    Is it true.....

    Been reading some stuff on Mig about the Z20let and some people are saying that it can really only take 250bhp then after that the turbo (i know this is true), pistons cause the engine does not have oil spary bars, gearbox, clutch can't take it. If this true?

    Partially. Turbos good for 250-260bhp, internals are ok to around 290-300 as a rough estimate. Gearbox is pretty strong IIRC, but clutches can be weak - especially the newer ones !

    eh???

    Torque is the figure you should be looking at when discussing gearboxes and clutches.

    The question was specifically about bhp, hence the answer !

    Torque wise, 270lb/ft + on the newer clutches is asking for trouble

    The "eh" was in reference to me not being able to make proper sense of what he was saying. Some better punctuation would have made it easier to understand.

    Sorry sometimes have to type fast at work.

    I was just reading some posts on mig about the Z20LET. A few people were saying that it really cannot take anymore than 250bhp. After this the turbo cannot take it (which i already know), pistons melt due to no oil spray bars, gearbox and clutch also cannot take anymore than that.

    Was just wondering the truth in this as i see a few members pushing over 270bhp and 1 or 2 nearer the 300 mark!
