hey all, so i decided to get into my IP on my 617 engine to remove the rack limiter and adjust some settings, and im just wondering what this little white plastic valve is for?



im also wondering if anyone has tried to make a new oil filter setup before? its just an idea as its gonna be kinda tight in the little mazda engine bay where this is going. im thinking a piece of 1/2" steel plate, tapped for the fittings from the aluminum, then run a remote filter head on the fender somewhere? shouldn't be to hard to tap into the line for a feed to the turbo, and a fitting for the pressure sender? im pretty good with fab work, and im sure it can be done, just wondering if anyone else has tried it?

just right over here with a couple hoses running out of it.
