I was wanting to get larger injectors and a larger fuel pump.. who makes aftermarket injectors for maxima's?

 

the Z32 injectors & fuel pump would be a good place to start. The NA injectors are 259cc/min, the TT ones are 370cc/min. Supra TTs use the 300ZX TT fuel pumps when they push 700+ HP (they use two of them).

 

Walbro 255lph HP fuel pump. its part number GSS342

RC injector are real good, i've heard...

 

RC doesnt make 370cc or 440cc for the 4th gen Maximas. If you get 555cc they have an application for you.

does anyone know how much hp the Walbro pump is rated for>

 

who sells the Z32 injectors.. Nissan?

I think the Walbro GSS342 will hang with ya!

Good luck everyone!!!

 

Don't forget to get your ECU re-programmed to compensate for the new injectors.

use the 300TT pump, its about $300 from Nissan, works just fine, more than enough fuel.

who reprograms the ECU and how much does it cost?

 

JWT and it's $$$

 

~ $100 for the EPROM update if you've got the JWT ECU already.
