Anyone know where I can find a compression gauge for a turbo fit engine?

edit: something like this:

I don't think anyone makes one for a turbo plug.

Get this item from Mcmaster.com 3847K13 it cost like $9 and in any machine shop somebody will make you adapter from 1/8 NPT to M8X0.5 with taper on the end 30 degrees for turbo plug connection type. If you need drawings for adapter, let me know and I will make one for you.

Here is detailed drawing for adapter ( I hope I didn't miss anything)
You can just print out from pic and give to machime shop and you will have pressuer gauge for Turbo Head button. Make sure to tell to machine shop all sizes in metric beside internal thread for gauge connector.

Wow, thank you EdwardN. Now that's what I call a great answer . I'll take this stuff to a local shop and see what happens.

Thanks again.

Well, I am not really looking anything, just the guy asked where he can get compreesion gauge for turbo head and somebody reply nobody make it, so I open McMaster catalog, found the gauge which has the same range as it was referenced to Tower Hobbies item and made drawing for adapter between gauge and turbo head.
I honestly don't personaly believe in compression gauge because compression sealing depend on piston material properties and it might have not good sealing while it is cold and get better sealing when it will come to working temperature-so it is questionble. In the mean time, pressure on the guage will be different due to the different volume of the adapter from one design to another. What I will suggest (if anybody really want to have compresstion gauge) get one ( buy or make) and then take new engine, measure it and this will be your ball park number which you will be using as reference for all measurments in future.
