So, since my last thread god burried, I figured I'd make a fresh thread since the goals have changes a little bit: In case you don't remember, I picked up a 1987 Coupe GT:   That I had intended to basically convert to a Coupe Quattro, I purchased a 10 valve Turbo motor to make that happen out of an Audi 200 Quattro:  Complete with rear end and transmission/front end. Then, I picked up this bastard:  A 1986 Audi 4000 Quattro, and since everything is kind of already put together, it made more sense to go with this car and keep the Coupe GT as a...well..Coupe GT. However, as I had already removed the engine and transmission from the Audi Coupe GT, I figure the 10 valve turbo motor can stay in the Coupe GT and the 2.3l 10:1 special motor can go into the 4000, later I'll get 20v pistons and head and turn it into a 20v Turbo motor (just need pistons, conn rods, and head) In the meantime, I pulled the 2.2l motor which was starting to sound bad and swapped in the 2.3l motor:     That worked great for a while, the 2.3l is MUCH more peppy than the 2.2l stock motor, however, recently its decided to act up, so I'm pulling apart the motor to trace down a metallic sound that happens at mid-RPMs. After changing the clutch hoping that was the source of the problem, I'm down to tearing the motor down to trace the issue. Saddly, its sucking away my roll-cage funds for its future amateur rally career... http://www.youtube.com/watch?v=hmCUBihS3_o    ...and here we are today:  I also have a VW TDI that decided to eat a valve after an engine upgrade.    Welcome to 'Knee Deep in the Volkswagen Automotive Group'

BlackMK4 posted:Gotcha. My car had a timing 'event' before I bought it and was told it has a new head. I'm budgeting to replace the head eventually since I'm sure it's not completely kosher. $300 is about $500 lower than I'd heard of, not bad. http://dutchautoparts.com/ Took about a week to get from the Netherlands to here, the head looks genuine and has all the VW stamps, pretty clean too. Came with cam, valve, lifters, everything except the timing gear and manifolds. One of the things you can look at on your head to tell if its genuine: Look for the ribbing on the front of the head inbetween #2 and #3 cylinders, if its lacking the ribbing, you might have a Chinese knockoff.

Before After  Cleaned up the piston deck on the Audi, this weekend I'm pulling the oil pan before I dig back into pulling the transmission. I also have to pull the oil pan on the TDI to get some markings off the #1 and #2 connecting rods so I can order new pistons and rods. They are a matched set, so you have to replace both. #1 and #2 are matched in weight and length, and #3 and #4 are matched as well, in reciprocating pairs to balance their unsprung weight CommieGIR fucked around with this message at 22:02 on Oct 18, 2013 |

Mystery noise from the Audi solved: This was trapped in between the flywheel and the bottom half of the. You can tell its been bouncing around a lot, its well shaved down. On the plus side, this is motivating me to get the old exhaust studs drilled out. As for the TDI, I'm stuck I have to buy a 5mm allen head ball socket to get the bolts out of the oil pan from behind the flywheel.

Welp, new pistons with new rings going in! Seated and torqued, headgasket in place  New head, all built up and waiting on some gasketing to dry  Head seated and torqued down, everything set to TDC and timing to slip the timing belt on  And there she is, just gotta finish hooking up hoses, slip in the injectors, re-installed the remaining parts and we'll see how she sounds in the morning.

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 |

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.

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.
