I found a subbie dealer that can get me new 520cc injectors for same the cost as oem 370cc. Im sticking with stock turbos but im uncomfortbale with the stock injectors reaching +80% duty cycle. I think these will be fine and 615s/740s would be overkill. Tons of sr and ka guys are running these but im surprised its not big in the z community yet. Found a few threads on tt.net but no real info on how they stack up. Theyre high impd injectors from 04-06 sti that drop right into 95+ rails. Only modification are the pigtails I believe. I like the idea as they are a newer fuel injector design made with ethanol fuel in mind and oxidizers as well.
I emailed ztuner and sz about it. Harry hasnt tune a vg with sti injectors but said he would help me out if I needed a custom rom. Greg prefers the nismo 740s, and from the tons of experience they had with the nismos i dont blame them. They prob know the 740 like the back of their hand. I think if we can get a few more ppl into these maybe there will be a big enough database to get more comprehensive and optimzed maps.
Anyways, just wondering if anyone else are running these and what experiences you had with them positve or negative.
