Audi is fired up and out of the garage, gotta play with the timing a bit, but she is moving under her own power and the clutch is working!.

Glad to see this thread back, Commie. I suppose being from CO you're enjoying this heat wave we're having in ATL right now?

Saddly, no snow. I had to disassemble the drivers side Macpherson strut last night, as it was popping, found out the cap hadn't seated on the spring properly.

Fixed the popping strut, made some home made collars to keep the strut retainer from butting the strut tower when its at full extension. Previous Owner had removed the collars and threw away a bunch of the suspension parts. I found a stray ground that was loose, coming off the intake that was freaking out the idle and fuel regulator. Now it sounds nice and smooth. Might have a faulty thermostat, the engine warms but doesn't go over barely above low temp. Also, looks like the center diff lock vacuum nipple has fractured, as I can lock the diff but it won't unlock it, and the vacuum line is loose and there is no nipple to be found. Stage II Planning I've made some contacts for the turbo manifold, downpipe, and turbo. I currently do not have access to my 10 valve turbo motor in Wyoming, so I have to buy another to install into the current motor. I'm pricing the roll cage parts out now, and have a TIG certified friend who will be helping me install, hopefully in spring. CommieGIR fucked around with this message at 23:45 on Jan 5, 2014 |

Update: 20v Turbo motor acquired. Pictures to follow On the downside: CIS fuel distributor poo poo the bed when I drove down for guard weekend, ended up having to trailer the car home.

How much pressure can you put on a stock block before you start blowing poo poo apart?

BrokenKnucklez posted:How much pressure can you put on a stock block before you start blowing poo poo apart? Its a KKK K24, I'm told 17 PSI is the max 'efficient' boost of it. Around 300HP is the max it can probably push with the stock turbo, and 450 HP is the max HP the engine can handle before you risk bending a connecting rod or breaking a headbolt. I plan to put in ARP headstuds down the road.

So quick calculations: 1986 Audi 4000 Quattro Curb weight: 2842 lbs @ 115 HP (81 HP per US Ton) 1989 Audi 200 Quattro Curb weight: 3351 lbs @ 217 HP (131 HP per US Ton) 1986 Audi 4000 Quattro w/ 3B 20v: 2842 lbs @ 217 HP (153 HP per US Ton) So yeah, there is going to be a significant performance improvement right off the bat.

Yeah.... 300 HP is going to really be a kick in the rear end. There is a huge line between a 250HP car and a 300HP car, for some reason, when you hit that mark, things become way better.

Teardown time!   First things first: This engine has NOT been run in a LONG time, you can tell, the camshafts look brand new and have only the lightest coating of oil, the engine has great compression, and the wiring on the knock sensors is all dry rotted out. Otherwise, so far so good, I'm considering pulling the head just to make sure everything is all good. Weirdest part: The head is a 20v, but the engine code identifies it as an MC, which was a 10v turbo block, not a 20v. Makes me a little bit curious if it has the 20v pistons or if someone just tried to mix and match a 10v block with a 20v head. However, the features of the block match up with a 20v 3B from 1991.

So, a little bad news: The block that this came with is actually an MC block, and the compression ratio is a little too low for the 20v to really function. The good news is the NG motor that is already in the 4k Quattro will work just fine with the 20v head once I swap out pistons. It lacks piston oil squirters, but extra cooling can make up for that. It should work out to around 8.3:1 CR, the MC will barely make 7.3:1 CR, but the NG with its 10:1 stock compression should eek out comparable CR to the stock 3B block.

You could run low compression and boost it +30 psi  Could you just have the head or block skimmed and run a thinner head gasket?

mafoose posted:You could run low compression and boost it +30 psi Possibly, but it makes more sense to just use the block that is in the car that has the correct CR anyways and has been vouched for by others who have built such hybrids. I'll probably save the MC block for parts, but at this point running the NG seems like the better (and easier from a buildup standpoint) plan

Started disassembling the engine bay to do the swap, meanwhile the oil pan for the 20v is at the machine shop to get some bolts drilled out. First days progress    Just from a brief comparison, its looking more and more likely that the battery is going to have to move to the trunk or the rear seat.

The 5000 had its battery under the rear seat, so it's not like it's unprecedented. Just make sure to get the special low-height battery so you don't end up like me shorting out a seat on the battery whenever you go over a bump.

I love the 4KQ so much. I bought one for $1300, drove it 2-3 years only changing the oil, and then sold it for $1300. Car had 240,000 miles when I got rid of it and still ran well. I don't think I ever drove a car better suited for winter weather.
