    Default Bigport REV limit..

    Just wondering what the experts recon is a realistic rev limit for a worked bigport with standard bottom end.??

    Currently set at 8000. But will be throwing in some big cams in the next few weeks witch will no doubt want the engine to spin a bit harder..

    And what fails.? Is it the bearing or the rods.


    Fairly new to 4a engines... And god there boggy down low.
    So used to cruisin round at idle every where in my dunnydore.
    But there still heella fun

    This is a BIGPORT clinton... from what I understand AUS limit is 7500, JDM is 7750.

    20v would have closer to what your suggesting Clinton...

    Clinton... I dare say something was amiss... It takes an awfull lot of reving to get to 8600 with a standard bigport..

    i don;t have a tacho on mine.. when I first got it running i thought it was reving its tits off untill my freind told me I'd only hit 6g. HAHA..

    So I set the limit at 8000 then tried to hit it.... Takes a bit...

    You can rev it to 8500 if you want, but obviosly that is over the stock ECU rev limit. I have heard several storys of failed conrods at 8500rpm. 8000 would be fairly safe.

    factory spec is 7750 for zenki. then though wound it back for kouki. most likely due to engine failures.

    i intended to set my rev limit at 8000. my motor does have cams and also uses a 101 bottom end. there just no power up there.
