    Default Billet Cranks

    Having a read on 205 Drivers and I've found that the cranks in 306 DTurbos had an 88mm billet crank. I know the XU9 Mi engines had an 88mm crank but was it also billet? The other thing is, are there any 1.9 diesels here in Aus? What are the chances of getting one or will it be a UK Ebay import job?

    Cheers

    It won't be billet. Forged is what they'll be refering to.
    Have a look at post #42 in Cam85's build thread. There's a pic that will show you how to identify the difference between a cast and a forged crank.

    Obviously the forged one is better for the diesel as they wouldn't have fitted it otherwise, don't know if there are any disadvantages for petrol/high revs.
    Plenty of 1.9 diesels around, 306/405.
    Billet crank is machined up from a billet of steel in low volume.
    I have one of these in a 306 1.8 XU7 engine, now out to 2 litres.
    $4000 worth, I was fortunate to be able to pick it up in a hail damaged car for a lot less.
