Is a TT225 engine a direct swap for a B6 1.8t ?

[Luxus Panzer]

Curious....I may be able to find one.

[jesse500]

The engines were transversely mounted into the TT's. K04 equipt motors (AMU, APX, BAM, BEA I think were the codes used) had forged pistons (20mm wrist pins alike AEB). I think same crank, but stronger rods? I also think they had a bigger port head, also alike AEB. But due to them being transversely mounted, I doubt it would be a plug and play ordeal, but I cant see them being much different. Youd most likely have to strip it down to the block, and add all your snub, motor and accessory brackets, hosing, coolant lines, etc....

Physically the blocks are the same however the thermostat housing orfice in the block is machined differently.Many differences.Oil pans are different.Can it be done yes!!Just know you gonna have to swap alot of parts from the original engine onto the tt engine and make some modifications.

180hp tt forged rods only
225hp tt forged rods and pistons only.

US 1.8T is AMB engine code. I think.
Isn't B5 = AEB with stronger head or something?

Is TT like the red-turbo-badge more powerful BEX, in Europe?

There's at least a few threads on that topic but unfortunately I haven't read them yet.

All I know is that my stock AMB is pretty slow.





Side-note. Interesting, pic 2 shows the above blue B6 as having firewall insulation pad, which I've seen in B7 A4's. I think RS4 too, maybe S4.
Yet I've seen no B6's myself, with it. Wonder why.
Same goes for underbody insulation. My bellypan is just that, a bellypan. Meanwhile European cars seem to get added sound-blocking cubes on their bellypans, maybe glued on?

ANY 1.8 is going to be slow, treat them for what they are decent powered, good gas mileage luxury highway cruisers that have some pep once they are rolling.

No 1.8T got forged rods. Just compression cast. AEB & tt225 got 20mm wrist pins, where the rest got 19mm. No 1.8T has a forged crank, same tight compression cast unit. AEB/AWP/TT225 got forged pistons (20mm wrist pin).

True about 1.8T’s not having forged rods. Crankshafts are a little different though...

1.8T crankshafts come in different flavors. This is an attempt to classify them.
The main and rod bearing sizes and flywheel bolt patterns are all the same.
To the best of my knowledge, this information is correct for US model cars
There are 2 main categories
058 Old Style- Came in the 058 external waterpump blocks only in longitudinal cars.(A4, Passat) These all have the “short”, small diameter snout. These cranks are all cast, and come with a toothed 60-2 wheel
There are 2 versions
Manual – the difference being the spigot on flywheel end. These have a pilot bearing pressed into the bulbous spigot on the flywheel end.
Automatic- This has a much flatter protrusion on the flywheel end and no provision for a pilot bearing.

06A New Style- These came in all 06A blocks with internal waterpump, both longitudinal and transverse. (Some codes AWD, AWW, AWP, AMB, AMU, AWM) These all have the “long”, large diameter snout. These cranks are cast or forged depending on application, and come with a windowed 60-2 wheel
There are 3 versions.
Transverse manual/automatic- These are all forged and have provision for a pilot bearing to be pressed into the bulbous spigot on the flywheel end, but no bearing is installed.
Longitudinal manual- These are all cast and have a pilot bearing pressed into the bulbous spigot on the flywheel end.
Longitudinal automatic- These are all cast and have a much flatter spigot on the flywheel end and no provision for a pilot bearing.

Application Notes:
058 and 06A cranks are not interchangeable- they must match the block.
Transverse applications can use any of the above listed cranks.
Longitudinal manual applications can use the transverse forged crank with the installation of a pilot bearing. They may also use the longitudinal automatic crank if an adapter is machined to accept the pilot bearing.
Longitudinal automatic applications can use the transverse forged crank, or longitudinal manual crank if the spigot on the flywheel is machined down to clear the torque converter.
Trigger wheels are physically interchangeable, but must match the sensor/block used.

I had no idea they were transversely mounted , thought that was just a VW thing.

Thanks for the info all, I think I will pass.

No 1.8t got forged Pistons!! They have a higher silicone content but are still all cast.

Um, no. Not sure about AMB, but AEB/ATW/AWM all have forged Mahles

[EuroxS4]

Nope definitely don't AEB for a fact does not.They have a higher silicone content which makes them stronger.They are still cast and stamped though a series of dies,but are not a true forged piston.

Can you back this statement up?

[EuroxS4]

Sure google it or look up 058 engine up in the wiki pedia

First gen TT's are basically a Golf 4. They have a lot in common. They are same (VW A4) platform. As is jetta, new beetle, first A3...

Tell me if this makes sense.They are telling you "some" engine codes had forged Pistons but don't specify which ones and also tell you that they are not designed for high power levels correct??Hmmm sounds like a good way to sell some Pistons.Also they say most 058 cranks are cast which is true they mention some were forged,which is false.Cant use a 058 crank in a 06A block.Some 06A cranks were forged true.

Long story short can't believe everything you read.Stock Pistons are good for power as long as you limit the knock and detonation,and upgrade the wrist pins to tool steel.


If you want to believe everything a performance company is telling you and is trying to sell you sure be my guest.Its kinda odd that they list the part numbers of products in that guide as well but I'm sure that's not coincidence.Dont get me wrong they make a lot of good products,but don't believe everything you hear.

You are wrong in some instances.Very few and good luck finding one.NO AWP engine ever had 20mm wrist pins they were all 19mm.But no pistons were true forged pistons they are manufactured by Mahle and are pretty stout if your using aeb,atw,or amu,bea.As they all had 20mm wrist pins.

So Integrated Engineering, the only company that gives two shits about developing quality 1.8t products this side of the Atlantic, is wrong. Got it.

I dont feel like replying cause I can tell its like talking to a child.So believe whatever it is you want to believe.Your the expert with unlimited knowledge on every subject,because your a genius.Please stop spreading misinformation.

Yes, I am very childish. But I also place more stock in an Integrated Engineering publication that some random internet guy's posts.

Dude, they are forged. Just like 2.7 pistons.

Sure they are.Some me some literature from audi that says so.Surely you have a ssp that states it in black and white.

Black and white. And a red cock because I am childish.

Clearly says 2.7 genius not a 1.8T.But the drawing confirms my earlier suspicion.

You have that backwards. your earlier suspicion is the reason for the drawing. Call me childish and you'll get red dicks. Might as well live up to my reputation.


So, I showed you a publication by a highly regarded aftermarket 1.8t company that made their name modifying those engine. I also showed you factory literature stating the 1.8t's sister engine, which is essentially the same thing, has forged pistons. I could also turn up ass tons of threads stating the same. And you still don't believe me.

Who is childish now?

Like I said clearly a child 2.7 and 1.8 are clearly not the same engine.Just quit now it's getting boring.

I asked you to show me a 1.8T ssp from audi that's states what your saying.Clearly you must suck at math,are blind, or can't distinguish letters or numbers.But then again you must be a millennial which would explain everything up to this point.

It's like saying a red light is the same thing as a green light and they mean the same exact thing.

LoL

[jesse500]

this went well

[audireme]

Spike00513, my B6 A4 cabrio has the insulation pad. But I haven't seen it on sedans/avants either.
