Info about ITBs

It's all in how you piece your engine parts together that will dictate whether or not it will perform well as a daily driven car. There are quite a few individual throttle body production cars on the streets. They don't have to be a 9-10K rpm track car.

The way I have pieced my setup together it is going to top out in the 8000 rpm range at the highest. They are build with daily driving and occasional track use in mind. They have 14" runners with a plenum and filter designed for mine. They aren't 8" long runners with no filters.

Its my first engine build and its what I'm going to school for too so I thought I take in what I learn and add it to my cb7. So I dont know how it will perform. I'm hoping for the best. But its going to be my daily driver when all said and done. I might also hit up the track for laughs and giggles. But that won't be that often.

If your in school for automotive, you should hit up the books that cover performance engine building and tuned induction & exhaust systems.

Everything from the diameter & length of the runners, valve size, combustion chamber volume, bore and stroke, piston design, header primary and secondary size, all the way to the tip of your exhaust make a difference in how your engine works.

My engine is not built at the moment but i got every thing i need to build it going na. Thats why i was wondering cause if i do get this i want every thing to go smoothly.

thats badass!
i love itbs. though they are expensive.
to really enjoy your itb's if you do it. your gonna want more of an rpm range
so build the head. and have a well balanced bottom end.
if you know about ae86's look and research about their itb builds.
write and rewrite and rewrite again on a peice of paper how your gonna plan this out
problems that could pop up all the above.
Now that i'm in iraq... i finally have the time to do this to my ae86

good luck

Any large mod such as adj. cam gears, cams, turbo, or ITB will require a tune for sure. There are few cars on the street with ITBs even though most are used for track use only. Get carp spone covers and xip ties to prevent rocks, flies, etc...

Concidering it is an OBX Product I would use another Fuel Rail(aem, skunk2, etc.) and any other product that is attatched to the main part of the ITBs'.

I finally made it into someones sig. Thnx Tillidie. lolz!

[vietkid_2006]

There's a member on here that has that same ITB set up with Bisi internals and he has a video of it...

[drunken monster]

Wow, very impressive. Let's say you throw in a cam and a little head work then throw the ITB's on. What kind of gain just from the ITB's could you expect?

holy f**k bro,itbs are crazy insane,now thats pure power! makes me feel like one day i'll be driving my hi power motor with itbs.may never know.

[jdmcb7lsd]

Ya I think that's everybody dream on an all motor setup definitly tune needed and I don't know how good of a tune can be on chrome my homeboy had them on his ls vtec and it was in sane that thing pulled hard and sounded deadly but do a lil bit of work and go for it bro best of luck

[jdm92_accorn]

i hate to resurrect dead threads but there is no sense in making new ones and cluttering. im planning on doing obx itbs on my build soon and posting before and after dynos. itbs can be dd'd. all you need is a vacuum manifold and attatch your map sensor to there. im actually going to try an even more amazing feat than just itbs on a dd, im going to use cruise and ac. i want to prove it can be done. if an ae111 can do it a cb can too. i'll still be doin the 3" exhaust comparison but not the 3" vs 3.5" intake anymore, sorry guys.

itb

so what kinda power can be made. i see he shifts 3ed around 90 and stock i can get it at 80. im sure its alot quicker and faster but how much.

[jdm92_accorn]

dont know because the only guy with them wont post a dyno sheet. its supposed to be 182whp and 174wtq.

[gloryaccordy]

Interesting stuff jdm92accorn.

Man, I don't know if anyone's said it but you're a real pioneer here. Best of luck with those ITBs. Keep us posted (as you always do)

nah bro, cisco (HondaFan81) is the pioneer. he is the one that inspired me before i even knew about bisi all that much. i do admit mine has more time on the street than his(hint hint, cisco get your ass in gear), lol. and man i hope they work out. i guarantee one thing, i will be the first to test the itb setup and post a sheet. im hoping to get my 3" exhaust soon so i can do that test.

[esskater892]

wow i resaw that video and its even better the second time lol.

and i see that theres alot of custom work needed to be done to have a itb set up. looks sick tho!
