I'll be adding a boost controller shortly to the 941. However, I do not want to butcher the stock wastegate actuator line, given their rarity. Does anyone know where I can find metric to hose barb fittings? The wastegate actuator line has M12x1.5 threads, but I can't find any hose barb fittings with metric threads, only SAE. Ideas?

Maybe an adapter bushing from M12 1.5 to something common sae like shown on this website http://www.egauges.com/vdo_indA.asp?PN=R7962

Good luck, i searched all over for the female fitting to adapt a barb fitting the charge tube side of the actuator line..

Even has an autometer part number :/ which means I can order it from my local parts store.

Thanks Min! I ordered one each of the M12x1.5-to-1/8NPT and M14x1.5-to-1/8NPT bushings from egauges.com. There is actually a male-to-male M14-to-M12 reducer between the actuator line and the charge tube, so both sizes are needed. I'll then pick up some cheap 1/8" NPT to 1/4" hose barb fittings from the local hardware.

I believe an alternative is to pull the pressure signal from the over-boost switch port on the charge tube to the top port of the waste gate. Just work out a 'T' arrangement at that port.

Yep that's easy way to do it and parts are at every hardware store....

My buddy did it this way. Worked great. As Paul says, Easy.

I cut into wastegate line, which is what you're trying to avoid. It has worked well for me.

Cheers, Brian

I've done it both ways but kind of like leaving the waste gate signal line intact now a days, particularly since the alternative is easy.

You should consider the size of the pipe when you are going to add a boost controller. And you might need an adapter bushing for the controller.

found a way to have a NA fuel hoose fit...but looks stupid with that extra hoose....so giving the fact that i have spare WG line...i decided to cut one and put in the boost controller.

Plus..there is a company here that can re-make that hoose as new for cheap.
