im just givin a safe zone. thats all..im not sayin im 100% correct .. i said 240 give or take a few...and most?...1 yr?...thats not very impressive honestly..im just tryin to give this guy a area to run his car without worryin to much..i mean say hes the one time(since most have made it some havent) that 250whp..is to much..and he blows it..now hes out a motor..im just givin my opinion..go turbo..push about 10psi..until u can build a forged bottom end..thats all...no one can say there is a 100% guarantee on anything cuz thats NEVER the case..just cuz one motor can do something doesnt mean the next will..anyway goodluck on the build..try to be smart about this..dont push the motor to far stock..get the extra hp now..but build up something for later to push more hp with more reliability....and this is my opinion only!
