TFSI Engine changes

[Bikerz]

I been googling for last hour over the changes made the the TFSI engines as the newer ones are better on fuel and lower on emmsions 197bhp upto 208bhp. I cant find any details about this though. When was the change over year? What are the engine codes? Also intrested in the 1.8 TFSI too.

Cheers

the 197bhp engine is the older EA113 engine

the 208bhp engine is the newer EA888 engine (it is also available in 197bhp form in the facelift A3). it is a completely new engine design, right down to running an IHI turbo instead of K03.

as a rule of thumb, European Mk5 GTIs are the EA113 engine. Mk6 GTIs are the EA888 engine. (this does not apply in the North American market, where the MY08 model year was the Mk5 GTI with the EA888 engine)

to make things more confusing, higher output versions of the TFSI engine in later cars (i.e. the LCR, S3, Golf R and Ed35) all use the older EA113 engine with a K04 turbo

hope that helps

Cheers. Im getting a mk2 TT TFSI. So was wondering what engine was fitted to these? Ie should I look at getting a later one with 208bhp? Are they alot better?

Also, to add to the above, the Mk6 Golf 'R' uses the older EA113 engine as used in the Mk5 GTI! Must be superior (stronger?) in some way to the EA888!

Just found this on Wankipedia:

"the 169 kW (227bhp) and higher versions have stronger pistons and gudgeon pins, new rings, reinforced connecting rods, new bearings, reinforced cylinder block at the main bearing pedestals and cap, new lightweight aluminium-silicon alloy cylinder head for high temperature resistance and strength, adjusted exhaust camshaft timing, increased cross-section high-pressure injectors, 1.2 bars (17.4 psi) (value only valid for Audi S3(8P)) boost pressure K04 turbocharger with larger turbine and compression rotor (S3, Cupra, GTI Edition 30), of which some components are NOT shared with the lower output variants"

all pre-facelift 8J TTs are the EA113 engine

some of the earlier facelift TTs are the EA113 engine, but the later ones are EA888 - i'm not quite sure when the cut off was. (of course, this does not apply to the TT-S, which uses the EA113 engine exclusively to date.) basically if you're going to view a car, if the car has the oil dipstick at the front it's EA113, if it's on the left hand side of the engine it's the EA888.

in terms of which is better, the EA888 is apparently more refined, and has better fuel economy as you've mentioned. but if you want to modify it, there are more parts available for the EA113, just by the nature of the fact it's been around longer. some commentators say that the newer engine is too refined tho, making the Mk6 GTI a little boring.

i'd say test drive both and see which you prefer

So does that mean there's a difference between the s3 and ed30 ?

Think they are only talking boost pressure difference...

Does anyone know engine codes or old and new 2.0 TFSI?
Sub39H - What year do you call the facelift?

http://en.wikipedia.org/wiki/Audi_tt

if you scroll down to the 8J it lists the engine codes 

Sub39H - What year do you call the facelift?

quick glance on Autotrader indicates MY10+ cars are facelift cars. so maybe all facelift cars were the EA888 engine 


also if Wikipedia is to be believed then the latest ones have the same trick valves as the A4/A5 - which means you'll get 305bhp from a Stage 1 remap
