CARB compliance? EO number?

I don't like the feel of a metal knob, and anyhow metal gets way too hot in SoCal. I loved the Razo weighted (400g) leather grip knob I had in my 2007 Si (FA5), but for whatever reason, it did not feel good in the FL5, especially 5th and 6th gears. felt like it twisted the wrong way. I tried...

Wait, isn't our cat part of the downpipe, which means it is not easily accessible for thieve...

Thank you, I did a quick internet search SafeCat is a dealer-installed catalytic converter protection system developed by Auto Prime Financial Services, marketed through automotive dealerships in the United States. The system costs approximately $299–$500 and includes up to $6,000 in...

Which is one of the reasons I just got Cobb intake (CARB EO number D-660-272) The other is that I will shortly get the Cobb AccessPort Both standard and carbon fiber PRL HVI have SEMA SC-E approval for 49 states but neither has a CARB EO. When I asked, PRL said it was due to the high cost of...

by default yes. However, I created my own Grog custom instructions which are about two pages long. these instructions were designed to override the "hallucination" issue, and make it not "think" but rather just research the internet and summarize its findings. it is a very useful time saver...

The guy in the video is a Toyota mechanic, so I asked Grok about Toyota engines. The guy is wrong! Toyota indeed has variable displacement oil pump, but it is the same across all regions and oil weights... again, per Grok: Toyota engines, such as those in the Dynamic Force series like the...

Grok says: The Honda Civic Type R FL5 employs the K20C1 engine, which utilizes a fixed positive displacement gerotor-type oil pump. This pump is mechanically driven by the crankshaft, with its rotational speed directly proportional to engine revolutions per minute. It does not incorporate...

my issue with Honda is that the "fix" for the recall is not a fix, it is a workaround bad metaloury the primary cause of the steering issue was an insufficient annealing process during the production of the steering gearbox worm wheel and a high-load single unit break-in process during...

I read so many forums and discussion lately, but I believe this was from Bob is the oil guy site

Thank you! I think I finally get it... Since I do not track, and in So Cal, Pennzoil Ultra Platinum 5w30 at 4-5k miles Now, what about filter? I've been using Fram for my 07 FA5 Si but I read that Fram was purchased by some company (no longer Honeywell), and quality has gone down, plastic...

DOT 5 is NOT compatible with any other DOT. It does not have to do with the common reservoir. it has to do with the chemistry of DOT 5 however, DOT 5.1 is compatible with DOT 3 and DOT 4 DOT 3, DOT 4, and DOT 5.1 are all glycol-ether based fluids DOT 5 is silicone-based, typically containing...

As far as I recall, it was indeed British privateers that captured the ship carrying the Metric prototypes from France to Jefferson who was an advocate of the decimal system...

Correct, hygroscopic by design, but some formulation absorb more water quicker, and some formulations absorb less water and slower. Water vapor is compressible, not a good thing in brake system, which is why I believe that wet boiling point is an important measure, even if not racing, as it...

I agree, even worse when you grew up in a metric country, and after 45+ years in the US you lost your ability to guesstimate in metric and still have not gained the ability to guesstimate in imperial on the other hand, at least metric is consistent. 1 ml water is 1 gram and has volume of 1...

Back to oil weight... I did even more reading, specifically for the K20C1 Seems that this engine has issue with fuel dilution Which means that 5W30 might be better than 0W20? How quickly does a 0w20 dilutes to 16 weight oil? How quickly does a 5W30 dilutes to 20 weight oil?

Which is why I was looking at fluids with three year change intervals

Thanks, did not occur to me to check viscosity! Fuchs Titan DOT 514 LV Dry Boiling Point: 270°C Wet Boiling Point: 180°C Cold viscosity at -40C: 750 mm2/s Change Interval: 2 years Bosch has lower viscosity, and longer recommended change interval (lower hygroscopicity) Bosch ESI6-32N Brake...

For what it's worth, this is from my research when I was looking for brake fluid. I evaluated based on dry/web boiling point and hygroscopicity (if that's even a word) judged by manufacturer's recommended change interval, looking for change interval of more than 2 years which is the standard...

Thanks, I do suffer from CDO and a recovering perfectionist who keeps falling off the wagon. I am probably over analyzing and overthinking my quest for the perfect oil that will keep my engine and turbo running forever. (this is probably going to be my last car, as I do not believe that there...
