i may have just opened a huge can of ****, but tell me what you guys think?
btw if it helps whats your opion of these on 06-07 civic si's

 

depends on what you plan for your civic.

if it's a DD: Supercharge

if not: Turbo.

can't really do **** right now since there isn't a fuel tuning program out right now.

 

We own a 00 Si turbocharged & intercooled, all GReddy. We researched this deeply when we decided about 3 years ago with what to go with. The turbo, even though it has a slight lag, seemed to be "free horsepower" because of how it works. The supercharger is more immediate, but pulls power. The turbo was really easy to install and with GReddy's reputation, everything fit perfect w/no mods at all to the car! Did this help any?

 

I don't get why everyone and their mother says "S/C for a DD, turbo for a track."

If anything, it should be the opposite. With a turbo, you can keep the turbo from spooling up by keeping the RPMs low. So drive civilized during daily driving and you will stay out of boost. With a S/C, you're always in boost. Not sure if that's such a good thing.

Not only that, but turbo's just net more power. Especially on a 4-cyl, they just work better turbo'd rather than S/c'd.

 

If it were my brand new car i would S/C it so its undoable incase something bad happens and it needs to go to honda.

+1 I've owned several turbo Hondas now and the only people who likes to post their "wisdom" on FI are also the ones who have never owned a turbo Honda. Nothing against SC's, I'm into turbos for the fact that I'm more experienced with them. Like Elehol stated, stay off the throttle and the boost never kicks in.

This is exactly what I mean.... Have you ever installed a turbo before? It's all bolt on parts and can be taken off! Only thing is getting a plug for the oil return on the oil pan.

And to the OP this has been covered in every single forum out there, it's a debate with no end. Some people believe in SC, some Turbo. As far as it goes for the Si, I'm all for any type of boost for our FGs.

 

i should have stated it better..my post kind of seemed like the usual automated response when this topic comes to debate.

i'm pretty sure the OP doesn't plan on pushing turbo'd 300+whp civic 50-100 miles daily through traffic.

then again, if he's looking for something around the 250 range and driveable every day then i would supercharge it. just my two cents.

+1 i agree with this totally. turbo you make power with waste. With s/c you waste power... well not really but your motor has to work to make the power. if you get what i mean. but its really personal preference. ive never ridin in a s/c honda but turbo ones are fun as hell.

x2. If I turbocharged my daily driver, i'd size the turbo big enough for full boost to come in above 4k. I could manage to get some decent fuel economy but still have fun if I wanted to.

I'd rep you but I can't.

BTW....going to the HT meet on Sunday?

 

personally i agree with gettin turbo
the reason is clear
if you want power all the time then SC is the way to go
but turbo is fun and yet DD friendly
so it makes sense to me . . . . .

exactly....S/C is more out of the hole..so therefore..since a 1/4 mile is not long at all...you need all that power thru all those power bands with no lag...and turbo...you just get to higher mph faster. more highway fun and DD. maitenance is required..but its simple. it'll be a regular thing.

 

thanks for the input guys
ill probably end up getting turbo since it will be an everyday car
and since i can probably install the turbo easier and get it for cheaper :D
btw does anyone know exactly what rpm the turbo kicks in??

That all depends on your engine and the turbo.

A turbo works on airflow- exhaust gases spin the turbine up to speed to make power. If you put a big turbo on a little motor, you won't make power until the peak of your power band. If you put a little turbo on a big motor, you'll restrict airflow, it will make peak power way too early and then will actually hurt engine performance.

You need to either find someone experienced or get a kit with a well suited turbo in place. I would personally find a turbo that would hit full boost around 4500 rpm because you can stay under 3k driving normally and save gas, but you can open it up when you want.

 

all motor

 

supercharger on one side and turbo on the other!

Actually, a s/c is not always in boost.

 

No matter what you get, there's always going to be a group of people who have a negative opinion about it, just go with what you feel will be good for you.

I know someone who has the Comptech S/C and IMO is all I would need personally. But that's just me and everyone has their own unique wants and needs.

You may want to get a hold of someone who has either one of these kits installed in their Si and go along for a ride to make your decision because reading forum opinions is just going to make you nuts.

 

thats what made me decide really... i had a turbo honda and it was fast. but i like the power off the line of the S/C so thats my choice for this car. I dont plan on doing many 1320s honestly lol. but road america is right by my parents house and it would be nice to get some laps in there.

 

i was thinking of getting the greddy turbo kit
im not sure about the specifics of it but, i would just buy stage 1 stuff and see how that works with the engine and i was also think about an ecu flash :D

I was waiting for someone to correct that.

How is it not always boosting? I'm not gonna pretend to be any sort of car expert in the least, but doesn't a supercharger run off the engine, so when the engine is running, the supercharger is producing boost?

 

The s/c still builds boost...I do not really know a good way of explaining it. If your not pegging/flooring it it really doesnt come on.

I could drive very normal (shifting at like 2200 rpms) in my 93 si hatch with the JRSC and never hit boost. On the roots type blowers there is a valve much like a Blow off too....just another thing that most do not know too. I believe the valve stays open releasing the boost until the throttle is pushed enough.

 

This information is great!! I just got an 07 Civic Si and I have been wondering which is more practical in nature. The Turbo seems to fit the bill; now the question is finding a turbo that is both good and reasonably prices for an 07. Till I come up with the cash I'm going with a CAI with by-pass filter for water problems; thus far a AEM with it's patented air by-pass filter is what I have planned. Supposedly the by-pass only works with AEM products. I hope I at least get 7 - 8 more horsepower and a little bit more lbs per foot.

Does the turbo kit come with everything you need so that you won't drive to hot? Or will I need to buy exhaust compensations as time goes by? I don't know if it's true and the Honda website sure doesn't have any answers, but I have read on-line that the 07 Civic Si already comes with some minor tweaks short of a Turbo (they really should offer that option on them; natural air intakes make no sense at all). Opinions?

 

Its very simple. Its been stated before.

Supercharger = More reliable, easier to take off, easier to put on, less power.

Turbocharger = More problems, harder to install, harder to take off, MORE power, and MORE power potential.

Tuning is also a lot more important with a turbo car than a super car. You have a lot less margin for error.

So for me lets face it. You will never have the fastest car on the road, and theres no point in going all out trying to make your car the fastest it can possibly be. Just make it fast enough for you. Which is why I would choose the S/C route. Turbo definately makes more power, and is definately "cooler" perspectively, but there will always be that one guy that owns a speed shop with a turbo b16 hatch that can run 10's on street tires (my friend found that out the hard way last night)

And there will always be the rich mothers that own Z06's, M5's, M6's, Gallardo's, Vipers, ect.

Supercharger FTW!
