cause they don't know how to build and tune an engine?

CivicSiR

So how do you properly build one and tune it?

They all went to shops that build it for them.

But usually how long will LS/VTEC, B20VTEC last?

rextec

you need a b-series vtec oil pump i think this is a biggie that some shops just may not do, leading to oil starvation thus blowing up. if you build it right and dont just throw ---- together it should last as long as any othe honda motor.

CivicSiR

well since i have a B16a motor sitting here. I can just buy the B20 bottom block. And use the LSD B16a tranny.

One big reason crv/lsvtec only last about 3 months is because people put the vtec head on and think they can redline it at 7500+rpm when the motor shouldn't be taken past 6500 with stock internals.

jeff revs his crvtec to the sky everyday. even i did it. watch the bbq video lol.

the rod stroke ratio is bullshit. maybe on a racecar engine that has to runs 9k rpm ALL THE TIME. like constantly for 500miles or whatever.

hey random-strike, was that you driving that Jeff Honda CRX?

Hey, ask the guys why their motors blew up the next time you come acrossed them I am kinda curious to see whats up.

If you want a reliable motor, especially one you're going to boost, don't be cheap about it. Take your time to build it properly, I have learned that this is the way to go after having spent $4k on my Del Sol and blowing up one motor while not having a job at all :P

CivicSiR

when you say properly build. Do you mean changing all the internals?

Chacko

yes, having it resleeved, oil channels enlarged (if possible), upgrading head internals, using stronger connecting rods, and pistons.
