New to the Club!
Great 20B swap and build thread!
I have subscribed for more updates.
Looks like the oil pan mount is also going to work for the other vehicles and RX8 swap as well. The wing mount design is great, very sturdy, and adds a lot of rigidity to the whole block assembly. Many drift racing teams are using the "custom billet dry sump pan wing mount" to secure their rotary engine, 2 or 3 even 4 rotors, as long as you stretch/add more length to that oil pan mentioned in this thread, people could even fit 6 rotors with this pan; may need to add more mounting points, in my opinion.
Built2Apex used to make similar products for 3-rotor oil pan swap and dry sump solutions compared to the Mazda Cosmo OEM weird shape oil pan, but I couldn't get a hold of them at all, and seems like they are out of business, their website is down as well...
Interested to purchase two of them if they become available/for mass production; been searching hard and waiting for some good oil pans for my 3 rotor projects for almost 4 years.

As far as my 20B build goes, it's on hold as I repair Ice Storm damage to our property. We lost 5 trees, one through the roof of my office. Sadly several cars parked outside were damaged. What do you do, it's Mother Nature. Repair, rebuild, move on.
Originally I wanted to make this a bolt in complete kit - but I changed my mind half way through. After talking with four people, who all had different transmission options - I decided that this will be sold as a pan and hardware kit. Rob may change this at some point in the near future. There are some great benefits to this iMO- those with T56, CD009, DST, OEM can set the engine where it best fits, weld tabs on the Ronin subframe, and have the perfect fitment for their build. Those who want to cut/modify their tunnel can take it even further back. You will need to build a transmission mount, driveshaft, and look at using either a SIKKY diff mount or a Ford 8.8 swap. I guess my point here is, if enough people wanted a stock drop in - parts like the fancy shifter relocation and pre-built subframe would be worth it. But I'm trying to be realistic as to where the market is at. With 20B's fetching 10k for a block, these are being built for power - not OEM.
With all of that said, here's what Rob plans on including with the pan.
20B Oil Pan - REW Front Cover bolt pattern
Hardware Kit
O-Ring
OEM Rx-8 oil pickup
Drain plug
Here's what you would need:
1) Ronin builders subframe
2) Ronin bump steer kit
3) Low profile motor mounts - like IRP or Banzai. I'm trying these from Revshift. https://revshift.com/collections/maz...azda-miata-mx5
4) Differential mount - https://www.sikky.com/product/mazda-...rential-brace/
5) Transmission mount - depending on your use case
6) Drive shaft - depending on your use case
7) Xcessive LIM - Ensures the best fit/hood clearance.
Two things to note.
1) This pan could easily be adapted to another chassis - I'm using one in a engine swap right now. I'm trying to find a FC and FB/SA shell to test next. We know it fits several classic Toyota chassis.
2) Rob is discussing making a 13B-RE/20B-RE oem front cover version. Email him if you are interested.
I hope you guys find this helpful and if you have any questions, just let me know.
