about to do the b20 swap should i go with the b20 b or b20z if i plan on going turbo???

DC4 Dave

Doesn't really matter, you'll be replacing the pistons with forged material in either case, if you plan on boosting hard.

what are you guys with all stock b20s turbos reving to ??

daluv

You put a b18 non-vtec head on a b20 block? I was told this couldnt happen and I wouldnt benifit from it even if it could happen. I was thinking of putting a b18b1 head on my b20b block. What did you do to make it work, and did you see any big differences after swapping the heads?

EFinawesomeman

im doing a b20 build up here soon on my drag EF. What radiator and fuel setups are you guys running too? Keep this thread ALIIIIIIVE

In almost every case, B20 heads are near identical to LS heads.

I actually have a ported B18A1 head from a '93 GS on my B20B, and it involved no modification whatsoever to install.

Makes me wonder. Ive been through a bunch of the threads about guys cracking sleeves on 10psi or less. Ive got an ls/vtec in the car right now that has gottem me down the track in 12.1 @118. but the bottom end is not so good since my wideband went away and i tuned it lean. so ive got a perfectly good b20b that im tryin to sell right now that i got out of a customers car and im contemplating dropping that in. and im also pickin up a full 97 crv drivetrain for $400 that only has 73k on it. Im a little torn on what to do, lol.

the only thing for the head swap to work is you have to use the b20 head gasket cuz the b18 head gasket is 2mm too small but the cams,valves,springs,and retaners too. and theres no gains from swaping the heads but swaping the intake manifold will help. but for you turbo guys what are you reving too

that what i have on my car and i did not do anything to the head to make it fit. it just fits. b18b head on a b20

daluv

Any nice, noticible gains?

isaacson06

no theres no gains with the b18 heads cuz there the same but if you swap the intake manifold from the b20 one to the b18 you will see a differnts cuz the b20 flows like **** and the b18 onne will flow hella better


(what are you boosted b20s reving to ???)

daluv

The b20 IM is the tall *** ugly looking one right? I have a short one on mine (looks like an LS IM)

isaacson06

ya its goofy as hell what are u reving yours too????

italianchooch88

what ecu do you use when u do this swap?? can u use the stock ls ecu

slotec

there is 2 different b20b intake manifolds the american one is tall and ugly and the jdm one is smaller similar to a b18

my head is compleatly built, we only reved it to 9500k on the dyno and power was still good. i have not tried a b20 head, but i have a pr8 head in the works , jdm b20 head.

daluv

Mine isnt boosted yet, Im shifting around 6000rpms. Ive got an LS ecu, so Id imagine my redline is 6800, ive never put her past 6200.

Is there a number stamped on the manifolds that I could look for to tell which one I have? I know the motor came from japan, but I think my friend put an LS IM on there before I bought his set-up, but I cant remember, that was quite a while ago.

LS ECU works fine for me.

got any dyno graphs?

a1320honda

so right now ive got a turbo ls/vtec setup thats ok. but i just basicaly got a b20b that has the P8R head on it. so now im contemplating pulling the ls/vtec setup and putting the b20 in and runnin it on 10-11 psi of boost. does anyone have any info on the P8R head with boost?

DC4 Dave

No idea.

For the numerous amounts of rev-limit posts ...

I rev mine daily [all-motor, mind you] to 7400. I'd imagine no higher than that would be safe. That's, at least, where my rev-limit will stay once I get the B16 head on, until I snag a crank girdle, ACL bearings, and ARP hardware down low.

slotec

thats exactly how people crack sleeves and run into problems, they get valve train and rev to 10k or just rev the hell out the motor with a stock bottom end. The bottom end cant take that kind of abuse stock with all that vibration. Im completely stock revving to 6800-7000.

isaacson06

to put the arp rod bolts in is there a way to do it with the motor in the car and not pulling the head or do you have to rip it all apart???
