So here it goes, In compliance with Cali's new State Ref laws that have been amended i puled out my JDM B16A since i already had the head off and was in the machine shop being checked out. I put in its USDM sister B16A2 counterpart, got it all put back together and running but at an idle which is about 750 rpm, if you floor it it stumbles for a second before it will actually pick up and rev up, but in the higher RPM it revs fine how the other engine used to. the main concern is the Stalling out it happens when i am coming to a stop or just step on the clutch that RPM drop and will sometime stall out, which becomes a pain in the A$$, when you manage to caught every red light on your way to work. Before the engine switch i never had a problem with it, now what can i do to about the stalling out that is one of the main focus right now. i have clean the IACV to eliminate that and see if it help but it still drops and stalls out. timing is set at 16* this motor feels a bit weaker then the other one.

ACT 12lbs flywheel

things that have been changed during the switch
Comp clutch stage 4
ARP head studs
