[FujiWaraFoolish]

I got a civic hatchback 2020 with Greddy DDR exhaust & DP w FP also with a Cold air intake. Tuners on its way. Wondering what kind of injectors do you guys recommend?

May I ask why you want to upgrade the injectors at this point? I'm not sure you are there yet, unless you have much bigger plans than what you have shared so far.

You would need to be pushing 29psi+ with E35-40 fuel to need aftermarket injectors. Built block is recommended for anyone going into 4bar map sensor territory.

Eman is the only one rn that has a direct injection fuel system for the 1.5T, SI cams required.
It's a intank fuel pump, hpfp, hpfp line, injectors. Costs $1900.

Si cams would be required to run the HPFP upgrade.

I'm guessing you are new to the platform. I'd spend some time reading various threads in the engine/powertrain sub forum and see what others are doing with their builds, and learn from other's success' and failures.

Did you do any kind of CSS/blockguard when you built?

I just don't understand what's taking so long for companies to come out with bigger injectors for DI systems. Diesel injector industry has been doing for decades, I know the injector is probably different but it should still be doable. I think DI has a lot more potential than port injection overall and don't get why the industry is hellbent on not changing to DI performance injectors on cars that have it.

Apologies in advance. I’m very new to the civic 10th gen models. But adding what I have now. Wouldn’t I hit fuel cut?

I don’t think so. Your DP will probably be what gives you the biggest difference in performance. I don’t think the rest make a big difference.
Others have a W1 turbo with flex fuel and still stay within the limits. Given they’re not using a built block and pushing the boost.

No you are long way from that. Even after upgrading the turbo you can do quite a bit with the factory fuel system. It's when you start to get crazy like @kshawn that you need to look at upgrading.
