08ish civic si vs 02 z28

**Too Fast** · 11-30-2010, 02:32 AM

I can rarely give props to the sound of a 4 cyl. engine, but it happens sometimes, like a real, high output engine like on a motorcycle, not something relatively stock with a fart can.

**02sunsetorangeZ** · 11-30-2010, 04:40 AM

yea for sure, not too often at all you hear a nice one.

**slpdablueZ28** · 11-30-2010, 02:13 PM

you think it would be possible to lsx power a golf cart? that thing would have such a great power to weight ratio

**Too Fast** · 11-30-2010, 02:19 PM

^^^Hey Dodge did it with a V10 powered motorcycle, so why not? But we are off topic.

The new civics are over 3klbs and are still FWD. A rx7 or 240sx is around 2700lbs so either of those are a much better choice.

Lol, having previously been involved in the import scene, I can enlighten you on these mysteries!

First, every modded import owner will respond with "intake and exhaust" when asked what he has done to his car. i guess everything else is considered some kind of secret, lol. As for what mods he actually had, I won't speculate on that - there are tons of options, forced induction or N/A. I will guarantee that if you didnt pull him hard with a 12 sec Camaro, he definitely had more than an intake and exhaust.

The blued exhaust tips come that way from the manufacturer on most aftermarket exhausts with titanium tips, makes it look good, but definitely doesn't mean he was running alc/meth. That's pretty rare - but blued exhaust tips are very common.

And the mysterious black puff accompanied by the change in exhaust tone is the good one. What you witnessed on that day was the engaging of VTEC. Somehow, Variable Valve Timing and Lift Electronic Control, became VTEC. I guess "VVTLEC" doesn't exactly 'roll off the tongue' in quite the same fashion. Anyway - at a certain rpm, usually around 4800-ish, the VTEC engages the secondary (read: larger) lobes on the cams to increase high rpm performance. This results in the normally docile-sounding 4-banger actually sounding kinda mean, especially with a GOOD aftermarket exhaust, like one from APEXi - nice and throaty instead of typical rice. This also results in a moment of rich AFR during the transition, which is where the black puff comes from.

I know alot of ppl disagree with "honda" and "sounds mean" being in the same sentence, but hey, keep this in mind: it could be a Mazda RX-7 with open headers.. YUCK.

Well hopefully I didn't make myself look like a complete retard with my first post ever!

Now that I have shared some knowledge that no one with a V8 cares about - I look forward to learning the way of the big engines from you gentlemen. That's a fair trade, right?

Why did'nt they just use better cams?

GM quad motors made lots of power on just 2 cams and no v-tec.. Tuned and piped they can get over 200 crank N/A.. Not a fan of 4cyl tho..

Good kill op..

Imagine how much better the quad 4 woulda been with VTEC. Give it 40 more HP easy....as long as the timing chain stayed in place. Some of those HO quad 4s were 180 OE, right?

thats not too bad for a 4 banger i guess lol even though my fast and furious 98 civic dx puts down a whopping 105hp or so from the factory

Yeah ~180-190ish.. The quad motors were the forerunner to the LQ1 program and then later the northstar program. I don't think you actually need v-tec. If it were a DI motor, with better CR and a split in degrees on the cams.. But again it's a 4 banger so I'd only use it in a one man dune buggy..

thank yall! o and g2dab, welcome to the site lots of knowledge here

VVT is not a bad thing. Alot more cars have it than people think. All the brand new 2010+ ford v8s are boasting it, 5.0 stang has it, lexus isf has it, subarus have it, some supra engines had a similar system and many more. They all just call it something different.

**02sunsetorangeZ** · 12-08-2010, 05:59 AM

yea i guess chevy's type is called displacement on demand. My moms 07 avalanche goes from v8 to v4 to save some gas mileage. I guess thats kinda the same thing?

Not quite, check it out: http://world.honda.com/automobile-technology/VTEC/

The 06+ Si's weigh 2,886lbs in the coupe trim, and 2,945lbs in the sedan trim. (Not that +/- 100lbs really makes a difference on a vehicle that puts down ~180fwhp stock, when compared to something LSx powered.)

I own one of these actually. Eaton MP62 blown @ 9psi, and I'll have to say its not exactly slow. On a 9psi pulley, we've seen guys put down low 13's in the 1/4 ( edit: no links to other forums please.....0rion )
Annnnnd.... *Flame suit on* :giggle:

Nope, not the same at all. Dod shuts off cylinders making a v8 a v4. VVT makes more hp by opening valves more and at the right time to make more effecient power, DOD makes less power because your running on less cylinders but you get better mpg.

true its just like dodges MDS which is really just a gimmic to get you to buy one

we turned it off on my parents 07 charger with a hand held programer and only lost 1MPG

My friends TB with a v8 DOD has gotten 3more mpg city keeping it in DOD which requires you baby the throttle. But after two days he gave up and said he cant drive like that anymore.
