    i got scared when i seen these i no what has coursed this at one point in it life the timming belt has snapped and the valves have hit the pistons.

    im now scared that i carnt use the pistons and is more money to fork out can anyone shed some light please if they would be ok or not .

    Marks on the pistons will be fine once you have used a bit of wet and dry to remove the sharp edges mates...

    As said i'll pop round to have a look

    I'll have my glaze buster/hone then as i'm over your way this weekend ( Saturday at about 10.30 ish )

    Make sure the pistons are out by then, it would help if you can remove the oil jets too

    can I be slightly controversial here and suggest that as your pistons have had a whack anyway, you sack off the ****ty low comp pistons and buy Danis AGU pistons he's been trying to sell for ages?

    Everyone knows that all the best hybrid's are large port AND high comp.

    Low comp seems favourable when big turbo's are used, and you can use more boost to get the power up instead of timing, but on a little hybrid that's on it's limits making 22psi + it seems that ALL the higher 9.5:1 engine perform better than an equivalent spec 9:1 engine.

    I'm certainly sticking with my AGU pistons despite the option of fitting BAM ones to reduce CR.

    Don't see why Dani! Everyone knows 9:1 s3 stuff is crap. Welly has 450bhp and agu 9.5 pistons, tufty has ~400bhp and Ibiza 9.5 cr pistons, even the immense badger wagon with its mental ~600bhp has 9.25:1 cr, so why anyone would stick with s3 pistons and 9:1 is beyond me!

    Yeah think I made the mistake of putting 8.5cr pistons in my current block :(

    Have always wondered what my turb could do with decent supporting mods and higher comp?

    I have around 8.5:1 but i do have 2067cc anyway so that does help as i still plan to run about 35 psi with the GTX3076. At 35 psi its working at its most efficient at that pressure anyway.

    I don't think it's such an issue with a massive turbo, as with the lower CR you just run a bit more boost to reach the same figures, and it's all well within what the turbo can do.

    On a little hybrid, which is very compressor heavy, and limited by it's hot side, you don't have that option to add another 2-3psi of boost to compensate for the lower CR, as that just pushes it beyond it's efficiency and generates more heat.

    For that reason, it seems sensible to me that small framed turbo's like a ko4 or ko4 hybrid would benefit from a slightly higher CR, yet the massive stuff like GT30's and the like can stick to more old school principles.

    It'll always be more lively off boost with higher CR too

    hi guys

    ye bill the turbo is off and been sent to cr for them to look at the air line crack then it will be going back on and hopfully the spec
    of what it is now is the highest to achieve best power gains. ill reseal the bung too.

    as for the pistons guys im about to buy them and just want to no weather this is the right thing to do instead of keeping the amk pistons
    dont no much about them but JBS told me theres no differance in either and the AMK ones are better stuck.com
