What pipes did you use to link the;

Airbox to Turbo

Turbo to Intercooler

Intercooler to Manifold

Ive decided to Electrify my 2.5tdi installation rather than Mechanical control but want neaten up the whole engine bay at same time

I had a chance to take couple of pictures of the new airbox setup.
Lucky for me the 2.0L Euro engine uses the same kind of MAF but installed backwards:

Turning the lid 180 degrees allowed me to use it in my setup.

It is very close to the intake, but fits where it touches as someone would say.

Car is running better than ever and I am having a blast with it.

MAF to turbo is custom, 90 dgree silicone hose to Alloy U piece and then stock 1T turbo intake hose.
Turbo to intercooler is a stock 1T turbo to intercooler hose.
Intercooler to intake is an Ur-q turbo to intercooler hose..

I have a bin full of hoses and just pulled what looked like it might fit and it did...

Hi Martin.
Projects update ?

ralleyquattro · **Posted:** Mon Nov 20, 2017 9:13 am

No real project updates... simply running as a dily.
Back to winter mode operation

I am so jealous, I want to do this so badly to my 5000q.

Nickel_5000tq · **Posted:** Mon Dec 18, 2017 9:51 pm

Hi Martin.
The project still running. Good.
I got a cad military truck with 4ctl mec injection. Would try install an electro tunable pump.

It has been a great ride, but I need to move on.
Car is sold and moving onto a new owner.
I hope its as good to the new owner as it has been to me.

Who bought it, Martin?

ralleyquattro · **Posted:** Wed Dec 27, 2017 1:01 pm

Local guy, I am sure we will see it again at local events.

I'm devastated. But just pushes me to find my own engine to do my own TDI swap.

New owner dropped by on the weekend.
I never had the balls to go muffler free... so he did.

Oh, if I only knew it would sound soo good before.

You did a la my A6 wagon

unless you never heard it

ralleyquattro · **Posted:** Tue Jan 23, 2018 8:47 am

I didn't... the new owner did.
And yes, your wagon sounded great with just a resonator, this is straight through!

Sounds great!

Still work on the green avant Martin ?

ralleyquattro · **Posted:** Sun Jan 13, 2019 10:39 am

Yes, work is progressing. Slowly but at least I know where it is.

On a related note the 90 blew up its engine.
#3 cyl dropped a valve.

Broke the injector and cracked the head.
I have a chance to buy it back but not sure if I want to bother.
It would make a perfect S2 sedan copy.

Nickel_5000tq · **Posted:** Sun Jan 13, 2019 6:08 pm

Sold the 80Q

Import the wagen is in your project ? :roll:

I have space here :-)

Facebook page for that project Martin ?

ralleyquattro · **Posted:** Tue Jan 15, 2019 5:19 pm

No, but the 90 tdi might be returning to me. If it does it will be going AAN this time.
The 80q will remain the only diesel project I will be doing.

ralleyquattro · **Posted:** Sun Jan 27, 2019 12:10 pm

Back in the fold.
Not sure what will become of it.
Would like to keep it running as the chassis is still super clean.

Nickel_5000tq · **Posted:** Sun Feb 10, 2019 8:32 pm

Too bad if the wagen does not contunue.
AAN is really good engine. Would make it really impressive.
Still have 90Q. Would love a 5cyl in it. V6 not really good.

Nickel_5000tq · **Posted:** Thu Feb 14, 2019 8:07 pm

The diesel engine passed away ?

ralleyquattro · **Posted:** Fri Feb 15, 2019 1:56 pm

Engine is gone, but the block and crank are fine.
They are for sale.

PRY4SNO · **Posted:** Fri Feb 15, 2019 5:17 pm

95.5?
AEL or AAT?

95.5, yes
1T block, so same as AAT.
Only difference in later AAT/AEL blocks is the location of crank position sensor and matching ring on the crank.
