Boost solenoid issues

Boost solenoid plumbing

Hi. Sorry I know that this will have been covered many time but I'm struggling to find any information and some of old post pics not working... also not getting any help from the UK sites.

I have a R33 1995 gtst.

I have a hdi front mount intercooler fitted hybrid turbo with the actuator that plumbs back to the turbo itself. Im taking it to local tuner for remap soon but need to get it running on standard ecu and boost solenoid so I can get a mot before remap.

My problem is I'm not sure where to plumb in the boost solenoid pipes. The hdi intercooler pipe doesn't have a vacuum nipple and as said above the turbo actuator pipe goes back into the turbo. Help please

You can use the fitting on the turbo outlet as the boost (not vacuum) source. Is the bleed line to the BOV return hose still connected?

If you have the original pipes there was a restrictor in one ( think it was the boost supply pipe). If you haven't got it don't worry for a temporary set-up... you will just make a little less boost.

The supply goes to the T and the other side of the T goes to the actuator. The third leg of the T goes to the boost solenoid (doesn't matter which connection) and the other connection on the boost solenoid goes to the Bov return.

Hi. Thanks for your reply.

All hoses are off as stripped down to fit new turbo. Doesn't need to boost much just as long as it runs ok for mot.

Going to have a play with it this weekend hopefully but depending on weather and as you probably know uk weather is never good
