I plan on turboing my LS, running around 12 psi on stock internals, 450cc injectors, with a Hondata fuel management. I was reading on the hondata site, and I came under the impression that with Hondata, if you have bigger injectors, higher pressure fuel pumps were not needed. Is this the case? TIA

your title says water pump. A larger fuel pump with large injectors isn't necessary, but recomended.

 

ok, so then what would be recommended? the 255 lph pump or the 255 lph high pressure? I've been hearing about problems with idle with the high pressure, and I was wondering if it would be a problem.

 

the high pressure pump will only be needed if you are running a fmu setup. if you are using larger injectors with the hondata, smc or afc, the regular 255lph pump will be more than enough.
