Here is comparison between 2.0 TFSI crankshaft 06A 105 021 AR and 1.8 T crankshaft 06A 105 021. Both crankshafts are from transverse engines.
How to know which one is which - 2.0 TFSI is new, 1.8 T is used.
Both cranks are from Europe.
History - there are three part numbers for 2.0TFSI crankshaft : first was 06A105021E, than was this number replaced with 06A105021S, and finaly was this number replaced with 06A105021AR.
Units are in milimeters.
Dejan provided both crankshafts, so thanks Dejan.
My findings are - that crankshafts are identical, only difference is tooth gear wheel for oil pump ! 2.0 TFSI has 21 tooths, 1.8 T has 19 tooths. Part number for 2.0 TFSI tooth gear wheel is 06B 105 209 and for 1.8T is 06A 105 209. Here in Europe we can buy 06A 105 209 tooth gear wheel for around 20 USD. Both cranks have the same diameter where this tooth gear is attached - so no problem at all for a swap. 2.0 TFSI crankshaft is alot stronger (on one photo a pointed out this difference) and it weights 1kg more that 1.8T crankshaft.
I can only speculate that first crankshaft for 2.0 FSI was 06A 105 021 E and in VW Tech documents there is a text that 2.0 TFSI crankshaft is reinforced over 2.0 FSI crank and I think that first 2.0 TFSI were using 06A 105 021 S crankshaft and maybe 06A 105 021 S is stronger than 06A 105 021 E. And I speculate that maybe 06A 105 021 S and 06A 105 021 AR are identicly reinforced.

Re: 2.0 TFSI vs. 1.8T crankshaft (FrankiEBoneZ)

I will buy it in near future and put it in 1.8T crankcase. I allready have wiseco pistons from Dejan for 2.0 stroker so there is no way to go back now.
Dejan managed to persuade our local dealer and dealer orderd this crank and he will return it back to central store (dealer can return new parts here and pay just a small amount of money).
In Slovenia price is around 900 USD, but I can get it from Germany because Germany is close to us and there it costs around 650-700 USD.

Re: (AudiA4_18T)

You just need to use pistons for 2.0 and on 2.0TFSI crank you need to use 06A 105 209 tooth gear for oil pump.
2.0TFSI crank is much stronger than 1.8T or 2.0 AEG.

For AGU engine take 06A105021AR crankshaft. This is from 2.0 TFSI transverse engine, like Golf MK5 GTI. It fits without any modifications in AGU crankcase. You need to buy also 06A105209 tooth gear for oil pump from AGU crankshaft and put it on TFSI crankshaft. Or use old AGU tooth gear and put it on TFSI crankshaft.
