Because you'll need to be pushing about 600-700whp before you need anything bigger than 550cc. There's just no point, and it has the potential to be a problem. And any slight variances in your engine's metering systems (TPS, MAF, CTS, etc) will cause a worse throw off with 850cc injectors.Kenrik wrote:Not if you can get them cheap I have seen them for the same price or even a little less then 550cc injectors (used) so why not be overkill if it makes it so you don't have to change them twice? I am planing on going turbo and really pusing it at some point so it makes sence for me...
