Kev...thank you for those links!! Top Geezer!! I was wondering.........

Firstly....I didn't realise the bore needed plating, however I have found someone who does Nikasil ...so no problem with that. Would the bore wear out quickly without it? Is it an alloy bore, coated as standard?

Secondly,

...on the Carillo site , the CR pistons are either 11:1, 12:1 or 12.5:1?? Not 11.5:1 ?????
Is the CR piston forged, and the others not? Is that why its dearer/better?

I have found a JE 103mm piston kit 11:1 (item no. 360083541989 on ebay.com) , he will send it carriage free to the UK at $171.99, and a top end gasket set for $68, about �155........I'm think I'm going to go for that..........

Thirdly, do you think a gain of 10-12 hp is on with this, over Standard, with my mods?
