What kind of VTEC does our TSX's have?
the new K series has the i vtec that i know..
but there are versions of it, ie vtec-e (not sure of the correct name)
which is found in the k20 160hp model (Civic Si, RSX Non-S)
where Type S has another kind of Vtec which is more performance
oriented... and has vtec on both intake/exhaust (dono how that
works either) just wondering if our version of k24 have those?

All of the K-series engines have what is known as i-VTEC (yes, the "i" is for intelligent). The difference between i-VTEC and VTEC of past comes from a new integrated system called VTC (variable timing control). This new supplement enables the intake cam to be constantly variable, rather than having to hit a certain rpm to engage its higher output modes. In addition to the new camshaft-timing system, the engine is now driven by a timing chain (rather than a timing belt). It also has 3 modes of engagement of its output modes, as opposed to the 1 mode that the older VTEC systems have ( that hit at 1 rpm to get full engagement). It enables smoother acceleration, a flatter torque curve, and a feel that a 4-cylinder engines are not known for (a buttery smoooth torque delivery without the jerkiness normally associated with cars that have high torque peaks with no flatness). Not only is it a great way to improve the feel of a little engine, but it also has more spaced-out maintainance intervals and lower emissions with improved fuel economy. Honda has this new system that is a win-win for consumers. You still get a fun 4-banger that is not only easier to own and maintain, but is also better for the environment. Not bad for the little motorcycle company that could.

it's pretty much the samething that toyota has in VVTL-i or the vvti which has been around for about 5 years now with the constant variable timming instead of the old vtec rpm engagement point.
