For those that dont know, about a year ago I oil starved my original 5th gen H22a4 motor, which i then replaced with a JDM H22a with ~45kmiles.

Motor is bone stock, stock cat, stock exhaust,stock everything.
Only modification left in this car is the competition stage 4 clutch & flywheel I ran on my boosted setup.

I was Hoping for 180whp but ended up almost hitting 190whp. I was at 184whp when the tuner offered me a short ram intake w/ filter for a steal so we added that to get to 187.

So single mod is a short ram intake:
(Tuned with crome by HPC in ft lauderdale)
Base line was a very basic tune phearable.net supplied me with the chipped P28 back when i purchased it.
Needless to say I'm very impressed with this motors stock numbers, the tuner couldnt believe it as I was outpowering h22s with full bolt-on's that he dynoed the previous month. Missed that stock pull even coming from boost...

Very good numbers...So this is basically a stock JDM motor that was tuned??

yea wednesday motors rock!

ragethemachine86

yes it's a bone stock h22a out of a 4th gen i believe. Short ram intake, stock header, stock cat, stock exhaust. Claimed to have around 40-45k miles on it. After putting my car back to stock from boost i was gonna keep it stock but I'm intrigued how much i can make with a good header and more free flowing exhaust setup... 210whp dd would be fun

AznBlueBoy

maybe its a type s motor?

bb6envy

it must have type s cams and valvetrain. I have a jdm h22 type s with an apexi N1 exhaust and crappy dc headers and a crome tune done by john earl at BRE motorsports and dynoed 197whp.

crxsleeper210

Wow that is very interesting...Nice gains especially for a stock motor.......When i get my "fresh" jdm h22 this summer ill be adding a header (hopefully not a cheap one) CAI and exhaust and plan on tuning it and leaving it like that for a while....

Vipers4Life

Did you buy it online or from a junkyard? Very good numbers for a stock H22a. Be ready to spend massive money on a good header lol. I highly doubt you will see 210whp with a header and exhaust lol.

A 23hp gain from header and exhaust? Probably not going to happen, but you CAN get close.

minilogoguy18

He probably doesn't have the Type S cams, they don't even add much anyway, its a lot more than just the cams that give that motor its extra 20 hp. You're headers don't add any power and the exhaust is questionable too since even though its larger in diameter that system adds an extra bend just to look cool. All dynos read different too.

ragethemachine86

very true guys it could very well be a type s... any way to tell for sure? and it's not out of the question that it was modified even if it was imported from japan. and the 210whp was more of a hypothetical statement, meaning that would be a great number to reach. I am by no means getting into another project car since i just got off boost and need to focus on my studies instead of work.

Ill try to save up some money for a good header (maybe here thru the sponsored marketplace section, saw some custom ones go for ~500). And as far as exhausts go I want something subtle anyways so 210 at the wheels most likely won't be reached...

0Mike95lude

That is great power if you are really running it through the stock exhaust. Do you have the SAE Corrected numbers?

mattsnooz

Those numbers are somewhat similar to my 4th gen jdm h22 tuned on crome. I have I/H/E with butterfly plate installed and IABS operating and hit 201 whp

They are wicked motors, I'm very impressed. Especially with the CAI. The sound vtec makes when it engages is lovely.

On that note, I have IABS engageing at same rpm as vtec. Has anybody found a better point to engage IABS?

ragethemachine86

now that i think about it, i moved over my usdm intake manifold (not sure if it's any different) to the jdm motor. This IM still had the dual blacktrax intake manifold spacers which replaces the IAB's. could this explain the increase in power?? The tuner claims no saying it could have only hurt my low-end...

vinuneuro

Those spacers have been shown to loser power.

mattsnooz

I believe IABs do hurt low - end a touch which is why that extra runner engages only at higher RPM, but mid range to upper there was a 5-7 hp increase with appropriate tuning on my graph, with the stock Single Plate IAB. I think having control of the IABS is more usefull than just having the spacers.

The type S motor should have a red valve cover. The Type-S is just a Type-SH H22 block and head. The Type S pistons are domed giving it a CR of 11:1. The head has a mild port and polish by Honda, with a better intake tract, a slightly larger throttle body,a different IM, more aggressive cams, upgraded valvetrain, and a better header/exhaust system.

WavyIntegra

Doesn't the JDMh22a SiR motor have red valve cover to? What about the trans connected to it, are the Type S trans LSD or is it possible to get a Type S without it?

This has me very curious at the moment...

Vipers4Life

No, I am pretty sure the SiR motor has a blue valve cover. The type s motor from hmotors comes with the honda LSD trans, not sure if it can be optional for a lower price..but you could ask them. I'm sure the type s will work just fine with the regular trans.

WavyIntegra

I'm feeling like an ******* right now.


I brought a JDMh22a motor..Red Valve Cover, but from what I saw I couldn't tell if it was LSD Tran'sed or not...

My goal was JUST for 200whp, nothing more because I knew going higher meant spending more money, If I could have gotten that with JUST a Hondata and a Type S motor with MILD upgrades, The near thousand dollars and change I'm spending on valvetrain and tuning could have went elsewhere...

Feeling real dumb right now. I wanna take it back apart and put my stock parts back in and send these Cams back, i'll keep the dual valve springs but I can put that cam money somewhere else.

Vipers4Life

See if you can find the code on the trans and then look it up online to see which trans it is. How much did you spend on the jdm motor?

WavyIntegra

Well I got the entire Car for practically nothing, from a guy who used to frequent these boards and lives around me. He brought me the car and asked for me to rebuild it with components that he had bought..he was going for a high compression build.

From my understanding he was recently incarcerated, Ran from the cops, long winded chase, epic **** but ultimately he wound up caught and I got word from his friend that I could do whatever with the car.

So I'm like.....ummmm...ok? I had already done my DA up, Full build, high compression pistons, skunk2 valvetrain, ect, ect. I've been a mechanic for years, but im an enthusiast for roughly a year, so I don't know how to differentiate motors..

I KNEW it was an h22 on sight because well..it' was BIG AS ALL HELL sitting snuggly in an EG Coupe, Red Top VTEC Valve Cover, engine code H22a and a buddy of mine confirmed it was a JDM motor, only thing he couldn't tell me was whether it was a JDM Sir or a TYPE S..

As I read now, SIR has a black top..and the Type S has a red top. SO I got the entire car and swap for free..but i've already poured about...$1600 into the car which doesn't include the Mahle 12.5:1 pistons I sent BACK.

I ONLY want 200whp..I feel 200whp in a Daily Driver is sufficient, I don't race (I used to Autocross and drag when I was a teen, i'm alot older now so I'm not into it anymore) but I just want something thats gonna pull and tuck *** whenever I decide to wanna move fast and do it with a PULL I can feel.

I'll get the tranny code in a moment and let u know...but if this is a type s motor and I think it is, i'm pulling my Skunk2' Cams back out, leaving the Dual Valve Springs and Valves in there and sending the cams back, use that money for something else.

Kronn 98SH

That's completely wrong.

NirVTEC

High reading dyno. /done
Stock H22s on the dyno where I made 204whp were making >160whp.

Vipers4Life

What's "completely wrong"? Would you like to see the link to the type s motor with the trans? Don't just tell someone they are completely wrong and not explain what.
