My Audi 2007 Audi A4 2.0 TDIquattro - 2.7 biturbo swap, approved by DMV

[Julian Aksnes]

Hello!
My name is Julian and i live in the middle of Norway.
I bought a 2007 B7 2.0 tdi quattro for a couple of years ago.
The color is Lava Grey
This summer i filled in a application to change my engine and sent it off to the norwegian department of motor vehicles (Statens Vegvesen)
Surprisingly, they approved my application, based on my argument that the raw chassi of the A4 B7 is the same as the S4 B7. The V8 in the S4 has higher emissions than the 2.7 biturbo, and based on that I got it approved :)
I also need to change my brakes into 3.2 FSI brakes, and use the original exhaust, cats, ECU and all the original harness from the 2.7 donor-car.
Ive recently started collecting the parts I need for my project, but I aint expecting any assembling in the upcoming year tho. If things go well I will have the only legal B7 with 2.7biturbo in Norway

Some pics from when I bought it





In 2014 i got myself some 19" RS6-2`s



And before this season i bought 18" Alphards




Before the winter kicked in I installed the upgraded frontbrakes from a 3.2 FSI. 288x25mm vs 321x30mm


Before


After



Im planning to install the JHM RS6-R turbos on the engine, combined with upgraded internals and exhaust.
Then it will be some modding to make this work with the b7 wiring

Nice! It's always good to have another B7 A4 build going on.

Since the cluster needs to be swapped from a diesel to a petrol one, why not buy a Rs4 cluster?


Im having some difficulties reading the PIN from both housings.. the VAG Tacho appears to read the instrument ECU (RB8) but after reading it, it says "OK!" but the "Read PIN" button is still greyed out..
Have to look further into this.
Anyhow, it looks kinda sexy!

Nice to see another Norwegian :D
Have you checked the requirements to make it legal? Its awesome if its possible :P

Based on the first post, it sounds like it is already good to go.

yes thats right, would be nice to what the requirements actually is tho
EDIT: Im fuckin blind, all the key details is in the first post

[Julian Aksnes]

Thats right, I already got it approved :) Im going to pickup a C5 2.7 in Sweden this summer, and will strip the car down this fall. During the winter I`ll try to hook up my B7 with the 2.7

[Julian Aksnes]

A quick photo of how the car looks right now :)



This weekend me and my buddy drove 11hours to North-Sweden and got myself a 2003 Audi A6 2.7 biturbo manual (250hp) with the right enginecode, BES :)


Now its time to rip this car apart ;D

[al3k]

Awesome! this project will be very interesting. I was actually on a vacation to Luleå with my family last week, very nice weather and cheap beer

[Julian Aksnes]

I`ve now removed the BES engine from the C5 bay :)
Had to drop down the subframe to get it out, very very narrow down there!








I have also got my RS4 cluster installed :) Looks pretty awesome, even tho its a diesel (for now :D)


A couple of quick photos of the car from today :)

[Julian Aksnes]

I`ve started the teardown of the engine


The engine block looks pretty dirty.. looking forward to giving it some love and care!


Measured the cylinder wear to 2/100 (metric). Its pretty good for a engine with 250.000km on it


The work-bench :D

[georgio3gr]

Great project!!! Will you also need to change the fuel lines or tank?

[Julian Aksnes]

Great project!!! Will you also need to change the fuel lines or tank?

Thanks!
Yeah, I need to change the tank. I dont know if I can use the diesel-lines yet, but my guess is that it will work if the connections are the same

[Julian Aksnes]

..completed the teardown




Pistons,rods and crankshaft out in one piece


The engineblock ready for some strip-all and some TLC (wash and paint)

[Julian Aksnes]

The C5 donorcar is out


..time to put the b7 back in the workshop!




Everything is loosened.. bolts, hoses, harness, everything is ready for engine removal next time Ì`m home :) Then I will try to fit the v6 block onto the subfram to see how it sits

[vvenom800tt]

Godt og se en annen nordman her.

Veldig fin bil du har der.

[Homer]

I'll take that TDI drivetrain off your hands

[Lucian189]

Why not a 3.0 tdi ??
For a daily car would be great....

Because I`m not into tractor engines :)

Im using the diesel-drivetrain for this project :D

[phatjames167]

What wheels are these? They look great on the avant!

[themadscientist]

Very nice. You'll be very happy with the JHM turbos.

[SamsonKnight]

Glad to see another 2.7t swap! Keep it coming!

[Nollywood]

Nice! Another B7 2.7T swap to subscribe to.

[Julian Aksnes]

I can see I`ve forgot to update you guys here!
Here comes all updates since september
2.0 TDI engine out


The weight of the 2.0 TDI engine, 210 KG


Checked my 02X gearbox while I was at it just for fun, 76 kg :)


Spacerplate checked out nicely, biturbo spacerplate fits on the 02X


Then it was just one thing left to do, pair the engine block and gearbox to see how it fits!


And voilà, 2.7 biturbo paired with 02X quattro box :)

[Julian Aksnes]

Testing the fitment of the engine on its mountings


Fits perfectly on the trans and engine mounts :)




Left and right enginemount




Transmission mount fits up 100%


The snubmount was going to be a problem, which I was aware of. This forum claims that the 3.0 snubmount and frontplate will fit, but thats not correct. More information coming below...

[Julian Aksnes]

I also read that the OEM downpipes wouldnt fit on B6. Thats wierd, the B6 and B7 isnt any different?


Well, in my B7 it fits perfectly :)


Here`s the left downpipe


And the right one


The downpipes slides pass the trans mounting aswell ;)


Ofcourse I had to test my headers and intake pipes to see how it looked :D

[Julian Aksnes]

According to the audizine forums the 3.0 engine mount would fit, so I bought that..

2.7 biturbo mount to the left, 3.0 V6 to the right


So here is the 2.7 biturbo snub


And heres the 3.0.... mismatch aswell

[Julian Aksnes]

so then I had to do some measuring, and finally I got my hands on a 3.2 FSI front section

3.2 FSI from B7 that is, so the whole frontframe is bolt-on

3.2 frame at the top, 2.0 TDI in the bottom


So then we had to check how this badboy fitted on the engine mount


And yeah, it was a match! :) Now the engine is fitted 100% on OEM mounts

[Julian Aksnes]

So then I had to take the engine out for the real overhaulin.


Santa came with some snacks for my engine, so we can start on the engine right away:)
H-beam rods to handle the 600hp turbos im planning to use. JHM RS6-RS

[blitz2190]

very nice, but it has always been known on here that you needed the core support from a 3.0/3.2 from for the snub mount, cant wait to see another swap running.

[sagafaen]

is the 2tdi a BRD?

[Julian Aksnes]

is the 2tdi a BRD?

its a BPW :)

[apf]

I currently have a BRE engine with an AWD drivetrain swap that is just asking for a swap like this, so...

[Lucian189]

Good progres :)

[Julian Aksnes]

Full flex hone and new Mahle piston-rings :)




Before


After


Sachs 707 pressure plate arrived. Will work nicely with aluminium flywheel and 4puck disc :)


Coming together..


Headbolts torqued to spec


Havent timed up the timing belt yet, but its starting to look like an engine

[tankdeer]

Looks great!

[jbain2]

So clean. Keep up the nice work
