can anybody recommend a company who is capable/has knowledge of reboring a 5L 928 block to 6L?
anywhere in the UK will do as long as they have done them before and are reliable.
thanks in advance
Phil

Hi Phil :)

I am not sure there is ANYONE in the Uk who can do it... as the problem is with the Alusil/Nikasil bore coating....

Try giving Paul Anderson a ring and asking, if anyone knows, he will...

All the best Brett :)

Can you take it to 5.4 ltr with the crank, etc. from the GTS? Or was the GTS bored bigger?

Yes your right Lee the bore is the same just a longer stroke,I believe the 6L is just an even longer stroke,there are kits from the states but Id go for the twin turbo option from www.kuhnperformance.com

Don't give up so quickly. Brett told you to phone Paul Anderson, he might know someone. There might be oversized rings out there? How bad is the scoring? Have you got pictures?
