Turbo conversion kit for 1.6d NA

[?Waldo?]

I've used barbed/clamped oil cooler lines without issue.

[ndorian]

Do you know if most oil coolers are bi directional? The thing is I had 4 clamps on each line. 8 fail points really. I had tightened everything up in warmer weather but today after the failure I noticed that I could do several more turns on each clamp. If I can go to threaded lines, AN, I would feel better.

[ndorian]

I have a Seatrab oil cooler and cannot find info on if one port is "in" or if it doesn't matter.

[ndorian]

The way i reduced the lines was the problem. I added 4 additional hose barb reducers instead of replacing the original fittings.

[ndorian]

May I ask what ID hose you prefer for oil coolers?

[ndorian]

I decided on 1/2" ID hose for the oil cooler. I started the van today and drove around the block. Anti climactic. I can hear the turbo whistling louder when I give it fuel but I dont think I'm going any faster than I was before. I can't get the boost gauge to register any pressure though. I have it hooked into the waste gate. Nipple on intake elbow is capped. I would think that if I can hear the turbo I should see something on the gauge. Next step will be increasing max fuel.

[ndorian]

Will try going faster and maybe teeing off the intake elbow for the gauge first.

[ndorian]

So with no fuel increase I am seeing 5 psi max on the gauge. I am now going to start increasing fuel.

[ndorian]

So with a 1/4 turn clockwise on max fuel screw I have a whole new situation. Van feels "normal" in a great way. That little bit of added fuel was really nice.

[?Waldo?]

What boost pressure are you seeing now?

[ndorian]

On last run the gauge didnt seem to respond. It is dark now and Ive lost interior dash lighting (again) so I am calling it quits for today. Psyched for tommorow though...

[ndorian]

Gauges are still lit, its a foil thing.

Typically there's a fitting tapped directly into the snail shell of the turbo. This would provide boost pressure (when your boosting). Typically, there's a "T" in the hose coming off this fitting. From the "T", one hose goes to the waste gate actuator-can, and the other goes to the LDA (if you have an LDA). Tapping into this hose with another T would give you a boost signal. Also, tapping into the intake anywhere post turbo would do as well.

Are you using an analog (direct pressure reading) gauge, or is it electronic/digital? An electronic gauge needs a transducer to provide a relative signal to an electric gauge. I had a digital with a bad transducer. I've switched to analog because I had the transducer fail - which drove me nuts for a while.

The gauge is mechanical in that it has a hose attached. I have the NA IP so no LDA. Thanks for reply.

[ndorian]

I ended up plugging the waste gate and running hose from the intake elbow. Didn't have any extra hose to do a tee. One thing I need to do before driving it again is to secure the exhaust. It is temporary but with to connection to the van beside a thin metal hanger it is vibrating like mad and I don't want to damage the turbo itself. I am thinking about making a clamp by using a 1 1/2 in. clamp on the carrier bar bolted to a 2 1/2 in. clamp back to back and that would hold the pipe. I have a generic diesel cat. that I plan to install but still deciding on if I want to go straight or copy the original design and mount it cross ways, just using a cat in place of where muffler was.

It is best to only make/use brackets off the engine to hold the exhaust. Going to the body will rattle your brains out and eventually crack the exhaust.

Thanks for the tip. I had read about that issue and for now I am taking it down to basically the down pipe while I get my design sorted, One problem I will have is that one of the thread castings is broken on my oil pan so using the passenger side mount is not an option without a workaround for that bolt.

[Gizmoman]

Bummer about the bad thread if you mean the two on the aluminum pan tip, That is where my bracket is and holds a glass-pack muffler perfectly. I'd seriously consider tig-welding it up and tapping a new hole. I'll bet if you drained the oil someone could do it in place.

BTW, in one of your pics, I see a blue hose coming from the manifold elbow. Is that going to your boost gauge?

[ndorian]

Yes that is the hose going to gauge. You are thinking what I'm thinking on welding the oil pan.

[ndorian]

Having it welded I should say. I wish I could..
