for me, the best is using 4G93 block & conrod with 4G94 crackshaft. the problem with using 4G94 block is, it's tall n u need to use the 4G94 conrod too and this conrod is quite thin. not suitable with highrev + high compression. the only advantage with this setup is it will generate less load on cylinder wall. i used to know one mivec with 4G93 block + 4G94 crankshaft, stock mivec ECU (rechipped) + VAFC, stock mivec intake achieve 220bhp on wheel with very hi torque (dyno dynamic) .
ok you prefer option 2 . wow 220bhp on wheel is a great hp man this is awesome! the information you provide are really useful for me! if in future i've any problem i will pm you about it .
Cheers and Merry Christmas!!
