Not my B4 but my co-worker Mike and I swapped out the original stock nozzles for a set of PP520s I had in bodies from my race car. His car was low on power (even considering it is stock) and smoked more than it should. He backed out of the drive and was surprised to chirp the tires starting out in first without trying.

Set the IQ to 2.4, car runs smooth, no smoke, and the power bump is, shall we say, significant.

What ECU is he running? I have a spare set of later bodies I wanted to put PP520's in, as I like them in my Jetta, but wasn't sure if the earlier ECU would like the higher primary pop-pressures of the later bodies.

Just put in two lower balljoints, as the right side was developing some play.

Two, because one is silly.

He's running the BK, the early one. The higher pop pressure didn't seem to matter, timing is still right near the top of the graph.

I plan to mount some Sprint 520s in his bodies and make sure they're all good, and then we'll swap out the PP520s. He's planning on getting a tune, too. I have a GQ ecu with no chips in it we may try out, although I had a great experience with a chipped BK in my B4V.

IBW, any other mods to your friends' engine? How many miles on the clutch? I'm considering Sprints or PP520, but I have a stock clutch with 175k on it.

No other mods. Clutch is, AFAIK, original. I do think with a chip and Sprints it's likely to slip after 170K. But maybe not. The older cars' clutches are more robust.

Yup, chip and larger nozzles will slip. Passat clutch is good with one, pick your poison.

Work on the Interior swap for I-Red continued with the recovered headliner install. I'm not having any luck at all finding pre-molded carpet for the B4 or any other Passat for that matter via Yahoo search. Does anyone have any leads?

Tony, Passat clutches, some hold, some don't.

I moved to a gt2056v from a jeep, with race520's a bit of smoke and it did not slip. Would that have lasted? I doubt it. When I got the clutch changed The springs on the 230k mile clutch were about to let loose, but the clutch face still had plenty of life left. my stock Luk clutch did me well, but you won't know if you got a Luk in there or not.

So, on b4/a3 clutches, ymmv on if it slips with the mods or not. But if you got some miles, just be ready for a replacement, you can't ask for TOO much now =)

Yeah, I'll have to put it off until we get more money coming in. Can't quite afford nozzles, much less a clutch!

Put the tailgate latch back in and still have the tailgate open alarm LED on the dash. and still have the cluster clock being reset each time I turn on the engine.

Finally remembered the VagCom. I have one error - Air Bag low intermittent B+ voltage. So I guess it is time to measure the voltage from the battery and all the way to the cluster,

Clean the grounds near the battery, as well as the main engine ground. File or sandpaper will work fine. Coat with either dielectric grease or noalux before reassembly. Either one will prevent oxidation.

It's in the A3 Cabrio, but it has B4 content:
I stripped down a B4 GLX driver's seat for the bottom pan and the height and rake adjustability. I transferred the A3 bottom foam and leather and the forward fold seat back to the B4 pan
Now I have the same "barca-lounger", front up / back down, seat position that I so liked from the B4s.

I'm pondering the feasibility of transferring the B4 lumbar adjust back to the A3 seat. My concern is the cables for the A3 fold-forward release interfering with the lumbar adjustment gearing.
