Hi everyone,

I’m looking to add more power to my Teg and I’ve considered a turbo for a while now but I never really even looked into supercharging.

Can anyone here explain what would I get with a supercharger vs turbo?
What is the cost difference between the two when all is said and done?
How is the reliability and who makes a good SC kit for the tegs?

Here is my setup:
B18C1 ~110K miles - no mechanical issues.
ITR cams
Cam gears - can't remember the brand name right now...
I/H/E
Hondata S300
Clutch, fly… some other goodies...
On my last dyno the car put 175 to the wheels, i wanna get to about 200-220.

Tell me what you think!

Thanks!

Your gonna need to do a lotta reading along with posting at the FI forum btw before you get flamed by others to tell you to search. SC's jackson racing would be the most repuatable and popular choice by most honda enthusiasts. Turbo's vary a lot, unlimited options to choose from, hence a custom turbo kit. More power obviously from a turbo, depending on the trim and size and goal of HP. You'll spend nearly the same amount for either one, but a bit cheaper piecing together a kit yourself and save $$. SC's might have to purchase as a complete kit, never really heard people piecing together a customer SC kit, correct me if im wrong anyone. SC's don't suffer from lag, so power is through the entire powerband, SC's aren't as upgradeable as turbo, you can upgrade the pulley to a certain size not sure how many there is, but it is converted to amount of PSI it will produce. Much more reliable since it doesn't used forced air unlike turbo, and doesnt heat up the motor as much as a turbo. For turbo's you have room to grow incase you want more HP which you will want for sure. With a boost controller, fuel upgrades and a tune, you can easily adjust the amount of PSI which will then produce more power. HP is easier to attain with turbo, produces nearly twice as much HP as the SC. Reliability wise is slighty less, but not by much, but with a great tune which is most crucial and quality parts, you car will run forever with proper maintanenance of course with either system. Turbo's do heat up the motor which will decrease the life of the motor over time, but again it all depends on the turbo your using, the tune, and the engine parts being used to support the turbo. So now it all depends if you have the funds to make this all happen. For that low of HP, I suggest going with a custom turbo kit using the small T25 turbo from a mitsubishi eclipse, and with supporting mods and a good tune, you should be hitting the 200-220whp or more if you up the boost. Do a leak down and compression test, replace any or all parts that are due for maintenance. Then you should be all set anyone else that I miss please add to it. GL!

I know, but info I found wasn't all in the same place, it's scattered all over... And my PC got fried so I'm posting from work very quick while trying to avoid getting caught by Lumbergh! I'll look more though.

I did look into piecing together a turbo once, a T28 or a K4. I know the HP would definitely be higher wioth turbo but at this point I'm leaning more towards reliability. I'd definitely wanna do a full rebuild because turbo shouldn't go anywhere near a stock bottom end with 110K miles on it (IMO).

I've heard from many that SC goes well with the high compression of the GSR and ITR, much like it does with the NSX. I'd have to get new GSR cams to go turbo.

n/a cams work well with turbo from what I've read compared to aftermarket cams due to the size of the lobes on the cams. Can't explain further on that part, but read enough about awhile back. If your goals are just between 200-220 the T25 I mentioned earlier will be great for your setup, 200-220 is not much HP anyway, a built n/a motor can hit those numbers. Just make sure your running low boost with that turbo or run at a psi that produces those numbers. If your pushing out 175whp already, boosting around 6-8psi should easily get you 200+, with stock reliability and internals. Many honda drivers here are successfully boosting way past the 100k mark on their motors.

The guy in Denver who sold me the motor (who also worked on my car all the time) said that if I go turbo I'd need to take out the ITR cams and put the GSR ones back in. He said it's not that they wouldn't perform, it's just that with the ITR cams the turbo wouldn't perform as good.

ITR cams will always make more power than GSR cams. If you had adjustable cam gears and dialed out some of the overlap in the ITR cams, they would perform really well; more so on a well flowing turbo manifold setup.

 

turbo over sc anyday. for the same cost you make more power and it's just as reliable.

 

Have you considered upgrading your cams and valve train. This with a good
header and tuning may get you close to your taget HP plus the benefits of long
engine life and driveability. Good luck!

 

i have a jackson racing s..c on my tegra.. i enjoy it.. it makes for a good daily driver... when it drives...

 

Nice write up. Roots type superchargers like the Jackson kit do not experience any lag, but other centrifugals(Vortech) do. Yes, turbos do increase heat. But if they decreased the life of an engine, I assure you Honda wouldn't be using a turbo charged engine in their new RDX or any other car manufacturer that turbocharges their vehicles from the factory. It's the fools that think they can run 21+ lbs. of boost without any tuning that decrease the life of their engine. Google "volumetric efficiency turbo" for more info.

 

really its up to you and what you do with your car. i have a JRSC gsr and love it because of the instant boost. i just push the gas in and it goes from vacum to boost at any rpm &gt;2k. the problem with the kit is the intorcooler is so expensive. if you run 6psi wou will be safe with out it but you will see 150 degree intake temperatures. you can intercool a turbo setup cheaper and get more power out of the same 6psi of boost.

so if you dont mind lag or can brake boost then turbo is for you. if you need instant boost ie: auto-x then supercharger will be better.

 

put it this way, say if you got a gsr motor, and have $7,000 to play with, $7,000 on a turbo kit, installed and tuned will make 2x or more power then 7 grand on an s/c, installed and tuned. You have unlimited options on the size of the turbo to go with and you might even have money left over from the turbo kit. Imagine putting a GT35 turbo on it and gaining over 350+whp w/supporting mods and boosting around 12+psi, compared to a jsrc that does around 260+whp with same psi and same supporting mods with same amount of money ($7,000) you decide.

 

I personally drive a SC'd GSR and I feel confident that if I had 7 grand to begin my SC build my peak power would be 300+. But IMO peak HP isnt the end all but one should consider the whole power band itself. Feel free to search my setup I have my dyno charts posted in one of the threads. Whatever you decide just make sure its because thats what you want to do and not just what people are telling you to do.

I can only imagine having instant boost . Similar to when I drive my brother's corvette c6, v8 powered 400hp monster. Gives me the chills when I launch :

 

I was mostly interested in SC because it would be something new to me, I've driven turbo-ed cars before but not SC, at least not on a SC four-banger.
But I'm not really planning on spending 7K either, for a little more than that I could boost the NSX.
I just want a fun daily driver car and frankly, I thought for some reason that the SC would be cheaper and more reliable, even though less power.
