Hello. Im planning to replace my current 550cc prim injectors for 850cc injectors. I understand that the fuel rail will need to be modified. Will i have to machine the LIM as well ? Also can i use the same injectors as used in the secondary rail?. I have spare set.



Or does anybody have a guide to doing this job?

there is a thread started by treceb, and its still active about this subject

Well the primary injectors are attached to the engine, not the LIM so no modifying the LIM. I have used the stock 850cc injectors in the primary injector rail. To get it to work you have to shave appx. 2mm of aluminum off the top of the rail. You'll need a fuel computer to change the injectors sizes to match the 850cc.

Thanks guys. All seems fair enough to me. Finally some extra fuel is on its way ! :-)
