Injector ??

[mhopemk3]

I am going to replace th head gasket (metal) and have the head rebuilt in the next couple of weeks. I want to install a Walbro, FPR and larger injectors. I will most likely be purchasing the Maft Pro full setup as well. Still running stock CT unless I get the group buy upgrade.

The question I have is what size injectors?? I know alot are using 550's.
If I upgrade the CT would I need more fuel like 680's or would that be too much??

680 is over kill

550 support to around 500 rwhp.

agreed. 550s is fine for at least 75% of the people on these boards and unless you are going over 500rwhp its not needed to go bigger.

OK 550's.. I do plan to go over 500 but not until possibly next year after the internals are upgraded.. I just wasn't sure if it would be smarter to buy a little bigger now... I can just sell the 550's when I move up..
