As some of you may know I'm actually removing my max engine & tranny for a complete rebuild, because I will be installing a V2 S/C I'm thinking of installing bigger injectors, so here is the 10$ question do I need to replace the fuel rail along with the injectors or can I keep it let me guess that 440cc should be good enough for the kind of power I'm looking for.

No need to change fuel rail completely. What you can do is cut out some of the crimped metal turns and replace them with smoother bending very hi quality flexible fuel line. The principle being the same as mandrel bending exhaust components.

The actual 5/16" diameter of the line itself is enough for some of the old Z cars to put down over 600 RWHP. 440 injectors (balanced and blueprinted)
along with a good nismo FPR and a hotwired hi pressure 255 fuel pump will be safe enough for over 500 WHP. If you're dreaming of higher numbers go to a 550 injector.

 

I'm probably looking at around 350-400HP to the wheel. The reason I asked is because I want to have the fuel rail chromed and if I need to replace it I wont bother. I'd like to bring the compression to 9:1 but I know I need new pistons, rods, I'll probably have the heads port & polish and get better spring, valves and retainers, any heads up where to buy those parts ( I can search but it's probably faster to ask )

Thanks I appreciated your input.

Cheers
