Everyone already knows the stock sleeves are thin, and the piston ringlands are weak. It is also common knowledge to "reliably" boost an H22 you need to build the motor. (Sleeves, pistons, rods etc ) Which we are going to do

But out of curiosity, is there anyone on here or anywhere who has boosted over 10 psi on a stock H22 and done it succesfully?

(Stock meaning never been apart: stock rods, stock pistons, stock compression, stock bearings, stock head gasket, stock studs, stock head etc.)

I don't want to hear the stories of people who have blown up their H22 with only 7 psi, those people don't know what they're doing.

I want to hear from people who have been successful at boosting their H22 over 10 psi


I actually rode in my boys 97 prelude (a couple of years ago) that had a JRSC. We put an upgraded pulley on his charger that caused the boost to spike to 11psi.

He drove it a couple of times with the pulley, and we could hear it starting to detonate right before the belt started slipping.

Since the belt would slip with the upgraded pulley he decided to put the original pulley back on.

Anyways, the funny thing is his Lude is still boosting on the road today and has never blown up.

 

My h23 was boostin for about 2 months. It was tuned with hondata 3b for 10psi. Ringlands blew.

 

Our secret is we boost between 9- 10 psi only at the track & 7-8 psi for daily driving, for almost over a year now

Oh, that's a secret? I've never heard of anyone else turning it up for the track and down for the streets.....

I think there's a few on here, just gotta get them outta the woodwork.

 

I'm pretty sure there is a 4th gen on here named Firedrake that runs 11psi and ran a 12.7 on slicks. I also remember someone with a red 5th gen posting about running 11psi and ran a 12.9 on slicks. I plan on running 9psi once the track here opens again.

 

me and another prelude buddy ran 10psi, ran the vafc hack....

 

I ran 13psi daily...... then it blew the F up.... not the ringlands thou, blew out the front seals........ as everyone already knows in my case

 

ive been boost spiking for about 7 months to .70-.82 bar. f-max kit without the two extra injector and afc hack.

 

thanks everyone for the replies

It would have blown up if, as I assume, he was running the upgrade pulley with the stock JR management components.

Although it is in your sig, you neglected to mention that your H22 is a JDM motor. Higher compression than USDM (10.6:1), which makes things a bit different.

 

I don't know, people always tell me that the high compression on the JDM engine doesn't matter. Personally, I thought that it did, but people always tell me that the USDM engine is just as good.

 

It matters when it comes down to boost and tuning.

 

I thought so too...it's just that some people were telling me that their USDM engine was just as good as my JDM one...when really, the JDM one has a couple small differences that make it better...IMO.

 

"Has anyone ever boosted over 10 psi on stock H22 successfully??"

Define "successfully." I 'spose I could boost a stock engine to 20psi "successfully." It's for how long that matters!

 

good point

 

good point

let me rephrase the question... how long has anyone boosted over 10 psi on a bone stock H22 until it finally broke??

 

anybody else?

Unfortunately even asking this way won't help. If someone is boosting 16psi, but drives their car only once a year, it'll last a "long time." And if you ask how many miles have people driven boosted cars, what if they run at partial boost all the time... There is no plain and simple answer to your question because it all depends how it's used.

TBL is using a JDM engine aswell. The USDMS have a touch less compression that would leave a little more room for boost?

 

I think that you would get a better responce over at Preludeonline.com There is a pretty big # of boosted ludes over there.

 

good point,I guess we'll have to find out with our motor

 

I'm dying to know where your friend got the "Upgraded" pulley. Who makes it?

 

Quoted from PO.com....

"my motor is indestrutible
no j/k

i have put my motor to the test and have put nearly 9500 miles on it at 10 psi and it hasnt blown up and i have perfect compression checks not to mention 8500 of those miles i was at a near 14.7:1 af ratio unknown to my knowledge but now fixed

i am just trying to let others know that turbo ludes can be successful on a stock bottom end dont be sceared

dont get me wrong FI can be a headache, and not for someone that doesnt like to get their hands dirty. But with the right safety equipment and a keen eye your engine can last

heres my setup:

stock bottom end h22a4
cometic .057 hp HG
skunk 2 cam gears
turbonetics t3.63 AR stage 3 wheel / t04e 54 trim .50 AR
drag gen 4 manifold
custom catless 2.5 dp
mugen 60 mm catback
hondata s200b with 3 step rev limiter w/ p72 ECU
DSM 450s
action 2KS clutch
fidanza flywheel
greddy oil catch can
modified JR oil cooler
drag gen 2 IC and piping
AVCR boost controller
greddy EGT and Boost guages
J&S safeguard classic
bkr7e plugs
stock OEM honda ignition system NEW
custom CAI for turbo inlet

i could go on forever but you get the idea


notice all the safety components and i have a conservative tune making 237 hp and 175 tq

my motor is not really indestructable"

He's runnin w/ the timing backed off a bit, so his #'s are low. I believe he said the 237 is from 7psi.

 

I boosted 16 lbs. plus a 75 wet shot on a bone stock usdm h22 w/just a 2mm headgasket. It was a t3/t4 with a 440cc, fmu, afc set-up running off a stock p28 ecu. The car was a civic cx with no back seats and went 10.90's at 130-133 in the 1/4 and 7.0's at 102-104 in the eigth. Lasted 6 months like this w/no problems and then took the set-up apart to build it and its been sitting ever since.
