hi , i have 2001 WS6 M6 , it between 400-430 RWHP , i'll spray 175HP , it's enough to upgrade the fuel pump only with stock injectors ?

thanks.

 

yes and yes

 

with stock injectors and walbro 255 fuel pump direct in tank and 175 shoot the tune will be okay and in safe way ?

 

please guys don't skip me i'm in problem now , i want to tune my car with 175 and i don't know what i do ! if i installed fuel pump without aftermarket injectors the tune will be okay ?

 

If you are on a dry shot, replace your injectors.

If you are using a wet shot, a walbro intake will be fine.

 

bryan @speedINC recommend me to run with walbro 255 direct in tank is this good for my application ? 175 wet shoot ?

 

Yes, that will work fine.

 

thanks a lot

 

let see new opinions

 

You should be good with just the 255 pump. It never hurts to know the duty cycle of the stock injectors when you're putting out 425+ on motor. If you have a solid tune with the stockers, you'll be fine with a 255.

 

thanks a lot , i ordered 255 walbro fuel pump direct in tank , i hope everything will be in safe way for 175HP

 

I simply bought the Racetronix kit...

I would do more than just replace the fuel pump. Replaceing the fuel pump with a walboro does not give you much room if any to grow. I would do the racetronix system. That will give you support up to 650 rear wheel hp. We sell the racetronix system for 249.00. Just about any vendor carries this system.

As to the injectors if your nitrous system is a wet system you do not have to worry about injectors as long as they are good enouigh to support the motor NA.

I think you'll need the hotwire (racetronix)set up not just a pump.
