I am begining my turbo project and will end up with a walbro 255 intank pump and an airteck inline fuel pump. I will also have a Vortec FMU and I already have a v-afc installed in my car. So my question is this. I am putting the turbo on my CRX with a b16 so should I buy injectors and do the hack or go with the FMU? Any input will be great. Thanks in advance!

 

buy injectors and do the hack

 

Anyone wondering FMU/AFC doesn't have the money for standalone + therefore is likely boosting a stock engine... so... go with one fuel pump or the other, both is overkill and pointless.

just to give you an idea: I've ran my stock HF pump at 9 psi with 450cc/AFC hack + chip to retard my ignition. The pump died after the car sat for two months, and I'm running 4-7 psi on a stock LS pump with no problems so far.

Depending on the efficiency/flow of your turbo, you may find your stock fuel pump dying at lower levels than I run, as I run a tiny crap turbo.

I advocate the AFC hack, with chipped ECU to overcome the increased ignition advance the AFC hack + OEM ECU gives you. There is no place for an FMU on a turbo Honda as the current technology stands.
