Real-World Mild NA F22ax SOHC Project Expense List

[HondaFan81]

Here is a real-life representation of what anyone can do on a F22ax SOHC non-VTEC motor with bolt-ons, retaining the stock block/stock compression and running 87 octane on a conservative tune.

Car made 152 WHP/127 WTQ on a Mustang Dyno with this setup.

Also, this thread is for reference only, not to brag. This is the basic motor build. Keep in mind these are shipped prices.




Short Video Clips:

RED 40mph+ Pull (2, 3, 4 gear)

* NOTE: Ignore CEL #7 in video above, currently fixed. *


Dyno Graph:

* Delta 272 camshaft regrind set to 0 degrees (most power), retarded and advanced by 2 degrees for comparison *



Tips/Suggestions For Better Performance:

- H23 5spd tranny or even H22 5spd (F22 does it no justice)
- Bisimoto Stage 2 camshaft, lopey idle, still daily-driveable
- Better clutch than Clutch Specialties stg 1 from LSD Motorsports (Competition stg 2, SPEC stg 2)
- Can run higher octane & more aggressive ignition timing tune
- Mill head for more compression, but then need adjustable cam gear to compensate
- Bisimoto F22ax header
- CHR Motorsports F22ax SOHC cylinder head portwork is even better now
- CHR Motorsports offers head reconditioning with EXH port only for $660.

good shit man nice list.. but it does go to show yout hat shit adds up.. man ive searched a local junkyard one of the only ones around here and i just couldnt find a cb7 im thinkin ill have to drive to seattle (2.5hrs) just to find one =[ but yea nice list is shea 2 or 4dr? and how many miles on engine?

Are you gonna replace the header on your red project? Just curious since you have had problems with the Kamikaze.

This project was done on my 91 Accord DX coupe 5spd with 210,XXX miles on the block at the time. The motor ran fantastic, that is why I felt confident in the block. A ported head was swapped onto this block, that was refreshed as well.

Anyhow, I have 259,XXX miles on this motor, so that's 49,XXX miles after these parts were installed and it still runs great. This motor sees 7000 rpm shifts frequently in nice weather on stock valvetrain (that I had inspected at headwork stage). I run Mobil 1 5W-30 and change it every 7,000 miles. Also, valve lash adjustment should be done around 12,000 miles if you rev high frequently, stock calls for 15,000 miles intervals but that is too long (unless you keep the RPMs down).

holy buckets!

thats nice, price isn't bad either.

ooh i see. well sounds like a good build still runnin strong at 259 is a good sign lol. i just lashed my valves and i think i messed up somewhere cuz now it ticks at idle kinda scared to take it high rpms now.. i gotta work on it this weekend to see if i can get this figured out.. i got 287xxx on my engine and i suspect there has been head work done on it by the previous owner cuz the whole top end looks fresh.. after i do that im gonna do my timing belt. how often is that supposed to be done?

the headwork is that just whats listed or p&p and all that stuff

It is a ported F22 head, I edited the spreadsheet/photo as someone else noticed this as well and to make for less confusion.

No. I ended up modifying it enough that it works properly now with no leaks.

1) Re-welded primary flange welds because 3 of 4 broke due to Kamikaze not providing a down-pipe brace to the block in their design. This caused bending fatigue on these welds.

2) I had a down-pipe header-to-block brace made to rectify the situation

3) Also, the fasteners they provide for the manifold to down-pipe flange since it's a 2-piece header, are crap. I ended up upgrading to stainless-steel fine thread hex bolts 3/8" diameter and metal locknuts. I used lock washers as well.


So far, it works, no gasket leaks finally or weld leaks. Been working fine for a long time now.

Added more info and video up top. Now this is a nice thread.

[The G-Man]

I am simply shocked you released this info.

Now it is time to post the spreadsheet of the white project.

I never resistent on releasing the info on this red Accord, it's a mild build and daily driver. People asked for my white project expense list more so, that is not happening. I just finally got around to gathering all the information on this car is all, something Deevergote and I been talking about with all these basic F22ax mod questions going around.

Also, keep in mind these are not all the expenses on the engine build, nor any on the suspension/brake upgrades and/or restoration. I removed expenses on the engine build that were not needed after me basically "wasting" money for the benefit of all members.

Examples: You do not need an adjustable cam gear for fixed SOHC non-VTEC motor, when 0 degree setting with factory 1-piece cam gear is all you need. You also don't waste money on cam tuning, when I proved it is not necessary on a cam REGRIND that's based of stock core. However, if you have a hardweld cam or new core cam design, yes you will. Yet, if you have all the cam specs, you can technically line up the cam to it's proper setting with a degree wheel.

thats a shit load of money to come out with 152 horses i would have just did a motor swap lol but thats just me lol

thats a shit load of money to come out with 152 horses i would have just did a motor swap lol but thats just me lol

thats actually not that much considering the A1 he started with put down something like 105 HP at the wheels. i thought it would cost more. i'll be finding this chart a TON of help in the future when i start to build my F series.
