RobSheffield Posted July 25, 2009 Share Posted July 25, 2009 I want to fit larger injectors into the existing collets i had welded into my lower runners. Trouble is nobody seems to be able to confirm its possible. Are the Bosch 1000cc bottom collets similar in size to the Siemens? Quote Link to comment Share on other sites More sharing options...

Trouble is nobody seems to be able to confirm its possible. Are the Bosch 1000cc bottom collets similar in size to the Siemens? When looking at aftermarket injectors from such sources, they didn't tend to specify the nose diameter so I'm assuming that's because they are all a standard size Nothing definitive though, sorry. 1000cc? Got plans, sir? -Ian Quote Link to comment Share on other sites More sharing options...
dandan Posted July 25, 2009 Share Posted July 25, 2009 Almost all Siemens and Bosch will be the so called 14mm type....referred to as "domestic" in the US. Rob - if you're looking for a set of the modified Bosch 1000cc ones with the special top caps then pm me as I'm considering ordering a set - we may get some discount.

Ian C Posted July 26, 2009 Share Posted July 26, 2009 BTW if you need a new set of lower intake runners to fit different collets to drop me a line, I think I've got two spare ones for some reason. Quote Link to comment Share on other sites More sharing options...
