what are the bare nessecities needed to go to ITBs? obviously a modded manifold, the throttle bodies themselves. but what about the management, fuel rail, and injectors and all the vacuum lines? i probably left other stuff out too

 

Stick with a single TB manifold such as a blox or AEBS IM unless you plan on spending some money on a set of TWM ITB's, Jenvey or even Weber DCOE TB's and a properly designed/engineered manifold.

Running a hacked up stock manifold with mis matched, incorrect runner lengths to feed air into the ports from the inefficient motorcylce TB's is a big waste of time IMO.

Unless of course, you are one of the types that doesnt really care about power, flow or a properly running and efficient intake set up...

If you are just in it for the ricey factors of saying you have ITB's and what seems to be the most poplar reason for going that route (sound and trendyness)... Then hey, have a blast

 

ACTUALLY....

i have a 205whp/205tq vw vr6 on a grant itb set up. i was just hoping to get some info from teh honda side of the house as far as manifolds and management. grant even has a complete kit. didnt know if there was such a thing for a b series. just thought id ask.

 

Well then...

lol... Sorry for my rant

 

^^^ Its understandable man...there are SOOO many folks these days that hae hacked setups just to say that they have ITB's.

 

Nowadays about 75% of the ITB setups I see are hacked up and mismatched, but that doesn't mean that you can't take the time and do the research to put together a correctly functioning setup. A professionally made setup is always a better choice, but the DIY setups have come a LONG way since their first real onset a little over a year ago.

The last setup I put together cost me right at $600, but the same setup can be done for less than $500 now. With Crome becoming more and more polished with every new release, engine management is no longer a problem. Any good aluminum fabricator (of which there are many here on Honda-Tech) can take care of any fuel rail/injector mounting arrangements you'll need. Vacuum can be as simple as a Golden Eagle manifold, or something else like the vacuum line setups I always end up running.

It's true that if not correctly done, you won't see much of a benefit (if any at all), but the information is there to those willing to do the research. Good luck.

 

Do it right and the get TWM, Jenvey or Todas and save yourself some trouble and time. You will also need standalone ecu, vaccum manifold, larger injectors and many hours of tunning.
