michael Posted June 19, 2006 Share Posted June 19, 2006 Am I right in thinking that the stud pattern on the UK manifold is different to the UK one? Secondly is there any reason why I couldn't put a J-Spec head onto a UK block? Obviously I'd swap things like cams over but would I be losing / gaining anything else that I need to consider?

Alex Posted June 19, 2006 Share Posted June 19, 2006 Am I right in thinking that the stud pattern on the UK manifold is different to the UK one? No they are identical ...but the j-spec is different to the UK, but not at the block end, just the turbo end. Secondly is there any reason why I couldn't put a J-Spec head onto a UK block? Obviously I'd swap things like cams over but would I be losing / gaining anything else that I need to consider? Don't think this will cause any issue's.

That's good news then I knew the other end was an 'issue' but I can deal with that, for some reason I thought the stud pattern on the manifold was slightly different as well. Don't think this will cause any issue's. That makes life easier as well then Quote Link to comment Share on other sites More sharing options...

michael Posted June 19, 2006 Author Share Posted June 19, 2006 No serious issues to report I have the valve stem seals to do and the turbo kit I'm fitting is from a J-Spec - I'm just thinking of getting a built head and was wondering if it mattered if it was from a UK or a J to start with. Just doing some basic homework before parting with any money Quote Link to comment Share on other sites More sharing options...
