I mentioned that idea when I talked to Bryan @ BNR; he said it would work, but for long term durability, he recommended putting the restriction as close to the turbo as possible. Reason is on cold start up, you have a volume of piping to pressurize. While the turbo won't be making any boost at that point, it will start spinning as soon as there is exhaust pressure, and if the restriction is further downstream in the oil line, you'll run a small risk that the turbo can start up a bit dry. That plus I can't weld convinced me I should stick the restriction as close to the turbo as possible.

Something like this from Verocious Motorsports - http://www.verociousmotorsports.com/...e-1-8-NPT.html
and couple it with something like this - http://www.verociousmotorsports.com/...r-Fitting.html
that allows you to easily swap out the restrictor size without breaking the gasket seal on top of the turbo. That's probably the most elegant way to go about it. I have seen plenty of people take a soda can, cut it out, and punch a .060" hole in it for a restrictor.... they almost always leak for one reason or another.
I vote the first or second approach. Second is the easiest for swapping different restrictors. |
Yup, I've seen the Verocious stuff, and I really like the part with the changable restrictor jets. BUT some of those parts may take at least a few days to get in stock according to Verocious. So I figured the plate option will allow me to do a bit of trial & error testing this weekend at virtually zero cost, other than my time and the extra gaskets I already have on hand. The 1/16" AL bar stock I have isn't quite as flimsy as a soda can, so I don't think it will leak
