H22 plans...

[SuperTuner12010]

Ok guys since school destroyed my original mild build up on the H22. Iv decided to just put the motor in now with the timing belt conversion. But in a month or two I plan on buying a few bolt on parts.

I am looking for those best bang for your buck kind of mods. Like buying a megan or dc sprts header, cutting off the original collector and wlding on a 2 1/2 or even a 3" collector, with a custom 3" catback. I remember this was tested and that the 3" netted more hp than 2 1/2 cat back.

These are the kind of mods im looking for. Or any mods to increase the durablility and reliability of my engine.

:Plans as of now:
-Cheap header cut at collector with 3" pipe welded on and a 3" flex pipe in original location. Continued onto a full 3" cat back.
-Either euro r intake mani? Or Stock with IABS removed.
-Balnce shaft removal kit
-EGR Delete...not until tuned on p28
-3" intake
-Tb Coolant Bypass
-62mm bbk throttle body
-Weapn R throttle rotor
-Polyurethane filled motor mounts

Lets compile all kinds of info on benificial mods for the H22 that are at least benificial...

you must be running some big turbo to run a 3" catback. who told you it would gain hp on a na motor? if it was like stroked with some beafy cams than yea 3" is good. but stick with the 2.5"

euro r flows better

70mm throttle body

thats what i want. a euro r manifold and a bigger TB. after that i'll think about a few other simple mods then call it a day with this car.probably sell a year after lol

[jacobuchanan140]

there are other IMs with more hp gain per dollar than the euroR

look at blacktrax h22 IMs

Here is the link on Honda tehc, he gained 5hp going from skunk2 cat back to crushed bent 3". There have also been many threads about using cheap headers and changine the collector to 2 a/2 or to 3 inch.

I had alos planed on the throttle body coloant bypass. Just forgot to add it

But does that billet throttle rotor really do that much? Any proof?

[accord2nr81]

i cant give you any proof but i can tell you i love mine and i will never take it off all it dose is get you to WOT 50% faster so you barley tuch the gas pedal and it wants to go i wouldnt reccomend anything that i havnt used in the past and this little trinket will never leave my car

After the collector, you want the piping to be as free flowing as possible. There is very little exhaust tuning you can do past the collector, It is just a restriction.
