RE: bolt on power????

exactly! the only thing its going to do is go to the intake so if the intake can't flow then it slows there.

RE: bolt on power????

The main thing w/ the TB size is that too large of a TB will decrease your velocity b/c more air flows in than some setups can flow. W/ GT40 heads and an aftermarket intake, I would go w/ a 70mm. Also, make sure you're running a MAF at least as big as your TB....a larger TB is pointless if you can't get air past the stock 55mm MAF.
