Ready, Steady, Brap!

Yes "brap", and plenty of it! This past weekend the RE-Zelse team was working on the Blueberry's motor at Wankel Works. Luis and Raul from Wankel Works allowed the team to work with them throughout the build. When the motor was broken down Luis was able to spot weaknesses in my previous porting. Needless to say, Luis custom ported the irons.

The motor had roughly 25,000 miles on it before I pulled it out. After the engine pieces were examined All of the seals, rotors, and irons were in perfect working order, internally speaking.

With everything disassembled, the cleaning began. This was the roughest part of the entire rebuild process. Every nook and cranny needed to be cleaned of all of the build up before the porting could begin.

With the cleaning finished, the porting can now commence. Luis port matched the entire motor after expanding my existing ports. I cannot show off his port job, but I can show my old ports verse the OE ports on the front iron. I also have this great picture of me giving porting a try as well!

Because my apex and corner seals were in near perfect condition, I chose to reuse them again. Here they are ready to drop into the motor.

After assembling the rotors we were ready to move on to the housings. We used Hylomar to seal the housings and irons together which should ensure a strong bond.

We continued to assemble the motor into the early hours of Sunday night. As I mentioned in my first blog post, I am going to use the RX-7 FD oil pressure regulator for higher oil pressure throughout the system.

Then we slapped the oil pan on, and continued to finish the rebuild. I cannot express enough thanks to Luis and Raul at Wankel Works for everything and for allowing the team to help build this motor.

We have a good amount of video footage to go through for a follow up post with the build overview and the shenanigans that occurred. Before I head back into the garage and get ready to swap these motors, I've got some other updates with the Blueberry.

My track days have been added to the team schedule and the first event will be at New Jersey Motorsports Park from April 21st to April 22nd. This will be my third time at the track. Boy, things have surely changed. Stay tuned for more updates and this season is starting to actively ramp up!
