View Full Version : Turbo Guys I need some help

We finally got that drag kit sold off. The guy that made the purchase has a few install questions. Here are the questions.

Ok i'm just about done with the questions about the turbo installation.
I have just about everything figured out, except a few last questions.
Here goes, on the Tial wastegate there is two small screw holes, one on
the top and one on the side ( what are these for) i know one goes to the
intake, but what is the other used for. Can i use for my boost gauge and
if i can does it matter which one. Also i read on the box where the
spring is set at .45 bar what psi is that and how do i adjust. Next, on
the oil lines which one is suppose to be on top ( i assume the oil feed
line, which is the small metal goodyear line right) just wanting to make
sure. Also i was checking my kit last night and i have a metal flange
that goes on the bottom of the turbo for the oil return line. The one
that is used to screw that brass fitting into for my return hose, but
the feed line looks like there is suppose to be a metal flange for it to
but i didnt receive one. It also has threads to where the feed line
could screw directly into the turbo housing. I need to know do i just
install the metal line or am i missing a flange. Also the 90 degree
metal pipe the comes with the oil fittings is that what is welded into
the oil pan and if so how far in do u weld it and does it matter which
way it is welded ( sideways, straight up, etc.). Next, i got the missing
link with my kit, do i still have to use the check valves with my kit?
Finally, on my Greddy Blow off valve, it has two connectors what do they
hook to im guessing the top one to the intake , but then there is
another one the is angled what does it go to. Please answer these
questions for me and i will get out of your hair plus give you guys a
thumbs up to everyone that i talk to.

Ok, here's what I can answer...
The two holes on the waste gate... one goes to the turbo so it will "see" boost/vacuum. Not sure on the other one, but I think it goes to the charge pipe on the intake side. The smaller line is the feed line, it goes on top, the larger line, is the oil return, it goes to the oil pan. Not sure on the fittings thing, that is a kit specific question. Mount the 90 degree fitting in the pan so that it gives the most direct route to the return line. doesn't matter orientation, but I would put it facing up. You shouldn't need check valves if you have a missing link, thats what it is. As for the blow off valve. You only need to use the top one. I have no clue what the smaller one is for, I don't it hooked up on mine, and it works fine. Hope this helps.

as far as I know, the hole on the top of the tial is for an electronic boost controller.

The 2 nipples on the gate are used for boost control. If you are using a manual controller, use the bottom nipple ONLY, and do not block off the top nipple.





If you are using an electronic boost controller, you have the option of using either both of the nipples, or just the bottom nipple. It's all in how you run the hoses, and how accurate you want control to be. With both nipples used (bottom is fed from the intake manifold [ pressure source ], top is fed from the stepper motor of your controller, which is in turn also fed from the intake manifold [ pressure source ] ), you will have more accurate control, but nearly all of the electronic controllers will cause slower spool than a good ball & spring manual controller. This is due to their 'fluttering' of the wastegate as you close on your target pressure in order to make the transition 'smooth'.

My hallman spools faster than my profec B.

$0.02 worth.

Awesome, thank you guys very much. I'll post any other questions the guy may have :)

John, is that true only with an external? I tried to explain this once on the list but it was shot down. Everyone said a Profec B will spool as fast as an MBC. I don't know a whole lot about the stepping motors in those voodoo boxes so I didn't argue.

.45 bar = 6.615 PSI

1 bar = 14.7 psi

No - it's true of EBCs in general. I have butt-o-meter proof, but nothing more. And the design of EBCs dictate this type of behavior.

The IQ of the CoDSM list has degraded sharply over the past yr or 2. :(

hrmm..my calc says its 1bar = 14.50377psi

thats reasonably close..but whats the real number?

.45bar to it..would be 6.52669psi

weird. :p

That's what I thought. I have been hearing that for a long time and it made perfect sense. I made something similar to the Hallman for my car for $8, I'll be laughing all the way to the finish line with it.

EBC who?
