all that i know if its d15b 3stge Vtec.. there are 2 vtec solenoids.. d16z6 have only 1 solenoid same as d15b sohc vtec at early production

but.. if i choose 3stage vtec.. i must change my ECU too if i want the "3stage" active

and what the different between them

but.. from the outer skin/ phisics, how can i determine which is d15b and which is d16z6.. ? is there some 'mark' on them maybe ?
