92 CIVIC HATCH VX

I will have the graph up soon as i get it scanned.

h22 in a civic eg

166.45 whp- 124.19 TQlbs

mods
Fake - j"s racing
Prospeed header
Apexi- exaust no cat
AEM EMS

hitting 150 on 3 first dyno's

then we figured the butterfly valve was staying closed due to the AEM not being able to control. fixed that with a screw and that's what it laid down.

compression is 155- across that's why i think it laid shitty numbers

looking for intake manifold
<skunk 2> i heard it won't fit in the EG
looking at JG engine dynamics intake manifold?
should hit over 170's with that.

after june 21st doing engine rebuild?

NXLude

On a stock usdm motor your compression should be 210 if im correct

Combustion Contraption

Wow.

Looks like most of your compression is ending up in your oilpan.

skunked

screw the manifold you need to fix that motor first.

I did just shy of 190whp on my H22 with

-Intake
-2.5" exhaust
-An-R header
-Uberdata

Yours seems really low, definetley because of the compression.

yeah i know i need to figure out how to fix with out costing a arm and a leg.

Combustion Contraption

Costing an arm and a leg? Hardly.

When you do the compression test (if you dont have a leakdown tester) pour a teaspoon of oil in the cylinder then test. If your compression shoots way up, your rings are shot. If it stays the same, its something in your valvetrain.

If its your rings, spend around $300 for OEM pistons and rings, get the walls rehoned and drop em in. Its under a $500 job if you do it yourself.

ok i will do that tonight and i will let you know the result.

92hybridAccord

hmm, my jdm is about 125 accross, but feels alot stronger than 155 whp.

I will be doing a dyno in about 2 weeks, so we'll see what happens as far as my numbers are concerned

just for comparison, my bone stock (well, intake, exhaust, no PS or AC but stock other than that) USDM H22A4 pulled 169 whp with ~220PSI across all four cylinders. I cranked the motor three times per cylinder on the comp test so those numbers might be a little high. I would think you guys need to check your piston rings. that would be my primary suspect.

I checked mine last night, 230 across on JDM H22A

canis

dude is that a little hi or am i just seeing things, what are the JDM H22 sappose to be running anyways???

Combustion Contraption

Every compression tester is different. Altitude, Engine temp, throttle opening, fuel in the system, and cam selection all play a part in compression test readings.

92 CIVIC HATCH VX

I will check when i get back from running.

if it's the rings. can i use type-s pistons and rings? i'm going all motor till september, then turbo.

if the the sides of the walls are not scared i won't need to hone right?

I will need your guys help doing this one step at a time.

tonight i will check with oil tonight.

i have never done a piston swap but this is my 3rd car i own so it can sit, i feel if i take my time i can get it done one step at a time.

keep posting guy thanks for all the help.

brandond

that motor needs some TLC before anything.....Rotieatter made like 191 on h/i/e and uberdata .....check your compression and your oil pan for metal!

Be careful on the hone job. H22 blocks have FRM lined cylinder walls, you don't want to take too much off.

But since you're in there, might as well invest in some Type S pistons and a4 rods.

92 CIVIC HATCH VX

yeah my compression jumped to 185 after i put a cap full of oil in so the rings are toasted....

i unhooked battery and unpluged altenator and took valve cover off?

i 'm looking for the head bolts? i will pick up a 94 prelude chilton and order a helms this week.

next i'm

1. draining oil
2. draining radiator fluid
3 removing radiator and cleaning the crap out of it the guy before me drove out on dirt roads and there is dirt caked in it.
4. taking exaust off
5 droping oil pan.
6 taking altenator belt off and timing belt off.


that should be part of my week before the weekend.

Part i'm buying so far.
1. type-s pistons& &lt;stock rings&gt; i guess
i will not know if i need to hone until i get the pistons out and look at the wall for scaring
2. fluids
a. Amsoil 10w-30
b. perstone 50/50 with redline water wetter.
3.timing belt
4. alenator belt
5.water pump
6.h23 manual tenstioner coversion is what i heard to also do?
7.Cam Gears &lt;AEM&gt;

should i take pics for you guys?

If this turns out big please let me know how to fix and i will.

Also suggestions

Someone said A4 rods? what are those?

A1

A4 RODS CAME OFF A 97-00 PRELUDE.U NEED THEM IF UR GOING TO USE TYPE_S PISTON.

92 CIVIC HATCH VX

can i get some after market rods instead?

why would you want to?

rods aren't really a weak point on H22s, from what I've seen

hybridpatient95

jdm h22 rod hydrolocked

it had 130psi in that cylinder lol also when we took it out the rod was bent so bad it was hitting the cylinder wall causing coolant to get into the oilpan.. so be careful guys! good luck

92 CIVIC HATCH VX

draining oil today


hey can i just install pistons from the bottom?

will save money on a headgasket if i can..

so with the type-s pistons will in need new rods?

becasue if i do i'm just going to get stroger aftermarket one's.

hybridpatient95

no you cant install pistons from the bottom it isnt happening..

92 CIVIC HATCH VX

so will the type-s pistons fit on stock rods?

hybridpatient95

on stock a4 rods they'll fit..
