My mate has just bought a TT with the 180BHP engine, last night he asked me what the difference is between the 180BHP version and the 225BHP, because they are both the same 1.8T engine. I told him I thought difference was probably in the engine managment and maybe the cams, as I think the turbo's on both engines are the same, I could be completely wrong though, so if anyone could give me the definitive answer I would appreciate it.

I'm sure Stu or Chip will know!

Looked at this engine for the maestro.

I think its ecu and turbo, cant remember what reyland said but he did say start with the 225 from the beginning and there good for 350 on standard internals, and in a 800kg car would be a riot

I think its just the map to be honest.

Same with the Golf, Leon etc.

{edit} i'll shut up then.

Thanks guys!

Following on, is it relatively simple to bring the 180 engine up to 225 spec?

i think its just a chip, or ecu change

pretty sure the engines are identical

and good for over 400 on std internals

You may find that the 180bhp engine has a K03 sport turbo

The 225 & 210 engines have a K04 turbo

The maps will be diff also

The 225 is a much stronger motor it can run up 350 bhp as it is the map turbo and internals are all differnt . 225 is a BAM engine.

Oranoco

The turbo is different between the two cars as I have the poverty 150bhp motor. As I get stuff to break though power will be hiked.

cfoster

Not sure on the exact differences but my missus' 225 TT kills me mates 180 every time!!! It may be the turbo as said above and possibly the ECU.

Trist

ask power engineering about it as I seem to remember them having a mess up with one. I am sure the pistons were different and whenthey bolted all the otside engine parts from a 225 to a 180 it went pop. remember chris todd telling me about it few years back when I was there getting a car set up.

Ryan

im think, its Turbo, inlet, ECU, injectors,

Differences are: Comp ratio, Pistons,Turbo, Manifolds,Intercoolers,
Injectors, Obviously Map plus maybe crank/rods.

225 has 2 intercoolers one each side of the front bumper

Hence the reason why I mentioned 'intercoolers'

Don't the 225's need very expensive oil or higher grade oil too?

GARETH T

selling and buying a 225 is the best option

As martin said also the downpipes are very different so bolt on a ko4 to a ko3 engine requires work.
Not just a straight swap.

the 225 has 9.0:1 comp ratio the 180 is less.
there are lots of small changes between the two.

Martin-Hadland

iTrader: (2)

The 225 is indeed 9.0:1 but the 180 is not less it's 9.5:1

very true - my mistake

Just to add to this fountain of knowledge......

Wazzzer

so from what I can see on there would it be worth searching for an AUM managed car to get the K03s and the larger injectors for mine, then a remap?

AndyNo1

No, you wanna get the a 225 Audi managed car with the bigger turbo and injectors etc

Wazzzer

yeah but I want something that's bolt on rather than having to mod the downpipe etc for the K04

AndyNo1

Then yeah...

M7 COS

Thanks for all the replies guys! Lots of good info there.

my girlfriend has the 180bhp A3 quattro

we're going to get it chipped at a audi tuning places in bromsgrove begging half of august

Ł300 n they claim to get 225bhp roughly

Stavros

was gonna say, contrary to popular bullshit, they very different, its not a Mini One/Cooper scenario there.

but ive been beat to it, massivley

wayneclayden

Yup It certainly is a riot!
I have one in my Elise
