you will be fine with the stock injectors. I have basically all the same mods minus the bov and things like that. Just different company and run fairly high boost. My idc% are in the low 90s

 

I have a IX and with intake, exhaust, intercooler piping, fuel pump and mbc set at 24 psi on pump, I was in the high 90% range for my IDC. I would suggest installing them around the time you install the cams, since they make a considerable difference in air flow, or with the intake and exhaust manifolds.

 

If I would decide to get them, what size do I need?

 

im also wondering when is a good time to upgrade injectors and what size....

 

on an Evo8, stock injectors are fine and are capable of matching all that the stock turbo will flow, regardless of other modifications. Looks like you have quite a few BR parts, what do they say?

 

you should be good with the stock injectors

 

The only mods i have so far are the stage 1 mods, I only have the BR Filter kit as of now, and Im going to Buschurs on Friday to talk to them. Just wanted some opinions on the injectors. Thanks for your help, glad I dont really need to spend another $300 that I was looking at since I dont need them!
