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.

RX7 in DAGO

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.

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.
