I am planing to rebuild my BEX engine( bearings, piston rings...) and put on maxpeding conrods with AEB pistons
Will be any benefit to put on AEB big port head? For now my plan is K04-023, later maybe something bigger but not over 350-400 hp
Second question can I put ADR (1.8 N/A) camshaft in engine with AEB piston? I am asking beacuse i see that ADR have bigger chamfer on piston for 5-th valve than a AEB piston.

You can, the cut out is bigger because the compression height/cr is is higher since they are flat top pistons.

If u want use aeb pistons, use 2.0 tfsi axx/bwa connecting rods. Its cheap and dont have problem with align like chinse shit "forged" rods. They easily handle 500 nm. I use AG cam from adr engine and i have vvt enabled to 5k rpm without problem.

I have both pistons too, perhaps I shouldve worded it different, the compression ratio is not the same, since the turbo pistons are dished, including some area where the chamfer is, the edge chamfer is the same you can see it on the pic. Point is you are fine since my OG engine had na pistons with na cams and vvt, and im currently running those pistons with vvt anyway.
Also 2.0tfsi bwa rods are trapezoidal small end where as aeb 20mm pistons are straight.

So I put maxpedding rods and AEB pistons, new piston rings and new crankshaft bearings
Head remain stock BEX but camshafts are from N/A engine, both intake and exhaust
Results? As far as now i can see I have lost power in all RPM range. Have less boost and about 6-7 g/s less than before
I will check everthing one more, but I think I am going back to 1.8T cams

I read that people only put intake camshaft from ADR. And it work better with bigger turbo than stock k03.  |

We have great results with N/A cam on big turbo setup BW S200SX-e.
At 2.1 bar we have 500 hp at 16 degree timing on 7600 rpm
