One of my fellow employes tld me that he doesnt liek Vtec because when your engine is cold Vtec wont crack... is there any truth to that...but i sed to my self why does it matter...its not liek your goin to start your car after a winter night an right off the batt race some one...you obviously have to dirve some where to get there and by that time it should (engine) have warmed up... any ideas

 

vtec will not engage unless certain conditions are met. engine up to operating temps, enough oil pressure, over a certain speed, over a certain throttle position, etc.

if your friend is driving hard enough to try and engage vtec when the engine is still cold tell him he's an idiot.

 

no he doesnt have a VTEC engine...he refuses to use a Vtec block...i belive he has a JDM Si crx motor...he told me hes workin on makin it rev out to 1100 rpms...i kinda ignored him on that i figured that past 6000 rpms that motor stops makin power...but i could be wrong...what do u think

 

Just like Snoop said, won't engage when it's cold, etc etc

 

quick question is the only diff between vtec an i-vtec is that the oil can be changed ( in the i vtec) every 10,000-15,000 miles... my boss drives a accord and told me the dealer told him with good oil an with i vtec he could go 15000 miles befor an oil change.

 

you're friend is a moron. plain and simple.

ivtec has the variable valve timing and electronic lift control of a normal vtec, but also has vtc, which allows continously variable cam timing.

 

only 1100 rpms thats tight.vtec all the way why would you want to miss out on a higher lift and duration cam at higher rpms and a nice idle with good low rpm power.best of both worlds.and ya so what it doesn't work cold you don't want to push your engine when its cold.

 

11000rpm*****

 

i stand by my previous statement.

 

i know what you ment i was being dumb.
