hi,
i've been told that 4G63t from evo 1-3 (some say 2G block??) are prone to crack which is not good for high hp application.
yeah i know that evo 3 is a bit high compression..but if change to forged low compression piston but other's like block, conrod, crank, bearing and so on still stock...how many torque/hp is the max before damage ?
ok, after that some people told me..the piston is ok (except for high comp evo 3), but the conrod is sooo weak.
now, if change piston+conrod..and other still stock. what's the max torque/hp before the disaster.
p/s: assuming a/f ratio, ignition timing, spark plug rating all ok
