Default CB7 H22 - Jordan Tuned + modified IM



Special Thanks to:
Chris Carey & MAP staff
Tou - P.R.E for consulting on the H22 manifold design
Jordan
Croy & Jesse for helping me with the IM install
Derek for letting us use the 3” VS
** more pictures will be up later tonight **



For the 4th session of Dyno After Dark, we wanted to bring in an H series setup so we can test MAP's prototype modified H22 Intake manifold.
Austin’s car was a great candidate because after the recent body restoration, he swapped in a fresh JDM H22 motor.



  • JDM H22
  • H22 intake manifold & throttle body
  • Bisimoto header
  • 3” full exhaust
  • 3” BLOX VS
  • Hand Command chipped P28 + crome
  • Powersteering still attached
  • Balance Shafts still attached
  • 92 pump gas
  • non B series tranny



Chris of MAP was also very gracious in accommodate the afterhours tuning session as always & gave behind the scenes tour of MAP.
Tuning started at 7:40pm
Base line tune with P28 + handcommand base map






Jordan wasted no time cleaning up the base map & adjusting vtec in order to provide more usable powerband.
I recall telling Austin not to hope for too much since h22 cams aren’t all that great. And that anything above 180whp would be good.
I hope everyone enjoyed watching the consistent gains of each pull.



After about 12 WOT pulls & 6-8 partial load pulls. We ended up at 190whp!
We weren’t done yet though. We had a manifold that I wanted to test out.


PROPS to the fab department at MAP & Chris for being able to modify this H22 manifold in only 2 days notice. Easily 6 hours of work into the manifold, it's not prefect but this is just a prototype. I know they are ramping up for spring & their fabrication order qeues for manifold/downpipe and porting is already stacking up. Chris really stepped it up, making sure I had a manifold to test out in short notice.







Unfortnately, it took longer than expected on swapping manifold. We started at 8:15 and finished the swap at 9:30pm.
I wanted to thank Jordan for his patience in waiting, luckly I had one of the P.R.E. guys do a food-run haha.

We swapped on the current H22 throttle body & injectors to the new manifold, reusing stock TB & IM gaskets.
The 1st pull with the modified IM was +6whp, after a few touchup it ended up with +10whp gain.





By the time we got done with the IM swap the crowd lessend from 35 to about 15. I had a great time meeting new people.
Thanks for everyone on coming out and supporting MAP's Dyno-After-Dark session.

So what did you do with the bottom part?


This is what I did to mine.

This was just a PRE & MAP prototype.
It's not very pretty in the inside. They don't want me to show the inside YET until it's refined.

60% of time/effort was cutting & heavy porting
30% of time/effort was welding
10% of time/effort was light porting by the runner divider

We did weld up the EGR and IACV
No porting done to the TB inlet since we are using stock TB.
No porting done to the runners to open them up.


I was looking at your STYLE of manifold too.
But from my understanding he reason why the h22 IM chokes out power after vtec is due to not enough pelunum & too much runner.

Shawn, please correct me here .... I'm new to H series

Ideally, most IM designes which have larger pelunum and wider/shorter runners will help out in the upper rpm powerband (provided you have enough RPM, CAM & COMPRESSION)

So from what I can tell with your desgin (assuming)
if you middle dececk plate is also the same OVAL design, al you did was enlarge the runner lenght NOT add to pelumum volume. The benefits?... maybe more midrange but not sure how it would help out up top +6-8K rpms.


Another design Tou from PRE was telling me about was removing the middle deck plate, opening up the top pelenum, cutting open the RUNNERS similar to what your is, but staggering the dividers.

Maybe we'll try something like that down the road.

I really like what you did. Saved about 600. for just about the same thing. Dhracing intake manifold was that price.




H22A
P28 ecu chipped
Camp 1320header
Flywheel 12lbs
Skunk2 exhaust 2.25in
Dhracing intake manifold
78mm tb

I wish I would of had 3in exhaust I'm up grading to that right now. From Turbo system





This a pic of it. Not mine sake thing but I milled the runners.

Thanks for the compliment... I'll pass that on to Tou & Map...
didn't design it or do any of the fab work. lol

I found out the same thing, more plenum volume + more top end, but it also came at the price of alot of midrange loss. Its a balancing act. I'm running the shorter/smaller plenum setup because it killed it in the midrange and thats where I need the oomph to get the heavy lude rolling haha. I still havent gotten to test them same track same day, but from teh testing I did do the smaller plenum made teh car faster, evern though it didnt quite carry the power as far in the top end.

NaH2B's manifold is gutted out clear to the bottom which I'm guessing thats what you are going for? In order to that you have to weld the areas between the runners on the underside of the manifold. I'm not a welder so I've never taken it that far but there may be more power to be gained by doing that. I do like the stock manifolds for the simple fact that they can be taken apart.

What does MAP have for equipment up there? Are they doing this on a CNC??

Tou said that even though this manifold "appears" to be promising he said it probably won't do well on a more serious motor when shooting for +260whp applications.

He likes the K manifolds when he compared them both and measured out the volume of each. BUT he said he would need to modify the K manifold to get the most out of it.


Yes it's similar to NaH2B, but just not as fancy.
Tou-PRE does have a few changes for it in mind it just to clean it up.


MAP is my home shop, mainly because Jordan is one of my best friends of 8-9yrs.
Also Chris at MAP has been very flexible with getting me dyno time for testing at no cost.
I just have a good relationship with them.

They have all the equipment you could think of...
15,000sqft
31 FT employees
they are big in the DSM, STI, crowd and the even have this fancy machine that turns a block of metal into a built wheel. lol


I'll ask the FAB guys what tool they used....to do the cutting.

How much did the dyno plus tunning cost ?

it was a special price for dyno-after-dark session
it was only $140 since it only took 1 hour.

then i just bought jordan dinner to hang out for a while for us to swap manifolds and he retuned it which was 3 pulls or so to get the +12whp .....hehe
