I am looking to go forced induction on my '03 type s but can't decide weither to go Turbo or Supercharger. I have already decided I am going to upgrade the valve train, and break down the engine and check the rest of the internals for wear and a full exhaust will complement either one. This is still going to be my daily driver for a little while but it will also be a weekend warrior for cuircit and autocross. Either way it will also have a k-pro doing all of the thinking for it. I am looking for input from people who have or know people that have a turbo or supercharger installed already and how they like it plus the pros and cons.

Daily Driver, Circuit and Autocross = Supercharger

Smooth linear powerband and almost instaneous throttle response. Turbo is going to have lag even with a properly sized turbo. The small *** Greddy turbo that can barely break 300hp still has some lag. The supercharger is capable of over 10 psi and will complement your daily driver and autocross car perfectly IMO.

Turbo is not for everybody and it seems your more interested in autocross than big numbers and the 1320.

Wow this has been beaten to death sooooo many times.

S/C is perfect for daily driving. It has a linear power curve etc.

Turbo can be good daily driven also. Power comes on as a sudden surge usually unless its a very small turbo.

DO a little research.

I have been in a bunch of fi Honda's and with out a doubt I would prefer supercharging for a DD. As posted above a well tuned supercharger will give you reliable, linear, quiet, usable horsepower. If you had a dedicated track car or wanted to make a dyno queen, you may want to consider a turbo, but if you have to drive this car everyday, then supercharging is the way to go.

I have done the research and I know what the difference is in numbers. I'm looking for input from experience which can be 2 different things.

Well it looks like Supercharger is the way to go. Thank you for the input confirming my doubts about which one to use. If anybody has one installed or knows someone could you drop some input as far as mantinence and easyness to work on. Also things like installation time and difficulty.

I have had a JRSC on a Honda..... no maintenance at all..... cant say about time to install, I pulled my motor completely out and did timing belt and waterpump, and a few other things. But I had all that done in about 12 hrs.

besides replacing a belt i've had no issues with my ctsc

Dont supercharge a 4 cyclinder caR. Your going to want more power, and the supercharger isnt going to give you the more power you want. The same psi on a turbo gives more power then it would on a supercharger. Supercharger belongs on 6 cylinders and up, where they can afford to loose a little bite of power...

Jackson racing claims that with there set up and a k-pro that the RSX S can make 250 Hp to the wheels which is plenty for my purposes. I do know a guy with a turbo with the "more power" that you're talking about and he doesn't have traction untill 3rd gear. After all of the posts it sounds like a SC is for me.

P.S. They claim 280 with a pulley upgrade. Some times it's not about maximum power but about the optimal power for the entire set up.

go turbo and get K-Pro.

But Turbo creates more heat and lags no matter what. I want instant power with out baking my engine compartment and I really don't feel like putting in an intercooler.

I've got a turbo dc5 and I can tell you its fantastic. I love it and its potential.

Now I can also tell you I hate it. One loose screw will kill your weekend trying to find out why you're not boosting. Plus just the inherent issues of boosting your car. It's great in a line, but doesn't give much to turns and such. Uphill is a fun run now though.

Would I do it again? Boost, yes, turbo.. probably not. I'm not after big power though. I just more power. So I would probably go with Comptech SC. It's one brand the dealer will install and actually ads value to the car since you can buy it from some dealers too. ... I'd probably try and prototype a bigger pulley or something, but still But damn I'd miss the sound of spooling up a turbo...

i am selling my JR supercharger setup (race version) if you are interested. comes with everything but injectors.

John_DC5

Does anyone know if a supercharger came out for the 02 base rsx yet???

moores55

I have run all of them (n2o, supercharger, turbo) and i have to say the turbo rought is the only way to go.

Axix24

just depending what your goal is and what your using your car for...

DaveSi677

wow where have you been hiding??? lol

Turbo FTW

Superchargers are slightly easier to install...not as much labor...but you'll likely never be satisfied with the power they give you...sure they will basically give you instant boost but they aren't as efficient and they don't have nearly the potential as you would get if you turbo it...build the motor to your fancy, turbo it, and make sure to get Kpro...can't go wrong with that...just my opinion.

vladd

the supercharger would actually create more heat. after a certain point upping the psi on a supercharger doesn't create any more power because of the additional heat, while on a turbo you can keep upping the psi until your engine blows up .

edit: just wana say that i'm talking about intake air temperature, not the underhood temp. with either one underhood temps shouldn't be high enough to damage anything unless you're running like 800 hp.

right now i'm running a jrsc on my 98 gsr. And i've had no problems whatsoever, running 8psi. So i'm upgrading to a 3.8 nos pulley, a b20 crank pulley, changin the belts, rc440 injectors. Tuned to hondata s300. From there gonna call up motovations motorsports, and get there stepper pulley. Finally goin for the Lht intercooler. It's foolproof. I can drive it around and take deliveries at work durring the week. And rapin some douchers and there beater civics on the weekends. I'ld say for what i'm goin for definitaly go supercharged.
But runnin high boost (11-12 or more ) you must cool the engine or you'll be shootin flames from the exhaust.

Lht makes an intercooler it's over $1000 and if you don't live in florida you have to send your sc to them and they'll do their stuff lowering engine temps up to 100+ plus degrees while knockin up the hp by almost 30.

Option 2: you can go water/methanol injection. I don't know much about it, but i've heard it's mainly for turbos so don't quote me it is an option though.

option 3:nitrous oxide. You can run a wet shot through the blower maybe a 75 shot something like that. But i have heard that it breaks down the fan and really f**cks that up. If thats the case go direct port i've heard it better distributes the shot to all 4 cylinders.

But in my personal advice i say go ***** out have lht fix ya up and get it intercooled, then from there, a zex wet 75 shot. Direct port. Get a good tune hondata (s300) reccomended. And tune it so the Nitrous will shoot at a certain RPM. Now i'm not sure the full hp level with a setup as such but i'm guessing (don't quote) 350-400 hp. kinda off topic but that's the way to go if you want a supercharger. If your goin turbo i'm not the guy to ask.

Besides do your own damn research

Curiouz_G

if your aiming for about 280whp, swap a k24 in there and go with a light NA build. N/A > FI for instantaneous response

Read through the FI FAQ. It will answer this question for you. If you're not satisfied with the advice in the FAQ, ask this in the Forced Induction forum...
