Years-S13 red tops: 91-94S13 black tops: Late 94-98S14 notch tops: 95-98S15 notch tops: 99-01
Alas, the changes/advantages of the s13 Blacktop:*
-Newer-Usually lower mileage-Usually about $500 more expensive (because its newer)-Minor ECU changes 96-98 (interchangeable with all s13 ECU’s) -Minor wire harness changes-Larger Oxygen Sensor (still narrow band, no performance gain)
10 lines below the picture... Someone correct me if i am wrong but in the sticky it says that the ECU is interchangeable with all other S13 ecu's...
