Whats the maximum horsepower everyone might have seen on stock sleeves? I'm running a fully built LS w/ cams, rods, and pistons. Its boosted from a Holset HX35 w/ some custom mods to the Charger itself and tuned on an AEM EMS. On 12 pounds of boost w/ 640cc injectors and 93 octane pump gas I made 421HP and 370 Lb/ft. I Just got a set of 1600cc injectors and i'm debating E85. I've heard and seen E85 work wonders on a stock block but I'm wondering about a built bottom end minus sleeves. Anyone have any info on this?

Your pushing it past 400

my buddy on this forum made 421 on a stock sleeved LS, when to put a vtec head on it and found 2 mildly cracked sleeves....

I wanna push this engine and I think my weakest link is gonna be the sleeves although I don't wanna tear it down to sleeve it. I made 421 on stock sleeves too its actually spiked to 467 but it wasn't sustained because the injectors were running out so we turned it down until it could sustain a power level for the whole pull. I have a friend running an H22 with ARP headstuds as the ONLY mod and he's been running that setup for almost 2 years now

500-550 has been done on stock sleeves but at that point its kind of walking a tight rope since if something does happen it can cost you big time (head damage, rods, pistons etc.)

I made 415 my self on a completly stock gsr and I didn't have any issues. I sold the motor and it was running as of last week until his crank pulley shreaded his keyway. That's another issue in itself

i got ls stock sleeves with 9:1 pistons and blockguard made 428 on e85 at 22psi with 880cc injectors

TopEndTuner

That's another thing I should note, fully built engine but no blockguard

eagle rods/wiseco pistons
ctr cams
simple setup and it was tuned by MASE

HiProfile

Sleeving a b18b block is under $1k from Golden Eagle. Figure out how much a cracked sleeve can cost in parts: 1-4 replacement piston(s), remaching a new block, new bearings for that new block, possibly a new head if you tore up the last one with a chunk of sleeve. That's easily $500-700, and you'll have to reduce power to keep from cracking another stock sleeve. Add the time to replace/install, downtime, and and labor you can't do, and you're far better off with a sleeved block.

You can also save if you look around and find a used sleeved block for sale. I was an hour late buying a sleeved B18C5 block w/crank for only $500...

TopEndTuner

Yeah but I kinda want to see where this setup will take me. Lets be honest too anything over 600 is a bit of over kill for a FWD on the street

ahobbs

Anything over 400 is crazy on the street

TopEndTuner

But so much fun!!!

I made 585 on a stock ls/vtec and ran it for 2 years with a **** load of passes on it. I finally cracked a sleeve last year.

acrite1999

were in 2009 now, technology is a ***** fuka...we have are cars with 700hp dialed in on the street...get the right combination to do it and it will happen

LightningTeg

Your a moron

i have stock sleeve lsvtec gt4294 20psi street tune and its holding fine for the last 8 months or so.

if you want more power than your current 420ish power, just go and sleeve a block. There is no reason why you should settle for pistons and rods when you are going to for big power on a stock sleeves... People sleeve their blocks because they want to do it right and have a little bit of insurance with there block. There is no reason not to sleeve your block if you have the money cause you are going to crack a sleeve in a matter of time.. I am not saying that sleeved blocks are built proof but they are ten times as strong as stock sleeve blocks for sure..

mechanix619

Yeah but not done safely in a Civic. I'd drive a 700hp Supra or something else with a better frame.

TopEndTuner

Yeah when I built this motor I wanted 401 HP but on the third pull when it spiked and made 467 I decided I wanted to try for 500. After I've been noticing what is going on with E85 I decided on going that route and by that time the engine was already built. I just cannot justify tearing down a perfectly good, and not to mention otherwise strong, engine simply to replace the sleeves. I figure if its not driven everyday it will probably hold up but I was curious about the limits people are seeing with these sleeves so that I wouldn't overshoot it and crack one on the dyno

The 417whp civic I drove would spin in 4th, with new drag radials and a full suspension (drag not auto-x). Yes you can turn the boost down to a usable level, but I've driven cars with smaller turbos that felt much faster around town, not JUST on the freeway on-ramp.

Then there's myy cousin's friends in an import club, one guy has a 1k hp Supra, another an NSX with a twin-screw blower. Neither can hook up, even at speed. I'll reiterate the earlier comment - over 400whp is pointless on the street.


If you want to spin your tires and make noise, just get a Z28 with winter tires.

well said man..
thats why i love my 300hp civic on the street

but yall are talking about stock sleeves....
i have stock shortblock;p
lol

turbociv910

512 whp on 82mm ls sleeves.. 21 psi on 35r on a fuel mix.

Meister vtec

had the exact same experience HiProfile!

+500 whp eg gsr-t vs mild boltons on a b18c-r ef guess what happened?

1-2 eg gets raped and no sign of him up untill the end of 3rd at almost 100mph and thats with 225 falkens + a very serious suspension! the only way the turbo would win right off the start is if they would start from a roll at 60.

conlusion:all that money tossed at build parts,suspension,tires,tune,clutch and the fact that all that wont even last long since all that wheel spin is going to just eat the threads on that tire and for what? I would have been ashamed if that eg was mine seeing that ef flyby.

anything above 300whp is over kill for a -2500lb feather specially since its fwd.
