B20 Internal work

Hey all I wanna pick up some extra ponies with out resorting to turbo. Right now i have a B18B1 block and a B20 head. So What cams will fit the B20 head? Any websites? or can I pick up some ponies by puttin in a cam from another engine? And what kinda pistons can I put in the B18B that'll give me some ponies. I have about 500$ to work with. What internal work can I do to this set up with these funds? thanks.

i use the cams that cam off my old b18. work just fine. so anything that will fit the b18 will fit the b20.

if u wanna go with a cheap but yet good setup that will net u around 12 whp, then go for the crower 62402 cams. these dont need upgraded valve springs so thats why it's a cheap setup. should cost anywhere from $350 - $450.
if u want more power then get the crower 62403 or the crower 62404. the 404's will net u over 20 whp but ur idle will be pretty rough. i think over 1000 rpm at idle. both cams require a valve spring kit which is anoth $200-$300.

Im gonna get the 402's in a month or two. gotta save up for em. (struggling college kid who spends evey dime on his car.....with no job!!!!!!)
also get some cam gears while ur putting the cams in the car to squeeze more power outta the cams.
im gonna do that as well as a full timing belt and water pump change when i install the cams.

before u get some cams, u might want to free up the flow of ur motor. get Intake, exhaust and most important headers when u install the cams! all will give u more power.

ALSO, i would get type R pistons for ur car. the pistons will really help out once u get some cams in your car.


for 500 bucks, i would go for the basic bolt on's first before thinking about getting cams. mainly get intake and headers. u can run the stock exhaust for a while

isn't the B20 the engine that comes on 3rd Gen Lude's from 89-91 Si's??? just wondering???

the b20 it actually out of a crv. or atleast the one that i got is.

oh and for the 3rd gen lude's they came with the h22.

aight thanks guys, sounds like a good idea. Hopefully with all these bolt ons the new pistons and the cam profile Ill be pushing almost 200hp with no turbo. Ide be happy with that set up. Plus it seems cheaper then going with a turbo set up any way. My car only has 78k miles on it, so I really didnt wanna do a turbo. Plus it would voice my warrenty. Bolt ons wont though so if I do internal work and the engine blows the dumb fucks wont tell the difference. and wtf does the "Main Regd" light means?

excuse me I meant to type "voide" and "maint Regd"

why do you have the head of a b20? I'm thinking put a b20 block on it. It'll get your compression up from 9.2 to 9.7. http://www.c-speedracing.com/howto/compcalc/compcalc.php

i know that right now im pushing 174hp and 141lbs of torque. atleast that is what the dyno said. i'm also thinking of new cams, new intake manifold, and S-AFC controller. from what i hear i should be at or around 200hp.

oh and for the 3rd gen lude's they came with the h22.


Errr, no they didn't. I'm pretty sure they came with b20a's. 4th gen had h22a and h23(a). 5th gen had h22.

2nd gen ludes came with the b20a and 3rd gen accord. then the h22a is 92-95. and the h23a is 92-01.

2nd Gen Lude's did not have B20's...

3rd Gen's did....there's 5th's gen's for the Lude

79-82

83-88

89-91

92-96

97-01

integralover how in the world r u pushing 174 HP? i hope that isnt wheel HP cuz i doubt u will get that much with just I/H/E cat and a chip?
thats flywheel HP u r measuing right, cuz i dont know how u r make n that much power. if it's whp then u have a freak motor or the place where u got ur car dynoed had a dynometer that was off a bit.

and to get to the 200 whp mark for ur b20, ur gonna need to get more than cams and intake manifold.
I would go with some race cams like crower 404's with valve springs, cam gears, higher compression pistons(some type R pistons will be sweet), headwork (port and polish), bigger throttle body (BBk 70mm), skunk2 IM and u might wanna upgrade ur ignition but it probably isnt necssary. this is the settup im gonna go with minus the crower 404. im gonna get the crower 403's

BTW, how is that ACT flywheel/clutch combo work n for u. is it the 12 lb flywheel? Later donw the road im gonna get that flywheel but not too sure what clutch to get yet.


and the "maint regd" means maintance required. this light is supposed to come on in all integra after about 72000 miles i think. nothings wrong with ur car, it's just reminding u to get ur car checked up. to get rid of this light, u need to reset the "maint req" light. look under ur dash by the driver side. towards the right of the drivers side underdash, u will see a black box looking thing with a blue button on the front of it. push that button in to reset ur light. thats it.
and i have NO clue what u r talk n about when u say the "voide" light??????

hell dont ask me man the dealer put the B20 head on the Ls block. The other head blew I think. Either way what would be the benifit of having that little set up. I mean hell I was able to run with a 1994 Vtec prelude on the highway yesterday rolling three deep.

and either Im a damn good driver or they other driver sucked but I raped a Gsr Stock. My car only has an intake, I think a Si transmission its really short, a Stage 1 clutch. no a/c and a hole in the exhaust pipe lol. Its loud as fuck though. But really what would be a benifit of having a B20 head on a B18 block. I have NEVER heard of anyone doing this on purpose. All i know is its a B20 head from a 2001 Crv. and the horspower rating on edmunds is 150hp I believe. Any ways isnt the normal B18B1 block a higher compression the the B20? So with the more horspower from the B20 head and higher compression wouldnt I get abit more hp?

u are not gonna get more horsepower outta the b20 head. it's almost the same as the LS b18b head.

u already have an intake, go get some headers for your car then put in a set of cams if u want to get some good HP numbers.

the b20 has a lower compression then the b18. and i have a stock clutch on and the act flywheel. and yea it is the 12lb flywheel. i have to get a new clutch b/c the stock one just can't seem to handle the extra hp and torque. i am not too sure yet which clutch to get either. and yea i was dyno'd at 174 horse power. not at the wheels though. i think it said 138 whp. and im definately gong with some racing cams. toda or cower, not sure yet. hard to find some decent cams for a non-vtec. i am looking to get hopefully 160 whp. and i still want a bigger throttle body. damn, well im not too sure than about those damn ludes.

3rd gen Ludes (88-91) had b20a and b21a motors actually depending on year
My 89 Si has a b20a5
the 88-89 Si and Si 4WS have the b20a5
the 88-89 S has a carbed b20a3

90-91 2.0Si had a b20a5
90-91 Si, Si 4WS, and Si ALB (ABS equipped) had the b21a1

These are only the USDM models, there was the INX model with a front clip like the Honda Legend and various others that were JDM only releases though.
