take 4ag out, insert 4agze, sell 4ag, sell supercharger and other peices, buy t25 or ct26, buy manifold off ebay and re-inforce the welds, use piggy back.
orrrrrrrrrrrrrrrrrrr
buy manifold off ebay re-inforce welds, buy ct26 or t25, buy gze injectors/mkiii/mkiiii/3sgte/whatevers cheaper (prolly gze's), buy walbro pump or use TII/Supra turbo fuel pump, buy a safc or somthing to compensate for your new injectors and pump, id go with a FPR just to be safe too, use a topmount off a GZE or 3SGTE and get piping made or use a starion fmic, buy a bov, keep it at 5-7pnds. for insurance i'd get some ARP headbolts and rod bolts/thicker headgasket, gasket kit, replace or inspect rod bearing wear, and you have yourself a pretty reliable, turbo 4ag, with roughly 150-170 hp. goodluck it's not as expensive as you would think
