Isnt that V-Tec ?

I thought Only Inlets are V-Tec...
Who gave you this idea that if its inlet only then is VTEC YO!!!!!? VTEC YO!!!!! are Honda, not Mitsubitsu.

Most Variable Value Timing vehicles are inlet only during the 90's, only a few have both in and out, but mainly for marketing purpose and don't do much.

The FTO has both Variable Valve timing and lift on both Intake and Exhaust as in the pic, top cam is the intake and bottom is the exhaust, both have the same gear, also another sign is that the cams both have the low speed and high speed cam lobs.

there u go..

As the pic clearly demonstates the GPX has it on both intake and exhaust...thanks bigpitty1 for that pic.

I too was of the impression it was on on the intake but I did know the new versions of MIVEC we not as cool (aparently) and maybe this is what they wer eon about...

it also has lift control....

It was a good read, i didnt understand how it all worked...its quite cool actually.

And did I hear correctly in that the 'new' mivec is electrical only? Ie there are no secondary lobes on cams its just the ECU advancing timing?

here is some info...dont know about no sec. lobes though...

I think cam phasing is what thats all about...Nissan has had it for a while...VVT I think they call it.

from what I tell its continious cam phasing....and the gains are not as great but smoother cutover...

The newer M3s have inlet and outlet...while the older ones only had inlet...according to the BMW page I read anyway. Its all good stuff.

I think there were a lot of VTEC YO!!!!!'s with only on the intake, like there SOHC VTEC YO!!!!!'s and possible also there non sporty cars for example any thing that was not a TYPE R.

I think they still do this with there new cars as well like the DC5 integra, the base model only had VTEC YO!!!!! on the intake while the TYPE R had it on both.
