1.5T About non-Si fuel upgrade

[PangziXin]

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. However, there is one thing I haven't figured out yet, which is the selection of the intake camshaft. In the 11th generation models, the OE number for the intake camshaft is different from the previous ones. I know that for the U.S. versions, using the Si intake camshaft along with the 2.0T high-pressure fuel pump works, so I want to confirm the intake camshaft and high-pressure fuel pump numbers for the U.S. 11th-generation models so I can find the corresponding parts in China. I hope someone can provide this information. Thank you very much.

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 10th-gen Civic Si's 5pa high-pressure fuel pump base and hard lines, and enlarge the holes in the hard lines to about 1/16 inch. Additionally, I bought an intake camshaft from the Chinese-market CR-V, with the part number 68D (the U.S. version Si has part number 64B). Once I receive the part, I will compare it with the 10th-gen Si intake camshaft. I’ve also made wiring for the fuel injector power supply. The low-pressure fuel pump is straightforward, as the DW300C is easily available. The main challenges are the compatibility between the camshaft and the high-pressure fuel pump, as well as the subsequent fuel pressure calibration. I will continue to update.

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 good.
By the way, I’ve been watching your K20C swap videos recently — they are seriously awesome.
