Roughly 15hp.

Different cylinder heads to be sure, not sure if the blocks are different. Could be, as the B series without vtec vs ones with are different with special oil feeds in the block to get to the vtec solenoid on the head.

I believe your '01 Accord has VTEC?

As multi-valve technology has became the standard in modern engines, so will/has variable valve timing. VTEC is Honda's very own type of system. Just about every manufacture has there version these days.

With the timing of the intake/exhaust valves power and torque can be optimized accross the rev range.

One of the most notable is Fiat's Barchetta coupe, some 90% of its peak torque is available from approximately 2,000rpm to 6,000rpm, and this is on a naturally aspired (not turbod or supercharged) 1.8- liter engine! It also makes a noticeably interesting sound when it fails

1) I believe the DX model did not come with variable valve timing

2) peak torque on the V6 is at nearly 5,000RPM - Honda makes screamers

The DX and VP did not come with VTEC engines.

To be honest with you, the non VTEC 2.3 feels more powerful around town at lower speeds than the VTEC variant. I believe this is due the the VTEC motor requiring more RPM to do it's magic, where the non VTEC has more Tq lower in the RPM range.

I could be wrong. I am going off of comparing my 99 Accord (VTEC) to my 96 Accord (F22B2 Non VTEC) and a 01 Accord VP (non VTEC) that I have driven back to back.

Sounds like nothing a K20/K24 can't do to me...

They both make 90% of peak torque in about that same range.

I've never heard of a Honda valvetrain system failing before

I guess it can be with Honda's expertise and cam phasing.

Well, I was more or less referring to just to 90% of peak torque-blah-blah-blah...


But I have seen some interesting Honda motor failures in my time.
