The B20VTEC discussion thread

[delsol9000rpms]

so when of any of these built b20s going to do the 1/4 mile and prove some performance figures ?

i would imagine the performance , to be somewhere inbetween a standard b18c7 and a standard k20 (in the same chassis)

i know, alot of talking and not enough walking

well.......this topic started on PEAK power numbers and costs to achieve so.

But , like all things these arent entirely relevant as the gearbox takes over a cars performance more than anything.

I know for a fact , a mate had a b20 "setup" in his eg like 4 years ago and liked it alot. It was actually really fast. He sold it to a guy and it blew up soon after (from what i remember)

lol
anster don't be so concerned about figures. seriously.
going from stock b16 to b20vtec w/ cams will be a hell of a step up and you're gonna feel it when u put your foot down!
saying you're gonna do 'cams' and I/H/E leaves the assumptions and estimations pretty open - at least specifying what sort of cams will make a big difference. there's more than one or two options you know?!

im thinking toda cams and cam gears. im just curious of performance it should produce as this is the first time working on a honda. usually work on nissans and mazdas.

all good. seems to be an avenue that hasn't been explored here a whole lot so i guess there's not too many people to comment.

anster a stock b20 should be around 120kw, with cams, intake manifold, throttle body upgraded maybe around 140kw..

as kraiye said b20's havent really been explored much in australia. there is one dude that made around 180kw out of his stock sleeve B20VTEC, and if your saying his dyno read high, he ran a 12.3 Second 1/4mile in his DC2 Chassis, for more info heres a link. ill see if i can find a video of his run.

Then after he sleeved a block to 86mm (golden eagle b20 block) stock 89mm b20 crank
+more mods and made 260hp and ran a 11.9 second 1/4 mile DC2 Chassis

12.9@108mph, 2.1 60ft B20vtec (V2 spec) @ 144kw EG chasis

13.4@103mph, 2.0 60ft B20vtec (V1 spec) @ 123kw DC2R chasis

13.6@103mph, 2.1 60ft B20vtec (V1 spec) @ unknown (road tuned) CRX chasis (fuel pump issue)

*Estimated time from last year BYP B20vtec @ 155kw's based on circuit data on straights line speeds and acceleration mid to low 12's (possible 11's with slicks) @ 112-115mph

[grumpy rooster]

I hate to burst your bubble but there is no way it would run an 11, even with slicks unless the car weighs around 800kg.
