    ITB's vs Turbo

    id liek to keep it towards the NA side so there is less of a chance to blowing my engine but i alsao heard that ITB's are hard to DD with?

    i know both need to be tuned which im find for that but w/ ITB's...there isnt any ports or vacuum for the high idle valve and egr valce and all that good stuff. so how would it work?

    im kinda tossed up between the two and i dont know what to shoot for. ITB's would be sick as hell and ill be the first accord in th bayarea with them and i love the sound when they rev but of course there is the spool from the turbo.

    for the itb's...id try and shoot for 170whp
    turbo=200whp @ 7-8psi

    this is on a f22a6 w/ bolt ons

    edit...i read this
    http://www.homemadeturbo.com/tech_projects/itb/

    brake booster can be worked from there

            As mentioned not many software producers have a map for it but they are starting too catch up and have some programs out to help. Might want to search how people run Todas and that should give you somewhat of a basemap to run ITB. I believe you can tune it it just takes some time with the EMS.

              that would take tons of custom fab to make the plenum, and would even more of a bitch to tune, but it would be tight, i duno if its worth it tho.

                Did he have to tune that at all? I'm in shock in regards to his MAP sensor setup...he sounds like he didn't tune it at all...what's the deal???

                  what a combo. this would be hard to pull off but with money anything is possible. to much effort in my opinion though. as far as going turbo. if you get a good tuner, you won't blow your engine. engine life=good tune+good tuner.

                    just buy a pulsar. its probably cheaper and easier

                    i say go turbo...there is more support for it on the site and its much easier to upgrade. probably cheaper too

                      NO GO ITB'S!!! DON'T BE A PUSSY!!!!!

                      LOL seriously though, other peeps have worked out the vacuum issue + MAP sensor issue...if I could find some definitive info on it I'd probably go for it...

                          -good high rpm power, not so good low rpm power, and on a 4 cylinder, that means you're exposing it's weakness even more, which is a big deal when you drive it daily
                          -worse gas mileage, they move air, and to make power, you have to move gas too
                          -intake noise is fun until you have a headache
                          -harder to tune
                          -still nothing compared to turbos, since your engine can only take in so much air....turbos force the issue, ITBs just increase efficiency, but are still in that same box
                          -they were designed for applications where mid-high rpm was constant....not for something that idles at a redlight or is stuck in traffic at 2000rpm for a while
                          There goes Ricky, always bringing things back down to earth

                            ITB's are good for going all N/A setup. Everyone is right though, they are hard to tune, actually, they are a bitch-ass to tune. Firstly, you're never going to idle the way you want. ITB's are great for race setups, achieving maximum air flow, eliminating a TB, plenum & runners. You are replacing it with 4 velocity stacks and basically getting as much air to combust.

                            The best ive seen that co-exist with ITB setups is using MEGASQUIRT. You can successfully run ITBS, make it tunable with MEGASQUIRT and run good MAP values...probably should repace injectors while at it. check out www.pgmfi.org

                            Forget ITBS. They are cool, but not worth the hassle & headaches.
                            GO boost...you'll get the best bang for the buck.

                              Ahhh for whatever reason I can't find a dyno of the motor from the OG E30 M3...but those cars had 2.3L DOHC L4s with ITBs, and they made decent power and torque.

                              Yes, there are vacuum and idle issues...but wouldn't you like your Accord to sound like this? I definitely would.
