ok so this is what im thinking... i got a saab 900 intercooler coming to me soon so im going to do the pyrometer and the intercooler and the full load fuel screw all in the same weekend hopfully, i was going to take the turbo off and while im drilling im going to put a big magnet on the other side of where the hole will be and while im drilling the hole i will have my brother hold a shop vac by the drill bit grabbing any metal flake that will be present and then running the vac inside the manifold before i put it back together, what do u guys think?
