While we're on the subject of alternative injectors, what do we think about these?

http://www.ebay.com/itm/03-04-Mustang-Cobra-Ford-Racing-39-pound-Fuel-Injectors-/230870732554?pt=Motors_Car_Truck_Parts_Accessories&hash=item35c0f7cf0a&vxp=mtr

They can be had used for around 100 bucks for 8, add flow testing and cleaning and you're still looking very good on the price. The datasheets are readily available as well.

Awesome build!  Glad I stumbled onto this, well done.


Yup, the injectors are the same as those that Five0 sell, as well as USRT, myself and possibly a few others.  Great injectors for our 5 valve Audi's, and their dual cone pattern, cone angle, and offset angle better match the stock RS4 specs than any other EV14.  And like he mentioned, they have EV1 electrical connectors, so no need for adapters.  They are the best EV14 injectors that someone can buy for our cars IMO, for someone looking for an injector around that flow rate (if someone is looking for higher flow rate, there are better options around 1000cc.)

In addition to discovering and correcting the reason my car had run like crap on an EPL Stage 3 tune (EGT Faults were coded out, but not EGT function), I deleted the ridiculous brake safety throttle cut.

Went out again this evening, and drove the A6 for about 45 minutes.   Run after run of left foot braking while keeping the engine under continuous load.  Then did about 15 minutes of 2nd, 3rd, and 4th gear pulls at 1 bar.  I think the rings should be seated by now.

This weekend, I've got to throw in the aluminum TBB, V-Band Bi-pipes, and the 95mm MAF tube.   Then the real tuning begins.

As a side project, I had to do some work on my front bumper and re-spray it (2 years of bumper hack job running the JHM FMIC.  Too many supports were cut out, so I had to stiffen it up a bit). 

Since a gallon of Charcoal Metallic was only a few bucks more than a quart of Tornado Red, I made a rash decision and went with the Charcoal.  So I guess I have a bit of another project.   Paint the rest of the car.  Fun, Fun.    If it saves me one speeding ticket, it was worth it.

Cheers.

The problem with the ASJ/AZR is that all that stuff about nice spray pattern goes to waste, because you will be spraying that dual cone of yours exactly into the manifold/port wall.
For RS4 application it is much better to either just get the 980cc Bosch Motorsport with 30 degree cone... or there is actually ONE injector Bosch produces that matches the specs quite well and does not cost 2000 EUR a piece
These with dual narrow cone will need lots of wall film adjustment to get good throttle response.

As to OP - your project is looking great.
Regarding MBC - you need to learn to use the LDRAPP and CWMDAPP constants. And you can make runs at fixed DC.
If you want your boost control to work decently you will have to anyway.

More Info on this DREAM build Please !!! Prettiest Eye Candy I've ever seen. Would you have done anything differently ?? I will be Building my A6 soon !!! By the way the Bore, your Built heads and quick spooling Turbos are why this Engine Revs so quickly !!!

As a whole, I wouldn't do much differently.  Here are a few things I was proud of, and some things to think about:
Machine shop, Import Engine Supply did a great job on the block/heads/crank/ and verifying pin fitment/rod fitment.  They Spec'd everything down to the 10,000th, and taught me a ton..... just make sure you tell your machinist - better yet, write in paint pen on the crank - to not fill in the crank pin hole when balancing the RA.

Be sure to transfer the oil pump cog from the 2.7 crank.  They are different sizes.  10 minutes in the freezer and install is a piece of cake.
Install the front and rear flanges with oil pump chain and tensioner right after you get the rotating assembly in.  THEN do the other things like oil pump/upper oil pan.

Speaking of oil pump/upper oil pan, if you go with main studs, be sure to test fit, grind, and re fit until these will fit with clearance on pump/pan with the main studs torqued.   Do this prior to ever pulling the crank out of the plastic.

Plan for many, many hours when file fitting your rings.

I would use some assembly lube without Moly' next time.  The oil filter on change after first start up weighed a ton. 

I would consider skipping on the non-stretch headbolts next time - just because it sucks cracking open your valve covers again after its starts and warms up but before you drive it... It is good to have the insurance though.  Also, if you go with 034/Eurospec Headbolts, they use the regular 12pt not the polydrive.  I was kicking myself and cursing them for a week while I waited for the 12pt to arrive.
 
Lots of questions still to be answered though:

• How will these intercoolers perform on this setup? 
  Will the RS6Rs flow enough for a 3L to take advantage of the build heads?
  Will the clutch hold?  (I was on the fence between the ceramic and the feramic.  I went with drivability and crossed fingers)
  Damn did I torque the rod bolts?  Kidding.
  And what kind of torque/power will this make
  What will my ET/TRAP be at Firebird International Raceway (FIR) this summer @ 2700 feet above sealevel?

I'd have liked to have used 4032 alloy pistons, but I didn't see an option for them on a stroker build. Maybe Supertech?  If this motor fails, I will go with these: http://www.intengineering.com/mahle-2-7t-30v-piston-set-81-5mm-bore-86-4mm-stroke-9-1-cr
My spare block is already bored/honed for them.   Another thought would be to build a high compression E85 motor, but then we are back to the higher thermal expansion alloy.

ANYONE HAVE A CONNECTION ON 4032 Alloy Custom Pistons for stroker or high comp set-ups?

Everything about this build is for a daily driver with a mean torque curve.   Warming up the car for 15 minutes gets to be a chore every morning.

Need any parts for your build?  What's left of the the gray car is for sale!!

Wow I am Amazed at your skill level and dedication !! Again awesome build and I used to Race my cars at Firebird as well, I also am a Chaplain with RFC and used to support that track as well as SCCA events. I am an IE DEALER so whatever you want let me know and I'll help out the best I can...
