AEM + CTSC - Best fuel press reg?

[EVO IX]

I am converting to an AEM EMS on the NSX and need to know what the best fuel pressure regulator is to use with this combo. Is there a preferred brand or model?

I always use Aeromotive Fuel pressure regulators for my projects.

Just get a universal one for fuel injected applications and make sure it supports the pressures you need to run. You can typically set the baseline (with vacuum line removed) fuel pressure to 42psi and then it will rise 1:1 with boost. Therefore, if you run 18psi you will see 60psi of fuel pressure.

They even make some bolt on regulators for Honda's that may be compatible with the NSX.

P/N 13116 (92-97 1.6L VTEC)
86 - 89 Accord LXi/SEi 93 - 95 Del Sol S/Si
90 - 93 Accord 94 - 97 Del Sol VTEC
92 - 95 Civic 89 - 91 Prelude Si
99 - 00 Civic Si 94 - 01 Integra

P/N 13115 (98-01 2.3L VTEC)
98 - 02 Accord 4 cyl
96 - 97 Del Sol Si
00 - 04 S2000

Can these Honda regulators be mount on the fuel rail? I have the CT rails, this means I need an adapter, right?

Do not use the supplied FMU from Comptech, just keep your factory regulator in place on the fuel rail. By the way, I assume you have an early car if you're using the EMS. A good thing to look at will be to replace your factory fuel pump. We're starting to see quite a few of the factory pumps kick the bucket as they exceed their service life. A new pump will also be able to support the flow of the injectors you are using. We sell the complete kit here:

I just ordered one last week. How loud is it exactly?
