    Would you recommend installing the entire jrsc, including alternator and all belts before dropping the motor back into car? Would I experience any issues with clearance?

    I will be running the mvm stepper pulley [img]smile.gif[/img] but I am concerned about heatsoak. Is anybody running mvm pulley without a water injection or lht? What are you thoughts.

    If the engine is out of the car... install the JRSC BEFORE you put the engine back in !!! It is much easier that way and there are no additional clearance issues.

    MANY MANY people run 8-10 psi without water injection or the LHT intercooler... we did it far before these products were available. With proper tuning, you will be just fine.

    i ran 9 psi with no water injection and just the JR band aids. two cylinders now have 20% leakage and compression is now at 135 [img]frown.gif[/img] i suspect #3 & 4 ringlands are gone.

    actually, on the dyno, the readings were giving us 11.5 psi, not 9.

    I ran 10-11 PSI both with the FMU/stock injectors and with a Hondata S200/RC440 injectors.

    With the FMU, MAP controller, BTC, and Walbro 255 fuel pump, I found that it ran crappily for a couple of days and then broke all the rings and ring lands on my pistons.

    After a rebuild, I opted for the Hondata S200 with RC440 injectors and it worked very well.
