Well, not what I was thinking but that is the direction I was guessing. Something being wrong in there, stuck spring, shim, something messed in the gov...The lda stuck would give little to no boost power. Hopefully this works out for you now.

Tastes like diesel with a hint of oil aftertaste.

Now get an intercooler on there and a turbine that you can at least fit your thumb into and you'll experience some real power.    :P 8)

I have a full T3 setup as one of my next steps.. ;) Intercooler and my .216's are next for sure. Then probably an 02A.. Lmao

SO. All the B/S that was totally unresponsive to proper tuning? The governor shaft getting hung up internally.... fml.



I could feel that I had popped the cage out of the lever with my frigging around so I needed to remove the lid anyway and have a look. The cage was out of the lever, and then I saw the gouge marks.. apparently it wasn't seated properly in its slot. Live and learn. Next time I get that symptom?! I've got it covered! lol.

So anyway, I have the throttle shaft at its most CW position and the idle screw backed physically all the way out. I then have the max fuel screw in roughly 2-3 full turns from factory LR settings (had paint and collar on it). Chris, you need to get that fuel screw in! HOLY CRAP!

I am non intercooled and running stock boost/waste gate. Got lots of smoke.. so I got lots of room for wayyy moorree booost :)

Does size really matter?

I'm sure you guys know I HATE lag and prefer smaller turbos to big ones, but, IMO the K03 is just too small for a 1.9.  Even at stock boost pressures you can feel the top end hurt from it.  On the other hand, my VNT15 is physically as small, but with the vanes open it flows better than turbos that are physically much larger.  With the vanes closed it boosts faster than a k03.  Before too long I will be fitting an 1852v to an ALH.  Mmmmm....

So my girlfriend keeps telling me.. ;)

Now you guys gotta remember I am still on an 020 trans here, and at stock boost.. I can hear my waste gate open with a little more than 1/3 pedal. So an inter cooler, my bigger nozzles (Veg .216) and up the boost to 18-20psi and it should be about all the 020 can handle. Then before too much else, I guess I gotta get the 02A I have sorted out as well...

3rd gear, dry pavement, traction issues.

What is all involved in installing a diff kit in to an 02A? I figure I might as well start thinking big picture here and go for broke...

Peloquin Diff Kit? comes with everything needed to install it it would seem, including the $100 ARP bolt kit.

From what I gather the wavetrack are supposed to have more traction than the peloquin models. Just going from what broke vw has told me on his tests. He also said they were supposed to change the hardening process as the last one he installed cut the splines off of the arp bolts when they were pressed in. He was worried they wouldn't have enough bite to tighten them or keep them in there, so he contacted them and they said they were softening them a bit. That was the bolts would have the splines left and it would be a tighter fit.

As far as the install, if it is like the 020, then I believe you have to pull everything to get to the ring and pinion. If it is different then I do not know what would be done.
