for all intensive purposes, what's different about the heads?

the intake manifold is something separate all together.

and they can't take the rpms... and require machining and new pistons to become vtec

why can't you boost a b20... and just set the rev limiter to like 6000 or something??

You CAN boost a b20, it is just unwise..
the cylinder walls are a tad on the thin side for boosting.

as for the head, theres no real difference, and VTEC doesn't really have anything to do with the pistons.

depends on the sleeves, if you're looking to boost a b20, you're better off starting with a b18b have it bored out, and sleeved to 2.0. and that will be your displacement.

check leitner performance

how well do you think the b20 would take to nitrous, with a nice set of pistons

B20B head

Guys, fact:
The HEAD on the B20 that I've seen is stamped P75 just like my B18B1. So they probably are the same.

Did Bbbbbarbulo get proved wrong for the first time, up above there! Oh my God!





Just teasing.

i thought the pistons in a b20 do not have valve reliefs cut into them... so there wouldn't be enough clearance for the valves on a vtec head??

Yes that is true 100%

but to answer the question, the actual function of the VTEC is performed in the head. Where intake and exhaust valves change profile, (the opening of the valves nice and wide during high rpm) and not a function of the piston.

OK, after sifting through thispost, I have decided to post. There are a few misconceptions here. The B18B and the B20 use the same head, rods, valves, springs, and the like. As far as boosting a B20, the R/s ratio isn't that great for boost, as the high RPM's will cause piston slap, and that's the sleeve problem. The sleeve walls are definately thinner than they should've been.

Now as far as driving a B20. I have a B20 in my 93 Coupe, and who ever said you shouldn't put one in a coupe shoud not really go around saying things like this. It's just not true.

Who ever said that a B20 in stock form has the best low end pull also should try not to pass bad information along. Have you ever driven a Prelude powered Civic?

ASide from this, to the original poster thinking of putting a B20 in their car. I have put over 10 000 km's on mine with no problems driving the crap out of it. I have a JDM B20B with a B16 LSD tranny in my 1993 Civic Coupe Si. my only gripe with it, is as everyone has said it DIES in the top end. I will either installa VTEC head or, resleeve the block and put a Turbo on it, at some point in the future, but for right now it's great and I love it.

Low end pull RULES!!

Thanks for the first hand info Clayton...I think I have decided to go with a B20 platform, and have it resleeved before anything, then a vtec head...I think It would be a killer combination... As far as the H22, it sounds like a great Idea as you say it will pull harder than a B20, but IMO the H22 is abit heavy for a civic and Im afraid of it making bad handeling charecteristics, plus it seems to be a crowded engine bay...no power steering, and expensive mount conversion...

How much did you pay for your B20? And was there any major conversion issues, like ecu problems?

Where? What did I miss? I barely said anything in here, I'm just sitting back enjoying the discussion, and how JSK is schooling everyone in the ways of the 2 point oh.

I think is refering to my post where I wrote:

Geez, work with me people!
Its the spirit of the post that is the issue. The question of whether or not the B20 is or

I don't think I was passing on bad information,
If you what to be **** why not say something like a K24 powered EP, or a 3.2L hybrid hack powered civic...

for the more decerning people here that will jump on my back allow me to rephrase!

For B-Series Honda, nothing can touch the B20 down low

To reinforce the point that Clayton added to:

the B20 is JookSingKid Approved

Maybe you should've read the posts twice or even the title of the thread first - people aren't that stupid here to say that a B20's power can kick any Honda engine's (i.e H22) ***, we're talking about "B" series motors here and if the B20 would be a good swap for BoOsTZeX.
