What does this all mean? No one has done it. Therefore any guessing done to the power output of an ITB 4G84 is mere speculation and cannot in any way be taken as remotely factual information.
I think 200 whp would be one hell of an N/A build for a 4G64, those motors are unlike honda's in their ability to rev, making boost even more of a necessity to make power.
Now, if you wan't to make N/A hp you are much better off building a V6 as 300 ish whp is an attainable goal. With greater displacement and a fondness for rpm the 6G72/74 would be the application to spend money on ITB's.
Panda, you really have no idea the amount of headwork it takes to make big power N/A, on stock 4G64 porting ITB's would show no real gains over a well designed plenum manifold. Yes you can do it, but why, a plenum will outflow the heads if a throttle body and MAF are properly selected to match, its senseless to endure the extra cost of running a standalone ecu as well the added tuning issues.
