Hey guys and gals like the post says im looking for the best injectors and fuel pump to support 600 horsepower I have 2003 silverado ss with lq9 d1sc procharger with a comp cam and springs I plan on calling around to get some prices this Tuesday please help me out if you know if I should go with in tank pump or a inline pump and where I can find them thanks very much

 

FUEL INJECTOR CONNECTION - 1000CC BOSCH LS2, L92, LQ4 95LB FUEL INJE
These would be the biggest I would go. Should leave lots of room to grow. Smallest I would go would be 57lbs injectors they offer.

Fuel pump wise I would go AEM 320/aero stealth 340 on pump gas or Walbro 450 for E85. If you go bigger on fuel pump you will want a good vacuum referenced fuel pressure regulator.
SDparts has them in stock at great prices and they are a site supporter to boot.

 

Nice thanks and yeah thats something I forgot I will be running 93 bc no one around me tunes e85 thanks

 

Now are those aem 320 or the aero stealth 340 are those in tank pumps

 

Yes they are both intank drop in pumps.
