Re: b20 V-tec Stats (Coolero)
Ummm . . .
You do realize that there are no official numbers for an engine that was never offered from the factory, right?
What you get on the dyno is what it is, and that will depend on a lot of factors, including but not limited to the pistons, head, bolt-ons, and fuel injection tune being used.

Re: b20 V-tec Stats (Targa250R)
u mean stock b20v???? well im gonna do what others wont and throw out ballpark numbers
B20Z BLOCK/B16 OR GSR HEAD = ABOUT 170WHP AND ABOUT 140WTQ
B20B BLOCK/B16 OR GSR HEAD = ABOUT 160WHP AND ABOUT 140WTQ
with quality bolt-ons ofcoarse and 2.5 in. piping u can get a few more horses out of it

Please explain to me what a "bone stock" B20-VTEC is.

It's not "stock" and never will be. Nor should you slap one together "stock" either. Using the B20 rod bolts and any stock ECU program is just pointless.
There are way too many variables. As I said before,

This isn't the place for bench racing. If you want to find out, build one and dyno it.
Otherwise, look through the All Motor forum dyno thread: https://honda-tech.com/zerothread/1583606 or search in Hybrid to get an idea of what others are getting out of their builds.

If you're only revving to 7000, then you will likely never have a problem. The stock rod bolts can handle that.
But I personally don't see a point in building a B20-VTEC to only rev it to 7000.

well this is on my daily driver and this motor makes great power at low rpm's so im not crazy about revving high... trust that if i had a daily driver my b20vtec woulda been built like you said but dont say that a stock b20v wont hold up... it all depends on your approach (i even bring my car to the track for some fun runs every once in a while)

Good luck with that.
I've never seen a B18A/B or B20B/Z bottom end with stock rod bolts last more than 20,000 miles revving to 8000+ without spinning rod bearings. No amount of "build em right" is going to keep the dinky stock rod bolts from stretching under repeated high-RPM stress.

Last time i checked, B20's didnt come "stock" with VTEC, lol.
For future reference, whats the average lifespan on a B20/VTEC build, leaving the bottom end stock? Last i checked, b20 internals arent fond of the high rev's of VTEC.

wtf are you serious? i've seen a handful with no problems.. yes spinning a bearing does happen more with an LS or B20 bottom end than a b16 or gsr.. but its not like if you rev it over 8k it will instantly blow up... i've driven a b20vtec and revved it to 9k+ (built head) for fun.. my friend drove it for 2 years, still no problems to this day..

Would you recommend replacing rod bearings and girdles for a safe 9000rpm B20/Vtec? Or are the rods weak in there motors as well?

Just wondering, what exactly are the differences other than the P8R head in the B20Z in comparison to the B20B? I was told the headgasket was the only thing increasing the compression? Are the pistons actually different?
As for my B20 build, I'm also had the redline set to 7,200. I will be daily driving it, and have a B17 head (aka B16) with a soon-to-be port and polish and I/H/E

just curious, i have a ek hatch that i' struggling to see what swap i want, and ive been considering b20vtec.. curiosity on track times i guess.
ALSO, what all would one need to turn a b20 with b16 head to around 9grand without problems, and trap low 13's in the quarter?

it is very easy... all u need is a mild all motor build that last stock b20v that i was mentioning was my last setup.. my new b20vtec setup the block has 84.5mm rs pistons, eagle ls rods, arp rod bolts, and new oem bearings thats it!! and my head consist of cams, springs and retainers and new valve and cam seals thats it.... im running 13 flat in an ek sedan!! and yes the car is my daily driver its about 12:1 compression so all i gotta use is good gas and im good i just beat the crap out of it and it will never go with the tune i have and the 9k redline i have

The P8R came on only select models of B20 with the advantage being slightly larger valves. Not all b20Z's came with that head, mine has the P75 head. The B20Z, or jdm spec 1999-2000 model B20 had the higher compression pistons giving a stock hp rating of 146hp, and a healthier, higher reving powerband over the older lower compression B20B models.
