I have a stock 93 DX. What would the cost be if I do the install to throw in a jackson racing supercharger and run about 6lbs of boost? What kind of hp gains would I get?

 

I put a JRSC in my 96 DX and I regreted it so much, I sold the car. The gains were great with the 8 psi pulley. I was beating on stock GSR's, but there was no room for improvement after that. I would have been much happier even with just a turbo. Instead of junking a $2300 SC, I sold the car in favor of a crx with a b16. My advice to you is just save the little extra money and throw in a B16. The hp (I'm guessing) would be about the same with the 6 psi pulley on your motor, and then later you could always upgrade that motor and have much more.

 

I don't thinkt there is an easier more accurate way to find the answer to your question then by looking at jr's website and or e-bay for used kits.
As far as power goes, i'm sure JR lists dyno's from some cars on their site.
I would also recomend a turo over a s/c, you get a lot more power and versatility for the money.

 

Your situation is entirely dependent on your goals. If your goal is maximum possible power, best possible 400 meter (1/4 mile) times, and you're willing to deal with some lag (delay in power delivery), a turbo would be the best way for you to go. The cost can vary considerably, depending on the brand and whether you add things like an intercooler, stand alone management, turbo timer, etc. Going with a pre-packaged kit like Greddy or Edelbrock will give you better fitment, but will cost more than a "custom" turbo kit which you piece together yourself.

If you're like me, however, and your goal is more low to mid range power (for street driving), you have zero tolerance for lag, and you desire a relatively simple setup (no drilling/tapping oil pans, no turbo timers, no blow-off valves with their sound effects, no front mounted intercooler, etc.), a Roots-type supercharger (like JRSC) might be a better choice. I couldn't be happier with my choice. Here is my setup (00 Civic EX coupe 5 spd) and what I paid minus shipping (I got everything brand new):

Jackson Racing Supercharger, 6psi - $2349
Jackson Racing 190 L/h fuel pump - $89
Hondata S200 with programmed ECU and 440 mL injectors (deleted FMU and fuel enrichment relay, and installed OBDI IAT sensor in blower manifold per Hondata instructions) - $1305
OBDI IAT sensor (strongly recommended by Hondata) - $29
2 gaskets and several o-rings- $60

Total - approximately $4000

Yes it was expensive, but it was worth every penny to me. Everything else on the car (intake, exhaust, exh manifold, etc.) is 100% stock. I don't feel the need to go above 6 psi, and no I never dynoed or raced it. I installed the entire system by myself in my garage with a jack, 2 jackstands, and a large assortment of hand tools, including a 1.5 meter (5 foot) black iron pipe. No fabrication, drilling, tapping, etc, was required. After finishing the installation, I had to calibrate idle speed and ignition timing, zip tie a few hoses and wiring looms, and relocate the MAP sensor to read boost. The vehicle drives really well, with no detonation whatsoever (timing was left stock). Once again, this is no race car, but it's significantly faster than stock and actually has usable, instant torque! My number one goal was the preservation of the care-free Honda reliabilty and relatively low operating cost, not performance gains. Whichever path you choose, good luck

 

I just bought a JRSC about a month or so ago and love it. Running at 6 psi it runs with other B series swapped cars and no detonation. i will be ditching the fmu and going 8 psi with a dyno tune to make more power. best mod I have ever bought great power down low! The price for my jrsc was a little over $1700 the prices have dropped this year.

 

where are you paying 1305 bucks for hondata and 440 injectors :eek3: I wish I was your installer

 

$1,305 is kind of expensive for hondata and injectors. I paid about $465 for my hondata, $200 for my 756cc injectors and about $400 in tuning/labor (misc)

 

I installed everything myself. The $1305 is for a pre-programmed Honda p28 ECU (no tuning/programming required unless you heavily modify the engine, etc.), four fuel injectors (RC 440 mL), Hondata s200 interface box and OBD2B-OBD1 conversion adapter. This is why it's so expensive; it's just plug and play with no need to visit a dyno shop. It was a purchased at Jackson Racing's website.

The ECU's fuel and ignition tables are based on a vehicle equipped with the 190 L/h fuel pump (static fuel pressure at 42 psi), with stock intake, exh manifold, etc. VTEC engagement is preset at 4800 r/min. The ECU is tuned "conservatively", meaning that safety margins for detonation and idle quality were employed (at the expense of a few horses). Toyota uses this same approach of selling pre-programmed ECUs for use on Roots-type supercharger kits sold for their cars.
