Duuude, you should know better then that! IRTBs isn't about ultimate power, true, but the throttle response and liveliness of the engine are untouched! Heck I've driven a stroked Honda B18C engine (210+hp) and its NOTHING compared to an IRTB B16 (175+hp).Matt [exz3owner said:@ Wed Aug 09, 2006 2:10 pm]damn. thats how I shoulda ordered my stroker. too bad I wanted ultimate power, not ultimate cool factor...
I think the butterfly's in the throttle bodies are replaced with a rotating barrel to allow air in ... can't remember why this is more of an advantage though and they still don't look as nice as R S Aizawa ones :wink:So whose IRTB kit is FM using?
And what does roller barrel mean?
