How much psi can stock sleeves take?

[swooshek]

Hi im curently running a 7psi on a b18c, and am wondering how
much pressure say a stock block, forged pistons, forged rods
and crank could take, the sleeves being the weakest link.

I know allot comes down to tuning, and compression. Im thinking if it's
worth commiting to a sleeved block or not, i've heard those wild rumors
of sleeves taking from 300hp - 400hp.

Rumors are true. But you've gota ask yourself. Your spending all this money elsewhere 'strengthening', why skimp and be limited with stock sleaves? Do it and you'll never regret not doing it.

[OMG.JAI xD]

^^ 2nd that.
Do it right the first time so you dont have to do it a second time.

People claim all these powers with stock sleeves. Well their aim wasnt power. It was to prove the strength of stock sleeves.
If u want reliability with power. Then strengthen what ever you can.

18-20psi on stock sleeves

B-series Block (b16a & b18c) have pretty strong sleeves

Sleeves cost a fair bit these days, IMO you dont need sleeves unless you want well over the 600-700hp mark

How many K's on the motor? Sleeves will be a good investment but depends hwo much dosh you have to play with. If youre going to keep the car and thrash it - put in the sleeves.

how many b series motors are making 600-700hp??

[Q_ball]

My stock b18b sleeves were able to withstand 15psi, 213kw atw

EXQZIT for one :p..

ill be pushing mine to 20psi in a couple weeks so i can tell you then.

You guys have no idea you spend too much time in the forum, for 1 MISTCHF CRX split his sleeves i split my sleeves Massive crack, its not boost unless your boosting 30psi and above it could be tuning and and how you drive Note: If your on revlimiter for half an hour before shifting will aventually do it, thats what happened to mine 21psi, injecters maxed out rushed tune, was on limiter at track maybe didnt get fuel and detonated, but this had 5years of punishment. Honda motors are unbeleivable your bs, ks and the SR20 has that status the Japs are doing well:honda:

Im a little confused as to what your getting at with this? your not boosting unless your boosting 30psi and above? lol

[Limbo]

i got some, sleeves don't last above 21PSI?

[Riced_Civic]

my D series sleves last up to 500hp so i think a B should be ok on a mild set-up.

if built may as well do it since its open

[redL9]

you wouldnt waste your money unless your chasing huge numbers Darton sleeves are deere, what im saying there are allot of fundementals that can happen or cause a split sleeve, its not boost in most cases. Riced Civic love to see your dyno sheet? My setup wasnt mild either no cost spared.

I found that 280kw on semi slicks babing the car off the line and spining half track for 12s...@120mph What for you know couldnt afford the slicksThe more power you put through a FWD on semi slicks wont get you a lower time these cars with big power need slicks, do you guys agree

[VTECnique]

I have to agree with redL9, its not how much boost you run that cracks/destroys sleeves, its plenty of factors, tuning, fuel, ignition, they all play a key role in a healthy motor.

I know there are plenty of Dseries guys overseas, running more than 450+whp on stock sleeves, but how long the sleeves will last is another thing. Making that much power, you've got a helluva lot of cylinder pressure the stock sleeves has to take. but with the right tune, fuel components, timing, etc. you could run 30+psi for a long time. Lets not forget, those cars making that big of power either only use the car for drag/dyno, or if they daily drive, turn the boost down to prolong the motor. For a street car/daily driver, i wouldnt boost passed 20psi, unless you own or have shares in a tyre company!!

[redL9]

spot on, you hit the mark couldnt say it any better.

[Lukezen27]

Man I need slicks on only on 8 PSI hahah

[Benson]

Stock honda sleeves are hell strong. Just need to change rods and pistons and you can wind the boost up to 20-25psi. Wack in E85 and get a REAL GOOD TUNER and you'll have a crazy boosted package.

tru that man....10psi atm and my 235's are pointless.

Im not gonna run it upto 20+ psi for a while...

happy with it atm, gonna buy a new map sensor and few other things and when i bored ill boost the crapp out of it.

[lookingforboost]

hmmm to finish the D or buy a B thats is the question for me atm ...... :?

15psi will be safe.

Dude, keep the bloody D...

stock b16a sleeves are fine providing your engine tune is correct.
i ran stock sleeves at up to 36psi @ 10,750rpm in my engine, i have never hurt a sleeve..... cold intake temps,low exhaust temps and back pressure, a good ecu (motec),good fuel and a tuner who knows what he is doing will never split a sleeve ( unless the engine gets a dose of dud fuel or runs very warm when its under boost)

[redL9]

Illya, who tuned your Honda? Do you have any drivetrain components left for sale, injecters or ecu still up for sale?

I tuned my engine... along with my old boss looking over my shoulder.
i have my complete engine combo left- everything else is gone

sounds like a plan :P
