I have some questions for all you guys with a jackson racing supercharger:
1) did you have to put in an aftermarket fuel pump (ie warlboro 255lph)?
2) if you use the supplied fmu did you upgrade the injectors?
3) is the installation pretty straight forward? if not does anyone have the instructions from jackson racing that they wouldnt mind scanning and sharing?
thanks for your help guys

1) Stock fuel pump worked fine for 6 PSI

2) I used the FMU with stock injectors for a while at 6 PSI. Find a JR MAP Controller (I bought one used on ebay for $125) if you are doing that, as they want you to pull a lot of timing without it, which resulted in drivability issues.

3) Installation is simple, directions are on the web site:

I have the 10psi alternator pulley and rc 440 or 450 injectors. Will the stock fuel pump and fmu still work with these? Or do I need to get a tune and a warlboro 255lph fuel pump?

You will need a tune for the larger injectors and to run 10 PSI. You don't need the FMU for a tuned car with 440's or 450's.

I don't know that the Walbro pump is necessary, but it's cheap and just takes a few minutes to replace, so I replaced mine.

So if I want to run it at the 6psi with the fmu and stock injectors do I need that JR MAP Controller or can I run without it? Im going to stick with 6psi at first since I will have everything for it already, except maybe the Map Controller?
Thanks

You don't technically need the MAP Controller, but if you read the instructions it tells you to pull something like ten degrees of base timing, which can make your car run like crap off-boost in some situations, like ascending a mild grade. The MAP controller lets you restore most of your base timing and makes the car much more drivable. When I first started with a JRSC, the MAP controller made a huge difference in how much I enjoyed the car.

I wont need the map controller once I put the 10psi pulley and chipped and tuned ecu in will I? If not I'm gonna pass on it, but If it is something I sill still need later I might as well get it.

I had the 8 psi pulley (actually made 8.5) with stock fuel pump and it worked fine. had some RC 440's, AEM regulator. Fuel pressure set at a stock 40psi - so FPR prob not even needed.

Install is not too bad - there are a few quirks. If you are going to run 10psi I would really recommend getting a aquamist type system or one of the water to air intercooler setups made for them....my intake temps even on 8 psi got pretty up there.

JDMguy88

anyone have the 6psi pulley they would want to sell me?

streetracer6rpt

why spend all that money and run FMU garbage???

JDMguy88

cuz i dont want to spend the money on a chipped ecu setup and tuning. but eventualy i will do it the right way

streetracer6rpt

youre gonna wind up spending more if u dont do it right the first time...

JDMguy88

why do you say that?

Read my sig

JDMguy88

thats a good point, I think Im going to invest in a chip and tuned ecu setup with the 10psi pulley and 440cc injectors setup then!

Stock90Civic

It will pay off in the end, plus you get to enjoy that 10psi a lot sooner.

JDMguy88

Ok now that I have decided to go with the 10psi setup right away with larger injectors and a chipped ecu/tune, when I install the supercharger do I still need to pull some timing? If so how much?

rmcdaniels

No, your tuned ECU will pull the timing.

rmcdaniels you are the man! thanks for all of your help amigo!

rmcdaniels

NP, good luck with it.
