    X charger on 185 motor question..

    I am Puttin a x charger on my 185 motor. 60hrs on motor.
    42 injectors, x charger, external ic, 215 ecu, still have to buy rrfpr. My question is should I buy the supertech dual springs an retainers ? I'm already a little worried about putting a x charger on the non forged Pistons , so I don't want to have to worry about 2 things. And the motor is a 04, out of a gtx. Should I do the springs an retainers ?

    thanks in advance. And if you know any tricks or any info on making the 185 motor more reliable with the x charger please let me know.

    If you did not change flywheel you have the wrong gear set for it.
    Oh and the cast pistons will be just fine. We have ran 2Rudes with them for over 100hours. Just tune it for 11.9 and you will be fine.

    Oh yea and the stock 215 ECU has a 8100 limiter so springs and retainers are not needed. You are fine.

    I have an x charger on my 185 but i put the 17 tooth cog on the charger so it would mate with the 185 flywheel. Works great. Pulled 70 mph the other day at 7800. Air temp was 106 F so that probably slowed it down a bit.
