About to get my 98 wrx tuned at ASG with PFC and just wondering if its worthwhile changing injectors. Currently using stock vers 4 wrx injectors and rails.
Going to see what they recommend for boost.
Currently have a VF-37, headers,
tbe etc usual crap.
I understand I can just put sidefeed sti 440s in but will they fit in my fuel rails? Would it be worth putting in 99/00 rails or parallel aftermarket rails? Or better off with different injectors to the 440s?
Thanks for any help..
