Awesome work by the way!

Yes me as well I first got the car knowing nothing about it but i was mechanically inclined tho so it made life allot more easier but all the Audizine folk helped me allot :] The best site in the world for Audi fans/enthusiasts! great car and great build Britishturbo, and hats off for doing it out side . haha

Thanks man!
It was below freezing all last weekend when I was laying under the car working on the exhaust... brrrrrr lol

**TheKid84** · 01-04-2013 12:18 PM

Im from South Africa so it never really gets too cold.

Well that just motivated my a$$ to get going on my project. Have an office-full of suspension and chassis components waiting to be installed but like a pu$$y I've been waiting for warmer weather...

I just put on some insulated coveralls and Iw as good to go :-)

**britishturbo** · 01-04-2013 12:42 PM

So I'm picking up 725CC Injectors and a MAP sensor tonight on my way home ;-)

**Monty23** · 01-04-2013 12:50 PM

I'm sure you are aware of this, but the 750CC (@ 3bar) EV14 style injectors seem to be the standard upgrade around here. What injectors are you going with?

You are something else man.

Everything he does is against the grain, might as well be against the grain with his injectors too! lol

Sucks you couldnt use the 1600cc ones you had, resistor packs can really hurt reliability and driveability

Very impressed, good job on the rebuild.

**britishturbo** · 01-04-2013 04:30 PM

Injectors and map sensor acquired :-)

**britishturbo** · 01-04-2013 08:31 PM

725cc ID injectors. Going in tomorrow morning :-)

**MileMan402** · 01-04-2013 08:37 PM

Where did you manage to acquire those?

**britishturbo** · 01-04-2013 08:51 PM

From the State College S4 parts store :-P haha

**britishturbo** · 01-05-2013 01:38 PM

Anyone ever have a bad ECU be the cause of bad MAP sensor?
i.e. the sensor is fine but the ecu input for the map is bad?

I think that's my map sensor problem...

wiring is the only thing i can think of.

Wiring is fine.
5V at sensor plug between pin 1 and 3. And Continuity from Pin 4 to pin 101 of the ECU...

**phila_dot** · 01-05-2013 02:58 PM

I missed it, why do you think you have a bad MAP?

**britishturbo** · 01-05-2013 03:40 PM

CEL for map sensor.
Requested boost is identical to absolute boost.
Tried 3 diff sensors. :/

**britishturbo** · 01-06-2013 12:30 PM

So it seems like my MAP sensor issues are probably just because of its location... haha silly me.

**britishturbo** · 01-06-2013 12:30 PM

So I might be grabbing some yummy parts up in Canada while im there :-)

**britishturbo** · 01-06-2013 04:49 PM

For those curious here's my current turbo http://www.agpturbo.com/borg-warner-...-turbocharger/

My next turbo (For the 3.0 build) will probably be this: http://www.agpturbo.com/agp-zeta-3-2-ball-bearing/

**britishturbo** · 01-06-2013 04:50 PM

Oh and I forgot to add that I installed the 725CC injectors yesterday.
At the 4bar (58psi) that I am running them they are equivalent to 840CC.

Car is retuned for them for the most part, need to put on hold though until I get back from Montreal.

I have the AGP Zeta 3.0 Ball Bearing turbo on my ACR srt. Nice turbos!! Seems to spin for days after shut down. Love that you are going to be using one of these in a B5.

Did you have the MAP sensor post throttle body? Also, you really do want the wastegate reference to be pre-throttle body.

Yes. I had the MAP sensor post throttle body... I didn't think the ecu would freak out from seeing vacuum... I guess I was wrong haha :-)
As far as boost reference for waste gate I have always run off the intake manifold on every build I do.
It shouldn't make any difference because even with the map pure throttle body.
If I have any issues with it I'll plumb it per throttle body but it's unlikely to be needed.
Darn those Bosch engineers for checking for vacuum lol.

It does make a difference, and some people have had issues before on these cars setting up the WG vaccuum line post throttle body. Just trying to help you out.

Thanks for the heads up.
I'll probably move it anyway given how sensitive it was to the map sensor placement lol.
Given that the map has to be before the TB is does make sense that it would want the vacuum for WG in the same place too.

Cheers :-)

**britishturbo** · 01-07-2013 07:53 PM

Since I was up in Canada for business I stopped by the good people at INA... and wouldn't you know I'm leaving with a bunch of parts for my 3.0 build... oh boy!

**britishturbo** · 01-07-2013 08:52 PM

Goodies :-D

**Monty23** · 01-08-2013 03:17 AM

What pistons are you planning to run?

**britishturbo** · 01-08-2013 05:22 AM

Mahle

**Monty23** · 01-08-2013 05:25 AM

mmmmm good choice... What's your goals for the built motor setup? 1/4 times?

**britishturbo** · 01-08-2013 05:37 AM

Well I can do 450 - 500 whp with what I have now... so there would be no point doing the new build if it wasn't over 700whp ;-)
And she had better run 10's then lol.

But we shall see.
The boys at INA and I may be doing some things never seen before on the 2.7
And I could do an rs4 but we decided there's no point ;-)
