Hey Pete, few options here

As we discussed at DGRR you could weld up the banjo bolt and drill a .060" hole in the banjo bolt.

There are some fittings that you can purchase that allows you to convert the top of the turbo to a -4 fitting and easily allow you to change fitting sizes, you will need to build a new feed line but that is really minimal effort. Hell, Verocious can actually build a line for you when you order parts.

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.
