550cc injectors in a GTR???

[lazza]

Is it worth getting 550cc injectors as an upgrade, or should I be looking at 700cc injectors? I have N1 turbos and the usual exhaust / boost modifications.

The standard injectors are maxing at 272rwkw in non shootout mode. What's the maximum rwkw could I expect from 550cc injectors?

Thanks!

go the 700cc not worth doing the upgrade twice and i believe there a car in wa wish they had put 700cc instead of 550cc ouch. If your running a pfc its not a problem to control at low % as my runs sweet as on them. Can also stop you from having buy a bigger pump to have to push the higher pressure to try and get the hp needed, my std pump and 700cc with pfc making 525rwhp cant complain with that?(out of std pump)

same just go the 700,if its worth doing, its worth doing it right!

i've got the 700cc and we've got 290KW at all four.

Same again, i have 700cc Sard's and considering the negligible price difference between the various sized injectors these days, the 700's are a much more attractive option than 550's particularly if you are planning further engine work in the future.

Thanks for your opinions guys. I have a rechipped stock ecu to suit the N1 turbos, Im guessing I will have to upgrade this to run 700cc injectors?

yes, you will need either a re-map or something programable. at the price it's hard to go past a PFC. as mentioned earlier they will have no trouble controlling your new injectors.
