90 Lego OB ej22e heads
Delta RV cams
99 Lego OB ej25 block
90-91 Lego 22611AA563 ecu, MT
99 Lego OB y-pipe or OBX UEL SS headers
90 Lego OB eng wiring loom & interior loom
Granted OBD 2 is now the preferred system to harvest for this, I'm attempting to stay within the 5 yr span according to Calif ARB guidelines to make my swap smog legal. My 87 gl can have up to 92 OBD 1 without the arbitrators/inspectors throwing a hissy fit.
My question is would a 92 Lego intake manifold with throttle body have better IAC adjustment than the 90 Lego OB manifold?
Just in case I need to bump up the idle speed to compensate for higher compression & RV cams.
