Ok, so I've been looking at converting my boost lines to the hard plastic Polyurethane hose like pictured below on this K20 Motor:
I forsee one problem...my boost control solenoid. It is the one that came from Hiboost, that is made by Eaton. The plastic barbs off of it are considerably larger than my other vac/boost barbs in my engine bay. I looked on the Haltech website, and found that the solenoid they sell has 1/8 NPT-threaded ports (so I can put in my own barbs, or John Guest quick-connect fittings), but is is about $89!
I notice that this looks just like the AEM boost control solenoid that sells for $106!:
Damn, these things are HIGH!!
I did some digging on the internet, and found out that the solenoids are actually made by
MAC Valves, and sell for about $20. The only drawback is that they are built to order, and have a 4-week lead-time.
The part number is:
35A-AAA-DDEA-1BA (12.7 Watt, 12, volt)
They also have a 5.4 Watt, 12 volt solenoid:
35A-AAA-DDBA-1BA
Here is a good
place to get them for $26:

You need the 12 volt, 1/8 sized orifice.
