Sup everyone I have a 00' prelude with the following mods
aem short ram, Hondata Intake Gasket, Hondata S200 w/ 550cc's, Jackson Racing supercharger @ 6psi, Kamikaze header, Custom 2.5'' exhaust, 2.5'' carsound cat, MSD ignition, ACT steet/strip clutch, Fidanza Flywheel, Walbro Fuel Pump, BM Oil Cooler, AEM fuel rail,filter and regulator, Fluidyne radiator.

I already bought my 9 psi pulley. I'm wondering if i get a JS Safegaurd will my engine be ok? also do you think i should get a low compression headgasket?

 

i dont know man looks a lil risky, from wat i've seen your car will be a ticking time bomb, with the 9lbs pulleys.

 

I think with good tuning and the J&S you should be fine.

 

Get the J&S and watch carefully for signs of detonation or lots of timing retard, although you'll probably notice the power loss. I wouldn't exceed 6psi on the JRSC because of the high intake air temp issue.

 

Don't do it without the J&S, and get the monitor for it as well. Have it tuned so that your a/f is below 11.5:1.

Below? You must mean above. If you're below 11.5:1 you're going towards a lean situation rather quickly. You want to stay in around 11.5:1 or above (of course not too rich)... otherwise detonation will become a reality rather than "watch for"

 

The higher the number goes the leaner the A/F ratio is. For example 13.0:1 is leaner than 12.0:1.

With your current setup you should be able to run the 9psi pulley for a while. Keeping with what Shark said, you should tune for below a 12.0:1 all the way through the rpm band, you will sacrifice some power but it will be safer. Also the J&S is a must and you might want to look into water injection, just to combat the high temps. I don't think your engine will last forever with that setup but you should be good for a year or so. Also buy yourself a Compression tester and test it every month. If you see a cyl going south you will have some time to save for a rebuild and not stress it even more.

 

it's a toss up. you could blow your rings/lands at 6psi or 9psi.

just hope tuning is optimal.

forgo the j&s. i used to run it in my h22a acord turbo. the problem with the j&s is that it sometimes picks up vibration as detonation. it also at times retards timing way too much to benefit from the pulley upgrade. still an awesome tuning tool, but it has it's flaws.

invest in a water injection kit or some sort of device to cool the air since an ic isn't possible.

 

H22a4, no good for boost.. open deck

 

says who?
easily fixed

 

Can't even run 1.5 bars

 

that's only b/c of the factory Honda MAP sensor.... another problem easily fixed

 

sorry, but the block being an open deck has nothing to do with it not holding boost.

the stock sleeves will easily handle 15psi.

all b series blocks are open deck and can handle 20psi on the stock sleeves.

i boosted for 6 straight months at close to 10psi on my 99 h22a4. no problems at all.

 

Water injection with a 5th gen lude and the JRSC is not possible at a reasonable cost. There is no room on the top side of the runners because the blower is there, and there is no room on the bottom side of the plenum to fit injectors in the runners, unless one had some custom inectors engineered and made to fit (which would cost a ridiculous amount of money). One could run one or two injectors into the adapter plate (as the JR injection setup does), but I would not recommend it because it would not give an even spray to all four cylinders, and that would just result in a dangerous situation.

I have very little problems with the J&S picking up noise. The sensitivity of the unit can be adjusted to dial out extraneous noise. The benefits of the J&S absolutely outway the minor problem of noise.

 

Below, above, semantics. We are saying the same thing, actually, so let me reiterate for clarification. I would not run leaner than 12.5:1 for 6 psi with a JRSC, nor leaner than 11.5:1 for 9 psi with a JRSC.

 

you got lucky, b-series sleeve aren't made from the FRM, and are stronger, besides that, the ringlands are what is weak on the H22 and usually fail under high boost, you my friend just got lucky to boost 10psi with it stock, more times than not, you will run into problems.... and why only for 6 months may i ask, what happened at the end of the 6 months?

 

the frm lining really has nothing to do with the strength of the sleeve. i bet the h22a could handle close to 20psi on the stock sleeve, just don't know anyone who has since you can't run forged pistons with the sleeves.

as for my close to 10psi, yeah i did get lucky. my set-up was a vafc, 10:1 fmu and paxton inline pump.

to tell you the truth i have a couple of friends that have run what i have for a few months to a year with no problems. the h22a is definitely tempermental. sometimes you get lucky sometimes you don't.

only 6 months because i got bored with the car. i had the car since new and wanted something different. have had 4 cars since but now i have my fully built boosted integra pushing roughly 500whp. t4/60-1, haltech, 2.0l, etc., etc.

 

blah blah blah.. h22 own JOO!!

 

haha jason, i'm thinking about getting another 4g vtec prelude.

we'll see though. definitely like the h22a.

 

lol you know what, i totally messed that up. You're right, and that's what I ment to say (I don't know how i got that backwards). lack of sleep maybe, who knows.. i do have periods of stupidity. Oh well, but yes, it's A/F, 12-A/1-F.
