Good write up....
Its not very difficult to make good power with a N/A build, its just that most ppl are clueless on where to start and expect to see noticable gains from ebay bolt-ons.
If you've done your research on whats available and have the time and funds, you can definitely build an all-motor street car that will hang with the mild street turbo setups rolling about town.
And the guy that mentioned the D or B being favorable over an H has definitely never owned and H swapped car. They are by far the easiest honda motor, outside of the K, the reach the 200whp mark. Especially with keeping a stock block.
My newest H setup is as follows:
92 eh2 Dx
Jdm H22 Stock head & block for now
M2B4 tranny
Rocket Motorsports valve spring and retainer kit
OEM P13 flywheel shaved and balanced to 11lbs
OEM P13 intake pipe and Airbox
OEM intake manifold w/IAB's removed
OEM TB
OEM Jdm header
Exedy Stage1 clutch kit
Chipped P28 chipped w/crome PRO, running a custom basemap by Jason Wadsworth AKA "JDogg"
Untuned with no adjustments made 179whp 143wtq
Tuned by Jason it should make in the Low to Mid 190's as is.
Keep in mind this is a stock motor with only a light flywheel and valvesprings.
I just picked up a HotShot 4-1 w/3" collector and will also be purchasing some PRO1's, a 72-68 tapered TB, Decking the head 10 thousandths, bowl work by RLZ, 3" CAI and Euro R intake manifold. After i get everything together, then i'll have it tuned. It would be pointless to fork out the cash twice when i could just do it all at once.
I'm expecting to make around 215whp off this mild setup. I'll post up some numbers when its complete.
If it doesn't make the power i'm looking for, i've been considering some mahle 12:1 drop-ins.
Sorry for the rambling, just wanted to add some H22 knowledge into the thread....
The 200whp mark is very achievable on a h-series with just bolt ons. For any H22 guys, heres a short list of proven power adders....
Intake Manifolds - Euro R, DH racing, or stock with IAB's removed and Plenum spacer
The Skunk2 loses power even on built motors
TB's- S2 70mm, DH racing tapered 72-68mm, ericks racing, etc...
Intakes - 3" cold air has been dyno proven to be the most efficient on H22's
Cams- Type S for mild, S2 Pro1's are best for stock compression, Pro2's, JUN3's
VS & retainers- Rocket Motorsports are the best for the price hands down.
S2 Ti retainers have shown early wear on H22's. >10k miles
Valves- S2, ferrea, etc...
Pistons- Mahle drop-ins are the only piston that will work without resleeving
Headers- RMF, SMSP, Hytech, AN-R/Prospeed, Hotshot, Weapon R, Jdm 4-2-1
*DC, *OBX, etc... Dyno lower numbers than the OEM Jdm.
Exhaust- Crazy, but also dyno proven. H22's love 3" exhaust. They make more
mid-range and peak HP with 3" over any other size.
Porting & Bowl work- Proper porting can improve any motor, but the gains achieved
Porting and polishing H22 heads have shown to be minimal in
comparison with other series honda motors. Bowl work, however,
has increased gains as much as 15whp with the correct
supporting setup.
thats all for now. The key with the H22 as with any N/A setup is to increase the airflow as much as possible. The H-series love to breath and thrive when allowed to.
