"dual vtec" "3 stage vtec" please share what you know!

Thanks for the info. I like to keep my options open for when my insight needs an engine or I just want MORE POWER.

FYI, since you got the psi sensor in the vtec thingie if the screen is clogged or you have internal damage that lowered your oil psi when its time for vtec 1,2,3 to engage you will just get an vtec error and it wont engage as that will further lower your oil psi.

cool, glad to share- I'm proud of my Minion

re: the vtec oil pressure sensor- that is not used in my application (I believe that's because the dual vtec system is rpm/load based in it's delivery, and not dependent on oil pressure) I know the vtec pressure sensor is used on the other vtec's, but for some reason, not mine

I'm still learning about it, but this is the best economy / power setup yet! My buddy here is trying to get me to the track in the minion (he's a mopar musclehead, and my mechanical YODA), but I keep putting him off. This thread has got me thinking maybe I should go The cool air might help with the go-fast!

thanks,

From what you are saying it almost sounds like you dont need a civic si for power, but the right engine and cpu. Sometimes 88 hp and 88tq dont cut it and Id love a vtec that can throw you back in the seat for merging, then back to eco mode. No oil psi sensor? Sounds like a great way to send your pistons through your hood.

haha! I sure hope not!

I will tell you, though if for any reason the rpm's (and oil pressure, I'm sure) drop below about 650rpm or so, I do get an oil light on the dash.

Actually, I just got that (oil light) yesterday in the morning on a cold start. she was kinda poopin' and running like it was starved for air or something, and I remembered my "yoda'" telling me that for every 10 degrees the temp goes up or down, I'll likely have to adjust the air mixing screw at the throttle body (since I don't have idle air control) we have been talking about making an adapter to get my 3 wire iac to acutally control the idle, but that's for another thread..

(power is 128 P.S. -jap rating- about 118 H.P. on the "wild cam") - more than enough for a good time! But, as you can see to the left, It doesn't see much action.

thanks,
victor

This is a link to a pull in a tunnel coming back from PA, Where I met fellow ecomodder SLOWNUGLY



rolling start, prolly 30-40mph. dropped to 2nd gear for the pull. full throttle, wild cam hits at about 14.5 seconds in. It sounds cool, but I had lots of tools (900 mile trip), a copilot (200lb "yoda"), and I had my trunk full with a D15Z1 AND VX TRANNY!!!



Did I mention the 3" stainless ebay exhaust? sounds better than the phone can record, I promise

{ugh, I just watched it on youtube, and you can't hear it as well as you can on my phone}

Sounds like you start to lean out at 17 seconds. Cant hear vtec kickin it yo.

[vrmouseyd15b]

Yeah, it's way more pronounced in first gear. I'll have to do one with my dash cam sometime soon

How do you tell if the parts are interchangeable? I like to entertain the idea of putting the crz 16v head on the insight 8v engine. We got 2 spark plugs, but 1 is primary, other secondary so we could loose the right side plug I believe. If the head fits, hope vtec works the same so its a direct replacement.

Plan B is to swap in the whole crz engine. Its a 1.5 vs 1.3. From my experience the Insight uses a lot from the 09 Fit.

[vrmouseyd15b]

not sure how to tell if parts are interchangeable.

wow! is that 2 plugs per cylinder? that's one way to adjust timing for lean burn!

is the insight/fit motor still a "d" series motor? I know you can make some pretty wild combinations between all the "d" series stuff. that would be wild if you put one into an insight!
