So I have a old-school trust fmic. I have never used a front mount before, so here goes. First off, why would there be two blow off valves? There is one small one and one large one. The other question is about an injector. There are two spots for them, one blocked off, the other has an injector. And finally, is it normal for there to be oil in the intercooler pipes?

Thanks for the answers.

2 blowoff valves because some ricers think it's cool? Maybe a small to quickly vent pressure and the large one for volume... I don't know.

The injector question is fuzzy. Are you saying the FMIC kit has injector bungs? If so, you won't be able to use them unless you have another injector driver, and it's more hassle than it's worth.

Oil in the IC sadly is about par for the course, but not good. The car that came off has a turbo that pooped itself.

One is a blow-off valve one is a pop-off valve

The injector bungs is for injectors running on an AIC controller (optional)
oil in the line is normal...specially since its steel and can rust

Here are a couple pictures. You can see the two different hks blow off valves and the injector. So, the injector can stay on until I have a block off plate for it? As far as the two blow off valves, I am still running stock turbo, I am not sure what to do with these. Should I change any of it?

And should I clean out the old oil in the piping?

Yer it wont hurt, but it would be a good idea to get an oil catch can hooked up so you dont get anymore oil in the cooler or intaking piping. Most factory cars pump the blow by into the intake hence the oil you have.

So why would one blowoff valve have two nipples? Posting two more pictures. The larger blowoff valve has two nipples while the smaller only has one, which is what I am used to. They are also located in different areas. From the pictures above you can see the larger blowoff valve, which is on the pipe going from the intercooler into the manifold. The smaller blowoff valve comes right out of the turbo and goes into the intercooler. Pretty sure I should tee the vacuum line into the smaller one from the boost sensor into the manifold. What should I do with the larger one? If I don't have a use for it I will just pull it off and put a block off plate there. They are both HKS units.
