mk3 tt & tts engine differences

[prevedinterned]

Hi folks

Anyone know differences of tt & tts engines ?
I know that they based on 2.0 tfsi but what about turbo charges, cooling system and etc ?

Although I don't have the specifics there are quite a few differences, as you would expect to be able to provide the additional 72 Hp. Larger and more robust valves, stronger materials for pistons/connecting rods, larger intercooler, higher throughput turbo, etc.

I'm going to guess it's the same differences between a3 and s3.

Bumping this just to not start a new thread. But exactly what differences do the motors have?

[kevin#34]

as far as I read, bigger turbo, different pistons and camshafts + few other minor parts

There quite a few differences depending how you look at it

The biggest difference or most noticeable is the turbo

Aside from that they still share majority of DNA and ultimately 2.0L displacement 4 cylinders

If you want the nitty gritty stuff

-Pistons
-Rods
-Cylinder head
-Camshaft profiles (depending on year also the valve lift system on one of more banks)
-Additonal gurdle for block strength
-turbo
-hpfp
-Injectors
-conrod bearings
-water pump (impellar differs for more flow)
-Aux cooling
-intercooler size
-SAI system (tts uses strictly valve timing where others use sai pump - ***for most NA MARKET from what i seen, engine code differs example CALI***
- transmission and rear diff final drive ratios
-transmission mechatronics for LC and shifting
-Exhaust (after DP)
-brakes ***front and rear***


(Off the top, couldbe missing a few things)

There also some other minor changes but can also differ with options on car selected like mag ride, interior colouring, wheels, spoiler ect ect
But some of these things also vary from market to market and options vary as well

(Pure example is ealier gen cars 17-18 with comp pack sold in usa vs canada, canada got the tts bumpers and skirts vs usa didnt in the same package)


The nice thing is majority (im gonna guess this at 70ish %) is interchangeable between the two i.e literally bolt ons based on the highly similar DNA


If your asking this to make an overall choice, honestly they are so similar that literally imo, comes down to what spec when you find one tickles your fancy, budget, and overal what you want to do with the car goal wise


I was in this same situation with the wifes car choice between a TT, TTS and base cayman

Ended up finding a good middle ground by getting a TT sline with competition package
-no regrets

It was 8k ish cheaper than a TTS (out the door after taxes at the time)
Had all the cool bells and whistles, had the cool looking package with fixed wing and bumpers ect, and the standard consumables were cheaper knowing this was a daily driver for long term with mod potential and she does so much driving (25-30k a year) that it was more favourable cost of maintenance down the road

We sacrificed overall power for long term having fun and being a little easier on the wallet knowing maintenance was going to be more frequent based on her driving ( example being brakes - smaller on her car vs tts and say 700$ to do all the way around vs 1200$, fuel economy also a tad better which long term for her adds up to roughly 700-800$ cheaper per year based on the smaller turbo and overall output)

Fast forward 3years and a bit later, its tuned and slightly quicker than a TTS and still less money.

Dollar for dollar, yes a tuned modded TTS will go further, but bang for buck overal, the TT S-line fit the bill better for savings and similar experience

If we were to redo the same thing, we would still go the same route (new atleast), however, in the used car market now, the TTS might be the better buy for not much more in comparison when new


Hope this helps
