How do you install eaton m90 supercharger on 1997 Pontiac grand prix gt?

Answer 1

You have to do a top swap, basicly find a L67 enging (GTP) or the following parts, (plus some custom electrical tuning.) -L67 idler pulleys, L67 idler stand off, L67 throttle body, L67 injectors, custom PCM, GTP balancer, L67 MAP sensor, L67 heads, L67 fuel rail, 2 head gaskets, head studs, MAP adaptor harness, bypass valve wiring, vacuum lines, brake booster line, supercharger gasket, throttle body gasket, lower intake gasket, lower intake Orings, supercharger belt, GTP valve covers, GTP valve cover gaskets, coil pack bracket for 99+ cars, M90 from an L67, lower intake from an L67, M90 bolts, and new rocker bolts. You'll also need a torque wrench, 3800 balancer pulley, and very powerful airgun to remove the crank bolt. Or go with ZZP's install kit, in which all you need is a lower intake mainfold, supercharger, pulley, cam, fule logs, all from zzp and custom made... ported and polished 2, though the original top sway is still cheaper and the ZZP kit is slightly more limited...
