Recently, I was wondering what to do to protect my lines from turbo to MBC to Waste Gate/WG, from extreme heat they are exposed to. Especially the one around WG.

So with the help from 99_GST racer/who is moderator here/, I came out with simple, Not expensive and yet very well working solution:
- Stainless steel braided lines fron turbo to MBC to WG. Everyhting costs around $50 or so. I also called Mark Hallman from Hallman Boost controllers for some info and while I was there, I also replaced my MBC ball and spring, with heavier spring and ceramic ball. I highly recommend replacing the ball and spring, because it made a day and night difference to me in boost responce and may be even, reducing spool time a little.

So long story short, I got everything I needed and that includes:

-90* fitting - 1/8NPT to -4AN /this is the one that goes on the turbo/
-2 straight fittings 1/8 NPT to - 4AN/ both of them go into the boost controller and this is only for people who have Hallman MBC. Actually the threads on Hallman are 1/8 pipe STRAIGHT, but use the same pitch as 1/8 NPT and the only difference they are not tapered, but 1/8 NPT fittings work just great/.
-1 stainless steel line -4AN on both sides, 21" lenght
-1 stainless steel line -4AN to 10mm banjo fitting, the same size, as your TIAL banjo bolt /24" lenght/.

The rest is just simple work to get everything connected, even though I had to put a couple washers on the TIAL banjo bolt to get the hole right in the middle of the fitting, because they are both the same size 10mmx1, but the TIAL fitting is a little wider, than the fitting on the end of the stainless stee line.

So I got a quick ride around the block and everything works just perfect. With the NEW HEAVIER spring and ceramic ball my boost responce is awesome, the boost is steady 22PSI, so no complaints whatsoever.

The stainless steel lines I used are brake lines and you can get them at:Contact Allstar Performance

The fittings, I purchased locally, but this people at ALLSTAR have them in steel, so if you want alum fittings, you either call Summit, or ANplumbing.com.

If you have some more questions, don't hesitate to ask, the only problem is I have time only once a day to respond/around 1-2PM EST/. Thanks for your time, Andy.

Very nice. I have been thinking about doing this with all my vacuum/boost lines.
 
Looks good, Andy.

And thanks for the heads up of what boost controller you're using. My search is over!
I'm awaiting a call-back from mark, and I'll have one of those on the way.

Also, those guys at Allstar Performance can also sell you aluminum AN fittings from Aeroquip, XRP, Earls, and Russel, so there's no need to shop elsewhere.
 
Just to give you another alternative boost controller...the TurboSmart manual boost controller accepts -AN fittings as well, and works flawlessly, and is reasonably priced.

I hope, that may be someone with a JOE P MBC, will step up and let us know how AN fittings'll fit on it, so we cover the 3 most common types MBC.

Thanks in advance, Andy.
 
Andy, you just made this impeccably easy. I have a SBR MBC so I need to figure out what the thread size is on it to see if I can get an adapter for the ports, but I believe it shouldn't be too hard to figure that out. Only problem I see for me is that my boost source is going to be on the intercooler pipe so I'll have to see how that turns out. But thank you very much for this information :thumb:.
 
Glad to hear that...
Just weld a nice bung on the IC pipe, don't do it half way/ just drilling and tapping the pipe, it is going to leak/. Since you are in Cali, just call ANplumbing.com and get your fitting, unless you have some local store to pick it up from.
 
Looks great.

I will also be doing this with all my vacuum/boost lines.
 
This should work with the Hallman ES MBC right? :talon:

Yes, it will. You just buy two 1/8 NPT to -4AN fittings, besides one on the turbo and you are good to go. However, I strongly suggest using male fitting on top of the WG/Tial/ and -4AN female hose instead the banjo fitting, which is still works, but it has to be spased on both sides with few washers/crush washers to make sure the HOLE is exactly in the middle.

However ANplumbing.com, sells straight/only/fitting in size; 10mmx1.0 pitch to -4 AN. 10mmx 1.0 pitch is the size on top Tial WG and BOV ...

-Lockness Monster, thaks.
