Hey everyone, not sure where to post this but here it goes.
Last weekend me and a friend picked up a 79 Audi Fox for him to restore. The guy selling it to him had planned on doing a 1.6TD swap from a quantum, with the quantum 5spd diesel transaxle. The engine has been sitting for a while, and seems to be all complete.
Question I have is, once I turn it over a few times by hand to make sure it is free, what should I do before attempting to start it?
I was planning on filling the IP, hooking up the feed and return lines, hooking up the battery, energizing the Fuel shutoff solenoid, the glowplugs momentarily, and starting it up. Anything else I should do as to avoid unneccesary wear and tear on the engine? I realize there could be some surface rust in places I can't see, but nothing to be worried about I assume.
Any input would be welcome.

Fully inspect the timing belt. Check the oil. You can remove the vacuum pump and spin the oil pump to pre-lube the engine without actually needing to turn the engine over.

Good idea, that is one of my favorite early style block tricks! Here is what I use accomplish that...

this and an electric drill!

Looks good, I usually just use a 12 or 13mm socket

Thanks for posting this GTiTDi.
For now the Fox is fine without the TD and 5 speed, but I can't wait to start working on the swap. Here are some pictures of the TD and 5 speed, and of the fox it will be going in.

FYI, you'll have to modify the trans tunnel a bit to get the 5 speed to fit in. Nothing major, but just something to consider.

Thanks for that reminder! I recall the seller telling us it would need a bit of "massaging" with a sledge hammer to make it fit! That is a pretty standard part of VW/Audi swaps lol! I had to bash in the frame rail to get the 1Z into my mk2 GTI

This will be a sweet build! That fox looks clean! All that bracketry on the backside of the motor looks like a clustered mess to me though! Is that a generator instead of an alternator? That is the first time I have seen one of these motors with that layout!

longitudinal engines use QUITE DIFFERENT looking alternators, from what is used on any transverse setup.. it looks just like the alternator used on my audi TD5 engine..

That old Audi looks so cool, a definite head turner.
It irks me that they're FWD though.

with VW/Audi, you primarily get FWD, or AWD.. not too many RWD cars built after the a/c beetles..

This is a generator(http://mgaguru.com/mgtech/electric/pics/gen_ad.jpg) not commonly used after prehistoric times (the sixties)
This is an alternator(http://i00.i.aliimg.com/photo/v0/415964648/Bosch_Alternator_0120469722_CA610IR_Used_On_VW.jpg)
Alternators are much larger in diameter and usually have an aluminum case.

That is exactly my point! It looks like a generator to me! If you look right above the A/C compressor, that looks more like a generator than an alternator!! No fins or anything! I thought dinosaurs only had those too. That is why I was shocked to even ponder that there might be one on a newer car. I might be young and naive but I have never seen an alternator with no fins. What is the final verdict?
Just because of the aesthetics of this motor, my personal taste would drive me to delete the A/C and power steering just to clean up those belts and find a more convenient spot for an alternator. I am turned off by all the mess that is posted by the exhaust. Seeing the motor turned "the right way" makes me wish that it was really RWD. Those setups are misleading! I am still very interested to see where this build goes!

It does have fins. It's a plastic fan, rather than steel, so the fins are smaller and enclosed at the front. If you look carefully you can see it.

One caveat for the QTD engine assy... look into the entry of the Quantum downpipe & notice that it's constricted internally (a ring or some such is welded in there), causing turbulence & cutting down at least a third of the flow capacity. That can be eliminated for quicker turbo spool-up & a more free-flowing exhaust. Ideal is supposed to be a 2.25-to-3"(or 3.5)" megaphone effect from the turbo back in the first 12 inches, and continuing at 3-3.5" for about 3ft or so, then gradually cut down to 2.5-3" for the rest of the way back to a low backpressure muffler (if you choose to run a muffler).
VW must have put that contriction in there to hold down total boost, max RPMs, or something re. warranty. It can't be optimum for performance or MPG. My 2 cents worth.

VW Smokr- how about restricting power for longevity? This is one reason why unmodified engines generally last longer....
I think we are gonna hog out the inside of the manifold a bit, some rough porting. Anyone have an extrudehone facility? ;D
funk- it still doesn't look like a generator. And believe me, we are not keeping anything but the water pump and alternator. After all, they are a necessity.

Every car I own from here on out is going to have A/C.
It's one of those things you don't think you need until you would just about kill for it.

Absolutely... however, my personal preference for 'restricting power' is related to the link between my right foot & my (usually) good judgement. Then, especially with a turbocharged diesel, there is no penalty for just carrying the 'potential' power... just in case a situation really requires it. Furthermore, at current fuel prices, the desire for the best fuel mileage is an important motivator, not to mention the absurd cost of traffic fines, vehicle insurance rates, tires, and replacement parts.

i REFUSE to have air conditioning in my cars. my Jetta HAD a/c, but i ripped it out. i dont like the belt setup on a gasser w/ ac, so i wanst gonna mess with it on a diesel..
