Injectors for my set up?

[joesansone17]

ok i have a 97 spyder gst, i want to know what you guys think about what size injectors i need for my setup.

I have a mitsu 16g, hks 264/272 cams, apexi safc etc. (all mods are in my profile)

Whats size do you think?

550's would be the easiest upgrade to tune with the AFC. However I don't think that these would support the higher rpm airflow you will be getting with the upgrades cams. Since you have the 255lph fuel pump and AFPR a skilled tuner might be able to make it work by increasing fuel pressure. But to take full advantage of the cams 660's would be a better choice. I have no experience tuning these with the AFC but I'm told it becomes a little more tricky. Hopefully someone with personal experience will lend some input.

I had a similar setup and the GReddy (denso) 660cc were great. The only reason I changed is I went from a Evo III 16g to a PTE SCM6152e, and needed more gas.

Get MAFT or DSMLINK and get 780's

I use 680's for tuning my evo 3 16g with a safc neo if that helps.

are you planinng to get a bigger turbo anytime soon if you are you might want to get 780's or the 880

With a DSMlink

I imagine he, like most people, will probably upgrade to DSMLink someday, but if he's content right now to stay with s-afc, then he shouldn't really go much higher than the 660cc injectors since from what I've been reading around here, it becomes a real PITA.

If you're going to stay with the s-afc, I wouldn't go higher than 660's. If you plan on getting a bigger turbo at any point, I'd get DSMLink and use that instead of the s-afc and then get 780's or 880's. But if the biggest turbo you are going to run is the 16g, 660's should be good.

660's and a lot of tuning. Or 550's and easy tuning.
