I don't follow you Norma.
What kind of Denso?

If it is an off the shelf MSD ignition system made in the states and you
want
to install it on an RX7 it depends on what year RX7 car you have.
Late years used computers and earlier cars used points
and a distributor. What year car do you have?

Hi Paul,

I drive a 1985 RX7 PP. I drag race with this car. The engine used to be in a
RX7, and I put it in a RX3, but it is a bit slow.  I dont know what is wrong
.... it has 4 wires, red, white, black, white/green.... maybe you can help me.

Go to this web site and download the 1985 RX7 shop manual.
http://foxed.ca/rx7manual/85_manual.html
Download the 6.9 megabyte wiring diagram.

Here are four examples of what you will find in that pdf.

If you are using the 1985 RX7 stock Emissions Control Unit
and the stock intake manifold the lack of power is unlikely
to be anything to do with the ignition unless something has
failed.

One way of increasing the power is to modify
the air flow meter. You need to trick the emissions control
unit into thinking the engine is getting more air than
it really is so the EMC will increase the fuel and richen the
mixture. You do that by weakening the spring on the trap door
of the air flow meter. That is about all you can do with the
stock unit.

Are you running a carburetor?

If so that changes everything and it will be up to you to
get the ignition to work with the MSD. I can help you there.

In that case there is a lot you can do with the intake manifold
system to increase the power.

Is the engine a 12A or 13B?
