Audi 80 Quattro (Type 89) - AAN Engine Conversion

[bazburn]

1st ones...

[lcsmith]

Thats actually not strictly possible I don't think, well the car wouldn't be that low........It was more an Illustrative photoshop, they're Compomotive TH1880's, specially made for a company called TTD Motorsport they're a copy of the OZ rallying wheel and come in 18 x 8........I could probably get them on but as previously discussed, the car would handle like sh*t and it would be too high..........Shame though

[bazburn]

Thats cheating... throwing curve balls, but they do look the best IMHO

PS I'm not playing anymore ( ball under arm on way home... )

Right news.....

Removed the engine from the S4 last week and it's sitting on the floor waiting for mock up with all my ABY parts.....

The clutch I was going to use is fooked, so I'm going to get one as part of the sachs performance clutch group buy

Went to the garage tonight at 7.15pm and had to removed damn near the entire interior to get to the wiring loom!!

Anyway had the engine loom removed completely by 10pm, so it's been thrown out of the way!!

Tomorrow I'd hope to get the ABY loom installed, and I'll need to do a tidy up in the garage, it looks like a bombs gone off in there with bits lying everywhere!!!

I'll keep you updated with progress but should be making steady progress with this during the next few weeks....

Great news post some pics as you go so people can get an idea of what is involved

[lcsmith]

Cheers Tonks , I have some pics but will take more and plenty of them I'll upload them tomorrow, I promise!

The wiring looks amazingly simple so far (touch wood ), but I did download these guides from S2central.net;

http://www.s2central.net/S2_Schematics/ABY_Wiring.pdf

http://www.s2central.net/S2_Schematics/Schematic_Primer.pdf

Those are absolute gold dust, never seen anything like it, so simply set out and methodical, sheer brilliance!

Saying all that I have only "removed" the 6A engine loom, now I have to install the ABY one and find homes for everything......fingers crossed!

[lcsmith]

Right spent today laying the ABY wiring loom out on the floor and labelling every wire and multiplug using the aforementioned s2central wiring guide.

So I've got some photos, I must firstly apologise for the quality they're blurry and just basically *****! Here goes...........

Heres some pics of the winring loom fully labelled;








A few more pics of the engine coming out (including the most important 9 inch grinder!!);


















Some photos of the all the parts removed in order to gain access to remove the engine wiring loom and install the new loom;


















However there are a few plugs unidentified, theres a relay been spliced in connecting the engine loom to the dash loom, and there are a couple of plugs that were unplugged from the old 6A loom that don't appear on the new ABY loom........

Two black multiplugs coming directly from the firewall bung;












Little black plug with green and yellow wire coming directly from the firewall bung;






Relay 204 wired into engine loom connecting it permanantly to dash loom, I thought this may have been something to do with an aftermarket immobiliser....but don't know;








Four plugs on OLD 6A loom that don't appear on the new ABY loom, I think that two of them may have been not been plugged in when I removed the old loom though...?










Black Plug leading to additional harness leading to another black plug, coming directly from firewall bung;










Any help gladly appreciated!!

the last one should be the outside temp. sensor.

Looks like "coding plug" T6d

Cheers Mate!.....I'm just back from the garage, my friend told me what it was too

Ah yes T6d I see now, page 32 of the wiring guide, it says if in doubt leave it unplugged.

The other plug will be the Ambient Pressure Sensor F96 then.

[Tonks4x4]

This is for ambient air pressure


Brown wire is earth
The other brown/yellow is the feed from outside temp display to the back of the clocks.




The wiring to your relay does look like someone has spliced in an aftermarket immob. remove it and clean up the connections

Plug on the left is the plug to the reverse lights, remove the wiring from the old 6A loom and plug it back in and give it the correct feeds.

I cant quite make out the colour codings on the brown plug to tell you what it is...

[lcsmith]

Right got some more info on the unidentified plugs on OLD 6A loom

Round Brown Plug;

• 2 x Blue with Yellow stripe
• 1 x Brown with Red Stripe
• 1 x Green with Red Stripe

These smaller two.....

White Plug;

• 1 x Blue with White Stripe

Yellow Plug;

• 1 x Yellow with Green Stripe

I hope that helps......I have to say again - the photos are horrific!!!

Update,

I'm getting somes engine parts painted, and we're going to strip down the engine bay tomorrow and prep for paint.

I've also started collecting RS2 parts for later
.......got an RS2 engine manifold tonight and I'm looking at a set of injectors, they're 440ccm at 3 bar fuel pressure, 4 jet, high impedance 14 ohms, EV1 design

Pic;


The question is are they straight swap and suitable alongside RS2 Turbo, RS2 intercooler, 3" exhaust and a remap?

Update
I’ve been gathering parts now for the past few months, and decided to wait until I have all the parts before progressing with this any further (plus I’ve just got married and we’re doing a renovation / conversion of an old church so time is at a premium!!)

I’m planning on cleaning and painting all the components and building up the engine on an engine stand, might as well make it all look nice while you have the chance!

Well so far I’ve got;

Hoffer RS2 Hybrid Turbo
Hoffer RS2 Mapped ECU to 350bhp ish
RS2 Injectors
RS2 Exhaust Manifold
ABY Wiring Loom
ABY Inlet Manifold
ABY Rocker Cover
ABY Boost Pressure Pipe
ABY Water Rail
ABY Fuel Rail
ABY PCV System
ABY 2.75inch Stainless Downpipe
Audi 90 5 Cylinder Clocks
OEM look Boost Gauge
Black Audi Vent Gauge Holder
Audi 90 Plumbing & Brackets
Audi 90 Sachs Performance Clutch kit with reinforced pressure plate and organic clutch
Porsche 996 calipers - 996.351.425 & 426
Audi URS4 HP2 314mm discs

I need to get;

Audi RS2 Intercooler
Bambridge brackets for Mounting 996 calipers to Audi 80Q Struts

Intercooler questions;

1. Do I need an ABY / RS2 crossmember for mounting the RS2 intercooler? – or is it simple enough to just make one.
2. Can I use the Standard Audi 80 front bumper with the RS2 Intercooler? – From the pics I’ve looked at most people seem to be fitting S2 / RS2 bumpers or the facelift front ends, I would rather keep the original bumper for the wolf in sheeps clothing look…….
3. Would it be simpler to look for a slimline intercooler and make up a custom crossmember?

RS2 intercooler fits directly on an RS2 crossmember, it fits to an ABY if you make/modify a bracket.

RS2 intercooler will not fit behind a stock bumper without cutting the bottom out of it.

What are you doing rad wise? (as that will make a difference to your intercooler setup)
