Hi

        Very new to the rotary engine, busy assembling rotary with help from dvd I purchased from atkins rotary but no where do they show how to time up the engine from scratch. Do you have information with pictures how to time up the engine pulley marks etc. Then secondly I'm changing the ignition distributor(single distributor) from normal points to electronic how to time up the ignition distributor. And done done how to set the timing on the engine when running ?

        Let me know ?

        Cheers

    Hi Paul

    Thanks, for all the information. In the process to get the engine right as it has to go into my Mazda Rx2 Coupe. So I bought this engine but this engine still has the following: breaker type distributor and I want to fit breakerless as per picture attached haven'r done it before so little bit unsure. Got the following of Racing Beats website were they mention timing and how to set it and values, they mention as starting point, do you still adjust from there ?  They mention a potential problem is this true in all cases ?

    Then engine oil cooler what will the minimum size need to be to keep the engine oil temp. at the correct temp. for standard engine ? With turbo/ supercharger fitted and without turbo/ suprecharger fitted ?



RB Quote:   " Distributor Upgrades"

"If you wish to install the 1981-85 RX-7 breakerless distributor in a stock 1974-79 engine, there is one potential problem: the centrifugal and vacuum advance characteristics of this distributor are slightly different from the original equipment "breaker point" style distributors. The easiest way to deal with this is to set the timing to: Leading - 24° BTC / Trailing - 14° BTC at 5,000 RPM and use this as a starting point (vacuum disconnected). If you wish to use this distributor for racing purposes, the vacuum advance should not be used, and the timing should be set to the proper
total advance setting."  (shown in the attached jpg.)

As you can see I have a lot of questions.

Barend.

I think RB assumes you are going to fine tune the timing on a dyno for racing.
For a street car that is not necessary.

If the HP is higher with the turbo you need a more effective cooling system.
Same rule of thumb. One third of the cooling is done by the oil.
The turbo cooling oil itself only adds a small amount to the oil temperature.

BTW I loved my RX2. Great car. I wish I had it back with an RX8 engine.
It only weigh about 2200 pounds while the RX8 is over 3000 pounds.
I'd chop and channel it :)
