So I bought a generic t3 ss braided oil line kit. Both the turbo sides obviously bolt up fine. I have a 95 block so I'm lucky enough to have the high pressure oil feed port. My question is what adapter should I run to get what appears to be a m10, I might be wrong. It looks like its the same dimensions but with a finer thread. I read on the wiki I should use the m10x 1.5 to -4an? I know its probably impossible to tell without measurements but ill see what I can dig up. I think deezums used a similar setup

 

alright so it says its a 1/8 npt to 4an. So would a m10 x 1.5 to 1/8 npt adapter work?

No?

 

I use a m10x1.5 to 4an adapter, then I use a 4AN brake line from there, to a T3 4AN inlet restriction plate. You need a new 10mm copper crush washer, too.

Don't buy aluminum adapters. Throw the dumbass NPT ebay garbage away.

Or do what I did and break that fitting you found off in the block.

 

Thanks, I'd only like to drill and tap my engine once
