Doing an h2b, got a killer deal on a s2 rbc mani. So i ran with it. Reading up on random crap stumbled on " the s2 k2h adaptor is not intended for use on jdm heads. Wtf ? I knew i had to trim the mani near the tstat housind, finesse the bypass a lil, but im still not close. If anyones tried this or can shed me some insight i cant find squat. Thanks.

 

The JDM H22 head is no different than a USDM H22 head.

 

Thats what i thought, but, jump on jhpusa quick and see for urself. So i guess more fabbing it is

 

How about tstat housing and/or coolant bypass tube ?

 

Personally I wouldnt go K2H for a couple reasons. First off I hear from all the K guys how much the stock intake manifold robs them of power. From what ive seen on dyno sheets from my digging is it only slightly give you more top-end power. No real benefit for power under curve. If your not boosted and staying N/a you make your power down low not up top.

Not to mention you have to buy a K series fuel rail, FPR, and k series injectors. To run H-series injectors you have to have it machined. RBC's suck so while at the shop might as well have it gutted and polished to see more gains. Not mentioning the adapter plate, and any other unseen installation requirements.

In the end Ive seen people invested way too much making their K series mani work on their H for little gains too. Maybe if you were boosted, but you want a small plenum when your N/a. Thats why the euro-r intake is as good as it is, wide runners and short small plenum.

It would be cool, and unique. But theres not a whole lot of guys running that set up for a reason. For the cost of it in the end, you could have a fully built euro-r or a strait custom intake for less.

If you do want to go K mani get the JDM RRC intake not the usdm one. Its has tiny bit bigger runners so it flows better and if your going to drop the pretty penny on doing it. Might as well get the good one right? lol

Just trying to over some honest good advice, hope you take it.

 

The only problem with this is my clearance issue. I scored the skunk2 k mani for cheap, rail, injectors, and fpr all for cheap. Grabbed the plates, so im stuck in this direction, im just trying to figure out why its suck a sob as far as fitment near the tstat housing and bypass near the housing, is all

 

See thats where your first post made no sense to me. If its a skunk2 why did you call it a "RBC" those are USDM stock oem K series manifolds?

So you own everything to do it? You need to be more descriptive then that, I still dont understand where your having clearance issues? Which H series did you buy? More then likely you have or will have a P13 head. Depends on which one you buy it may come with a PDE. I know to have the Euro-R intake manifold "originally a PDE intake" fit on a P13 head you have to grind the top of the matting flange on one side. Maybe something similar?

 

96 jdm h22a head, engine to b exact wich i had stated in my first post. Spoke to a rep from s2 personally, said the mani itself had to b cut a lil. Np. The plate however needed to b ground a shitton, fits, but the intake isnt even close, even a lot tsken off of that as well. If anyone cares to see pics im new to this but have a few to show how much ive taken off from the plate and mani.

 

My bad, meant to put "jdm h22a" apologies

 

^^^ You just said H2b, there are ALOT of different H series. Pictures would help out more then any explaining will.

You have a P13 head, 100% sure of it.

your grinding your adapter plate??? Dont they need to be so thick to allow the bolt to tighten down? Your going to end up with a tower of washers on each bolt...

For being new to this you sure chose a more difficult path lol...

I still dont see how it says not for JDM heads? The USDM P13 and JDM on are the exact same. Same goes for the PDE, with exception certain ones came with factory hand smoothing and polish. Doesn't make sense to me...

 

Im not new to the game by any means, and im grinding the side of the plate, not from its thickness. The mani has to b ground the same. Issue im having now is the bypass tube prohibits the tstat housing from bolting up. Like its not close at all. Dont wannt dent the bypass if i dont have to, and the bottom right bolt on the manny hits the bypass tube as well. New to honda-tech is what i meant. Dont kno how to upload pics

 

You upload to photobucket.com, and paste the IMG code.

 

This is before and after. The plate itself will bolt up. The manifolds the culprit

 

Sry, this is the b4

 

Ok, guess my phones wants to b gay now, so thats where im at now

 

sad to see good parts hacked up lol, now you cant resell the S2 manifold later down the road for whats its worth. Show a pic of it trying to be matted to the head, so I can see why your hacking away at it. All the euro-r needed was the flange above the two ports closest to the tranny ground down. Ive never done a k2h, I instead chose to fully build a euro-r instead. So I cant tell you exactly what you need to do. Your venturing off into custom one off building. Im deff interested in seeing the end results though.

more pics!

 

Il update throughout the weekend, doin work

 

Mayb this will upload ? The b4 mani trimming

 

The SKUNK2 product does not fit properly at all on any H22 head?

I have yet to see one installed. Call Skunk and see what kind of answer they give you. Are they trying to sell people a product that doesent even fit and no one has called them on it?

I run the QSD KIM kit with no problems or fitment issues.

Imitators parts always come up short!!

If any of you have the Sk**k2 k2h manifold adapter and it doesnt fit contact me. I will give the first guy that contacts me a brand new QSD KIM adapter for their SK**k2 adapter ( as long as it hasnt been all hacked up to fit)) so a side by side comparison thread can be started.

If a product doesnt fit why is it being sold?

 

hmmm my skunk2 intake manifold fit all three of my last builds, the half jdm half h22a4, full jdm swap as well my h23vtec.


did you get a b series s2 mani??

 

The thread refers to adapter plates, made by S**nk2, so that you can fit a k series intake manifold on an H22.

 

Im sure that you were using an h22 S**nk2 manifold that bolts directly to your head, with no adapter plate.

Im refering to the K2H adapter plates that allow you to use K series intake manifold on your H22.

 

I have been under this same impression, however there seems to be some confusion. So Sk**k2 says the JDM H22 heads are different than the USDM H22 heads?

Can we confirm this?

And just how exactly are they different?

Anyone that can confirm the above questions please chime in, your help is greatly appreciated.

 

Haha I have a complete JDM H22A and a bare H22A4 head from a USDM engine in my garage, I will set the head on the other engine tonight and take a picture and double check for any casting differences, but they both are P13 casting heads.

 

ask the guys in h2b sticky forum. youll get a lot of answers in there.
