Hej! how much boost/hp stock m50 connecting rods would handle(135mm) ?
Want to get near 400hp with 2871 or other similar turbo . Bored out to 86mm with sr20det pistons. m47d20 crankshaft(88mm) and planing to run 10:1 comp with E85, vems. Now I doubt they would be capable to handle high cylinder pressure. What is weakest part - bolts or rod?
I know it depends on tuning, but still... Any thoughts?
