what should i expect to pay?

[Turbo Habanero]

So im looking to upgrade to the lexus AFM/550 setup on avg what should i expect to pay for injectors?

I also see people with 560s or 540s how big of a deal is it to be 10cc off?

i know i also need or should have a upgraded fuel pump/afpr and something to tune with (Apexi Safc) is what i will more then likely use for that not sure why but i see them on craigslist and here alot for pretty cheap.

Mods at the moment are Driftmotion Intercooler 2.5 inch piping all the way to throttle body. driftmotion 3 inch Downpipe (got rid of elbow) and custom catless 3inch piping/intake filter.

Depends on how big a deal. On avg. 250-600. 600 being new.

540 and 560 are ok to use also.

I paid 350 for my RCs, they were used but were cleaned and flow tested before I bought them. I think that is a must if you are purchasing used injectors. You should definitely get a bigger fuel pump, but the SAFC can be bought later on. When I was using the AFM and 550 mod, I didnt buy a SAFC for a couple months later, and the car will run fine. Once you get the SAFC, you can put it on the dyno and adjust where necessary, because the car will be running a little rich.

i would highly suggest a wideband afr gauge. when your messing with anything tunning related its always a good idea to monitor air/fuel ratios.

I agree; however, I would always prefer tuning on a dyno instead of doing WOT runs on the street. Much safer...

I have a wideband and the Haltech to log runs on the street, but I rarely do any logging on the street because even on the highway, Ive had some close calls. Ill stick to the dyno...

Mitsu evo 560 injectors are cheap, perform well and reliable (since they are oem) I got my set for I think 270 shipped from a member here.
