and what do i need to do to make the swap work anything special
let me know any info helps

AJxr

im 99% sure there is no difference between the z6 and d15 vtec head and if there is it is the cam. unless of course its the daul stage d15 vtec head which would be baller... or lame.

D15 Vtec is 1.5l, Z6 is 1.6l. Diff is in the block not the head from what i remember but dont quote me on that.

so do all the water and oil holes from the block and head the same

laports_best_crx

yes its all the same

dont forget to remove the oil jet, look for write ups online. im sure you dont feel like taking the head back off after you get it all together.

AssHat!!

The oil jet is inbetween and just right about cyl 2-3 Just take a screw and screw it into it and pull it out. Thats about all there is differnt than a regular head swap. Minus wiring up vtec. But IMO i wouldnt waste my time with this swap. Ive done it and noticed very little gain. But hell if you got the head already then gofor it

Oh and if you use the z6 head you need the z6 dizzy.

so that means i cant use the obd0 dizzy from my si right
in other words i have to change the car to obd1
