Rotary Questions
Im doing some research on the 12a and 13b to gain some knowledge since I am studying to be a mechanic. Now my questions...
How do you put it on time? (like in a piston motor...when you time the cams and the pistons to work adjacently)
When you want to build a racing motor...what exactly do you change from the internals? Do you change the same things if you plan on doing a turbo setup?
And finally...How do you know where the redline is after you build it?
Im sorry for the noob questions but like I said Im trying to learn more about them. Thanks for the help...rep will be givin to those who can help me out.

How do you put it on time? (like in a piston motor...when you time the cams and the pistons to work adjacently)
Well rotaries are completely different from putting your average piston motor due to every rotary has 2 different sides of ignition your trailing and leading.Every rotary has 2 marks in the crankshaft pulley which indicate trailing and leading.Now it depends what your putting in timing ,a ROTARY WITH A CRANK SENSOR or a rotary with a distributor.
When you want to build a racing motor...what exactly do you change from the internals? Do you change the same things if you plan on doing a turbo setup?
This questioin really depends on what your building.
In a rotary motor there is low compression and high compression rotors.Like on piston motors there is sleeving for more boost but in a rotary there is adding more dowel pins so the motor can take more boost and reduce detonation.Internally theres parts that can be upgraded from apex seal to oil pressure regulators.Porting is one of the best bang for your buck in the rotary game.
And finally...How do you know where the redline is after you build it?
Well papa thats mainly on the experience of building the engine and know what you got.But the best way is put the car on the dyno and see where your making the most power and what RPM you start to lose power.thats the best way !!!
Im sorry for the noob questions but like I said Im trying to learn more about them. Thanks for the help...rep will be givin to those who can help me out. Now where's my rep ??? LOL

ElBrqua all i got to say is a warning if you go on rx7club, read before you post because unlike at tr they are unforgiving, and are extremely sarcastic. But in honesty your best bet is rx7club and wiki buddy.
