I need to find a boost reference point for my '13 MCS and found this. Only problem it says its for an N14. Will it work with my N18 engine? If not, any ideas?

BSH boost tap

 

Google Forge Motorsport boost gauge adapter....they are about £25 but can also be found on eBay.
It fits under the air box where there is an existing takeoff point.

 

The BSH Dual Boost Tap will not work on an N18 engine, as the N18 engine does not have the head cover to throttle body PCV hose like the N14 engine does.

Forge, Alta and Cravenspeed have boost taps that will work on an N18 engine.

I believe the NM Engineering (Neuspeed) will work:

Yep, cerenkov is correct. NM, Alta, Craven all have similar adapters. If you are installing a mechanical gauge this will get it done. The real time data from the Manifold Air Pressure sensor (where this adapter is installed) is also available via obd2.
