I seriously do not think one should use the nipple b/t the two oil injectors for fuel pressure regulator regulation. I could of course be wrong.

Only way I know to be sure is to put a boost gauge on that line and see what the max boost coming off that nipple is. It goes to the fuel injector air bleeds.

the line between the 2 oil injectors goes to the side of the dynamic chamber, the vac feed for the fpr comes off of the dc also.

common you guys are always asking about vac problems well here is one of the most simplist vac system you can get. less vac lines less change for a leak.

can you do that and still pass emisisons testing?

EDIT: is the air bypass valve (BOV) vac line going into the BAC or into the nipple just under it?


EDIT II: nm there isnt a vac line on the BAC

So have you tested this setup or is it just a theory? I'm looking for a real simple setup to use for mine.

Did yours end up working correctly?

Also, what is the purpose of the oil catch can?

well it runs

to catch oil comming from the oil fill tube. stop it from being sucked into the turbo.

Ah, I didn't notice it went to the oil filler neck. Is it possible to just cap that line off instead?
And I guess running is better than where I'm at right now...

I have 2 vac lines total in my n/a, works very nicely. Not much chance for a leak with 2 vac lines and every other nipple capped

Am I missing something? I never saw a diagram here. The links to the diagrams at 1300cc are gone, too. :P Does anyone still have this lying around? (Yes, I know it's old)

Sweet, that may have something to do with it. I never really distinguished between metered air and vacuum, so it's possible I've got some weirdness going on there. :P It's just weird that it would run for hours before I fixed my exhaust leak, and now it won't even idle.
