HP Differences Between B20VTEC and B20 NonVTEC?
Hey guys, since some of you guys have B20VTEC in their CRX.
I was wondering how much more HorsePower does the B20VTEC compared to a NonVTEC B20? Is it true that VTEC gets in the way when it comes to boosting?

No, VTEC is a good tool to have for boosting. Allows us to stay safe in higher RPM.
The CRV engine by itself is going to produce a good chunk of torque - the CRVTEC gives you the higher redline, and horsepower curves with the reliability of one of the stronger blocks Honda has made.
You could get impressive results out of boosting just a B20B, its perhaps what my next motor will be.

yup me to.
The real question is, will it really last? Can the NonVTEC block handle the VTEC with stock internals? Because I want the motor to last on me and not just blow up like Jeff last LS/VTEC motor.

vtec is bad for turbo b/c it leans way out at the crossover. if you have good fuel management it's easy to correct for this.
all vtec is is a hot cam. more lift and overlap.. many ppl are successful with turbo vtec's.
i dont think that the extra 30 hp from the vtec cam will stress the block much more than the boost will. unless the vtec head raises the compression a lot you will be fine.

golden eagle, buy a whole dart closed deck block, or you can do endyn posting (cheaper, easier, better).
jeff's blew up b/c he cranked the boost to some crazy number like 14 on stock sleeves.

Re:HP Differences Between B20VTEC and B20 NonVTEC?
but usually can nonvtec blocks handle the VTEC? I have known so many people around my city that has LS/VTEC, B20VTEC stock internals. And they usually dont last 3 months. Why is that?
