Honduh sleeve info.
 

I stumbled across this article: http://dwolsten.tripod.com/articles/jan96a.html

It's primarily about the CRV siamesed sleeves, but there is a minor compare/contrast to regular non-siamesed sleeves, and pictures of each before the block is cast around them.

Hope tripod lets me link to this pic... if not, click here, or figure out which ------- one I'm looking at from the article:

Now, there is also a top view that is very revealing in the article, but this picture demonstrates the problem with Honduh sleeves. You notice how those ribs don't stick out any further than the topmost solid part of the flange? Meaning the sleeve is a lot less thick that it appears to be from a topside view, when installed in the block.

I'm wondering about inexpensive open deck sleeves, like the Darton units, into a D-series. They are thicker than the topmost part of the OEM sleeve to begin with. How much sleeve wall is required for a NA build? For boost (bigger bore means less combustion pressures for a given power level and less cylinder shift aka "head gasket problems")?

very good read

Re: Honduh sleeve info.
 

you interest my brain with these discoveries Jo.

Re: Honduh sleeve info.
 

Darton open deck sleeves are good for 79mm bore in a D-application, 78mm if you run the flanged sleeves.

79X94.4 = 1.85 liter D16. Hrm. Price at that point is *not* in line with what you'd get back, compared to B-series, but the sleeper factor means you could clean up at the streetraces.

Re: Honduh sleeve info.
 

My question all this time into imports, Why didn't honda ever really go with the closed deck. Money I guess

Re: Honduh sleeve info.
 

yeah but how much would you have to spend getting your hands on a 79mm d series forged piston, eek

Re: Honduh sleeve info.
 

heres a thought what about 79mm bore with d17 crank 97mm stroke =1.9l all in a d15b8 block how is that for sleeper.
Granted it would cost @3500 usd to do.

Re: Honduh sleeve info.
 

It's called F-series. You noticed Bisi making 400 hp/290 tq off gas, right?

D17 crank = 94.4mm stroke. 79X94.4 = 1.8 liter. Still...

Don Flores built an 81mm D16 for a guy - eek! Where does the headgasket find purchase to seal?

As far as the ~$3500, that's steep for what you get out of it... unless you consider the sleeper factor, and how you could recoup your money at the streetraces because no one saw the 180-200 whp D16 coming. Add 50-75 shot nitrous discreetly for maximum ass warpage.

Re: Honduh sleeve info.
 

I think the main focus on here regarding the d builds is simple. Bigger isnt better. The few d series motors that have made over 200hp that were actually run at events were Bisi and the old gude crx. One was a 1.5 and other was a 1.6 if they were tellin the truth. Headwork for the d is the key along with the cam combo.

Re: Honduh sleeve info.
 

D17 crank won't fit into the D15 block, piston skirts interfere along with oil pan rail.

D15Baby8 build in progress :)

Re: Honduh sleeve info.
 

Like, a whole lot of the skirt, or a little inconsequential bit you can trim off?

Re: Honduh sleeve info.
 

jep, headwork, compression, and the juicy juicy race gas. can d series motors handle like 16.4:1 compression? thats what we were at on your old school wedge head kz1000 motor last year with half inch lift cams and ports the size of lemons ( its amazing how far you can get the ports out on an aircooled head ;D. sucking on some 48mm lectrons from gast, with a big bore kit to take it out to 1385 cc's or somthing like that.. putting down good power. id say about 230 spinning out to 12 grand

Re: Honduh sleeve info.
 

im going to have to read it when I get home, my work comp. will not let me view tri-----.

Re: Honduh sleeve info.
 

just out of curiousity what if you destroked a bored out d16, with a d15 crank and bigger bore you would be still at 1.6 but i read somewhere that with a d15 crank the rod to stroke ratio is really optimal so it would rev faster/higher but maintane 1.6 liter displacment possibly? im an idiot w/ arithmetic but if someone else wants to do the math and see if it would work.

Re: Honduh sleeve info.
 

RS is a rich man's NA game, and for turbo cars it is a lie.

Re: Honduh sleeve info.
 

dont believe bisis bull ---- his motors were never destroked

mike the old man at rs was a stroke king


everything he built there for b series left with 95mm cranks why would the main guy get a piece of ---- baby crank


bisi's d motors were large very large d series

oh and rs is bull ----. If your buildin a car for speed/power get a crank that fits in the block all motor of course

Re: Honduh sleeve info.
 

wow, i guess i heard wrong.

Re: Honduh sleeve info.
 

Sorry Chris, 80mm detroked D15.......78mm sleeves which helps the head flow.......

Re: Honduh sleeve info.
 

speakin of sleeves, wouldn't it be nice if honda produced a nice wet sleeve engine? that way you could do your own work? just like the heavy duty diesel market, blow a sleeve, go and pick one up that is already honed and ready to install, don't even need to yank the engine out, hydraulic sleeve puller yanks the sleeve out, then re install, and boom your ready to go

Re: Honduh sleeve info.
 

If they sold for diesel prices, ah, go fist yourself? :(

Re: Honduh sleeve info.
 

Dude it says that they have forged internals from the factory!! I'm buying a 91 prelude and swapping one into it!

Re: Honduh sleeve info.
 

Yes, they have forged internals, just like every other B-series. They also have -----in-the-ass siamesed sleeves.

Have you read this thread, or are you just ------- with me? >:(

I am going to sodomize your mother.

Re: Honduh sleeve info.
 

Shes old and in a retirement community. She could use the attention. Hers lonely

Re: Honduh sleeve info.
 

Lol that's almost as bad as the rice-boy who told me he was taking his prelude b20 and making a b20/vtec out of it. :P I guess the siamesed sleeves are ok for all-motor type of builds, but it's gonna suck if you have to have it over-bored due to scored cylinder walls. By the looks of it they're pretty much a throw-away block :(

Re: Honduh sleeve info.
 

Never noticed this article before, great info proving this is not a strong block.

I wonder what other parts they shaved weight off of to make it lighter than the LS.

Re: Honduh sleeve info.
 

so what is the higher c/r b20 good up to in h.p. on a stock bottom end ??? are the sleeve's really the breaking point on b20's or is it the rods to go ?? .. i dunno i've only hurt sleeve's from spinning rod bearings and shot a rod through the block ;D

Re: Honduh sleeve info.
 

Some people get 300-350 whp with good reliability, I think those are piston/rod engines.

I've yet to break a Honda rod, it is always the ring lands that fold. I've only seen a small handful of sleeve problems over the last decade.

Re: Honduh sleeve info.
 

My old boss laid down 410 whp or somewhere in that range on a stock b20b bottom end with alot of boost a standard super 60. Car ran low 10's this was about 7-8 years ago.



Stock 100 percent bottom end. Tuned by Harv's aka the og honda tuner so that has alot to do with it. Motor broke with a 50 shot.

Re: Honduh sleeve info.
 

i want him to tune my car :D

Re: Honduh sleeve info.
 

WEll he's in la. Harv's dyno he was on american hot rod a bunch tuning their cars

hmmm. nice thread. something to look into.

thats true

my head just got a lil bit bigger thanks bro.

its honda motor corp for a reason, i love the natural strength in honda motors.
