I've got a 2001 JRSC'd GSR, and have a Hondata s300. It's currently running 6lbs boost on the JRSC FMU and black box.

Going with a 440cc injector and using the s300, what part(s) will I be able to eliminate? I plan on driving it on a base map w/ the s300 for a while before cranking up the boost. Then, I plan on getting a tune.

I bought the car w/ the JRSC installed. So, I didn't do the install, myself. So, I wanted to ask some of you guys w/ JRSC experience what would be the best thing to do.

 

You don't need the FMU, black box "powercard", and fuel enrichment relay if you have an s300 controlling things. On the intake manifold, you'll want to hook up the MAP sensor via a short hose to where the fuel enrichment relay pressure switch is located. Block off the stock map sensor location on the throttle body with a plate. I think that should do it.

If you can get some before and after dyno numbers, I'd be interested in hearing them.

You might want to do a Walbro fuel pump while you're at it ($100), and a new oem fuel filter ($20) wouldn't hurt.

 

Appreciate it, Tronic.

It's already running an aftermarket fuel pump. IT HAS TO BE!! That **** be buzzin' like crazy!

As for b4/after numbers, IDK if I'll be able to do that. I was trying to wait to have to go to a dyno until after I swap crank pulleys to the CRV pulley. A few tuners told me I'd be better off w/ the s300 and a JRSC basemap than on the FMU/black box....ideally, it'd be completely tuned on the setup, but since this setup isn't permanent, figured I'd go with the better of the 2. Since I have the s300, figured I'd go ahead and put it on and load a basemap. They say it'll clean up how the car runs a bit.

 

+2 on removing the jackson racing fmu/iat relay/piggyback.

John...you think I'll be ok boosting 6lbs on a good basemap?

Is there anything I need to pick up in addition to the injectors?

John/Phearable made me a CROME basemap for RC440's, JRSC on a GSR/ITR B18C, boosting 9-10psi with a CRV crank pulley. Worked fine for some initial street testing and the hour-long drive to the tuner, where it was close enough to dial it in with the VAFC that was already hooked up (some cam and ignition timing changes were made also).
