Who does it? Problems so far?

 

some guy on here did that and he said they lasted 6 months then cracked.

 

That guy i heard was also pushing it on weekends pumping 18 psi and running at the track every weekend...So far 3 tuners and honda mechanic(mutual friend) have told me stock sleeves CAN handle up to 28 psi if tuned properly. And as far as 15+ psi daily if any car sleeves or not, and gets ragged on nasty every day something is bound to f-up no matter what the engine has.

can you say "DAYM"? thats alot of psi for some stock sleeves...

 

It suck, I want to get my block sleeved before I rebuild it, but I can't be without my car for so long, its my only ride.

 

I ran 16-18psi on my engine with stock sleeves for 12,000 miles. I had JE pistons and crower rods though. I ended up blowing a vacuum line to my map sensor at 16psi and running super lean and detinating really bad. I broke two of the JE pistons and put a little mark on one of the cyl walls (because of the piston breaking). But never the less the cyl walls looked clean and perfect. Im surprised they didnt break when i detinated so bad which such a high boost. Honda cyl walls are very strong if tuned correcly.

BTW 16psi was on pump gas, 18psi on race gas. 9:1 JE pistons.

liam

 

I run 15. Its only been a month at that boost level. Nothing wrong yet.

 

I run 14psi with stock sleeves but its only been about 1000 miles so i'm not the best person to give advice on reliabolity.

 

we've run 20 lbs + with headgasket and race gas. 12lbs w/headgasket and 93 octane. 15lbs w/pistons/rods/93 octane. if you tune it well, it will all work. with a standalone, you can push it even further. we know someone who pushed their stock block to 475 w/haltech. stock honda parts work.

 

That blanket theory may hold true for civics and tegs, but goes out the window for preludes. Unfortunately, sad but true.

 

wait, people modify preludes?

 

thats what I like to hear!

 

Some try

 

I run 16psi on 93 octane on stock sleeves on a LS every day over a year now, people do not understand its all in the tuning. ( key word TUNING)

 

U said it, most people find it hard to believe that others run what seems like insane power on a stock motor. Tuning, tuning, tuning!!!

 

I've been seing more people running standalone nowadays compared to a year ago!

 

Standalones offer much more precise tuning than you can ever expect to get with a piggyback or FMU setup. Not to preach that my plan is the best or anything, but in general a standalone is safer on the car and will provide more HP than other methods.

 

I ran 15 PSI on stock sleeves for a while before my piston rings gave up. The stock sleeves looked perfect!

 

15+ psi DAILY on pump gas will eventually crack your sleeves. Just a matter of time. If you are rebuilding your bottom end - might as well go and get the block sleeved.

 

I know a guy running 19psi. on his Si with stock sleeves. No problems....

 

LOL!
