Building The Ultimate H22A for N/A - Guide

[CB7Nub]

Wow lots of information, what if I just wanted about 250 HP in the H22A, headers, SRI I know what else that could be somewhat easier to install versus pistons or internal changes.

Would it be easier to build a F22Ax or a H22A for a second time engine builder? (I built a lawnmower engine before LOL)

[Joey GT-R]

Ghetto CB7: Yea that's what I meant. 12.5:1 on pump is fine. I've even heard of 13.0:1 on pump being fine in SOME CASES. But I would recommend stopping at 12.5:1. OR like you said see if you can get custom that might push to maybe 12.75:1. But past 13, yea race gas should pretty much be required.

Jordan: I guess you didn't know that Bisi's Valvetrain Package is in conjunction with Supertech, just made to his specs.

CB7Nub: 250WHP is very doable, a fully ported head head and IM with some aggressive cams should get you pretty close with the proper I/H/E added as well.

rexload: Agreed. The only time I've seen an unmodded STI, EVO or GT-R was when A: It first rolled off the lot....and B: The guy who owns it doesn't race or drive fast at all. So if either wants to race you I'd guesstimate another 100whp over stock output AT LEAST.

Thanks guys!

Darton M.I.D. Sleeved block
Wiseco 89-90mm 11.5-12:1 29mm comp height pistons
Carrillo H22 ProA rods
95mm Crank (F22/H23)
Custom Camshaft - min 0.4" of lift @ 0.5" (Web, Delta...etc etc there are a few companies that will grind cams)
Appropriate valve train to go with said camshaft (KMS, Supertech, Ferrea)
1mm OS valves (KMS, Supertech, Ferrea)
Euro R intake with 70mm throttle body (55mm-60mm Kinsler ITB's )
Properly designed header for your application - An off the shelf Bisi header won't always make 30whp on every setup.
Properly sized injectors (Dyno will tell you for sure)
Light weight flyweel (Fidanza)
5spd H22 M2B4 (LSD) trans
Clutch rated for 300+ whp (Fidanza, Exedy.....)

That should get you around 250-300 whp.

There are a tone of companies that you can order parts for H22 & F22 engines now.

[CB7Nub]

Thanks man, just what I was looking for.
If I got all those parts wouldn't it make the full engine itself then? (with other minor parts obv)

True, a 320hp H22 is going to cost an arm and a leg by the time it's all done and actually running.

Then you will face another problem.... Modded EVOs and STIs not only make power but also put it to the ground and they launch HARD from a standstill.

If you want to run with heavily modded cars in an Accord, you need a shitload of power... I would do a built F22 + variable geometry turbo setup... it can be done much cheaper than an N/A build and you will be making twice the power

not entirely true. How is really that much different from any other fully built h2x? You still have to buy all the components (some more expensive than others) with that kind of power, you have to make sacrifices in drivability and the type of fuel used.

building it the motor and building the drivetrain and chassis to put all the power to the ground is where it gets expensive.

I was wondering, if you guys could build a the best H22A for use in road cars for N/A use what parts would you guys use for the:

Camshaft: Bisi Stage 3
Connecting Rods: K20 .030 Extended rods
Crankshaft (Is this possible to change it?): K24
Cylinder Head: Bisi Ported and Polished by a CNC
Block Parts: Benson Sleeves
Valves: Bisi Oversized
Pistons and Rings: Custom 92mm Pistons
Rocker Arm: Stock
Header (Bisi of course, wait I can't find a Bisi H22A header...): theres a group buy for them

For the tranny what clutch, and other tranny parts would you guys put in? : Exedy Stage 2 Clutch, Qualife LSD
250 HP or torque would be the MINIMUM but I would like to get enough power to run with the EVO's, STi's, maybe even older Skyline's etc and beat them. Personally I'd like to run about 320 HP / torque if that sounds possible in the H22A.

I'd still like to know the absolute maximum you can hit in the H22A with proper mods, (roughly of course :P)?

there you go

[CB7Nub]

there you go

Thanks man.

No, Dnt forget seals, water pump, oil pump, timming belt, manual tention convertion, maybe variable cam gears?... High flow gas pump. Chipped ECU. SRI, and you should be set...

I was going to ask about building an H22a as well. Not looking for a whole lot of power just a little over stock, 220-250 hp, around there. What I wanted to do is get this H22a long block that needs to be rebuilt and put 88 mm pistons in it, these type S ones that have 11:1 compression. Is it safe to overbore that much and would a stock ecu handle that much compression? Should I get forged rods as well, would that be a good idea? They're really cheap on ebay for some reason lol.

These pistons are what I was looking at:

I think this would be a fun project. 1mm oversize should give it a little more power, maybe 10-20 hp more idk. Those pistons looked pretty good.


EDIT: Not 220-250 HP to the wheels but to the crank.


EDIT AGAIN: Nevermind, 88 mm is too much for FRM cylinders.

[Mishakol129]

That Bisi header makes 30WHP.........

At least according to that dyno

I don't know what other header does that

Vhat? Is this with or without a tune?

lol @ stock ecu.

I was just reading somewhere today that the H22 has two HP versions?
One with 200HP and another with 225?

[jdm92_accorn]

I'd go:
H23A vtec PDE stamped heas
Mahle 12:1 pistons
Carillo A beam rods
Skunk2 pro3s
CNC ported head with 1mm oversized valves
Kinsler 62mm itbs
Custom 4-1 header

Bam 250-260whp

He's not entirely wrong. My H27 (Bored/Stroked) ran me around 8 grand to complete in full. Custom Billet Steel Crank, Rods and Forged Pistons alone cost $3500.
