    You can use the stock TPS on the bikes as Crome, and maybe others, support different ranges.

    AFAIK all butterflies have a 1/4 throttle movement so i dont see why grafting a honda TPS onto any other throttlebody would be an issue.

    I'm sure you didn't get what I was saying.

    If you had GSXR throttle bodies, using Crome or other programs allow you to use the Suzuki TPS. This means less work; no need to fabricate a TPS mount.

    There is no issue, it's just a matter of doing something more easily/keeping things simple.

    The problem with ITB's using hoseclamps like that is that the air doesn't have a smooth pathway to flow into the head - all the edges in the runners cause turbulence. If you're gonna do homemade ITB's, do it the right way and weld the runners and smooth/port them.


    HMT is such a ghetto, halfass hackjob site.

    Honda bike TPS readily work with Honda ECUs(same voltage range).

    If your runners are straight and ends cut to fit the clamps, they will work perfectly fine and be smooth, as seen in stock applications. Problem is, people use clamps as adapters. This makes transition even worse when the runners are bent like the OE runners that are cut to "fit" ITBs.

    Also, an alternative to welding and clamps is a flange/bolt system like how AE101 ITBs are connected.

    Or you can grind the lips down in the runners to make the transition smooth.

    Always wanted a set, but on a stock Integra it would be rather pointless.

    I was gonna make ITB's for my car before idecided to go turbo. If you want to go ITB you gotta red up alot on it. I still have my throttle bodies from when i was gonna build. there off a honda 929 cbr so the TPS works. if any one is interested and wants to know more PM me here is a link to another ITB build that you all may be interested in.
