WHAT DID YOU DO TO YOUR FRS TODAY?

[DarkSunrise]

Switched back to e85. Car feels and sounds great! Amazing how a few mods transform the FA20.

Also went on the first canyon drive of 2022 with some friends. Excuse my dirty car (rained during my last track day).

I don't, unfortunately. But this is what I used, cut into strips 8in by 36in. It fits snug enough into the channel between the outer body panel and the inner framing that you don't have to tape it or anything. I inserted it from the front, near the speaker, then went around and pulled it through to the back.

Everything but the four bits of dynamat under the front seats looks like it could be put in by removing a couple of trim pieces & lifting the carpet? Or am I overly optimistic?

Technically yes, but the seats aren't hard to take out, and once you've got the seats/console/trim pieces out, the carpet is pretty easy. I'm actually impressed how relatively simple the disassembly of the interior is on this car. The biggest PITA so far has been getting the hooks on the back seats to engage when putting them back in.

I installed a new starter battery. The old one was getting pretty weak. Whenever I start the car in the morning the radio turns off. I guess the battery doesn't have enough power to run the radio and the starter. So the radio is sacrificed. I've been using these 18 Amp Hr SLA batteries for about 8 years now and they work great here in Florida. They only last a couple years but they only cost about 38 bucks. And they're a lot lighter and compact than the OEM battery. Plus I have the Phantom ESC so I need 3 of these and 2 9 Amp batteries.
Now I need to break out the manual so I can reset the radio, clock, shift light, gear indicator, rev indicator and buzzer. (even though the car is so loud you can't hear the buzzer)

Oil change. Fumoto drain valve. Oil analysis mailed out.

In 3k more miles it'll be diff/trans fluid changes

So I got my car up and running on the twin AMR500 s/c setup. I'm working with Steve99 here on the forums with a remote tune and currently troubleshooting really rich conditions. Just sent him a log a few minutes ago, so hopefully we'll be able to figure it out and straighten it out here pretty soon...

I'm excited. Even running super rich, it was remarkably faster, but of course it should be. It should've just increased by 70-85whp...lol...

It's probably not quite that much more powerful yet since it's running so rich, so we'll see.

Anyways, soon I'll put together a full build thread and post some videos and some dragy results.

Valves Control on the FA20 Engine

[blsfrs]

I hear that you can adjust the clearance by adding extra sealant.

we set the valves specifically to a tenth so that the engine runs smoothly. many think it has hydraulic valve lifters but that is wrong. The valves have to be adjusted every 60,000 km

The FA20 has shims??

Track or street driving? Most of us aren't going pull our engines to adjust the valves at 40,000 miles.

So, you're saying I should have dropped my engine and adjusted the valves 5 times by now? Even though there's nothing wrong with them?
Damn, it's a big enough PITA just to drop the tranny every 100,000 miles to replace the TOB!

Did an autocross and gymkhana practice session today. Far more engaging than a track day - I should have started way sooner.

Bucket shim has very little wear, especially when a roller rocker is also incorporated. You may see some minor lash changes in the first service interval, not necessarily large enough to require adjustment. Further intervals typically see very little change if any. The rocker pivot sits in a galley and is acted on by pressurized oil. It is not acting as a hydraulic lash adjuster but probably does take up some play while the engine is running.

[blsfrs]

My understanding is the long term problem with lash is the loss of lash due to valve recession, not an increase due to wear and tear that you might see in a push rod engine.
