hey watz up...i have an lsvtec integra..i just wanna know if i could use my stock ls fuel setup in the gsr head...thankz

 

It depends how much power youre looking to make. If its just something mild below 180whp than just get it tuned and you should be ok. Unless Im unaware of how efficient the stock LS fuel system is.

 

I would want to have a better fuel pump in a car like that.

 

i would recommend to get a fuel pump and at least 310cc

 

Depends on mods and the tune of your engine.

I personally have a B20/VTEC with the stock 240cc injectors, an AEM fuel rail, and regulator. According to CROME, my injector duty cycle is estimated at 84%, running full-tilt at redline WOT. To some people, 84% is acceptable, in all honesty I wouldn't push over 75% duty-cycle.

Get some 310cc injectors and a Walbro pump. You won't be disappointed, and it's an additional safeguard to blowing your engine.
