How does MZR with VVT/VCT work????

[bpr0422]

Personally I'm new to mazdas...

I'm totally confused on how the vvt cam works...

So far i've found out that vvt is only on the intake cam.. with one profile... which is either advanced or retarted a few degreees by the ecm/ecu...

its totally different from Honda's VTEC with 2 cam profiles... and diff from honda's i-VTEC with VCT on the intake, considering i-vtec is VTEC with VCT on the intake...

however hondas VCT is retarted or advanced hydraulically...and mazda's i have no idea...

explain please.... cause.... whenever you go to a honda site.. they explain fully the myths and truths about VTEC and i-VTEC...

I hear that only our intake adjusts. So if that true and the exhaust doesnt would it be possible to use a performance exhaust cam from the focus or would that be a bad idea. I would think that the valves would go instantly depending on how close the focus cams are to our cams. But then again im not an expert, what is yalls opinions on this?
