who has done a dry sump system?what products will i need and what process will i need to take to get it to run effeciently?i want to do a 20b conversion later in life.but i want to keep the stock subframe and steering geometry.i will also be using a custom manifold to allow me to shove the engine as far down and back as forward.tia.

I remember seeing a system like that in my old Hayes Rotary catalog.

I don't think you are going to gain anything with a Dry Sump system on a Rotary Motor. The whole point to a Dry Sump is to keep the oil from whiping around the crank of the motor like molasis and robbing HP. Rotorys being different just don't have that problem.



A Dry Sump system will make oil changes easier, But that really has never been much of a problem either with a Rotary and the top mounted filter.

A dry sump system is exspensive for one,,now if your racing it, a dry system

would be worth the bucks..for a rotory engine it's a different kind of dry system completly made for rotory performance. a dry system oil pump runs

off the crank pulley via a cog belt. the oil 'sump' can be at least 2 gallons.

a baffle or windage tray is also required,,then remote oil filters,,guage.

not for street use.

for one.im not doing it to try tokeep from the eshaft from gettin wrapped up.if i ask how to do a dry sump ,help me out and answer my question instead of lecturing me on y not to,cuz i dont care.what i am doing it for?im preparing for a 3 rotor 3rd gen project.and i want to lower the engine as much as possible and push it back completely into the tranny/firewall area.

other than that i dont care for the street issue.i have a mechanic that gives me stickers to pass road issues.hey dago u have a pic or a site with a pic of this setup?

I don't see how a dry sump will give you more room???

Okay we understand. The Dry Sump uses a totally flat oil pan.



The Dry Sump system used in the Camel Light Racing Series used a gear driven front mounted internal pump.



I don't think too many people here if anyone is running a Dry Sump System.



You might check to see if a 13G (3 Rotor) System will fit.

Pineapple does it on 13B's for about $3000. You could try calling them to ask what they do.

where can i find out about a 13g?i hear so much about but i have never seen pics or specs.any info on this motor would help.

Dry Sump Systems and the 13G are shown and talked about in the HPBOOKS "How to Modify Your Mazda RX-7" by Dave Emanuel and Jim Downing.



Unfortunately this book has long been out of print.



The Date of this book is 1987 (just as the TURBO II) had come out.
