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

    • The car remains in paint jail. I am now pretty convinced that the whole "RB25 Airboxes are kinda limiting to ~300kw" could be a thing. Also saw a good video from Engine Masters: (Sorry for FB link) (https://www.facebook.com/watch/?ref=search&v=761771519471924&external_log_id=c10bcbb6-2c39-4ff3-9240-287e9921fde6&q=Cold Air Considerations) Where they tested Pod Filter sizes and kept adding bends to a LS3 on an Engine Dyno to find if bends caused power loss. It's a good video worth watching - They did lose ~25hp from making an intake which had 3x90's and a 120 degree. They only lost maybe 1hp with a basic 90. I feel that by sealing up my airbox I have: 1) Created the same restriction a stock airbox would have. 2) Created a very convoluted set of intake 'pipes' by forcing all the air through the ducts. So I am pretty confident I'll be going full circle and have a huge hot air intake pod and actually see a benefit. The air does *not* stay hot once it gets flowing, aided by the ducts, and the pod can then pull air from anywhere. All the posts of yore talk about the stock airbox costing 10-15kw at 300kw+ but you know what? I f**king would very much like that 10-15kw and I remember my own pod filter in engine bay experiences. Turns out the GTT Reo and Headlight brackets really don't allow you to mount GTR items, no matter what the internet says. Various brackets have had to be made up to actually make it fit right for the front bar. Also some idiot mounted a 3L Accusump right where the bumper wants to go, so that has had to be 'relocated' To where, I am still not sure, but it's supposedly mounted in the pictures and I can't see it.
    • Sounds like the oil pressure light is wired into the oil temp sensor... As it warms up, resistance on temp sensor reduces, hence more current can flow and the dash light gets brighter.
    • Got the front subframe and suspension in.    
    • If it's cold in summer, then no issue. If it's cutting out every few seconds and you're not reaching your target temp, then there's an issue. One could be the pressure switch and the other issue could be the temp probe inside the evaporator.
