I was just curious cause I sold my 08 si to get my 00 s2k with 53k miles.the only difference I see is that when the s2k v tec engages it is more fierce.sorry for any mistakes I am Greek I moved to USA 2 years ago.

 

I kinda know, but I'd hate to open my mouth and make myself look dumb trying to explain it. LOL

other than that... AWESOME TRADE

 

Ivtec: Valve lift and duration are still limited to distinct low- and high-RPM profiles, but the intake camshaft is now capable of advancing between 25 and 50 degrees (depending upon engine configuration) during operation. Phase changes are implemented by a computer controlled, oil driven adjustable cam gear. Phasing is determined by a combination of engine load and rpm, ranging from fully retarded at idle to somewhat advanced at full throttle and low RPM. The effect is further optimization of torque output, especially at low and midrange RPM.

 

^ what he said.

lol closet geek.I was lmao when I was reading the what he said comment.

 

ohh thanks about your help guys.

 

can we get an easy answer? does it give you more power? make your car go faster? more with less?

I-VTEC - It's like having VTEC in variable stages - a little VTEC at low RPM's and a lot of VTEC at high RPM's. Can't do that with regular VTEC, it's either completely off at low RPM's or completely on at high RPM's. If you tried to add a lot of VTEC at low RPM's you'll lose power.

With regular VTEC you only see the benefits at high RPM's. With I-VTEC you see benefits thru the whole RPM range.

It gets more technical than that but that's it in a nutshell.
