I don't know if this already been addressed or not but I have a B20 with a LS head for now and I haven't been able to go to the dyno or track yet. My question is does anyone know what this settup is putting out just the way it is with hp header, aem cai, b&m fuel pressure reg., bbk intank pump, act3 clutch, 95 delsol si tranny. If anyone has any idea and any charts or anything like that to back it up I would really like to know, I'm getting ready to start building it and I would like to know what I'm starting out with. THANKS

The LS head is exactly the same as a stock B20 head as far as I know, so you aren't picking up any additional power from it. I would say whatver your stock rating is + maybe 10 crank power would give you an idea. Check out http://www.importreview.com for dynos of various setups. I think they might have one of stock or near stock B20's.

ok i checked out that site and the only #'s they had were from B20vtecs I'm looking for nonvtec stats, but thanks for the input

Is it a B20B or B20Z?
The LS cams will give you a lil better top-end.
Your prolly around 130-135 at the wheels.

i thought the ls head was only for 81mm bore and the b20 was for 84 which would make the ls head give it more compression? am i right?

Nope.
The LS and B20 share the same P75 head casting.

just wondering but .. why build a nonvtec b20 swap ? why not ditch the LS head and go for a SI head ... ?

Skip01

B20B:
98 B20B stock head and block, 94 P75/LS ecu
Intake: GSR stock cone filter and tube (no airbox), LS intake manifold, 64mm TB
Ex: GSR exhaust manifold, test pipe, Greddy BL exhaust


B20Z:
98 B20Z stock head and block, 94 P75/LS ecu
Intake: GSR stock cone filter and tube (no airbox), LS intake manifold, 64mm TB
Ex: JDM 4-1, test pipe, Greddy BL exhaust


Also this is at the wheel hp,so there factory specs should be a lot higher.

theSQad

so thats a non vtec b20 block .. compared to a vtec b20 block with gsr manifold ... hmmm ?? so are non vtecs better for all motor build ups ??

they are both non vtec, the only difference is one is a b20b (96-98 crv) and the other is a b20z (99-01 crv)

the b20z has higher compression, 9.6:1 compared to 8.8:1 I think

Anyways thanks for all the input ya'llve been very helpfull. THANKS

theSQad

cool .. thanks for clearing that up ... hmm so 99+ b20z is the way to go .. higher compression .. newer block .. thanks yall .. !
