How are you going to control that much fuel? Your sig does not list anything for this...

The Walbro should be good for over 400 hp.
4x 720 should be good for beyond 300 rwhp.

You need a standalone ECU to control 900's. S-AFC will have a hard time compensating. You can send your injectors to RC for a porting job. Cost is around $175/ea.

the 4x720 will handle about 450hp at engine, over 350 at wheels

Always keep in mind the brake specific horsepower your injectors can
support. too much is just to much. big injectors do not deliver a good atomized fuel spray. More small injaectors is always better. If you want
a good stand alone engine management system chek out the new
Wolf 3d v4.0. If you want more info send a reply.

i got a haltech e6k sitting in my room and now i am try ing to get a list of the rest of the parts 9i am going to order. i dont know if 4 720's is going to be enough in the long run or not for my hp goals. can i send mty stock injectors out to be ported? i am planning on running the stock turbo at around 11 to 12 psi till i can save up for a ic and to4. when i get that i am wanting around 350 to the wheels. and i knew that the limit to this setup is right around there. is rxy.com the only place to buy fuel injectors? so any info would be greatly aprreciated
