Oversize Pistons 0.50mm

Hi Chaps,
I've just bought a used engine today and taken the barrels to S.E.P in Kegworth for assessment.  The verdict ?
I need a rebore "See what you pistons and rings you can get, preferably 0.50, but 0.25 would do".

I see David Silver do oversize piston sets at £48ish. Before I go down that road I just thought I'd ask, does anyone have a set they're willing to part with ?

Thanks
Steve

I know member andut recently had to go down the rebore route.
Might be worth checking with him to see where he got his parts from.
DS price for four piston kits is the best part of £200 with delivery and VAT, don't know whether you will find cheaper.

stevush:
Thanks Chris,
Yes, looking around last night I've seen a couple of sets all around the £200 mark, anyone got any experience regarding the quality of the pattern parts ?

It may work out cheaper to gat a big bore kit.  I saw one on fleabay a while ago for less than £200

Hi Steve,

I got oversize pistons from DS and so far all is well - As Mike says, a big bore kit would potentially be a cheaper option, but I didn't investigate suppliers or quality of kits etc - I didn't want to get involved in rejetting / dyno work that would be likely with cc increase.
