  1. 1.5T Getting limited by the clutch ---Again

    Yeah man, I’m trying to keep it a beast but still daily-drivable — not easy. I really thought the RV6 combo would be enough, but apparently it’s just barely not there.
  2. 1.5T Getting limited by the clutch ---Again

    On my 1.5T Civic build journey, the clutch has consistently been the weak link. When I was running the stock turbo with ethanol injection, the OEM clutch started slipping pretty quickly. I upgraded to an EXEDY street performance clutch, which held fine at around 230–240 whp (stock was roughly...
  3. 1.5T About non-Si fuel upgrade

    Your products are extremely hardcore and cool. To be honest, I more or less followed your approach. In mainland China, purchasing your excellent products is very expensive, so I used many used OEM parts from dismantled vehicles to complete the build. In the end, the results turned out quite...

  10. 1.5T The Rebuild Journey of the L15C9(Non-Si) Engine

    I'm using a used part from an RDX. People who sell used parts usually aren't as careful with them as we are, so it's very likely that it has been dropped or pressed at some point. However, given the structure of a high-pressure fuel pump, metal fatigue is unlikely to occur. The hand in the photo...
  11. 1.5T The Rebuild Journey of the L15C9(Non-Si) Engine

    Still in the break-in period, I encountered a sudden P0028 fault during slow city driving. I noticed the DIFP dropped to 0.4 bar—sure enough, the high-pressure fuel pump had failed. When I removed the old 6B2 pump, I was surprised to find it had actually broken, which is extremely rare. Since...
  12. 1.5T The Rebuild Journey of the L15C9(Non-Si) Engine

    The thermostat is quite inexpensive. Although the one for the 11th-gen costs about twice as much as the one for the 10th-gen, it's still only around $30. Maybe I could send a few to fellow enthusiasts in the U.S. who need one.
  13. 1.5T The Rebuild Journey of the L15C9(Non-Si) Engine

    I'm in China, and suppliers here can provide custom thermostats at any temperature setting. Most off-the-shelf products, like those from Spoon, are set to 68°C — just like the one I'm currently using. I believe they're not suitable for street use, as the coolant temperature often stays below 80°C
  14. 1.5T The Rebuild Journey of the L15C9(Non-Si) Engine

    Temp issue update: After testing, the coolant temperature issue was caused by the thermostat. I replaced it with a 68°C thermostat, and the water temperature now stays steadily at around 80°C. However, during ground cruising, the temperature often drops below 80°C, so I think I will replace it...
  15. 1.5T The Rebuild Journey of the L15C9(Non-Si) Engine

    Let me give you a progress update. In the end, I used a brand-new 59B engine block, which includes additional water jacket support. Inside the block, I used a 10th-gen Civic crankshaft, forged connecting rods, forged pistons, and oil squirters. You will need to continue using the 11th-gen timing...
  16. TSP L15CA Built Shortblock - Available for Pre-Order!

    Exciting update! I took a close look at the short block link on the TSP website and have some questions. It looks like the deck surface has been machined quite a bit—the coolant passages between the cylinders are almost flattened. Why did TSP choose to do this? Additionally, with the deck...
  17. 1.5T About non-Si fuel upgrade

    Let me update you on my progress. First, I'm mimicking the setup of American car enthusiasts, similar to DIY projects and Axion/FK8TD kits from forums. I purchased the fuel injectors and high-pressure fuel pump from the Acura RDX 2.0T, both with the part number 6B2. I believe I can use the...
  18. 1.5T About non-Si fuel upgrade

    Hello, brothers. I want to upgrade the fuel system on my Chinese model and have referred to all the 10th-generation Civic upgrade plans I could find. I think using the fuel injection system from the 2.0T Accord (the equivalent model in China being the Acura RDX 2.0T) could be an effective try...
  19. Acuity Instruments short shifter installed

    You can directly use Acuity's Stage 2 kit designed for the 11th-gen Civic; I think it can meet the needs of most people.

    Super cool feature, hope it can be made available for regular models, such as the 2022+ 1.5T models in China
