Vtec like 240?? - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

I can feel a big difference in how my car pulls right at about 5,000-5,500 rpm.  Almost feels like a vtec from a honda (not to say its ANYTHING like a honda)  I've driven a lot of honda's and I actually feel a difference that rivals a prelude hitting vtec.  very odd??

btw, I have a 92' 240 5-speed.

Anyone else get this?  any explanations as to why?

I believe that has been traced to the swirl control valves opening up.

What rpm do the 2nd intake runners open up?

A handfull of Honda's use dual intake runners to boost up the air delivery, but in no way would I say it feels like VTEC.  The engagement is much more pronounced.

I would have to say, there's no feeling in the world like a T88 kicking in.  Leaves you in the seat of your pants, and a perma-smile from ear to ear. <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/smile.gif" border="0" valign="absmiddle" alt=':)'>

I dont know what it is but i have felt that same feeling around 5.5 I can't really say it feels like vtec cause i never drove a vtec car. But i do feel a boost around that rpm

Its the KA's last effort at pulling hard, cause right after that it just gives up.  Power right after that point falls off quickly.  

Between the tip in retard, clutch fan disengagement, and the power surge at ~5k, and falloff after 6, this engine has way too many personalities within its rev range.
