Ok - thanks you very much for the advice (Your English is excellent too!)
I am going to build this:
90.5 Cylinders - 1776
32/35mm Valves
Hydraulic Tappets
Camshaft 025109021B Standard +-0 Original WBX 2,1l DJ, MV (For tuning, a 275 degree camshaft with 8.3 mm stroke, which also works with hydraulic tappets)
Balanced
Manfred 1804X Chip
I am hoping Manfred can confirm this configuration will work with 1804X chip and then I will start work
