I plan on hittihg around 250-300whp with 10lbs (t04e 60 trim) I am about to install the walbro pump, do I really need to rewire it? How do I check for voltage etc, what kind of voltage do I need? My car currently doesnt have the injectors or downpipe installed, I plan on doing that today, so I don't want to start the car.

I read a post where a buy installed a walbro and ran his civic to 400whp without rewiring it. I did buy 12 gauge wire, I did buy a 12v 4 prong 30 amp relay. I have the stuff to rewire it, but I keep asking myself is it necessary. I eventually want to build a block, and up the boost, so I know yall will say rewire it, but will I be okay on stock wiring until I up the boost? If I had someone explain how to install this goddamn relay I would do it no problem. I don't know which wires to tap etc.

Any help works. I read threads where it shows what wires go where, but I don't want to wire this **** incorrectly.

Thanks for any replies

 

you'll be fine without rewiring.

 

****, anyone else wanna chime in? I really hope so cause for some awkward reasons I'm dreading the rewire, meh. I know how to do it, but just paranoid about wiring it and hiding the relay.

 

just replace the pump that's in your gas tank currently. I had a 250whp civic with a single cam and just swapped a walbro in it and done. I am currently going for 400+ without rewiring my fuel pump. to be honestly never really heard of rewiring a pump just for a 255 walbro

 

I have an old standard walbro 255 not the hp version with a bse pressure of 50 psi at the rail and makign 400whp on 18 psi boost. Its overworking the pump andc its all on factory wiring but its been holding for years

 

Thanks for the Replies guys.
