My new LEAKPROOF WG lines

[booostedGSX]

Thanks a lot! This might be a sprng project for me.

Hey Andy, is it possible to use a straight fitting on the side of the tial w/g? Looks great guys.

Yes, it is. Depends on where the WG is located. If it is off O2 housing, or at the collector of the manifold,should be OK. In my case wiht ERL exhaust manifold and placement/location of WG it might be a little tight, but probably still will fit, especially if you use 90* fitting on the stainlees steel line.

As well, you can use a -4AN banjo fitting on the wastegate and BOV to use straight hose fittings.

Here is an example of the fitting required:
Pegasus - 4AN to 3/8 (10mm) Banjo Brake Adapter

^^^ That's the same banjos I use on the side ports of my gates.

Ordered all my stuff this evening. Followed your advice given in post #20 and #25. So I have a bung welded onto my ETS pipes that I will be putting a 1/8NPT to -4AN fitting on there and making sure it doesn't leak .

Supplies ordered:
-x3 1/8NPT to -4AN
-x1 10mm x1.0 to -4AN (for the Tial)
-x2 24" -4AN to -4AN(One end straight, the other a 90 degree angle)

Looking forward to putting it all together.

 

[andy4g63]

Good, hope you get it sooner.

I have a question for those of you who have done this mod. How are you guys eliminating your MBC (and for some of you, your BOV) for your BLT's?

 

[andy4g63]

^^^ I don't think you have to eliminate, at least not in mine opinion. I have Hallman MBC and there is a small bleeder hole on the OUTLET nipple of MBC. I did a BLT, like 3 weeks ago and did not eliminate anything. It was blowing a little air from that bleeder hole, but as soon you put your finger on it, it will stop. As far as BOV was concerned, during the BLT I did, I didn't notice anything and it wasn't opening either, so I was able to finish my BLT without worries.

Just a word of advice for anyone wanting to do this. When you order the fittings for the tial (10mm x 1.00), make sure you look for one that has the shallowest depth. I just pulled mine out today and noticed that it was going deep enough to interfere with the diaphram of the wastegate and cause funny boost controlling issues. A lot of the time, you will probably have to shim it out. Or if you have access to a layth that would work best. Just make sure your threads are clean when you finish chopping it.

Oh well, time to build it better and stronger then I got it haha

Extreme PSI sells fiiting-straight/10X1 to -4 AN.

We have done something similar using all pushlock and plastic hose. The fittings fit perfect in the hallmans BC. I'll get some pics from the shop and post them up tonite. We used the same stuff you use but we swapped it out because the plastic line is cheaper and the quick disconnect make it much easier to install and remove. Its also a lot thinner. Just another option for you guys.

Like I said back in Post #29.....


You can always use a AN-4 to 10mm banjo fitting as well, and use the existing banjo bolt, and new crush washers. This will prevent the fitting from causing any problems with your wastegate.

Here is the part number for this specific fitting and the place to get it:

Part Number: 3265-21

Pegasus - 4AN to 3/8 (10mm) Banjo Brake Adapter

I bought those same fittings and noticed that they touch the diaphram as well. That's why I went with the banjo fittings as well.

 

[BoostFrenzy]

Yeah, most of you guys did to the banjo route. I went straight 10mm x 1.00 to -4AN and it was too long. So until I can get around to laything it down to a good depth, I went back to the stock tial banjo bolt for the wastegate line.

It's not that I'm saying "don't do this!" it's just "do it right, or have to spend $50 for a new diaphram". Actually, me and my friend had an accident lastnight when his rubber boost source fell off and his turbo went crazy. Luckily nothing bad happened. Good way to blow a motor that way. He'll probably swap to SS too now.

Yeah, I hear ya. I had planned to turn down the length of the straight fittings, too. Then I found the banjo/AN fittings at work and decided to try those instead. The banjos are also a bit more "friendly" in tight spaces.

 

[slowgsr]

looks good.. all my vac lines are just push/pull style fittings good for more head than they will ever see and very strong secure fittings. Same stuff they use for airlines on trucks.

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.

i like your set up it is very clean

 

[andy4g63]

^^^ Thanks, man...
Boost Frenzy, are these fittings are the ones you are talking about...

http://www.extremepsi.com/store/customer/product.php?productid=22353&cat=1144&page=1

If these were too long, why didin't you put a THICK washer under the NUT of the fitting???
LMK, thanks, Andy.

 

[BoostFrenzy]

No I didn't get that one. At the time when I bought extremepsi didn't offer those. I ended up getting them from anplumbing because they are right down the freeway from my house. But, I will purchase 1 of those the next time I buy from extremepsi to see if the thread depth is any better. I have 2 of the fittings from anplumbing so one I'll shorten and the other I'll use as a reference to that fitting you linked.

Didn't have any washers that fit good haha

 

[andy4g63]

Well, GL and LMK, how the Extreme PSI fitting works out... I intend to buy these from them for my WG and BOV. Thanks for your time.

Just wanted to revive this old thread and say how amazing your guys setups look! I am in the process (right now actually) of piecing together a kit to do for myself.

Mine is slightly different though as I have the AEM Truboost solenoid + gauge. So looks like I have to also have a -4an T fitting between my external wastegate line, boost source and solenoid. Just wondering if you guys think you can get too long of lines to do this? I'm not 100% on the length of lines I will need as I will need 4 seperate lines but obviously too short will be worse than too long.

Also does anyone know the thread size for the vacuum port on the factory 2G intake manifold that you run to your BOV? Thanks for the help in advance folks!

Uh never mind the last question. After looking at it closer, they fitting is not a screw on type to the intake.
