Project DRTHWGN

[v8coupe]

I was told this is the new old skool Audi hang out. So being as I am an old skool audi nuter I'm here.

My current project is to restore/improve my 91 200 20vt Avant! I bought the car as a shell thinking i was going to drop a V8 in it, which I love. Well that changed the day I got my hands on a Eurovan short block! I've kinda had a hard-on for a Stroker wagon since I saw one in OH a few years ago. Just something about the Audi I5 sound in something that makes torque like a Big block Chevy makes me giggle.

So that car will be built in stages. I need it for winter, but there isn't enough time/money to do a properly built 2.6L tall deck 20vt before winter. Luckily I have a wrecked 200 20vt sedan in the stable to donate an engine for a while, before it finds it's home in my fathers CQ. So I'll drop that in with a new timing belt and some new seals to keep all the oil leaks to a minimum. It's a little on the tired side, but still makes good power so I'll just do a pull and swap, it's only got ~275k on it.

The biggest thing I'm doing right now is getting the chassis setup. I was getting ready to build a V8Q 6-speed with a ton of suspension upgrades, before the wiring harness in the frame rail went poof! So I have a pile of really nice upgrade parts in the garage. 2B camber plates, DIY coil over kit, 92 S4 rear subframe and Hap bar, V8 Euro 6-speed mounts, Axles for a t44 6-speed, and a brand spanky new 28mm front V8Q bar. I lucked out when I bought this wagon as the PO was a real Audi nut and didn't even cut the harness out of it to build his Ersatz S2. It also came with Koni adjustables all the way around with ~5k miles on them so that will work nicely with the DIY (ground control) coil overs.

The last area this thing really needs to have addressed is the brakes. It's a UFO car and thus the best option is to hop right into a Hp2 variant brakes system. Since I know where I'm going for power I know stock Hp2's are not going to be adequate for it's braking needs. I'll be going with my favorite BBK the T-reg 6-pots. I have them on my MK5 rabbit Daily and they are silly amounts of brake for the money and are almost a bolt on to the UFO housing. I'm still debating the rear setup, but I'm really leaning toward setting it up with the T-reg 4-pot rears and going with a Viper e-brake caliper. I'll be playing with ideas there as the stock rear calipers are done so I need something and a 330mm rear would be fun!

The Goal is to have the wagon sitting right and up and running for a show in Oct so I got some work to do. luckily it's mostly labor intensive stuff to swap out the suspension bits, get the coil overs setup and the car back down then throw in a 01E 6-speed and complete Urs4 shifter setup and a clutch masters 850 setup and get everything dialed in. Get the Chassis all dialed in and learn how it behaves under modest power. Mean while build a full high power 2.6L 20vt to slap my little Hx52 on.

I'll get some pictures shortly for all you.

Welcome! I'm pumped to see the chassis tweaks!

Welcome! I'm pumped to see the chassis tweaks!

Thanks. I've been building the parts pile to do this for a while. I just hope it will handle as good as I hope!

[Hank]

Need more pictures to go along with these awesome plans!!

[v8coupe]

I'm working on it. Hopefully have some tomorrow with test fitting of my OZ mito's. Hopefully get the clutch all boxed up as well to go out to Clutch masters. I feel with my power goals that the twin disc is the only route that makes sense.

[v8coupe]

Some pictures not the best quality, but it's all I got for the time being.

[v8coupe]

well test fit my OZ's on my mk5 rabbit to see if they cleared the 18z T-reg brake setup and with a spacer they would. That's good, so a 350mm rotor and a 6-pot caliper can fit inside these wheels. Just one more reason I love them. Currently working on picking up another set of calipers (probably the smaller 17z) to get them mocked up on the 200 UFO housings with S8 345mm by 30mm rotors.

pictures for proof they do fit.

[WOMBAT]

That is awesome. Brakes are stuffed in there haha

[Hank]

Insane amount of brake for the wheel! LOL

[v8coupe]

I can tell you the 18z brake package is insane levels of brakes for any wheel. They engage so quickly the ABS isn't quite sure what to do.

little update on this I've been working on it and am almost done building the engine for it. I couldn't get the 3B out in time due to space issues at my shop so I am building a Mutt. Using a 7A long block that I picked up cheap as the base of the engine. 3B exhaust manifold and WG with 2.2 bar spring, 7A cams, 3B/7A dizzy setup, AAN intake, K26 from a 20vt, 20vt oil filter housing, and a 7A clutch package with stage 2 clutch. Not a bad pile of parts for a temp engine I built from spares. I have a IA stage 3+ to run the whole thing on hopefully the 7A is up for that. I setup the oil return and oil cooler with -10 lines. The oil cooler is also from a V8Q so it's a little bigger then the factory.

