1.6 Swap into A3 Golf?

[1oldcj]

So to clarify the title alittle.

I have a 92 Jetta with a stock 1.6 N/A, But the body is rough around the edges. Floors need two holes patched. Needs a hood, fender, trunk lid, rear quarters. But its the windshield that has killed it for me. Not completely rotten but around the drip tubes for the moon roof have started to go and around the bottom of the glass itself.

Next is a 99 Golf 4dr that has some paint bubbles but is much easier to repair.
Golf currently has an ABA (2.0L 8V) hooked to a DFQ (020) trans.

What I want to do is plant the 1.6 in place of the ABA. And keep the DFQ with the 1.6 and ditch the AWY.

I realize i may loose my tach but I don't want to loose the rest of the dash stuff (warning buzzers, GP lights, etc)

Will I be able to wire that stuff up fairly easily or am I barking up the wrong tree?

Anything else I may be forgetting?

Thanks for your help!

Most of your warning lights, and most definitely your CEL in the Mk3, are tripped by the engine management computer. You wouldn't retain them if you put a 1.6 diesel in there, because the diesel won't have or need the sensors that computer is looking for.

Not really sure, but it's entirely possible some of your gauges won't work, either, but I may be thinking of the even newer cars' clusters.

I think the a3 came with a 1.9 idi but I don't know what it had for ECM.

Kind of thinking out loud but doesn't the fuel sending unit stuff go through the ECM.

I can go aftermarket gauges but would prefer the stock look over some hacked together pos.

Wonder if a dash swap would be easier?

mk2 dash into an mk3?

I'm looking at trying to do the same with a 96 Mk3.  I'd like to keep the tach mostly.  I've been looking at wiring diagrams (i'm not the best at) but the pickup off the crank on the MK3 looks like it goes to the ecu and then to the tach.  Has anyone had any experience with MK3 cars?  I've seen pics of modifying front fo intercooler (either here or vwvortec).

Do you have to keep the ecu to run the tach?  To run fuel pump as a lift pump, to have the speedometer, etc?

I'd love to have those answer as much as you!

my old 92 jetta had the tach reading directly from the ECU. so i imagine yours is the same.
is your speedo cable driven or electronic? if its electronic, i imagine the ECU needs to work to control it too.
and as for the fuel pump, it only runs when it has an ignition signal from the engine. like, it needs a signal from the distributor of a gas engine. and a diesel has no distributor or spark ignition system. your best bet to keep everything working as it should: find an AAZ equipped MK3 and take all the specific parts off.

the speedo is electric too.

What I was thinking was buying a vaccum pump and putting the gasser distributor in the mech. vaccum pumps place.  I know I can get the hall sensor in the distributor to send a signal for the tach, the question is will it work with the ecu and tach in the car?

Cluster is pretty much all ECM controlled for sure, but you can put an AAZ cluster in.  You MIGHT need the AAZ body control module too since it handles the glow plugs, not sure what interaction it has with the cluster.  But if you find an AAZ donor car you're good to go.

Speedo is definitely electric, but the electric sensor fits the earlier tranny...

For the most part the AAZ harness will just plug in to the senders on a 1.6 without any trouble.  There will be some extra senders on the motor (for instance you only have a single temp sender on a Mk III), and you may have some extra wiring, but nothing that matters.  I've got a few loose danglies in my engine bay...

African engineering is not the best way. i think the gas computer pretty much needs a gas engine attached to it to function like it does now. get an aaz cluster and a w terminal alternator. that fixes that problem. and is way WAY more simple. i would look for the right parts out of an aaz car and go that route. cause then when you have wiring problems (all vw's do) it will be easier to diagnose, cause it wont be an all hacked together abortion.

Thanks for the help, know anyone that might have what I'm going to need, such as the aaz cluster and wiring.  Ebay? for the cluster?

look for someone selling a whole car as parts? i know rust is a plague in canada. find a really really rusty donor car.. search craigslist lots. and keep an eye on the diesel forums.
