TDI120: My New Engine

[kiklop123]

What about petrol cars. Can the engine AUA be changed with 1,6 FSI?, or is it much easier just to replace it with new AUA. Found one new on ebay;

MIne is having 210000 KM and is leaking oil + the noise it makes while running reminds on diesel engine.

This would require loom work the internal loom is different on the 1.4i to the 1.6fsi it would be a massive job

Hi Tom,
I've just caught your amazing TDI story and the lengths you went to, to achieve it. Awesome ?
Looking to do 'something' of a similar ilk, but certainly no where near as extensive as your project, I was wondering what make/model of Intercooler and Turbo you used? Also, you imply that the Turbo/Manifold swap is just that - a swap? Does the increased Turbo output need the increased Injector capacity or will the ECU/Vacuum system within a standard TDI75 (albeit breathed on by Vince @ Stealth Racing) cope with managing it?
Lastly, the Silicone Tubes used for the inlet delivery, what make did you use and where did you source them from?
I know you posted this many moons ago, but I hope you might have some memories or records.
Many thanks for any info you can give.
Mich

Hi @MichST4,

Many thanks for your kind words.

I was wondering what make/model of Intercooler and Turbo you used?

Lastly, the Silicone Tubes used for the inlet delivery, what make did you use and where did you source them from?

All of these items are custom fabricated. In the case of the intercooler and the silicone hoses, they're only available through me. The intercoolers are manufactured in batches, meaning availability is dependent upon stocks/demand. The silicone hoses are manufactured on demand and are usually delivered within a fortnight of the order being placed.

My right wrist is currently in a splint, and typing with only my left hand is slow and arduous, so please accept my apologies for the brevity of my reply. I shall endeavour to answer your other questions once I have a full set of limbs again.

Kind regards,

Tom

Hi Tom,
Sorry to read of your impediment....climbing again perchance??
Thank you for getting back to me despite your suffering. Regarding the Silicone ducting, I’d like very much to replace my OEM rubber with something rather more exotic. However, and this may be a problem. I’ve a BHC spec engine that has separate EGR and Splutter Valve. The Splutter Valve has a specific quick release/retention clip as a means of connecting the inlet duct to the manifold system. Whereas I noticed with yours, that your combined, albeit modified, EGR & Splutter Valve has a straight on push fit & clamp arrangement. Are these replacement Silicone ducts able to take my setup or would I likely need to introduce a sleeve to join the old and the new???
Whilst you’re chewing on that one, I seriously hope your wrist repairs itself to full functionality and in a timely manner ??
Many thanks Tom
Mich

Hello, about of indispensability of the scoop of intercooler. What is the OEM number of spare of the scoop, my daughter had an little crash and broken and lose the scoop and now the car isn´t have it. I like to buy another but not find any and I not know how locate it.
Where can I buy one scoop and what is the OEM number reference.
Best regards.
Thanks you so much.

I too have been looking for the scoop (or air diverter) for the intercooler. It seems not included in the VAG part system database, I have been asking the local VAG dealer but they cant find the scoop. Luckily @A2Steve kindly could share a picture of a scoop from one of his breaker (thanks Steve) that shows the part number:

Just in case no-one here is able to find one in the recycled parts, Audi Tradition still have them - (brexit & importation duty chaos notwithstanding)

I’ve just read and digested this, Timmus, I was absolutely knocked out by it, what a enjoyable journal of your quest
to do it your way, the thing about it was it was enjoyable as well as informative, envy has also set in, great stuff.

Hi Tom,
I had come across this thread not long after joining the forum although it's not something I would take on myself I just love to come back and read through it again. It shows your passion, professionalism, dedication and love for your craft to which so many other members benefit on this forum not to mention other members with knowledge who help others out on a day to day basis.
Top job and write up.

I've just found this thread this morning, and have spent a very happy few hours perusing the wealth of information held within it. Superbly written, honestly better than the sources I'm citing for my dissertation, and so easily accessible. Whilst I already had knowledge of the inner workings of TDI engines, I've shown the explanations to non-enthusiast friends, and now they all understand what I talk to them about. It's also nice to know that it's not beyond reason that the 'ideal' A2 can be built for everyone, time and funds permitting. An excellent read, and many congratulations on the whole project, Tom.

"I wanted to write an article that would be interesting to those with prior knowledge and accessible to those without."

@timmus Wow - you absolutely achieved the latter- as a total non-mechanical person i feel like i now am beginning to understand how an engine actually works and what all those parts of the system are actually doing and how they work together. I had only the vaguest understanding of what a turbo is and does before. Not only that, I now have a much better idea of what all the various pipes, valves, lumps of metal, and other bits are when i open up the engine compartment of my A2....I now know where to look for the green coolant sensor for instance, and that what i thought was a thermostat is actually the EGR valve!!

On this point, is there anywhere on the forum a photographic guide to what you see when you take the bonnet cover off???

Brilliant, i shall no doubt be returning to read this again...and i like the sound of the upgraded intercooler and pipes

I read it yesterday, very informative, and well set out too.

It's been a while since I've caught up with this thread.

you absolutely achieved the latter

Thank you very much for your kind words. It's been nearly 8 years since I wrote this thread (where does the time go!?) and I'm delighted that it is still proving interesting, informative and entertaining.

Superbly written, honestly better than the sources I'm citing for my dissertation, and so easily accessible. Whilst I already had knowledge of the inner workings of TDI engines, I've shown the explanations to non-enthusiast friends, and now they all understand what I talk to them about.

Thank you for your compliments. At the end of writing this article, I compared it to my own university dissertation (which was about Cassegrain reflector radio antennas) and found that this contains more words and figures. I guess you could say that I voluntarily wrote a second dissertation ...but thankfully this one wasn't done to any deadlines, and I didn't have to submit it for marking.

Top job and write up.

Thank you, Stan and Mac. I'm glad you both enjoyed it.

It has been some years since I've read it again myself. There are certain sentences that don't read as clearly as I'd ideally like; a common pitfall of proof-reading your own work immediately after writing it. Maybe one day I'll edit the odd bit here and there, but maybe it should remain untouched, warts and all.

Regards to all,

Tom
