I just finished installing an A2 turbo on my 1.9 IDI and I am wondering if there is a way to increase the boost?
Perhaps something that connects between vacuum line and the waste-gate controller.
-
Plug it.
If you do a bit of searching on here you will find someone on the forum sells a controller you can put between the waste gate and the diaphram.
-
I see some posts where they blocked off a single metal line. Mine has two vacuum hoses. I didn't quite understand it all, my understanding is that they plug off both lines so that the waste-gate never opens and then they get full boost for whatever the turbo is putting out. I guess that would be 14-15lbs of boost. Is that correct?
-
If u plug the gate the fuel will regulate the boost.turn up the fuel youll see 30psi on a t3.
-
Just curious, but will I see an increase in MPG? Because right now I feel like I'm driving a gas burner.

I have a T3 on my 1.9 IDI with a blocked waste gate and fuel turned up.....I will see 40psi on a long pull in 4th gear. I try and not go over 30.
-

the T3 is only efficient to about 20 psi or so... so anything above and beyond that will most likely give you less MPG. it also takes fuel to spool the turbo, so that will also affect MPG.
best to just drive gingerly if you want better economy...
-
Unless I am mistaken I don't have a T3, I have an A2. It has two vacuum hoses. One is large and the other is smaller. Is there a max PSI for best efficiency?
-
I also forgot to add that my FI pump does not have the annaroid (sp?) on top. This engine came NA and all I did was add the turbo. I did not upgrade the pump but I did have the flow rate increased and changed the nozzles to pop at 155 bar. Is it absolutely necessary to have the other type of FI pump?
I also don't have an inter-cooler (yet) because it hasn't been above freezing in over a month. But I would like to add one at some point. And if I increase the boost I know that will affect the exhaust temps.
Suggestions?
Thanks for your input. You guys have it way over me on some of this stuff.
-
Who makes that turbo?
If you don't have the aneroid, you'll either be running lean under boost (limiting boost as well) or running super-rich out of boost. I'd opt for lean, given a choice.
-
The turbo came off of a VW Quantum.
-
maybe a Garret T2?from an eco?

40!!! sweet jesus!
I just plugged my waste gate with JB weld. ^.^

If you don't have the LDA (a "turbo" injection pump) you wont be adding fuel at higher rpm and by turning up the fueling you will be burning heaps more fuel on average. You're running rich for sure without an LDA.
-
not so much with the t2 its similar to the ko3 in size i think.Instant boost.the unburnt fuel shouldnt be to bad,if its a subtle amount.
-
Ahh. I'm not very familiar with smaller turbos. I guess with a little one and turned up fuel it's like .. boost all the time? (almost boost at idle? :P )
I can't stop thinking about what that other fellow said... 40psi in 4th gear??? oh my ***?! My gauge doesn't even go to 40psi
-
I hope this works. Here is a photo:

Here is an image of the turbo:

Heh. We hit 3 bar in our 1Z with our first chipset. lol. 3bar=43PSI. Stock everything but nozzles, turbo, and ECU. LOL.
Now it'll get around 2 bar on a full throttle loaded romp. No issues so far. Still stock exhaust... Whether is sorta keeping us away from getting the rest of the system installed. In Mintern, CO. lol. Little bit of a drive in snow.
BTW, this is a ECU direct reading off of a VAG-COM. Thanks to Kerma for the 3 bar MAP. And everything else. lol
-
Do you have any pictures of the serial # plaque. That looks like a regular old garrett T3 to me.
-
It's a T3.
If it was a T2, it would have water cooling connectors on the center, in addition to the oil feed connections seen in the picture.
-
the downpipe side looks almost rounded instead of square.The wastegate fitting on mk2/ t3 are threaded instead of nipples.

Here are some additional images:

Fixed it for ya Ed ^^^^^

from what i see in the pic, this is a Garrett airresearch T3 turbo.
same i have on me golf!
-
ooh yeah,
these babies can easily hit 35-40 psi with closed wastegate.
i know... (blown Metal Headgasket)
lifts the head right from the block man!!!!

Hey Guys, Thanks for the help identifying my turbo.
So if I put a boost controller on this T3 what is your input for type and PSI?
The link posted earlier has several varieties (single & two stage, manual and electronic).
http://www.boostcontroller.com/index.php?category=35
Keep in mind that I understand that any setting over stock will be a significant increase in power but I don't want to blow any gaskets or cook food on the exhaust manifold and I really just want to increase the fuel economy (until I can afford to upgrade the FIP to include the aneroid).
Comments please... :wink:
-
I would go with a manual Turbo XS and set it at about 20psi for daily driving. Do you have ARP head studs ?
-

Yeah, probably due extreme emp :roll: Closing wastegate is never a good thing to do.

That would be rich only during acceleration as steady state the fuel level is not affected by the LDA - that is to say, the amount of fuel injected regulated the amount of power and engine rpm.

i have no idea. This engine was installed in the truck when I bought it. It's suppose to be brand new and the same engine they sell in Canada and Europe. How would I know or even check?
I can post an image of the engine but I don't know if that will answer your question.

That is a 1.9 AAZ NA/ Non turbo engine you got there..
-
Take another look... that is an oil return on the back of the engine. The engine was designed for a turbo. These are photos from before the install of the turbo. I have been driving it with the turbo for the past 3 weeks. The person who installed it didn't want the expense of adding all of the extra hardware.
-
Here is the images after the installation:

I took another look and you didn't post pics of the engine code OR the pics of the turbo installed. :(
So ya your earlier pics are of a NA engine, wither it was designed for a turbo or not doesn't matter. T
You also didn't bother to mention the previous owner didn't want to add the turbo bits now did ya? :? :lol:
Sure is a clean sob that's for sure.
I'll bet it's WAY more fun to drive with the turbo.. :twisted:
-
Wow, an NA 1.9. I never knew they even made one. It even has the NA pump. It was an industrial engine only, and never made it into any vehicles to my knowledge.
-
that was in the transporters wasnt it?Hey those arent pvc drain couplers are they?I wouldnt use those if i was you. :?
-
Yes, correct on all counts!
It is definitely more fun to drive, but it's sucking too much fuel. That's why I'm here to glean some knowledge and experience from all of you fine blokes!
As it drives now, it's fine until I get on the freeway. I have it leaned out so that it tops out at around 80-85mph on the flat. I have been playing with the fuel and even an eighth of a turn puts it into a whole different kind of driving experience. It does not seem to use that much more fuel with the added turn and power increase. My thinking was if I got more boost all the way around that it would use less fuel. But, like someone pointed out already, when there is boost it needs more fuel and kind of looses power on long hills/upgrades. That of course is on the lean setting. The stock setting of the turbo diaphragm never gets more than 6psi. If I give it the extra bit of turn for the fuel it goes like a wild fire!
So, 20psi... that is the upper limit of my guage... I am just wondering how I would need to adjust the fuel (i.e. more or less)?
Thanks again for any input!

In Canada, the Transporter used a NA 5-cylinder.
