Hey i am trying to decide whether to swap a b20 with b16 head into my 89 honda crx, but people are telling me that i can get more power out of just a b16 engine

 

A B20 with a B16 head (done properly) will crush a stock B16 hands down. Maybe if you build the hell outta the B16 and spin it to the moon you'll make more power but thats about the only way..

this was my stock 20 bottom end and b16b head,

i would love to see a b16a do this to a tuned s2k

 

Lol. I used b16 blocks to make a coffee table

 

b16 with a racing skunk camshaft.maybe a stage three clutch and youll be rippin.
just a 16 or a 20?????????it'll be good on gas

 

i wouldnt run anythin over a typeR cam on stock valve reliefs, maybe buddyclub spec3+

 

you kept up with a s2k? good job. beating it would be worth talking about.

a b20 block with b16 head would kill a b16a all day. unless you bored it out in which you'd just have a 1.9.

 

Actually a b16 bored to b20s 84mm only equals a 1.7 because of stroke.

the b20 should rip a b16 all day with similar money in them. the only thing a b16 is better for is rpms or if youre trying to stay within a specific lower power, like me. im building a b16 for my local time attack where we class by power to weight ratio. also the track has half the track that being able to stay in gear and pull higher rpms means no time lost shifting, where with a b20 id have to shift up then 1-2secs later shift back down.

 

The only way the B16 would make more power is if it was turboed, and the B20/V was naturally aspirated. If you wanna stay naturally aspirated, the B20 block B16 head combo would be the way to go.

 

THanks guys , i heard that alot of b20 with b16 head have failures, but i know itscheaper then buyng a b16

 

oh and what tranny should i get for b20 with b16 head

 

what video were you looking at? O_o

clearly past it at the end

s2k was in first gear btw :D

 

if your staying stock i recommend changing rod bolts to arps..

i had a 98spec itr box with a KAAZ 1.5way was serious, also an itr flywheel is a good upgrade.

although i dunno how freely available those parts are to you guys in the US

 

the b16 tranny. with an ls final drive and maybe 5th. LSD.

 

For NA, I'm running a GSR tranny.. Best of both worlds, unless your budget can call for an ITR or CTR...

 

Is that the lower compression b20 or higher one in that video against the s2000?
