another interesting trend I have noticed is that D-series mock B-series before Vtec just like H/F series model before Vtec switch.
Ok so what? Well D's modified with High comp-ratios and full port work can out perform on the dyno stock B's by a far margine.
Taking this into concideration is it wrong to theorize a fully built High compression (10.5-11:1)SOHC VTEC F22/23 could out perform a stock H22 the way a D16 SOHC VTEC outperforms a stock B16 Vtec?
In teresting to note b/c of the D-series longer stroke low end torq is better then that by a small margin of the B16.
These graphs can be constructed from actual wheel dyno graphs from Import Tuner and JG Engine Dynamics web sides if anyone cares.
I would think the problem you would run into is that a SOHC valvetrain is not good for high revving and will limit how high you can rev. Granted we are talking about beefing up the internals, but given the cost of all this it's probably much easier and reliable to do a swap. Another thing to remember is for most of us we have 100k plus on our motors, I rather have a lower mileage h22.
