im lookin to built a straight drag engine
h26 stroker kit 100mm crank stroke darton sleeved 89mm (pocket rockets racing)
15:1 compression probly gona be higher i know ill have to notch the pistons for the valves
ported head possibly itbs not sure yet
stage 3 crower cams retainer and springs
skunk 2 im
removed balancer shafts
egr delete kit
supertec flat valves nitrade coated
header unsure
h2b conversion
im still fugureing out everthing but its gona run on straight race fuel

my goal is to get my crx into the 9s without a turbo the car currently weighs 1850 with me in it and full tank of gas

im also going to use a 150 shot of direct port nitrous so on spray im lookin for 500whp hopefully

anyone have h26 whp dynos?

 

forgot valves will be 2mm i and .5 e oversized

 

what header will you use?? I dont think your crower 3s will be enough 2 push you 2 350whp. you need to look into major head work along with a custom intake sysem and camshaft specifically setup for your setup. but anything is possible and good luck with your build. by the way what rod ratio will you be running with your 100mm stroke??

 

Is it possible yes. Is it economical, no. Trial and error costs a lot.

 

RLZ headwork

 

billet carrilo rods that come with the kit goto pocket rocks racing.com they got one on 93 gas that made 340bhp so mine should be pretty good
but im still researching things like the cams n stuff im just tryn to get ppls ideas to help i pretty much no the bottom end right now

 

anything is possible but it's uneconomical and she gets very thirsty...whats wrong with a torquey 240+whp setup???

 

well its a drag only car and i want to get as much as i can and if im not happy ill drop the compression and change cams and turbo it but i like the hard launchs of all engine setups plus i havent seen a honda around here in 9s without a turbo so im gona try

 

look at this guy reccomending another head porter for high horsepower H22 goals. I think that says something. Sam Walton never said shop at K mart.

Big Thumb Steve youre the man.

 

pm 2fastgsr, he made 350 doing something similar but i also believe he made a 2.6 outta his h22.

 

thx i will i open to all opinions and ideas thx

 

going to need much bigger cams than crower 3's. Look into bisi's extended rocker arms.

 

Absolutely.

Either that option, or roller rocker arms. You can change the rocker arm ratio and look at some of the serious custom big cam profiles.


Also, you should look at Jenvey ITBS and Custom Header.

 

what is it basically just a different rocker ratio (higher) ?

A 100mm stroke and 89mm bore will make 2.49Ls

 

The roller rockers will alllow you to run a higher rocker ratio, thus a bigger cams.

 

OP, one other thing, you mentioned going boosted if you don't reach your goal.

I want to warn you upfront. The components ie crank, rod, pistons, head porting, cams, etc that you will be using to get 300+ whp are incompatible with boost. Especially, the level of boost you will need to get into the 9s. So, if you goal is to get into the nines then you need to make absolutely sure you want to go all-motor. It will be a very expensive bill with no recourse for using those parts in a boosted build.

 

you will need to go bigger than 89x100 to make 350 whp. there are some companys that are willing to make you 103 cranks. and golden eagle has a big bore kit that allows you to go 91mm. you will need alot of headwork to go along with your block. you will also needbigger camshafts than crower 3's. intake manifold and header comes into play and alot of other misc things, h22s are undiscovered motors. of RnD went to h22s like K series i think the h22s would be something to mess with. the accord 2.0 touring cars made 300 hp. h22s just need alot of RnD. enough about that ive been drinking and now its time to go to sleeep

 

I think you have a lot more research ahead of you my friend.

Is it possible to make 350 out of an H? I firmly believe the answer is YES. With the reviving technology for the H right now, many things are available now, that werent available to the H pioneers in the early years.

However, you MUST realize that if this is your goal, then you are pretty much going to have to build this motor and expect to have to push it to the extreme.

So here is my take on your original post. I am not being a dick , just want you to have correct information.

-89x100 is not 2.6L, it is 2488ccs
-a 90x 102 motor is 2.6L - 2595cc
-If you already have the 100mm crank then go 90x100 = 2544ccs.
-Pocketrocket racing made 340hp on an ENGINE DYNO. Not to the wheels.
-Crower 3s will by NO means get you to your goal.
-Skunk2 Pro3s will be your cheapest option. In a perfect world you could go with the Crane roller rockers .537 lift special order cams or have web design you a custom grind.
- When dealing with a motor that you want to take to the extreme, you have to think outside the box to get you there.
- The s2 manifold made great power on my stock/mild builds, however I think that there are no decent manifolds that will flow into the range in which you want to obtain. I would definitely go with ITBs, 54mm+. Try to get the Kinsler 60mm+ if possible
- Header is CRUCIAL. Talk to Danny @ SSR to have him make you a custom one. I have my Ericks Racing header I used for sale btw
- If you are using it for track only duty, why not get a larger fuel pump, injectors and just run alcohol?

Just as an example I made 318hp/228ft lbs tq on my H . Here is what it consisted of:

90 x102
15:1cr
Portflow Head work
52mm TWM ITBS
Ericks Racing Header
Custom Drag Cartel cams

It could have easily made 330 with a set of rollers.

Good luck. I hope your checkbook is ready for it . .

 

Simply put it this way...



You will be.. going, where, no man.. has gone before.

 

if you have deep pockets anything is possible dont let anyone tell you its not


also keep in mind you need to have money to fix it when its breaks or maintenance etc

 

so you want to spray on top of the 15+ compression ratio?
oh boy

 

ty 2fastgsr u did a nice build by the way

 

what about that 2point6 guy? didnt he make over 300 whp on 13/1 compression?

 

listen to this man when it comes to H series

 

Yes , Scott is another great resource to go to . .
