pictures of the downpipe please!!!!!

If that 02 bung is for a wideband, you should reposition it. Install instructions say that the sensor needs to be mounted relatively vertically between 10 and 2 to keep moisture out etc.

That is actually the 1.5" v-band ferrule which will connect the crossover pipe between the wastegate and the downpipe. The bung position for the o2 is about 3" from the upper v-band @ the turbo, its only marked with a sharpee so it cant be seen from these pics.

I started the harness tonight, lots of tech-flex - going for that clean OEM look :-D

That's what I get for not paying attention to details....3 inches is pretty close though, might have overheating problems.

Looking good either way! 8)

looks good guys!!! keep it up!

:stupid:

I know quite a few people were burning them out when that close. Mine is at the bottom of the downpipe, and worked great.

it might not be 3" but it is at the outer portion of that first bend, so maybe 5" ?

derracuda · Post by **derracuda** » Fri Jul 18, 2008 8:49 am

too close sean... it needs to be at the bottom of the DP minimum. the WB sensors are kinda finicky, but it's up to you. if you move it now, you'll be ahead of the curve and not have to pull the DP back out to re-weld a new bung later

OR! weld two bungs now, then run your WB sensor up top, and when you burn it out, you can then switch to the lower location, that way you can see what we're all talking about

If John has already welded it I'll just plug it, I have like 3 plugs... Information on this stuff is all over the place, whats a guy to do.

Post by **Hank** » Fri Jul 18, 2008 10:19 am

Yeah, just save that one for narrow band should you ever want to use it.. LOL..

I think my dad knows that the 02 has to be down pretty low... I guess he has never done it before, but meh, not a big deal

quattro v1.0 · Post by **quattro v1.0** » Fri Jul 18, 2008 12:33 pm

Well hopefully he was sick of welding when he left yesterday with the pieces, we kinda picked the spot together thinking it was as good of spot as any. Honestly though, I had considered running both WB and NB.

When is my favorite aluminum-guy coming back to Vegas for a few days? I hear that wolf may be interested in your services as well for a lil UrQ project he has going..

Post by **Hank** » Fri Jul 18, 2008 12:59 pm

yeah, I am sure we can do something. I am trying to get up next weekend, but I need to find a ride..

Post by **Hank** » Fri Jul 18, 2008 2:20 pm

Um, My dad didnt weld it. He is up here in SLC, and will be back monday morning. What do you want welded in Aluminum, and what does Wolf want

My conscience, and other reasons convinced me to pull the head over the weekend. I added ARP studs and 20v gasket. I guess since I will have to do it, I might as well do it now. I got a warm fuzzie when I measured the valves, they are indeed 40mm as I was told by the PO. I was really happy with how the cylinders and head looked, again, it was worth the peace of mind to do it now.

Everything is back together and I have been running harness here and there. The ECU is mounted on the back side of the glove box, I'll be able to access the com cable thru the glove box.

I finished my version of the cooling mod, I changed my mind along the way and decided to do one large outlet rather than 3 small ones. I used the boss at the #5 cylinder and drilled it out, 9/16" then tapped it with 3/8NPT.

I sourced a 90 degree 3/8 NPT to 8AN and ran -8 braided up to the main coolant outlet up front and used a 14mm to AN8 adapter and then connected it with standard -8 90 degree.

Its a little hard to see the details, but maybe I'll get some better pics in the daytime. It is a gratuitous shot of the coil setup though

I had time for one more small project tonight so I layed in the heat shielding where the header / downpipe nears the chassis. Timing cover is off, I media blasted it tonight and will wrinkle paint it before it goes back on.

The plumbing is all complete, I will add some fire sleeve to the hot-zones and it should all be ready to button up.

Today would have been my first day in the Virgin Islands, US Govt paying, nice per diem etc... Oh yea, woulda been there for 11 days. I guess Im committed to this daggum project and making it to the UrQ25 event. Or else just outright committed. I turned down two trips to get this car done. So its gonna get done ;o] I found out I will be traveling to WA State late August / Sept to make up for my other trips, any car stuff going on up there?

Looks good Sean!!! I was feeling bad that I left town with Emily for a 1000 mile motorcycle ride and didn't get the downpipe welded up. I can tell you up front and for sure that UT35 between Kamas and Duchesne up by Park City is one of the nicest stretches of motorcycle highway in the country. The only drawback that I could see was that at 8000 ft my bike got slower. LOL I have to work tomorrow, but should be able to get to the downpipe Wed. It looks like you kept busy.

Im sure you saw the red flags that got thrown in on our O2 placement, we can rethink that - it's currently the least of my worries right now though. I would like to get that DP in and complete so I can tighten things down and really start sorting out the left-overs.

I dremel'd the header flanges and they fit alot better. I plugged the exhaust temp bung so the header is about as ready as it's gonna get.

Maybe a turbo would help your altitude problem? lol

quattro87 · Post by **quattro87** » Mon Jul 28, 2008 7:52 pm

Sean, the down pipe is pretty much ready to install except I need to weld a copper o-ring for the wastegate flange. I will try to find a suitable size wire at work tonight, but if you wantto slide on by the house and pick it up it's in the garage. Hank should be at the house sometime tonight or early morning.

quattro v1.0 · Post by **quattro v1.0** » Mon Jul 28, 2008 11:22 pm

Sounds good John, thanks again. I will try and make a bee line over there tomorrow (possibly during work hours) or in the evening. If you can leave it somewhere I can grab it I'd appreciate it - or else if hank will be there during the day still?

I have to admit I need a bit of a boost, Im starting to feel a bit defeated. My to-do list is getting longer not shorter, albeit its just little jobs, they still need to be done. Not that I don't think it will run in 8 days, but can it run 600 miles without any sorting out...

Tell me if this is stupid, but for the sake of getting the car going with less headaches - should I do the initial startup / run with the standard O2 sensor and then piggy-back the LC-1 in once it moves on its own?

derracuda · Post by **derracuda** » Mon Jul 28, 2008 11:27 pm

sept. 7th is a vw/audi show in woodburn,OR ... there's a sticky in the meetings forum. i plan to be there with my zermatt car and A6 if i can get one of my friends to drive it there for me

where in WA are you coming to? maybe we can meet up sometime?

Derek, I will be in both Bellingham and Seattle over the course of maybe a week / week and a half. there should be a weekend in there too so I will have to double check the dates again.

I don't see any advantage to using a NB o2 when most likely you wont have it tuned and dialed in enough to run closed loop and you will need the WB to tune with any way. We might as well just stick the WB in to begin with. If you want me to weld the other bung in we can have both, but if just one lets stick with WB.

Hank ought to be around today working on his Urq. I'm still at work and will have to sleep a bit, but I ought to be up and around by noon.
