos rebuild (seals and bearing)
    Lite pulley (alternator and water pump)
    Jb flywheel
    All new internal

    What would be the limit rpm for the hydro lifters
    Should I sell the cam and buy solid lifters cams?
    I have a set of solid lifters ready to use

    Will run Adaptronic ECU

    Thank

    I think the RPM limit with hydraulic lifters is ~ 7000, not a lot higher with solid lifters.

    Sounds like you are looking to go S54.
