Hey guys, I'm currently Putting together an MSM turbo for my NB8B VVT mx5 and im wondering if theres a fitting for the boost pressure source on the compressor housing or if anyone knows what the thread size is?

Thanks!

 

There is not. Source it from the ic piping

 

ohh, i though this was the bung for it?



Thanks!

 

nope
msm sources from the tb elbow

 

I see, do you ave any idea what that thread shown is for sir?

 

I'd have to double check, but I think it's to secure one of the coolant lines

 

I would have to say it is for a coolant line clamp. Sorry this is the best pic I had. You can't see that mounting point in the picture, but the only thing that runs close to it is the coolant line. I know I did not use it with my MSM turbo install so I am sure it does not pass any air. Before looking at the pictures I thought it was a mounting point for the heatshield, but those are only on the hotside parts.
