My block decided to fall apart on my 1.8t so im building another. I come across a 2.0 TFSI lump for a good price so my plan is to use the TFSI crank in the 1.8T, i already have IE rods so it leaves me with pistons.. is it possible to use the TFSI pistons?
I believe the standard size piston in the 1.8T is 81mm and the compression is around 9.3:1 (?) whereas the TFSI is 82.5mm and the compression is around 10:1. I understand that on older engines, high compression and high boost is a no no. But is the 1.8T capable of running both?
