I know this has been asked and talked about many times, but I just need clarification on what I should do.. I was talking to my friend and I came to the conclusion that a Turbo on my 97 base lude would be too much maintenance for me.. My friend has an ITR and he has a turbo setup and he keeps on telling me to go turbo.. I want forced induction but I dont want to deal with the headaches that a turbo can bring.. I think I've decided to supercharge it, but I'm not sure yet, what are your guys feelings on superchargers? good or bad idea?? Thanks for the insight

 

Turbos require maintainance and so do superchargers. But of course, it requires less for the superchargers. Both will require good tuning and if you wanna up the boost you'll have to build the bottom end due to the weak ringlands of the H-series.

 

you get more for your money with a turbo but you do need to renforce your engine if your gonna run high boost

 

I've had both the JRSC kit and a turbo on my car...

The supercharger used in the JRSC kit is internally lubricated, so the only maintenance needed is the occasional swapping of belts for the supercharger. The Prelude kit uses two belts, a drive belt, and a small short belt on the nose of the supercharger. The small belt is the only belt you will ever have to replace. It only takes about 10 minutes to swap the belt, and it one does break, your car will operate fine without it, you just won't have boost.

 

one thing I always noticed was that alot of people that use the jrsc can only run 6psi. things that kill turbo cars are boost spikes and bad tuning. turbo's are better in the respect that its not always spooled and forcing air down your motors throat. Also I've heard you have to replace a bearing every 20k somethin miles because the jrsc belt pulls up on one of cranks its attached too. if your worried about spool then get a little 18g greddy kit. you'll get 200ft lbs of torque at 3k rpms

also alot of people that run superchargers run them because they are affraid of turbo's and they are more cautious under boost. you'll notice alot of people that have superchargers run a j&s safegaurd and they tune the hell out of there cars.
^^ just an observation

 

1. How much money do you have to spend on this project ?
2. What is your goal in terms of HP?

 

Just put a 50 shot on it. many people have ran on the bottle for years and never had problems with nos on the h22. i have heard of a lot of people blowin thier h22s up cuz of turbo. since the h22 is a high compression engine. you could put the turbo on but you should think about doin forged internals as well.

 

^^ people that blow there h22 turbos either had

a.) a tired motor with already low compression
b.) failed to tune it properly and leaned out or detonated
c.) failed to install the kit properly and a mechanical failure occured
or
d.) got shitty parts (ssautochrome tial STYLE) and spiked or crept in boost

when you turbo your car you should take care of these things TOP priority. always check your oil level everytime you gas up and get a turbo timer and let your motor warm up b4 you belt it. people nock on turbos because they cant do a hack *** job on a turbosetup and expect it to work or they are honest with themselves and say its just too expensive

what did you like better? what kind of differences did you notice between the two power wise and such?

 

I sold the JRSC and went with a turbo because I wanted more power... The JRSC is an awesome modification if just want more power on your daily driver. The power curve is smooth and very driveable throughout the RPM range.

The statement above about your motor always being under boost with the JRSC is not true. There is a bypass valve on the intake manifold that opens while not in boost that bypasses the supercharger.

Reguarding the comment about JRSC's tearing up bearings, the JRSC has a 100,000 mile warranty, so if it does tear up, Jackson Racing will replace it.

The power of a JRSC is smooth and linear. The power of a turbo will come in harder and will cause wheel spin, etc. There is no need for a J&S safeguard on a JRSC kit, as all Prelude JRSC kits come with JRSC's computer and have a **** for adjusting timing on the fly. The 6lb pulley on a Prelude JRSC kit usually makes closer to 8lbs. Endyn, (www.theoldone.com) makes two pullies for the kit. Each pulley adds 2 lbs of boost for a total of 12 lbs. If you go over 10 lbs, since the JRSC turbines are "self clearing" Endyn recommends that you replace the stock blades with carbon fiber.

All in all, both the JRSC and turbo kits have their place. It's really what you want.

For a daily driver capable of mid to high 13's go with the JRSC

If you think you will ever want performance over that, go with the turbo.

 

^^ good information. I would have considered a jrsc if it was intercooled.

 

What about the heat with jrsc? Is it really a concern? Does it matter if you drive all day non-stop on the highway? How's gas consumption? Any big difference?

 

is there anyway to lower the intake charge temps? Also, what advantage does the vortec sc have over turbo? how much lag do people have with it?

 

Does anyone know of a centrifugal supercharger kit for the h22. Ive seen a civic with a kit but I believe it was custom. I would love an entire kit. but just the bracket for the supercharger on the motor would be great. Any one.

also so <TABLE WIDTH="90%" CELLSPACING=0 CELLPADDING=0 ALIGN=CENTER><TR><TD>Quote, originally posted by vinuneuro &raquo;</TD></TR><TR><TD CLASS="quote"> how much lag do people have with it?</TD></TR></TABLE>
there should be almost no lag if any with a supercharger.

Do you know what #'s people pull who have the 12 pully? Also, i would love to see the dyno of both your setups

 

JRSC do get pretty hot, though it's never been a problem for me. I keep an eye on my oil temp. Actually, I've had zero problems since it's been on, about 20K miles. This is also a daily driver. MPG might have actually went up slightly when I keep my foot out of it, and even running it hard I get ~about~ the same mpg as I did before the SC, 23-25 mpg on average, 70% highway.

 

ludetech, what you are saying is true, but out of all the honda engines to boost, the h series will give you the most headache stock, and this isnt opinion it is a fact.. you could have a great turbo setup on your h22 but once you start creeping into that ~275ish range, your bottom end will not last... cracked ringlands are almost inevitable eventually... also, you cant drop a forged piston into an h22 like a b series unsleeved...

 

i would suggest going turbo over going supercharged, because boost is an addiction. once you feel it, you need more. unfortunately since jackson racing is the only company that offers a supercharger for the prelude, there isn't much room for improvement after you install it. with turbos, the sky is the limit. i've got 266whp, and the first time i got on it after we dynotuned it..........it still didn't feel like enough. either way you go, i suggest building the block.

yes, vortech makes a centrifugal kit for h22s, centrifugal SCs have lag, which is honestly a good thing for me which is why I am considering one, its a good thing if u wanna drive the car normal and get good gas mileage all you have to do is keep it outta VTEC. the vortech sc kicks in almost the same time as VTEC, also this is beneficial for the motor, because it is putting the most strain on the motor when the motor can handle it best, and it has a blow off valve so it isnt constantly forcing boost in.
there is a great article in the new Sports Compact Car (april 2005) starting on page 130 that will give a lot of insight on SC's, great article, pick up a copy if u are asking questions about SC's on this thread.

 

Ive never see that SC. Do you have a link?

 

hey incubus where did you find the info for the vortech h22 kit. and also if you have lag then its because the pully has been made small so you dont get a certain amount of boost till a certain rpm. a centrifugal superchargers boost is linear compared to the engines rpm. lot like a turbo. if you use a vortech bypass valve you can run a pully for more psi and you can ween off whatever you dont need. so you can get your max boost pressure at a lower rpm. So if you know what your doing you can get rid of lag. but who needs full boost at idle on an h22. I think you would have a little bit of a traction problem.

but anyone who has any info for a vortech on an h22 let me know.
