Here is a photo of my own ABZ (same V8 that Paul is using).

The red lines show where the jackshaft pretty much needs to run along side of the engine. As you can see, there is some stuff in the way. One thing not shown is the starter, right where the red lines meet the rear of the block (where the ring gear would be). STarter was removed from this engine, but it is also in the way.

There is also that PESKY right side CV joint. It takes up a lot of room.

Paul,
that's a nice alternator mount. I built mine completely from scratch, but its hard to do this with 3/16" thick sheet metal, as the thing warps as I welded it together. I like yours better. In my case, I also had to make the lower bracket mount the AC compressor as well. Luckily, the N* has a belt tensioner so no adjustment needed in the my case.

Paul,
would you post a comparison shot of the ABZ and the 1MZ comparing length of the engines? Perhaps a shot from above if they are side by side?

Today saw a little more progress, i got my new spigot fitted to the flywheel, had to travel to the Audi dealership for that little part, it was very expensive as well!



Also got my battery cable fitted, i'm front mounting the battery to even out the weight a little.



Biggest job today was sorting out my new fuel filler assembly and pipework, nothing clipped up properly but everything fits, so just the cosmetics to do on this and its finished.







Just need to paint the bay now and the engine is back in.

Why is the oil sump/pan so wide? Looks like an automatic trans pan.

You're asking me???
I'm not an Audi engine designer, so I can only guess.

Audi never intended for the ABZ to be mounted transverse. They also wanted to maximize oil capacity. The ABZ holds about 2 gallons!!! of oil.

I also noticed that for Audi, it was easier to go wider rather than longer with this engine. The engine is wider than it is long. 33" x 20.6 "
So the oil pan is just another part that is wider rather than long.

Oil pump is also in the way of the jackshaft.


Really the best way to use this engine is the way Paul is doing it in his Mk1, and MIke_H did in his Mk2--longitudinal with the Audi 01x gearbox. It bolts right up.

The best V8 to use transversely is the Northstar (at least in areas you can get N* such as USA).

They went wide instead of deep then for the oil sump. Makes sense. Most of he Audis sit pretty low. Good enough. i find that most new larger engines hold more oil than years ago. A standard smallblock Chevy/Ford/Dodge held like 5-5.5 quarts I think. I think new Ford Truck V8 hold like 7 or 8 quarts.

I have done a lot of work to the rear crossmember and added trusses to the sides of the pickup points for the subframe, this triangulation will give a lot more strength in a key area....





Also i took advice from an engineer on another forum and beefed up my alternator pivot bracket and added a manual tensioner at the same time....





I'm now a lick of paint away from refitting the engine and transmission.

My suspension subframe, transmission subframe and air filter housing have all been shot blasted and painted.

on the bracket for the alt. do you think that one lil bolt will be good to stand up against the torque pull and vibrations? i would expect something like this would have two mounting points. or weld it on the thick plate supporting the alt. i can just forecast problems with that one lil bolt.. you might as well weld it to the plate now vs trying to figure it out once that bad boy is back in your engine bay.

you must have missed the other bolt that holds the Alt--the one that acts as a hinge. Paul's alt mount is very similar to the 3S-GTE alt mount.

didn?t miss it. i know that there is a bolt up top.. and after looking at the stock one i guess its the same way.. i am a celica guy and switch the only over on my mr2 to celica style, which is supported much stronger. with that said.. i guess it will be find.. i just figured why not OD but i guess he does not have to.

The single bolt mounting for the tensioner is all i have i'm afraid, there is nothing else i can bolt to, i do think it will be fine like that though.

The only other thing i could do is drill and tap a hole in the lower casing, and beef the bracket up, but i really don't know how thick this casting is and what is on the other side of it....

Mega update today, i think i got more done today than any other day i've worked on the car, the weather was nice, i got left in peace and just cracked on with it.... so much for resting on the Sabbath!

Anyway i got the engine bay repainted, Supra Quicksilver of course, the colour the car is going to be when it's finished, and immediately hung the freshly overhauled V8....



As you can see i fitted the flywheel and new clutch assembly as well.

Not long after that the gearbox went on as well as the gearbox subframe and the new suspension subframe...





I made a mounting point for my oil filter relocation kit which also has my oil temp and oil pressure senders on it...
