I'm thinking about using the injectors and = fuel=20 rails that came with the
RX 8.  I also plan on using the RX-8 = ignition coils.  I don't know if
the regulator will work on a = N/A=20 application because it is not
referenced to the manifold = pressure.  I=20 ordered an adapter for the oil
injection pump to use 2 cycle = oil.  I=20 believe you will need a starter
from an RX-7 engine to use with = Tracy's RD=20 -1C.  I'm not planning to
tear my engine apart at this = time.  I=20 hope to use the alternator

bolt at a time and RTV it without=20 disturbing anything else.
