I have a 94 si with a d16z6.. says honda vtec on the valve cover.. I just got another d16z6 but the head just says honda.. I was told it was out of a 96+ex.. are there any d16z6 engines that aren't labeled? the Block is stamped, but I wonder if someone slapped a non-vtec head on it.. or is it an older motor?? Thanks!

Just look for the VTEC solenoid on the head. The D16Y8 is a VTEC engine, on the intake side only, and there are no VTEC logo's anywhere.

92-93 Civic Si/Ex didn't say VTEC either.

yup, and if it was out of a 96 then it had been swapped, D16z6's arent in 96+ EX's D16y8's are

the 2 last years of every generation they'll say VTEC on it. for example the EG 92-95 only the 94-95 years will say VTEC the 92-93 will not say VTEC same with the d16y6 i think its only 98 and up that reads vtec on it

Marauder

well, a 99-00 d16y8 doesn't have and VTEC logos on it anywhere

True

The 2000 D16y8 i got for my swap didnt have VTEC wrttin on it anywhere. i knew it was vtec becuase of the intake manifold and the soleniod. and it said D16y8 on the block

only 94-95 said it. I havent seen a Y8 that was stamped VTEC.

wait a second..then are there any huge differences between the d16z6 and the d16y8?? or any 92-95 EX/SI and 96+ EX???

There isn't a lot of difference between the D16Y8 vs D16Z6.

D16Z6 has 9.2:1 compression ratio, 125 hp @ 6600, 106 ft-lbs @ 5200 and OBDI

D16Y8 has 9.6:1 compression ratio, 126 hp @ 6600, 107 ft-lb @ 5500 and OBDII

The main external difference in the intake manifold.
