The Hot Mess: quattro converted + 07k swapped Coupe GT

Postby vt10vt » Fri Jan 11, 2019 12:16 pm

Alright. The two other 07K build threads that popped up pushed me to finally start this thread.

Project name is because it's such an appealing combination of swaps/parts... but in reality it's a total mess :rofl:

Bit of back story, skip this paragraph to get straight to the goods. I bought a house in October of 2017, and honestly a large part of that decision was based around being able to undertake this build. At the time my plan was to start with a 4000cs and a pretty rough CGT that's been in the local junkyard for at least 12 years and combine the two into a shorty (Sport replica). Jim dug a 4000 shell out of the woods for me, which was missing most everything except for the chassis parts I needed. Then life happened, I spent a ton of time/effort on my B5 S4 and did a lot of auto-x/track events this summer, so not a lot of focus on this project. Then this spring a MUCH cleaner and more complete Coupe GT popped up an hour from my house for $600, so Dana and I adventured down with some tools, got it running and drove it home without issue. Because it's so nice and complete, the plan changed from SWB to LWB. The primary uses will auto-x, hillclimbs, and some track days, and I felt like a LWB is probably a better handling option for those kinds of events.

On to the pictures!

The Coupe and the 1/3 of the 4000cs from Jim that's left: My garage is under the house and ~11 x 23 with really low cielings and a big support beam in the middle. Not ideal, but AMAZING compared to every other space I've ever had to work in. Plus, with it being underground and only having one exterior wall it self regulates temperatures really well.

The mockup motor and trans in place:

Image

Driver side motor mount catches 3 M8 and 1 M12 (engine/trans bolt) to attach to the engine. To make this work, I slightly back cut one of the mounting bolts plastic and the metal insert that goes through. Luckily, the metal piece is what actually provides clamping force, so this is pretty easy to get precise.

Then engine mount was also moved outboard a couple inches to clear the filter housing. It's not the most elegant solution, but it all fits together really well!

Image

Passenger side engine mount was much easier:

Image

And the net result is that the hood *ALMOST* closes with the stock valve cover. With just a little trimming at the front of the hood I think I could make it work.

Image

Trans mounts were made from scratch using the original NF motor to help locate the trans:

Passenger side:

Image

Driver side:

Image

I thought the auto trans tunnel was going to be close-ish, at least in the front. Nope.

Image

4000 trans tunnel ready for surgery soon:

Image

The worst of the cancer I've found thus far:

Replacement section from donor 4k:

Starting to prep the 4K "shell" for donor surgery:

So that's about where I'm at with it! I have a REALLY exciting project that's going to help me a lot with this build, but it's going to take priority (mostly $$ priority) for a little bit, so I'm settling in for a long winter of chassis work which should be high effort but low investment.

My current plan is to remove both strut towers from the 4k, build a rudimentary chassis table/jig, and move those over to the CGT via some bracing and jigs. Then I'll have everything where it needs to live and I'll be able to build the subframe mounts from scratch. It seems to be the easiest/best way to go about it since I don't care about gas tank/floor pan differences (it'll be fuel cell etc etc). I'll keep this thread updated as that begins to take shape over the next few weeks!

Thanks for reading along, it feels good to be posting about my own shitty-old-audi again :D

Nice to see this come up! Should be an interesting combination of parts. Oh, and now I understand what you were saying about my new garage. What you have now is still way better than the shed you were doing all the work in down in MD! I'll be watching.

Figured I would.put it here too. I actually get updates from here...

Thanks everyone! Know that all your projects have been inspiring me along the way.

I'm thinking early block first, keep it stock, blow it up, take crank and move it to built later block. *plans subject to change*

Yeah, finally some context for my description! I have a lot of great memories of/in that shed... but I don't miss it haha I'll post pics of the rest of the shop eventually, but it's a mess right now...

Great built! I do love fancy billet parts that I can’t afford but garage fabbed is way more fun and nice to wait on yourself

There's even going to be some garage fabbed fancy billet parts in the future ;)

I'm not totally set on an exact plan of attack. I kind of need to get some other stuff done and see what seems most plausible, but fall back is basically using the stock rear part of the pan with the timing components cut down and mated to a new flange. *plans subject to change*

I don't know how you guys do it! Makes me want to start my own projects and learn how to fab and weld. A lot of kewl projects going on right now. Will stay tuned to see how this turns out. Need to get some motor Audi swag up on the walls!
