so i recently turboed my car but the turbo smokes. i took off the oil line and didnt see a oil restrictor. so i tried to match a fitting to it but the threads arent 1/8 npt. it looks almost like a course thread. what other sizes are there on turbos besides 1/8 npt? AN? is there a fitting i could bolt onto the turbo to turn the feed into a 1/8 npt. or can i put the oil restrictor any place before the turbo?

thanks

i used a nitrous nozzle as an oil restrictor

ebay turbo i dont have much info on the turbo. the previous owner just stretched a 1/8 npt in to fit. i dont have any nitrous jets to use. mine doesnt seem as pointed as my 3an fitting. im using a 4an line i think

i dont understand. the previous owner used a 1/8npt fitting? you cant just make a fitting work. either it fits or it doesnt.

take the turbo to a hardware store and see if you can match something up. its gotta be npt threads or maybe something metric. highly doubt that its AN.

also are there bolts for an inlet flange? you could get something like this

he just screwed a 1/8 npt in, stretching the threads. you can see the two different thread when you take the fitting off the turbo. he also welded the turbo to the manifold so alittle hard. full ghetto rig. this is my only car so i cant take off the fitting unless i take off the turbo

it does have bolt holes. thank you that was exactly what i was looking for.