Going to be doing an 01E conversion on this car using a setup I bought years ago when I was going to 6-speed convert my V8Q before the wiring burned up in it. So I have a set of new V8Q 6-speed mounts, a complete URS4 shift linkage, 01E slave/master line, a set of URS4 axles modified to fit the t44/D1 chassis and a set of new transmission mounts. Only thing I need is to swap a V8Q front subframe in the car (which I have several of). I also have a Euro 28mm V8 front bar I'll throw in there. Transmission will be a DQT code 01E I have had collecting dust in the corner since i started my coupe build 6 years ago.

7A is 10.3:1... you are going to run into issues with that kind of compression and 20-22psi of that IA 3+ chip. You should at the very least stack some gaskets in there to get it hopefully below 10:1. Stock 20vT's are 9.3:1

Also, do you ahve the distributor in yet? does it fit with the AAN manifold? Speaking of the manifold, what is your plan for the radiator?

Not trying to be a debbie downer, just wondering.

[EDIGREG]

10.3:1, perfect for E85

[v8coupe]

Dizzy fits fine, early AAN's in europe used a capped off dizzy for the CPS.

I'm aware of the higher compression, I don't think it will be that big of an issue with a larger then stock IC and the cold air up here in the north land. I plan on my stroker being 10:1.

Radiator issue I haven't resolved yet, waiting on a set of 200 motor mount arms so I can mount the engine in the chassis.

I've built several 1.8t's with similar boost on similar compression and not had issues with them (stock internals with thinner gaskets).

[Mcstiff]

*10.2:1 I thought?

Did your 1.8ts have cast pistons?

I can confirm that a stock, never opened, 7a can survive at~200kpa with E85. Sometime this fall my clutch started slipping so I've been running on spring only since. I'm on a street tune so I'd guess that a day of dyno tuning could allow for a safe tune with additional boost. Honestly, I'm deciding if I should kick off the upgrade avalanche by installing my AAN shortblock when I get around to doing the clutch (so DM rods, clean up bottom end, all new gaskets, ARPs) or just doing a clutch and sticking with the 7a a bit longer so I can get on the dyno and tune a bit.

Regardless, I've wondered what would happen if you put a 3b harness, ECU, and turbo parts on a 7a so I'm interested to see what happens here!

[v8coupe]

if it blows up it blows up. I wasn't going to spend the money a real 20vt costs when I have no plans to keep it stock and no plans to stay 2.2/2.3L.

I've seen many stock 3b's pushed far beyond were people thought they can go and the IA isn't known for being the most aggressive chip on the planet.

It will max out the stock K26 that is for sure.

[v8coupe]

finally getting back to this project. My Rabbit has been eating up funds as has my tow vehicle. So engine is ready to see what she can take but this k26 turbo stuff is a Joke. I just snagged a good deal on an AAN harness, VEMS, LS coil pack setup, and wide band off a buddies S4 he's parting. So now to see how long the 7At mutt likes to get hit with a "big" snail. I know it will eventually die as it's not forged pistons and 10.3:1 is a bit high, but I plan to build a 10:1 stroker so be a good way to see how cams and such can make high compression work.

Also going to go 6-speed on this thing since I have all the parts kickin on the shelf still so 7A flywheel and clutch also purchased.

As for the Rad questions I had picked up a ABY S2 intake to use the stock 200 rad, but I am going to save that for something else. I'm switching the Wagon over to a V8Q front clip with Euro Headlights. this will include the V8 Radiator assembly. this opens up the side of the engine for a HUGE IC with a top exit to go into the AAN intake. I'm talking a 3-4" core as big as the 200 rad angled to fit. engine is ready Vems is ready, trans is ready just need to do a little more measuring before I cut the 200 core support off to fit the V8 unit.

When the 7A dies I hopefully will have my rabbit done, so I can start build my idea of a monster Stroker. goal is street setting of 500hp with on the fly switchable map up to 800+hp on pump.

Sounds cool!
