Converting the ZDX to full VTEC

[AcurazDriveR24]

Hi.
I have seen mixed info, but it seems like the J37A5 in our ZDXs only has VTEC on the intake side, unlike the RL and TL which have full VTEC. I read that converting the ZDX to full VTEC would be easy. Has anyone here tried this, and how difficult is it? Thanks!

Swapping to full VTEC sounds like a fun idea, but will the extra power gains really be worth the effort? The ZDX’s ECU might not support it without serious tuning, and even then, I wonder if it would really make a noticeable difference.
