oil fitting
 

ok i bought the fitting from sunpro to 1/8bsp to 1/8npt but my question is the whole in it is very small, should i drill it out? if so to what size?

if the fitting works, use it and don't drill it out. if it doesn't, 1/8 npt is a good size to use if you can't find anything else that will work.

it screws in the block perfect but the whole in the middle where the oil flows through is only like a 1/8 of an inch? seams to small for me?

Re:oil fitting
 

Have you ever heard of anyone drilling it out? I havn't, so just leave it as is. The oil pressure that comes out of that hole makes up for it's small size.

have you used one? i know if i was to buy a 1/8 npt nipple that the hole would be alot bigger than this fitting is. im sure the hole is only that big because its made for a oil pressure guage. i just dont want my turbo to burn up.

it'll be fine. if you have too large diameter you will get too much oil and it will push past your seals and into exhuast/compressor and ruin the seals. it won't be able to flow out quick enough. the hole down in the oil inlet of my turbo is even smaller and it gets plenty of oil.
