Civic 1.8L iVTEC chart

GlennS · 06-01-2006, 12:12 PM

A visual from www.japanesecarfans.com / www.worldcarfans.com showing when iVTEC in the 1.8L engine kicks in is HERE.

Update: VTEC as implimented in the R18 is actually sorta "backwards" from that of the K20Z. That is, the R18 is in VTEC at low loads, and kicks out of it under higher loads.

Don't take my word for it though, see:
Asian 8G Civic R18A Engine Tech Overview

cool thanks for the info

GlennS · 06-01-2006, 01:08 PM

Looks like their site went down right after I posted the link. It's not a perfect world, so just give it some time and I'm sure the site will come back on line. <edit> There, the site is back up now. All set. -Glenn

CHRIS · 06-01-2006, 01:13 PM

damn that site is awesome, i didnt even know about some of those honda cars...+1

Cool stuff !

8thgenuser · 06-01-2006, 03:04 PM

Awesome...thanks for the link! Those are some great cars on there.

I'm driving thru the twisties this weekend. I'll be sure to keep the revs above 3,500 rpm!

Since I'm new to V-TEC, I'm trying to figure this "fuel economy cam" and "high output cam" thing. Since 1.8s only have one cam, how does it "kick in"? Are the lobes on it different at different places for what it needs to do based on load, acceleration, etc.?

That link will take you to a Civic section. Scroll down to the bottom of the page. There yopu will find more specs on the 1.8, the chart posted here and a video highlighting the r1.8's tech. I think Honda posted this in july of 05.

Here's a movie from that site on the 1.8L engine. It makes me so proud of my R18.

CivNick · 06-01-2006, 11:32 PM

so the faster i drive the more gas i will save?

SiGTi · 06-02-2006, 01:08 AM

umm, no.

keep it under 3500 rpm because thats when the motor tries to limit pumping losses. less power, but more economy

"The R18 is leading the class in I-VTEC technology"

makes me afraid to modify the damn thing lol

The Honda "movie" others referred to is excellent.

Here's the concept put another way (credit to www.japanesecarfans.com)...

Can someone sticky this?

GlennS · 07-25-2006, 12:49 PM

Honda has a video on the Web showing the internal operation of the new 1.8L iVTEC as in the 2006 (non-Si) Civics, here:

How iVTEC works in the R18 motor
Click on the "Watch the movie" link on the right side of the press release.

hoanger · 09-21-2006, 08:42 PM

I, for one have never hit VTEC in our R18's... maybe I don't know how or I'm supposed to be doign something in particular... maybe someone could tell me how LOL
i'm pretty anal about going over 3k RPM's in any gear unless the person in front of me is driving insanely slow and accelerating at a ridiculously slow rate then i gotta bring it up momentarily. maybe thats why i haven't gotten it..

civic_dx-g · 09-25-2006, 05:02 PM

seems pretty simple, VTEC kicks in at 3500 rpm, you drive below 3000 rpm... which part of this is unclear?
