Do i need a Fuel pump?
hey guys, i have a Down pipe, mid pipe, and HKS super dragger cat back.
i bought a intake today with polished alum lines, and 2 K&N filters.
Im thinking i should get a Fuel pump, but im not 100% sure if i have to do it yet. I havnt installed the intake yet, im going to wait until i know if i need a fuel pump or not. thanks allot.
Also if i do, what would be a wise choice?
thanks to all,
-Mark

A common favorite is the Walbro 255lph.
However, with your mods, I do not believe you NEED a fuel pump. If you are running stock injectors and ECU, it would be a mod "just to mod".

Like it was said above you don't NEED it, but it is a simple thing to get out of the way if you intend on modifying further. Pumps are relitively cheap and take about 30 min to install.
....Though with the mods that you mentioned I do hope that you have added more fuel by some means (PowerFC, modified ECU, or some other way). If not you are going to be running a tad lean...

Boost creep is a biotch. Im talking from experience. I put my dp, mp, and intake system on and blew my car up within 2 months. Don't be surprised if you see boost spikes toward the 14-18psi range. This can be deadly to your motor.

I personally prefer the supra pump over the walbro. If you plan to make anything over 290-300 rwhp, definitely look into upgrading the pump. One thing to consider: these cars are getting older, and personally I feel a lot better blasting down the highway with a newer fuel pump vs one from 1992.

I am with Rich on the supra (nippondenso) fuel pump as well. That is what I have in my car and really they are only $200 so again one of the cheapest mods to do on the car.
That is interesting on the lack of spiking and creeping. I had one of those spikes last night to about 16psi. Currently I am troubleshooting a problem with my profecB SpecII so it wasn't connected.
