To everyone who has an H22. I am making ITBs for my car. If you want tips on how to DIY keep watching this thread. as I build them from scratch i will list everything i do to help make it easier for u. If you like what u see and want me to make u some just lmk. It will be awhile before i can start on another one so just let me finish mine first. I have all the tools needed to make them. A full machine shop and welding shop at my school.

so far i have spent like 200 just on the ITBs. the manifold i had sittin around. and im gonna buy blocks of aluminum and CAD them to make stacks. then just gotta buy hose and get a custom TPS setup which i already know how to do. so i could probably spend less than 500 and have them done. then i have to get my car tuned which it needs badly anyways with all the stuff thats already on it. 200 for a tune. so less than 700. and lots of HP!!!

looks like this thread is dying, but just wanted to let you in on some facts i picked up from experience.

1. You need and AEM EMS to run those ITB's. period. Cromes new program can get you up and running, but you will run like shit. Not worth the time any way you cut it, unless you get an EMS.

2. single TB and intake manifold will not only make more peak power, but i will beat an ITB setup down the track in any situation that both are built properly.


yes, the itb's are loud as hell and ultra fucking repsonsive at the throttle, but they just simply are not as good as the standard setup. In the end, when fully built, they are a waste of time.

and for the love of god, if you are gonna do this....

get an ems or stop now.

if you use crome pro with itb tools 06 then you should be able to tune it just fine. i'm using crome pro and tuned mine without too many problems - daily driven too!

but i agree, leave it to the pro's if you don't know wtf you are doing as far as tuning goes.....

the best setup is itb's and a plenum box so you can take advantage of the helmolz (sp?)resonance.

But h22's don't have as many options as say bseries, so this is definitely a low cost alternative... for bseries, something popular right now is the importbuilders modded itr intake manifold..... definitely affordable compared to itb's. ;)
