    Re: ebay special gt28

    yeah i thort it might be too big , do you think coming in at 5k is right i just didnt know if it might be anything else ?
    if so is there anything we could do to get it to come in earlyer ? or do you think it might be best to get rid and get somthing smaller ?
    thanks

    We need to know the engine spec first, specifically what cam it's running?

    For good response but, still a boost capability upgrade you need to look at a T25/T2 hybrid (T2 turbine housing) and for even more boost but still reasonably responsive you should have a look at a full T25 with a 0.49 turbine housing.

    The T25/T2 will work ok with the STD cam but you will need to change the cam to get the most out of the full T25.

    5000rpm is about right for an 0.64ar turbine. If he swaps that for an 0.49ar from a Rover tomcat, etc then it will be more like 4000rpm.
