Does anyone know where to get these from? I've seen a few pics around of them being on the B16B, H22 and most DOHC's.

Can you buy it? Or have people just made them up? DIY. :nice:

those ones are from TWM iirc - other popular ones are from Jenvey.

I'm not trying to be a dick either... 'tis better to teach a man how to fish.
 
I tried Google to start with but couldn't find anything on TWM, anyway got the other websites shop.

Thanks for the info mate.

Impossible to say, it's down to a lot of variables. ITB's in my opinion should be the last stage of NA tuning.


And yes google Jenvey Throttle bodies, or TWM individual throttle bodies etc. Easy enough to find!

Why would you say its the last stage of NA tuning? would ITB's not be recommended for road/daily drive use?

Yea you can find Jenvey Throttle bodies, or TWM individual throttle bodies through wikipedia.org also. just found their websites just now. pretty interesting!:)

Simply because to make the most of them, you are going to need to have I/H/E, engine management system like OMEX, headwork, cams etc etc. Not to mention they are quite expensive.

As for use on a daily driver, I don't see any reason why you couldn't! They are very loud, but some like that :) More than likely you will also see a rise in fuel consumption.

However, you can gain in my opinion about 20whp! And throttle response will be unbelievable! A friend of mine is running ITB's on his daily driver that he has manufactured himself, and he is yet to have any problems. (Although he did have a massive fire in his bay :lol: but that was down to a fuel leak not the ITBs!)
 
ITBs themselves aren't that expensive. It's their supporting "cast" that makes them pricey to deal with. Fuel system and ECU remapping makes it a bit of a daunting task overall.

Their inherent low vacuum signal makes it difficult to tune off the MAP sensor so Alpha-N (TPS only) has to be used for certain parts if not all of the re-mapping.

But if one happens to already have an upgraded fuel system and a programmable ECU (going from Turbo to NA) then even with mild cams or even stock cams and no ported head - one can benefit from making more midrange power. Top end gains are generally realized when portwork and big cams are used.
 
coming from my last car, being on itb's this looks very interesting!! i love it loud and i bet that would scream on vtec :D

something for the future maybe....

agree 100% nice wiring set up, clean as it can be, damn sweet.........just love how order this engine bay is..

Anyway, ITB can be said as the ultimate intake option for NA cars (Turbo cars can utilize ITB's too, example RB26DETT comes equip with ITBs just that they have a large intake manifold around it), a precisely tuned ITB can giv u power and torque improve from low end to high end, alot of cases are where ITB loses power and torque during low end as there are just too much air, however i've seen succesfull attempts as well as articles on them, taiwan's F1 Motorsport EK is one example, the trick? A very good management system....

Note ITB are also to be said to increase rev limit, although fuel consumption can still be abit bad compare to non ITBs (in the case of a fine tuned ITB), breathtaking intake sound and response severely counter that....
