So after many attempts I finally found my vacuum leak.

With the injector o-ring sitting down in the LIM this created a gap between the fuel rail and LIM. I resolved this issue by adding additional o-rings. I was able to find this leak by using a homemade smoke test.

The car idles so much better.

Another exciting news is I was able to get AC working kinda. The ac blows cold but it is on a manual switch to activate the compressor. For whatever reason, the AC relay is not working like it should. From what I understand, when the AC switch is pressed, it supposed to complete a ground which turns on the AC compressor. This is not taken place on the car for whatever reason. I’m currently on a PFC and tried to using a stock ECU and didn’t have any luck. I know about the trick about adding an additional relay and there is one there from the previous owner.

Next steps, remove old tint, get new tint on and figure out why my AC switch is not working like it should.

Did you swap out the compressor oil?

8/30 - picked up the car from the painter.

9/6 Assembled the car from 8:00 pm to 1:30 am. Back up at 5:00 to finish up and wash both the CYM and CW in prep for Cars and Coffee. Hung out at C&C, ran some errands and dropped off the car for tint. Old tint had to come off and got tint all around.

Super stoked on how the car turned out.

Damn Johnny, rocking all 99 Spec. I need to add more color to my collection lol.

The car looks great!!! Even though I would prefer the car to be as original as possible, you still have one beautiful and well put together CYM!! You've done a great job with the can and should be very proud if it!

Thxs guys.

I been cleaning up the interior and tinkering with a few things here and there.

Really need to get a r1 bar, also thinking about getting autoexe carbon intake and redoing the steering wheel.

Got a new center grille as the other one old and crusty looking.

Attachment 746777

Also got new door sills as the old ones were scratched and most of the mounting points were gone.

Attachment 746778

In the process of installing an OEM head unit. The previous person that installed, cut the wires instead of using an adapter kit. If this happened to you, you can order this piece.

Attachment 746779

While installing the radio, I decided to tackle this mess. Really hoping I don’t regret removing the keyless entry and aftermarket alarm system. This security stuff scares me and I just hope it starts when I’m done.

Looking forward to installing the following items from garage alpha

· Titanium strut nuts

· Titanium rx7 badge

· Floor mats

Man, I am looking at that pic yellow rx8 & yellow rx7fd.
Mine were red both..
That fd is looking really good...

Akomix 10-30-19 05:23 PM

Always enjoy seeing the progress Johnny. I have parts of mine getting ready to go to paint. I hope it turns out as nice as yours.

mazdaverx713b 11-03-19 06:58 AM

I think you're doing the right thing by removing the aftermarket keyless entry and alarm. When that stuff starts acting up a lot ends up going wacky and will have you chasing your tail. Car is still as beautiful as ever!

Johnny Kommavongsa 11-04-19 06:03 PM

^ thanks.

Good news I was able to remove the alarm and key less entry and the car still starts!

However when I lock the car from the outside and unlock it, the alarm goes off and the only way I'm able to turn it off is to disconnect the battery. Any reason why this is happening?

mazdaverx713b 12-02-19 05:52 AM

That's a very weird issue to have. Were you able to dig into it and see what the cause was?

Johnny Kommavongsa 12-19-19 05:28 PM

^ i thought i resolved it but still having issues.

Been driving the car on the weekends some and been planning on some big changes.

I need some more funds though. Been trying to sell some random stuff I have laying around. Check it out here: https://www.rx7club.com/3rd-generati...1140510/page2/

With a new decade beginning comes a new goal and a new setup. A week from now I plan on buying an integral part of my new adventure which is a 4 rotor setup. I bought my 2nd part yesterday which was S5 NA rotors. The first part was a IRP AMP alternator. Wasn't planning on buying this but I got a great deal locally.

High-level plans is a street friendly NA 4 rotor.

When I say street friendly, here is what I’m thinking
  • Idles below 1k rpms
  • OEM clutch pedal feel
  • Power steering
  • Heat and AC
  • Leverage OEMs rubber engine mounts

Engine setup
  • Majority of the parts will come from two new REW engines
  • Will sell the rotors and acquire 4 S5 NA rotors and use the hard seals from the S6 rotors
  • Rotating assembly balanced
  • Street-port side port
  • Custom oil feed to bearings
  • Wet sump. Don’t want to have to deal with external pump and oil reservoir
  • Upgraded mechanical water pump
  • Upgraded radiator and fans, thinking I may use Rx8 fans
  • I currently have dual setrab oil coolers but I think I have the smaller ones and will be upgrading to the larger ones
Fuel
  • Pump gas
  • Primary injectors only
  • Custom rail
Intake
  • ITB or plenum
Right now, I'm thinking the engine setup will look similar to this
Attachment 746377

Goal is to have everything running and functional for DGRR 2021

First couple of big task include
  • Buy new engines and have them at the shop by Jan 17th
  • Buy eshaft
  • Porting, iron machining, rotors matched weighted and ready for balancing by May

Narfle 12-31-19 12:12 PM

Just for the record. I have the rx8 fans, and I'm not convinced they're an upgrade from the FD fans. They do the job and look nice, anyways. Anything with sane side ports should be pretty streetable. Do people make wet sumps for the 4 rotor? A custom pan is probably not too big a deal to fab. To get the power plant low and back in the bay you may need the dry sump setup. God Speed.

Johnny Kommavongsa 12-31-19 12:38 PM

^ not sure on the 4 rotor wet sump question but I plan on getting a custom pan made and leveraging the stock oil pump. Engine will be mounted in the same place. That way I don't have to clearance the firewall, get a custom drive shaft made and make new mounts for the transmission. I know it's not ideal from a weight perspective but I think it will be fine for the street driving that I do.

estevan62274 01-01-20 10:10 AM

Awesome man! Cant wait to see more of the 4 rotor build.
Will be following closely :)

gmonsen 01-01-20 11:58 AM

This is going to be a great build, Johnny, and really pretty straightforward. Could actually get done in a year!

aplscrambles 01-07-20 03:02 PM

Looking forward to this, sounds like an "everyman's 4 rotor" type build. Keeping it streetable, and a/c and p/s. I like it. In for updates.

TitoBT87 01-16-20 03:21 PM

Looks sweet!!!

Will be interesting to see how all this plays out with everything going on with the economy.

Are you worried your FD will get the virus??? :egrin: Car is looking great. Looking forward to more 4 rotor updates.
