I was thinking of taking my 13B out of my fd3s and put in a 20b..But it got me thinking a lot..........now I mean a lot...I know it will fit; but will the intercooler and ect will fit?? Because probably going to try and squeeze the engine in and all and that may cause delays..And the next thing; whats the biggest turbo that will fit in?

I think you need to go down one more level to the 20B forum. The links is right on top of this page...
