fuel injector question
 
Hey i am upgrading my turbo slighty and i got a walbro fuel pump and a few more little bolt ons. What size injectors will i need to upgrade to? If any upgrade at all. thanks

Well, without having provided any real information all people can do is guess...

Standard upgrade is 720CC secondaries with an S-AFC to control them.

it is this upgrade http://www.rx7store.net/index.asp?Pa...ROD&ProdID=729 I also do have a safc fcd racing beat full exhuast. So the 720cc secondaries is a good enough upgrade?

680CC primary, 720 secondary should do, with a margin of safety. You'll definitly need that S-AFC, and an upgraded fuel pump as well.
