    theres plenty of room for a turbo under the hood of the CRX.
    if you are going to keep this car under 500-600whp, you do NOT need to do any head work. just have it fixed.
    judging by no mention of forged internals, im assuming this is a stock bottom end. a feasible, reliable number on stock internals is somewhere around 250whp depending on the tune, and how well the enigne has been treated prior to the turbo install.
    a .63A/R 57 trim Garrett T3/T4 will get you there just fine, and still have a little breathing room as well. one of these: Garrett 57 Trim Journal Bearing Turbo T3/T4 T3 T4 T04E - eBay (item 290462923581 end time Apr-07-11 14:57:26 PDT)

    also, if you want reliability, make sure you focus on the little stuff. make sure your car doesnt leak/use oil, no check engine lights, and get a decent set of tires, suspension, and brakes before you do any of this.
