I've been on this site for a few months now learning more and more everyday. I checked out the "How Too" list on cheap and easy upgrades. Well lets just say I have around 7k on a complete rebiult JDM motor(worried of another bhg) rehoned cylinders, chromoly rings,HKS 1.2mm hg,ARP studs,MSD wires,NGK plugs,electric fans,cold air intake(front bumper) and full 3" from turbo back,hard upper pipe w/Greddy Type-S and a few other little things. Well I was reading up on shimming the wastegate to get more boost and tapping out the MAF to get more air(we run rich right!) Anyway I couldn't believe how easy all that stuff was to do. I had extra longer bolts layin around the garage so I shimmed it to (5) 8mm washers and holy shit did it make a difference. Before my gauge would just barely hit 8pds now it pegs out so fast I think the needle is going to break off. Is shimming my WG going to do any damage??? I checked my turbo which has NO shaft play at all and spins very freely(low mileage from JDM motor). I know you should boost hard on shitty turbos. Thanks fellas Later-T
