i think so too, my last itb cracked at the base, still can fix the damn thing but it keeps reminding me of the lansi fabricator. i forgot his face now. its best to keep it that way. :)
itb alone does not do the job. you must couple it with hi-cams, standalone ecu, and a very patient tuner!.. the last one is the most important part..
lots of so called tuners out there, you'll end up with rubbish car with no drivability on the road if you pick the "big-mouth" + "donohowtodo" type.
i managed to save a lot of fuel by using standalone ecu + itb.. using stock mivec cams. not really a kick on 1.6liter.. but the on the road driving is superbly calm if you slow drive, almost like a standard car.
Not really the case when changing to JUN. i almost have to not let go of the gas until car is fully warmed up. never ttied itb + jun cam btw. damn itb broke just before i got money, opted for 1.8 and full rebuild thereafter.
if any of you want itb, i suggest getting an aftermarket made for honda, mod the thing and dont even think of chopping the thing. make it fit to your head, you may want to mod your head also a little. this can be done at a PNP shop in usj.
good luck bros. this thread may be initially for itb, i guess evolution has changed it. :P
