Hell I dont remember.
I think its 12x1.25

 

Go to anplumbing.com enter the site in the first column it says steel, click scroll almost all the way down. there is a -3 12mmx1 fitting. hope this helps!

 

See that isnt gonna work.

 

Damn that turbo is a pain! No restrictors, no fittings.
If you can run it off your pressure switch you shoul be ok though. 72psi is max the turbo can see. I have a gauge mounted with my pressure switch and feed line and it never sees 80 psi well exept during cold start. When vtec kicks pressure drops at the switch to account for the vtec solenoid opening. If you can't find the right fitting or restrictor this is gonna be your best bet!

 

I went to a diesel shop and took my feed line and turbo....country boy took the one fitting that threaded into turbo with the o-ring...found another that fit the feed line..went to the shop area and back in five minutes with the hybrid fitting..he cut the two in half and brazed them together..beautifully, I might add. No restrictor tho..2 years now.
The orifices in the fittings maybe..but they're pretty big.
I asked him about a restrictor and he looked at me funny.
I was already pushing my luck by telling them it was going on a Honda. Turbo Dodges are kind of a religious experience here.
He said it needed all the oil it could get, lol. I've seen that info from the manual tho. I have a gsr oil pump..no pressure gauge, so

 

you just bumped A 4 YEAR OLD THREAD.....

 

Wow, I have since sold this monster turbo and im in the process of building a K series.
