SI vs sligtly modified non-SI

Apex77 · 01-25-2006, 09:44 AM

How much will it cost and what after-market parts are needed to boost the HP of the non-SI models to the 170-200 HP range ?

Also, what will be the effect on fuel efficiency? Roughly how much will the mpg drop?

I am trying to get a rough idea to see if it will be more economical to get a non-si civic and modify it slightly. Perhaps an LX.

Items of concern:
1. Cost
2. Will warranty be affected
3. What will be the impact on fuel efficiency.
4. Performance gain

Maybe someone has a vague or precise idea ....

No. You can get an Si for the same price as an EX.

Just get an Si and be done with it. To get a boost from 140 to 200 hp will require forced induction or SERIOUS N/A mods... I/H/E bolt ons will not get you close. Theoretically, exhaust systems help with gas mileage, but usually those with exhaust like to hear themself rev it, therefore, worse gas mileage.

Keep some dignity, if you want a fast car, buy a fast car... the Si. If you wanna be a rice boy and make an economy engine sound and look "fast", well, let's just say you're APC's prime demographic:rolleyes:

Sorry to sound so harsh, but there's no point in getting an $18,000 car then dumping $5,000 into it to get it on par with the Si. In the end you’ll spend more beefing up an LX than you would’ve on a straight from factory Si.

Thats pretty much what I figured. By the time you soup it up, you would have spent more.

I'll keep dreaming for the low cost (under $20k), high HP (170-200), and high mpg car.

Check into the Subaru Impreza 2.5i. It’s got 173hp and AWD and can be had for as low as $18,500 pretty loaded. No, they’re not the best in gas mileage, but neither is the Si. PLUS, the Si requires premium fuel.

Another consideration is the Nissan SE-R Spec V. 175 horsies and pretty strong performance all around... also about $18,500.

They’re out there… quit dreaming, start looking

schnellsy · 01-25-2006, 02:30 PM

Yeah I'm interested in checking out the Impreza 2.5i too.

jandree22 · 01-25-2006, 02:35 PM

That's what I'll probably buy this summer over the Civic... a 2.5i Wagon

More horses, AWD, Wagon available, same impeccable reliability, same price as a non-Navi EX.

Civic wins in gas mileage and innovations(digital spedo, navigation, etc)

Endorsing a non-Honda on a pro-honda site ?? :)

jandree22 · 01-25-2006, 03:29 PM

So far (knock-on-wood), this site has been friendly with that stuff. So long as an individual doesn't go out of their way to trash talk Honda or the Civic, that is

In the end, all that's important is that everyone gets a car to suit their needs.

I wouldn't necessarily say the reliability is the "same" but if you're going to buy an Impreza, just wait til the end of this year. They're supposed to bring out a new version (not just a redesign like the 06...that was pretty pointless:rolleyes: )

That goes beyond funny and lands in the "sad but true" field. My uncle used to be the head sales manager for APC, and he said that that was EXACTLY what his customers acted like.

Grab an Si and love it. The aftermarket industry is going to cater to the Si way more than the base models anyways.

Actually, according to a 2005 Auto reliability report released by Consumer Reports, this is what they had to say of the small car segment...

Toyota, along with its Lexus division, makes more than half of the sedans and small cars that earned our highest Reliability Rating. All the others that earned this Rating were also Japanese, including the Honda Accord and previous-generation Civic; the 2006 Infiniti M35/M45; and nonturbo models of the Subaru Impreza.

Most of the worst sedans in our rankings came from Europe, including several expensive luxury models such as the Audi A8, BMW 7 Series, Jaguar S-Type, and the Mercedes-Benz E- and S-Class. The rest of the bottom-rated small cars and sedans were from domestic manufacturers and included the Chevrolet Cobalt, the V8-powered Chrysler 300C, and the Lincoln LS.

Also, I've read several reports of Impreza owners keepin their cars for as high as 400k miles. I'm not saying Honda went to crap or that Subaru should be bowed down to... but IMO, at least both being pretty close? Definately.

The 06 change added features such as projection headlights and a few horses to both the 2.5 and WRX engines(the WRX went from a 2.0 to a 2.5). Those changes have a point.

As far as the 07 redesign, more indications point to a 08MY change. And I do NOT want that change because rumors are that it will be based on a modified Legacy platform and it will be made in America, not Japan. Even worse, rumors point that it's going to lose the Impreza name and be replaced with this... the B5 Hybrid concept

I would laugh at your suggestion, but then Chrysler went and replaced the Neon with the Calibre.

Yeah... the B5 thing is like a 50/50 shot in my eyes. They released the ugly ass B9, and Subaru of late is meshing their vehicles together more in a corporate styling scheme... as seen by the grill of the 06 Impreza matching the B9. Who knows, maybe they'lll unveil the B5 tomorrow going on sale this July. Whatev...

Back to the Si, sorry, didn't mean to jack the thread

***Celcius*** · 01-26-2006, 05:31 PM

Whoa, whoa, whoa. Before we move back to the Si, I have to know - is that monsterous thing supposed to be the bastard child of a coupe that got raped by an SUV or what?

jandree22 · 01-26-2006, 06:23 PM

haha, that my friend, is the potential fate of the WRX. It's not some whack magazine story either... there's a good bit of umph behind this rumor. The concept is real, it's a Subaru B5... uses some kind of hybrid technology. Whether or not this is the answer to the Impreza in '08, that remains to be seen... like I said, IMO, 50/50 chance on that. Regardless, here's a link to more pics... not for the faint of heart!

(In its defense, that pearl color is the WORST... give it some flashy blue, red or black and it might look a whole lot different!)

CuRiOuSfIsH · 01-26-2006, 08:15 PM

the current Impreza is good, especially the WRX.... I suspect the turbo 2.5 is actually under rated....
now, the main questions:
1. I/H/E pending they are all brand name, should run $800-$1000
2. if you want Si power in R18, of course it will void warranty no doubt abotu that.
3. ???
4. As of now, not many things you can do.... but I/H/E would perhaps net you 10WHP. K20 I would think dynoes at 160-165WHP.... R18 5 speed dynoes at around 120WHP.... 40WHP gain would come as mentioned above, turbo or some serious and many NA mods.
in other words, get an Si if you want that speed.
