Trying to decide whether to go with FIC 1050s or FIC 950s on my stock IX turbo (other mods listed below). I'll be using a Walbro pump. I'm kinda getting the feeling the FIC 1050s are a bit overkill. Would like to get the smallest size injector that will get the job done. I don't have plans to ever go with a big turbo or other mods except perhaps a FMIC and better DV setup as I intend to stay on the stock clutch. For anyone running FIC 1050s, could you post your IDC, afr, load, and whp at peak whp? Thanks!

My Fic 1050cc IDC is at 90% at 7500 rpm
28 psi, Don't know AFR since I don't have wide band. But according to Stock narrow band O2 reading, It is .89 Volt. My car recorded 372 DLLHP with stock evo 8 turbo HFC, and stock cat back with modified muffler.

I wish I should have gone even higher with E85 like 1150 cc.

I have 1150cc FIC, but my duty cycles hit as high as 93% at 8500 @ 29-30psi with an 11.5-11.7 a/f. You have a stock turbo and only pushing 24psi so 950cc would probably be enough. You might as well get as big as you can while not sacrificing driveability (1150cc) in case you upgrade in the future. With my turbo, a single walbro and 880cc injectors I maxed out around 22psi on my 35r. After adding a second inline fuel pump, an aeromotive FPR and 1150cc injectors I got the above stats and can probably push it to hold about 32psi before maxing out completely.

Thanks. I ended up ordering the 1050s because the spray pattern is much better than the 950s.
