I plan on doing a large turbo setup and research has led me to believe that the TB will be the largest bottleneck on the intake stream with such a setup. They make larger ones for the D23 (Which is what will be going in) and was hoping I could convert the TB so that I can go bigger as well.
And I have an MTX, but I can still tell the delay after driving it for a year and getting used to it. I actually gas a split second before I know I need/want power. It may not sound like much, but in an autox it makes a huge difference; and even though I can accommodate for it I'd much rather have throttle on command.
