    Yep, peak power on the 318is is usually around 6k rpm.

The car had lost NO bhp over its lifetime and the dyno guy said most MR2's he had tested were the same.

    Just use my 318is for commuting - there is no point chasing power gains out of it! lol
    Don't quite see how that is useful to the OP? Anyway, there is absolutely no point in comparing rolling road figures in that way. The only worthwhile way of doing it is to run it on the same rollers on the same day.

    The M42 is fantastic engine and there are plenty of ways of getting more power out of them. Got a couple of mates with 1.9 conversions pushing out 160-170bhp which didn't cost them much. It's also a popular engine for bolting a supercharger on or going for a 2.1 conversion. Loads of people are doing lots of fun things to them!

    Ian S and Zircon - thankyou for your replies, and I appreciate what you are both saying - but, im not looking to tune the engine as such.

    Am just looking to get her back to the ~140bhp she left the factory with.

    Ok cheers mate, interesting stuff, ultrasonic cleaning, pretty clever too likes.

    Nah don't think so mate - car has a full stainless exhaust, and compression is even, but very high, talking ~225psi on all cylinders. Think maybe the head has been skimmed. Any mods have been done by previous owners, so I don't know the extent of whats been done...

    (One other thing - the peak torque was basically spot on - 125lb.ft@4685 (meant to be 129@4500), so its not all doom and gloom)...

    Was just saying that the M42 does not seem to be a particularly good engine for output or keeping its power and that it is a shame when you compare it against its competition.

    Let us know how you get on in trying to get the power back - would be great to know what is holding it back........
