What are you turbo guys running for oil restrictors?

 

I haven't done this yet, but need to. Alot of guys are either running nitrous jets or the function7 setup. You've probably already seen this, but just in case you haven't:

I am using the function 7 on my truck.

 

I made a .075 restrictor for mine.

 

Where did you put it?

 

I'm still running whatever is in the STS kit still. Is that bad?

 

I still have the check valve from the sts on the turbo, so I took a brass 1/8 NPT close nipple and filled it about 1/3 full of soder and drilled it out with a .075 drill bit. Then I put it between the check valve and the -4 inlet fitting on the turbo, using a 1/8 NPT coupler too. I would have used a N02 jet, but this was faster as I don't have a place around here to buy them.

 

I have told a few people to do that. Seems like the easiest way to do it.
Just braze the brass fitting closed and drill a smaller hole.

 

We use Nitrous jets. Choosing the right size can take time.The correct way is to put a oil pressure gauge at the turbo and get the recommended pressure which is ussually 30-35psi. I just go by the oil smoke out the exhaust. Ussually end up with a .051 to .072 depending on oil pressure at the engine.

 

we did the nitrous jet trick. started with .075 and still got smoke se we steped down to the next size. something like .69 but i am not sure of that.
