Default B20 block/b16 head

I met a guy that did a b20 block and b16 head its putting out at least 250 whp he said. It was bone stock....(supposidly) i the thing was quick as hell. He had it chipped in queens. he can easily reving it to 9700. I was so amazed. Has anyone else seen this setup? w/ this much power?

I hightly doubt it had 250whp for one... for two I high doubt it was rev'able to 9700... and for three.. no STOCK bseries motor is going to put out 200whp even....



btw welcome to ht

a stock itr is under 200hp and it probably has under 185whp.... 250whp is just insane for a all motor car

Correct me if im wrong...but i heard the b20 has problems revving...and a 9700 is a hell of a rev...and the 250whp deal...nearly impossible especially stock...

OMFG...it's one of them guys again who believe everything they hear or see.

stock B20/vtec your lucky if you see 175whp.

and good luck revving to 9k+ on that setup. maybe that CHEAP chip will allow him to do that but his internals won't for long.

i have a 1997 crv b20b block with a 1993 gsr head and gsr lsd tranny

when i got my motor out of the shop the technician said that i had 195 hp

stock and i had a ls motor before with 140 hp

we went for a test drive and he said to me : rev your car on each gear to 8000 rpm and i was like : if i do that my ecu won't aloud me to go that high i only can go to 7000 rpm , and then the guy said tried

and i did when up to 8000 rpm with no problem , i think he use my ls ecu and put a chip in it and conected to his computer or something
but now i am running my ls ecu with vtec should i buy a gsr ecu ???

now when i race i feel like 8000 is the most power i can get out of each gear , but i need to do a dino to see exactly where i start losing power anyway i can rev up to 9000 rpm but don't see power after 8500 rpm

Is it just me or is it IMPOSSIBLE to chip a LS ecu to have vtec?

you need a new ecu for vtec... or maybe just a ls with a vafc... not sure tho. but no you cant program a ls ecu to have vtec, its not just the programming but there is no heat going to the wires that are used in the plug for vtec

I have seen it done and at the moment is the fastest civic at the tracks in my area.

I mostly agree with everyone here, there is no way he is running 250 whp in a stock b20/vtec hybrid. Even if he removed the redline, with stock internals his r/s ratio would be way to low. Not only would there be a lot of friction, but without a longer rod his piston would move way to fast around tdc to perform at those levels. This setup could run 250 if he had custom stroker crank, lengthened rods and/or reduced compression height pistons to at least run a 1.6 r/s (which isn’t cheap, and I’m not sure even a b20 has a tall enough deck to support it, maybe a dart b20+), as well as sleeved for strength, and a whole lot of work on the head, but what he speaks of sounds more like a redneck job to me.

The other part of my post concerns a quote by b18Tahtaras, “think torque... it gives the ellusion of power... prolly what you're thinking”. Torque isn’t the illusion of power, it’s a component of it. Quotes like that make me think a lot of people could benefit from sitting in on a physics class. Torque is force times distance. If you take your wtq, divide by the radius of your wheel tire combo, you will get the force at the ground level your car is producing. This force accelerates your care. Power is simply torque times rate of rotation, which is important for two reasons. 1 A Honda with a lot of hp generally produces good torque in the upper rpm’s, and thus can pull a lot longer than a lot of domestics (not having to shift along with lighter weights is what makes a built Honda fast). 2 When you get to speeds where air resistance starts to really matter, in order to accelerate through the friction (if gearing allows for it), the rate at which you engine does work must be greater than the rate at which the air does work on the car.

In other words if you want a quick Honda, you want a flat, large torque curve well up to 8 to 10K.

Any body who doesn’t believe me, simply go out to your car, pop it into neutral, go to a flat spot in your torque curve (the hp curve will be slanted at this point) and push on the gas at a constant pressure. The tach should move at a constant rate due to relatively constant torque. If you hp accelerated you, then your tach would move at an ever increasing rate.

i think that guy is bs about being stock.i think its modded becuase it has to be reving that high. and you do need a vtec ecu otherwise the vtec wont work. ill post some dynos to show what they pull out stock and modded.
