GRM miata folks: does anyone have a jackson racing M45 supercharger kit for a NB miata on hand that could get some dimensions on the mounting brackets? Specifically the triangular bracket which mounts to the exhaust manifold studs, and the rectangular support brace, circled in red below.
I'm transferring over an M45 from a 1.6 NA onto an NB for my rallycross project, and I'll need to machine these brackets for mounting. Moss Miata no longer carries any Jackson Racing parts, and I'd much rather try to reproduce these from the kit measurements before trying to mock up the brackets from scratch.

I don't have access to one, but Gary at Track Dog Racing may be able to help. Also, that bracket is probably the same on a 1.8 NA.
Good idea! I'll reach out.
I've got a M45 kit that came off of an NB Miata. I can grab the measurements of those brackets at lunch for you.
I don't own a Miata at all, but for the peanut gallery, would you mind posting the measurements once you have them?
Otherwise this thread is gonna lead to false hope weve all encountered for someone else with the same problem
I thought the same thing, here is what CollectingJunk sent me. I plan to model it in CAD, 3D print in PLA for mockup and then either weld up or send for CNC. I can post up a CAD drawing when I know it works, but not sure if that is infringing on any patents or not-so ethical (these parts are all NLA, so I would think not). Bracket thickness is 0.25".
Really, these two brackets also need the "main" bracket that bolts to the supercharger, it looks like they used the same "main bracket" for all the kits and NA 1.6, NA 1.8, and NB have different supporting brackets.
Future GRM forum visitor says thank you.
