Smim

[GST_CSF]

I was wondering on your SMIM can you also make them with threaded holes on the runners for a direct port nitrous system? If so how much more do you estimate that would cost? thanks

I don't want to answer for them but i'm sure they will for a little more cost, but just give them a call I'm sure they will help you out.

I believe on there website it says 25 extra.
I'm not sure if thats with them welding it in though. Sorry.

The bungs welded on to be used with nitrous costs $25 more, however they are only center drilled. Final correct size drilling and tapping is to be done by the end user because you don't want to go all the way through with the taps when using npt thread fittings. Some people may also need to drill the holes different sizes for other applications (as in water injection), or they're not ready to use nitrous just yet but will in the future so those are some other reasons they'e not predrilled or tapped.

Right. Work on your end for your specific needs is pretty low. Little time with a drill and a tap. ;)
