TMW makes ITB for H22A:

MODACAR sells them for twenty-two bills.

On a side note, Do they even make ITB's for H22's or is that a B series only goodie? Nothing sounds as good imho, but the lack of air filtration isn't cool.

Well looks wise it is great, but it just screams $$ and for that price I can think of alot more things I would like to do to my car

wow that is a crazy price, you had better get MAD gains if you were dropping that kinda cash,

and like it was stated before, it will prolly take forever to even come out.....but hey! its just giving us more time to save our pennies so we can buy it hehe

A guy on honda-tech tested it. It was a turbo b16, but he gained around 50hp for about 2500RPMs and his peak hp was up by 23. It had big gains all over the rev range.

There are numerous "problems" with running these on street cars. These are my observations, as I don't own a set of ITBs, but maybe one day I will.

If you try to idle the engine around the stock idle point, the idle is very unsteady and erratic. For a smooth idle, the engine really needs to idle around 2k RPMs.

Usually ITBs will really hurt the low end, although some tuners have shown the the low end loss can be quite minimal without hurting the top end much.

ITBs are made for top end power, which is usually not best for a street driven car.

There are no provisions for the EGR system, so in some states that will cause the car to become non-street legal.

There are no provisions for vacuum fittings on the TWM kits. You have to tap into the individual runners and install a vacuum log to run all vacuum accessories.

Running ITBs with a stock ECU is next to impossible. It can be done, but I do not know the particulars. A stand alone ECU is by far a better idea because the ITBs drastically alter the breathing of the engine.

Filters are available. Either individual filters for each TB, or you can buy a log manifold and use one filter.

Yes. It's funny. Cause it's an Endyn product, an IB guy came into the thread and started bashing it. "Only 23 hp gain" and the like. He conveniently ignores the huge gains EVERYWHERE, most of which are greater than 25 whp!

I just got an email from them saying it's in development for the H, K, and F series engines. They quoted me about 1500 for the H22.

They are saying in comparison with the Edelbrock, same set-up, same engine it ranged from 23whp to about 60whp....dyno proven. I have the dyno somewhere on my computer.

I dunno, I have learned to not hold my breath on any of this stuff.
