as explained above. obviously you dont know the answer so is there anyone else out there that knows a bit about these systems.

i was looking for this once also, everywhere just said "the cas is sealed and unserviceable".. after alot of ****ing around i did find some one in Ireland that mods them for some reason and he has the info on his site.. sorry thats all i can tell you i didnt save the link.

anyone able to help me on this one?????? Thanks

Talk to Rick at efi performance, they were running one of these on an RB30 cant remember if it was 20 or 25 but they will definately be able to help you.
