Turbo conversion kit for 1.6d NA

[?Waldo?]

You can get a brand new Vanagon 1.6TD oil pan for ~$200 shipped. Just a data point.

Thanks. I cannot seem to get above 7 psi. boost. More fuel?

[ndorian]

Would it be okay to advance the max fuel screw by a full turn?

[ndorian]

Going for a half turn. Be back with results.

As I recall, you don't have an LDA which meters fuel based on boost. I'm far from an expert but I'd be very careful adding too much fuel.

Also, if you are not reading EGT temps, too much fuel can melt your pistons long before you see water temps rise - speaking from experience here.

That said, 1/2 turn shouldn't hurt - enough to hit 8-10 psi would be where I'd stop.

Hey thanks, I have an EGT gauge and I look at it a lot. I realize now that I am kind of on my own as far as liability.

[ndorian]

As for tonight I think I am done.

A good days work - glad to hear you watch EGTs - turn away!

Thanks.

So a half turn really didn't do much. It is the same old thing of speed shifting and flooring it constantly. I did get boost up to 8 whilst flooring it in 4th but that was fleeting. Oil temps got up to 180 deg. It has been a great learning experience but I'm starting to think that I should have put the money into a 1.9 TDI or TD conversion.

EGT's never got above 700-800 max.

I didn't read the whole thing, just took a peek at the Hans site for the kit linked in the 1st post
but I wonder what size that turbo really equates to?

I had a K24 from a quantum 1.6TD in my van (and the quantum originally)
it struggled in the van on big hills, would stay slow if you had to get out of it.
iirc the wastegate was limited to ~8psi oem

I then upgraded the turbo to a smaller K14 (eco-diesel or european 1.7TD) and it was much more responsive, almost quick and in general a pleasure to drive.. took that motor NY to FL and didn't lack on the highway (teamed with a air cooled transaxle)

so 8 psi is enough to keep pace with basic traffic.. it's no rocket ship but it's driveable.. with the smaller turbo I could let off the throttle on a hill when I encountered a truck and regain boost to pass said truck. w/the K24 I would still have to follow the truck up the truck lane..

all this was with a LDA boost sensitive injection pump.

so w/o boost enrichment you may be at your limits.

To danfromsyr,
Hey, I swapped out the whole Hans kit for a DIY kit that I put together myself. The turbo is a real KKK K03 sourced from good old TheSamba.com. To you both, thanks for the sage advice.

[ndorian]

Turbo was NOS.

[ndorian]

Transmission is 5 speed from an 1989 vehicle. Doka truck as I am told.

Plugging the line to the wastegate is a good test. The AAZ K03 turbo is spec’d at 9-12 psi wide open throttle in 2nd gear, best tested accelerating or climbing a hill.

Adjusting the fueling on a non-turbo pump is a trade off between excessive smoke and power. Too much fuel gives lots of black smoke and high EGTs climbing hills, not to mention worse fuel economy.

I will try plugging the distress tube, I mean waste gate. I don't have a tach so I can't do those ratios. One day.. Going to take a spin in a few though and try driving a bit harder. Confidence...

Also lucky for me, I live near the east coast and the land is really flat.
