Audi V8 in a 924.
 
Hi All,
I am currently working on swapping a Audi 4.2 V8 into my 82
Currently working on getting everything squared in place then building engine mounts and Oil pan.

Wow, please bring this thread over to 924board.org... you'll get lots of love over there.

Wow! Awesome stuff. I "think" you'll need a bigger or an additional radiator though. The RS4 I had a few years ago got up to operating temperature within like a minute after I started it and always seem to have a great amount of heat up in that area under the hood.

Golten951 01-28-2017 10:56 AM

Thanks Jadewombat its been a fun project so far! I was thinking of the heat, so I went with of a triple core 26x19 radiator. also using a 19" dual speed fan. ^_^

jadewombat 02-03-2017 07:18 AM

If the fans are running all the time and you find you need more cooling, maybe some downward scoops in the hood. It would also improve downforce on the front end.

The Dodge Hellcats use this also. They made street cars that are made to run flat-out for a full 20 minutes.

This green 911 is/was on here from a few years ago and the owner fabricated the downward scoop. I've seen similar on 944s also.

Any updates?
What year V8 is it? ABH/ABZ?
Curious what clutch fly wheel combination you were planning to use

Hi Crave, nothing new yet, I have not been able to go up and work on her. I will be going this weekend, so ill have updates then.
I will be using the duel mass flywheel and pressure plate from the 2.7T Audi, then a Mazda/Ford 2.3L turbo clutch disk. Year engine is 2001 ABH If not mistaken. I will double check that number when I go home. Engine was pulled from a A8L with everything on it, paid $900 shipped.

Jfrahm 03-20-2017 05:42 AM

Nice. That should be an AUX engine, I did not know they might fit the chassis. I have 2 D2 Audis, great cars. You can get a whole car with a dead trans for $1000 or so and sell a bunch of parts to recoup costs. The engines are pretty robust although can get carboned up, maybe due to cheap gas.

The stock ECU is mated to the cluster and pared with the ignition keys so you may have to deal with the immobilizer if you are running the stock ECU.

Was looking over my paper work, yes, AUX is the correct code, After I get everything put into place I will be rebuilding the top end and new rod bearings.

ECU is already been reworked, so the VAG/IMO systems and the ties to the Auto trans have been removed.
Thank you for the information, If i blow this engine up I will give you a call ^_^

Will the bell housing bolt straight up to the 924 Torque Tube? They look compatible...but what kind of bellhousing is on the back of the V-8? Is that the one off of the 924 engine?

Rasta Monsta 03-21-2017 05:38 PM

931 bellhousing bolts to some audi v8s, but requires clocking the torque tube.

Hi, The Bellhousing is from a 924 turbo, with a Audi V-6 Spacer welded to it so i have more bolt holes to fit to.

You are 100% correct, the stock torque tube is coming out and a 944 one in going in. I have a plan to turn it slightly to allow the V8 to sit flat.

Does this all fit under the hood or you will have to modify it?

Hey Friends, Sorry i have not been able to do anything new with my V8 swap. In December I will have some good time off to do some work my swap ^_^ ^_^

I have taken that into account, added in some extra angle steel on the inside of the runners. After the engine is mounted i will be adding in some steel tubing for added strength.

Golten951 09-22-2017 10:11 PM

Update, Using a stage four 6 puk clutch disk from a Mazda RX8 with the Audi 2.7L Turbo Dual mass flywheel and Pressure plate. The Mazda Disc has the same size splines and shaft size as the 944, and only cost $40 to $60 for the Disc,versus $125 to $300. Will be using a Spec Push style throw out bearing. Lindsey Racing has the whole set up I will be purchasing. Measured everything out and it will fit nicely in the 931 Bellhousing I am using. Will post of pictures of it all set up this December.

Golten951 12-29-2017 08:39 PM

Updates!!
 
Hi All, Firewall is Completed and Battery tray fixed and sealed. Next will be seam sealing and POR15 for all exposed panels. Steering bearing has been moved back 2 inches and the sleeve around the steering column has been pressed back *too clear the Cylinder head to prevent from it vibrating on the metal*. engine is in and now time for Mounts, Oil Pan. cross-member and placing the Brake master and clutch Master. I wll Post up more pictures as i Progress.http://forums.pelicanparts.com/uploa...1514608302.jpg

Thank you. I am keeping the injection, sadly this model 4.2 is not the direct injection series. Out of an 2001 A8L.

jadewombat 04-23-2018 06:50 PM

Well, no kick at 5500rpms but at least you won't have to clean the carbon off the valves every 30K-40K miles. It'll still run like a bat out of hell though.

A little friendly advice if I may?? Those welds probably will hold, but if you want to try again it doesn't take but a couple of minutes to grind them back about 50% and just go over them. You're using a MIG machine?

The vertical welds you want to start at the uppermost point and weld downwards in a frown pattern (upside down "U"s) making good wall contact. This will hold the puddle where you want it instead of it dripping down on you.

Joining the welds along those sides you just do small circles, nice a slow with some overlap. I work as a full-time fabricator and make mistakes just like everyone else does. Nothing a grinder can't fix and a different approach until I'm happy with it. Can't wait to see this thing run!

that is some nice high quality welding, Wombat! Kudos

jadewombat 04-28-2018 07:46 AM

Thanks CAS. I suck at TIG at this point in my life. :( I'll get there though. ;)

Golten, are you going to use the original mufflers? My RS4 had the sport button with valves that would open the muffler and change the exhaust note. My daughter was 1 at the time and that rumble would put her right to sleep. :)

The Dodge hellcats have a similar setup, but it's purely mechanical. Not quite sure how it works but at a certain backpressure (or something) it opens the muffler.

Thanks for the input Wombat, I do appreciate it. i will be going back over everything and cleaning it up. And checking all the weld.
Im not sure of what muffler im going to use yet. Maybe just straight pipe it :-)

Not too bad a fit it looks like!

ADQ 08-19-2018 02:28 PM

Hi Golten951, I follow your work with interest since you started writing because it's a long time that this swap turns me overhead , I own two 931 second series and on one of them the work would be really good , the V8 Audi of the various A8 (ABZ and similar) is a great engine, light and powerful enough and has an exceptional sound.
Can I ask you how did you plan to solve the brake servo unit problem? Where do you put it?
The oil pan is manufactured from scratch?
What are the biggest problems you've encountered?
Thanks for the answers , I stay connected ;-)

Golten951 09-12-2018 02:18 PM

Hi ADQ, thank you for your interest! They are brilliant engines indeed! My brake master with be manual, no booster and will be offset from the pedal about 32mm with a enforced bracket. Oil pan will be fully from scratch out of 16 gauge steel. Biggest problem is going to be wiring and steering rack location. Going to be using a Mustang 2 steering rack. The pump pick up will be push towards the rear of the crossmember and drop do like the 924/944 pan. Hope this helps you out. Any one question please PM me or Email me at:golten1986@gmail.com
