    Default ra28 celica Conversion part confirmation list

    Guys.

    i've searched and found some info, but not definitive stuff.
    i need short but concise answers for alternative parts below.
    parts to be on parr with current on ra28 or better.

    1. smallest brake booster that fits. But can stop mx60 front discs with 18rgeu. I think std booster has 13/16 bore

    2. smallest brake master cylinder that fits, brake booster above. (std 4 bolt 1 inch bore.)

    3. most available top feed injectors 550cc and up, 11 or 14mm & ev1 or Oval plug
    - to clarify, using blank universal fuel rail.

    some backround, changing from std plenum to custom
    thanks.

    Heya Dude,

    Not aware of any certain fit Brake boosters but a long standing brake place should know. B&R Brakes at Castle Hill often have good referals on that stuff. Otherwise check out the Early Rolla stuff. (KE30 perhaps)
    Your master Cylinder will of course need to suit the new boosters Bolt pattern - If 4 Stud there are lots of options, the MA70 is my prefered for brake line outlet location and Reservoir size but there are a lot of cheaper 4 Bolt options around that 1 Inch upgrade size (landcruiser/Hilux etc)

    Re injectors make sure you get a spray pattern to suit your valves, 8 Valve engines and 16 valve engines need different spray patterns.
