ITB's are individual throttle bodies. This means the motor would have 8 throttle bodies instead of 1. There are some threads out on this for the 1UZ. I believe it has only been done in Australia. You can check the Lextreme forum for much info on this.

BTW, ITB's are an expensive way to go....Plus, without making a whole lot of other changes along with them, you still will not get to 350 WHP.

OBX makes ITBs for the 1UZ now, I think they are about $1200.

I would put the 4.7L bottom end in and use your stock head ecu/harness. Then I would modify the top end. There are companies that makes cams, oversized valves, ITBS, etc. I am not sure how close this will get you to your HP goal, but I bet you could get pretty close with the 4.7L bottom end...

Um, I made 350 rwhp on the dyno way back when. I'm now pretty close to 400rwhp, estimating by an 8-9 mph improvement in 1/4 mile track speed since then.

I am using the SMALLEST supercharger Vortech makes.

Also, if I'm not mistaken, my SC400 FI build cost way less than most. On this forum at least. Bracket = $100, used supercharger from ebay = $950, piping kit from ebay = $100 or so. Maybe another couple of hundred dollars for a belt, pulleys, and some other misc stuff. I spent more than that total but could do it way cheaper if I had to do it again. Also does not include a ton of other supporting mods which would / should be done anyhow. Still on the stock ECU also BTW, been daily driving it for I think about two years now. Lots (a couple of hundred, no joke) track runs.

like most of what these guys said.

i think headers, full mandrel bent exhaust and some Nitrous will give you 300 or close to it..oh and a BFI.
