How many get Vtec and Redline their engines everytime they drive them??? Is it and engine and ring thing?? ( a ? for the technocratcs ) Is that makes them last??? I have DD 94 civic pushing 400 k and have pushed it hard since 1996, will my S2K do this too ???

Wow, spelling man. I vtec a lot everyday, but I usually shift under 8000 unless need be.

Yeah, slow down when you type or something. Read it back before clicking "post", etc. Or not...whatever.

Anyway, drive the car however you'd like, redline all day long or once a month. It'll take it either way. Just follow maintenance and you'll be .

For me, I'm kinda "all or nothing" with it. I either drive completely normal and shift 4-5 or whatever, or go balls out to 9K. I rarely shift at 6500, for example. The nature of the motor asks for that, but again, that's just me. Whatever makes you smile.

for me its different... i have a f22c swapped into my ap1 sometimes i shift at 8k and sometimes 8.5k... and 9k.. either way it pulls hard when i rev it pass 8

using an ap1 ecu with ap2 motor?

My concern is whether the VTEC can get 'stuck' if not used for a period of time. Recent medical problems have limited my usage of the S2000. Much of the time I am involved in 'around town' type driving. I try to make sure that I can hit VTEC rpm at least every couple of weeks. I find myself wondering if the solenoid can stick if not engaged for a period of months, or, worse yet, if the little oil passages which engage the high rpm cam follower can collect clogging deposits. I have never had any VTEC problems, even though my total usage is never for more than a couple of seconds at a time, and sometimes only once or twice a month. Any thoughts among fellow s2ki members???

It'll be fine, I assure you. Can you imagine if Honda produced an engine that was as fussy as that? Rev higher when you want more power, just like any motor. This fuss over VTEC needs to stop.

It is certainly true, however, that an engine ages better when it's used regularly as it's meant to be, rather than sitting and collecting dust. This avoids hoses and whatnot drying out and cracking, fluid problems, etc., among other things.

I have no doubts about Honda engine reliability versus time near redline. I had a '95 Integra GSR that spent a lot of life near its 8K redline and bouncing off the limiter. Only its OEM mini-header (B-pipe) ever needed replacement and that was done under warranty. When I got rid of it, after 80K miles of hard driving, that motor still ran like a Swiss watch.

I would worry more about a motor (heh, and driver) that never activated VTEC for thousands of miles. Valves need to be exercised. Seals need to stay wetted.

If you drive your engine like a grandma for years and then you decide to redline it, you can run into some problems.

When you rip the engine to 9000rpm, the rods get stretched every so slightly more than if you shift at 3000rpm, due to the extreme forces. This pushes the piston rings ever so slightly higher, creating an ever so slightly longer wear pattern on the cylinders. If you've been shifting at 3000 for the past few years, and one day decide to rip it to 9000...the piston rings might encounter a "step" in the wear pattern on the cylinders...possibly breaking them.

This is why it's advisable to shift at redline as often as possible.

i still havent hit vtec or redline and its been a little more than 2 weeks. :]
