B20 crvtec good for FI or not?
is the b20 vtec setup with b20 rods and crank good for forced induction? i heard the poor rod length ratio doesnt go along with FI. is this true?

it's not the greatest, but it does have a lot of torque. Remember not all of us can afford the build the ultimate motor. Just build one and have some fun

my friends got a B20vtec in his civic coupe, its pretty f'n fast.. I cant imagine it with a turbo on it and hes going drag 3 soon.. I cant see how it could be bad for turbo since its already such a powerful set up on its own..

oh my lord. How fast you making with the crvtec turbo ? got damn!
the crvtec alone is the fastest NA motor and torque monster you can make. With turbo I bet you have a hard time getting traction threw 1st-4th gear huh

yea id say B20 is a really good motor to turbo. Unlike with b16s or whatever you have crappy low end so in the beginning its sucky until you can get up to speed and have your natural high end power plus the turbo kick in. The b20 has good *** low end so you have a good start and once your up to speed you have vtec, giving you good high end, adding turbo will only make the high end even better, plus the b20 has really low compression which means higher boost levels!

It was a white civic coupe and it had stocks on. My friend's MR2 runs low 13's and the civic pulled on him.

Hi guys, I'm really new to this board, and am just getting into the realm of hondas and stuff. Please don't flame, and If I am wrong, i would like to just be told why I'm wrong, not "ur gay go away".
Umm.. It is to my understanding that the first generation H22A block was a closed deck design, which is superiour for boosting.
I realize you can get a block guard , but if it's there from the start, it's probably a little better... dont forget that it doesn't have the greatest rod to stroke ratio in the world, but all the high horsepower super fast guys are using them..
I think a correctly CRVTEC block would be able to handle a good amount of boost, while still allowing to fit into many chassis much easier then a prelude vtec engine.
I know quite a bit about boosted cars, but i'm more known in the nissan world.
ive got a 300zx turbo that has already hit mid 12s on shakedown runs that i built from the ground up at age 18, and it's using stand alone fuel managment systems courtesy of sds - http://www.sdsefi.com - . I would love to help out fellow forced induction guys as I feel it's the only way to truly make up for the loss in cubic inches.
I think the most important thing to consider when doing a CRVTEC is upgrading your rods and pistons to make them stronger and keep that compression ratio down. A T3 Super 60 would probably work wonders on that motor.
I see easy improvement over the SR20, especially with the vtec lobes.
