Bobby Singh's Audi S2 avant project

[bobby singh]

Rear crank seal fitted using this borrowed tool

Oil pump machined - this is to allow the fluid filled pulley to have some clearance

All sump bolts cleaned

Getting there

Cheers
Bobby

Head parts are finally here:

Door card cloth

So the doorcard on the S2 have been degrading over time and the backing has been breaking away:

As you see above I managed to get hold of the origional material from Audi Tradition

Next task was to drill off the plastic welding for the door pockets

(wonder how long that gum has been there)

Ready for action:

Final result:

Used cable tie as welding rod and plastic welded the pockets back on:

Cheers

New exhaust cam - managed to get hold of a brand new ABY exhaust cam

New s2 boot badge

B5 fuel tank shield (apparently with minor modification it can be used on the b4). Mine was totally rusted through so removed it sometime ago.

Boot wiring repair kit

Found this on ebay - have no use for it but old new stock is always nice

Cheers

There's been a lot going on with the S2 in the background and its finally back from a full paint job.
Yes it was done last year however I wasn't happy with the colour match so best way to get around that is to have the whole lot done.
It come out very good and I'm impressed by the Bodyshop I used - they get my recommendation.

Nice to see the car is still solid under the body kit.

Here is a video:

Maxx ecu mounted in the OEM position

3 x 0-5v inputs
6 x egt's
Wideband

6 bar back pressure sensor wired in

Cylinder head -
I bought another 7a head and had it converted to ABY spec (the other head had a tight cam bearing which will get fixed and kept spare) with new guides, all high points machined down, valves lapped in and skimmed

I will install the new inlet ABY cam (purchased from AT) with a 7a exhaust cam

Cheers

Maxx datastream

So the Maxx ecu has a nice feature whereby it can datastream over bluetooth.
Bought an 8" tablet and made it removal by installing Neodymium magnets behind switch blanks

RS2 spec on Maxx ecu:

To get a base line of the current spec with the maxx I went back to the dyno:

Running 1.75bar (previously 1.85) and now making 370hp / 515nm (wouldn't want anymore than this on stock rods)

Replacement Cam belt cover (back) - Previous one was cracked and not suitable for turbo coolant return

New EVAP unit

Some AN fittings for the turbo oil & coolant

Cam cover hs been Cerakote (Thin ceramic coating) - Sprayed on with advantages being:
stable against UV
Chemical can not touch it (even acetone)

High grade turbo studs and bolts

Cheers

Im also planning on using PWM for the fuel pump - This R8 item is a nice simple 5 pin unit

Bought this bracket to mount the actuator in the bottom location

EFR83 test fit:

RS2 turbo and wagner manifold removed for a test fit

(very tight but should be doable)
