S2 seen for sale

Spotted this on the bay .................http://cgi.ebay.co.uk/Audi-80-S2-Ava...item3a61f7dd67

Nothing to do with me

[simon20vq]

Me to looks pretty good spec, does anyone know anything about the spec? I thought this conversion produced 310BHP but that is without head work and I can see head work makes that much difference? Also running on standard injectors, is that sort of powere possible?
Thanks for any advice.

Looks good in titan grey, never seen one in that colour before.

reminds me of my tdi avant s2 rep. Nice nothelle wheels on it.

MTM stage 2 by the looks of it.
I doubt it has original injectors. Perhaps the owner forgot to mention it.

Stage 3 has 420 ps, sq maf, Porsche 440 injectors.

[T2Andy]

It will have the original injectors they don't change them

Well, then you need more fuel pressure.
Original injectors max out at about 1.25 bar @ 6000 rpm on stock head and 4 bar fpr IIRC.
That's with a small turbo. With a larger turbo / better intercooling they'll max out sooner.

So something is not right.

[T2Andy]

Your right that's why I had to upgrade more parts on the same convertion

[simon20vq]

How can you tell if its standard injectors from looking at them? If they are upgraded what should they be, how can you tell?
Thanks

[T2Andy]

Standard are black where as Rs2 ones are green ,also part no on the side .

[T2Andy]

You upgrade them to what power you need ,440bhp will require 440cc injectors or above ,you map the car to the injector . Bosch do a 440cc green injector ,we need high impedance on our cars.

[simon20vq]

Cool sort of what I thought, but if they are standard how can it be running that bhp? Could MTM reprogram ecu to squirt more fuel for longer on each compression cycle?

Only thing you need to change for injectors are latency compensation and krkte.
You don't need to change the maps in the car at all, if it was mapped previously...

Sorry.... in english? (Excuse the joke)

[T2Andy]

my mtm upgrade same as above was too lean as the injectors were maxing out so had to upgrade them ,my point is the mtm upgrade doesnt make the power quoted ,how can it on standard S2 injectors
