Guest Posted October 20, 2002 Report Share Posted October 20, 2002 Hi , I just bought a 90GP with 65000 miles as a daily driver till my street strip Z28 is finsihed . The car is about perfect but sinice I cant leave well enough alone I want to upgrade it some . Here are my questions . Is this a 3100 or 3.1 ? How much HP can this engine support on nitrous oxide ? Has anyone here done cams , heads or intake changes on this engine ? I found a Super Charger but its $4500 and only 80hp more . I want to change the wheels too . Anyone know what sizes will fit without problems ? Link to comment Share on other sites More sharing options...
Guest Anonymous Posted October 20, 2002 Report Share Posted October 20, 2002 Go pop your hood and the intake will tell you if it's a 3.1 or 3100. It should say 3.1. Link to comment Share on other sites More sharing options...
Guest Posted October 20, 2002 Report Share Posted October 20, 2002 Yes this I know . Its a 3.1L engine but I thought there was a diff between the 3.1 and "3100" Link to comment Share on other sites More sharing options...
Guest Anonymous Posted October 20, 2002 Report Share Posted October 20, 2002 There is a difference. If it's a 3100, it will say 3100 on the intake. At least my '94 Cutlass does. Link to comment Share on other sites More sharing options...
gp13069 Posted June 28, 2008 Report Share Posted June 28, 2008 if it's a 1990 gp the in take reads 3.1 multi port F.I. but in it's a newer say 1996 & 1/2 engine it should say 3100 with the coil packs on top of the intake. Link to comment Share on other sites More sharing options...
