0.03mm lift on the VTEC lobe is insignificant.
toyoter91 already showed you that the TSX cams get raped just as badly by an aftermarket cam as the stock Z3 cams do. And like he pointed out, the majority of people can't swap a set of cams on their own and install cost/tuning makes the TSX cams look like a silly option when there are aftermarket cams that will out perform them everywhere in the powerband.
first off, cams dont get raped. if they did, tsx cams would do better than z3. stop ignoring low cam, primary, secondary, and even vtec lobe improvements over z3. tsx cams will outperform z3 cams everywhere but the vtec lobe, where gains are minimal.
many people like tuning cams themselves. do not tell people what they should do with their money. there are drivers out there that prefer OEM reliability and would rather not spend the extra money on the valvetrain, aftermarket cams and the install of the valvetrain. It is not so black and white as you claim it to be.
once again vit, you use "silly" in your defense and this is pure opinion. keep this crap out of cam comparisons. thank you.
the change in vtec lobes is marginal in terms of lift, however once again you fail to read the whole post. the duration on the vtec lobe of the tsx cam is much greater. duration = top end, AKA: how long the lobe holds the valve open.
you cannot measure duration with a micrometer, duration is how broad the lobe is rather than how tall it is. the height of the lobe as measured by the micrometer determines lift only.
Thanks for your clarifications. I've realized thorugh several posts that you know your stuff for facts.
As I said, I already ordered the intake TSX cam, so it'll be installed. But, unfortunately, it wont be until Feb when a tuner from Puerto Rico visits Panama. I think I'll be one of the few (if any) with a k20Z3 SC'd with a TSX intake cam. So evenetually, I'll post results.
However, I wont be able to measure the gains with respect to TS intake cam for several changes from best dynojet run of 272whp STD, such as:
Now / to be change
Reflash Stg 2 / -> Flashpro (already installed)
Strupp header / -> Sunk 2 Mega power header
Greddy Evo 2 / -> any good 3" exhaust system
Stock cams / -> TXS intake cam
I could install, tune and dyno'd pre and post TSX intake cams, but it would cost me more tuning and dyno time.
Let's say that if I get to reach the 300 mark, I'll be happy....j/d (I'll be very happy at around 290)
Don't worry about not getting a before and after dyno. You would be spending all the extra dyno and tuning money just to prove other people wrong. I wish i knew more about overlap, because many people think using the Type R exhaust cam is a great idea too. I'm just not sure how that will perform with F/I. You will be very happy with those upgrades though, i can easily see you hitting 300 with those upgrades.
