i am looking to turn my boost up to 10psi and i know that it will cause it to run lean im just wondering where to buy injector and advice on what size to run i think that 600cc primery 750cc seconderys would be good but i want other peoples ideas and maybe what kind of power i would be looking at

 

what kind of car and turbo? How are you controlling the injectors?

 

Get some Hiflow S5 injectors.
I have hiflowed them to 800cc injectors.
They are high impedence and have an excellent spray pattern. much better then most 800cc injector out their.

 

what size turbo? and which car? (FD FC?) Do you just have the stock rails now? What ems are you running?

 

Looks like he's an FC. Honestly 10psi isn't that much so unless it's an upgraded turbo the factory setup would most likely suffice. Normally for low boosted cars or even mid boosted cars you should keep the factory primaries and just upgrade the secondaries to 1680's. You'll retain a good idle and be able to play with the transition.

 

im sorry i have an 87 t2 stock turbo i removed the tmic and just put a pipe in its place it had terrible heat soke issues the only other mod other than that is RB down pipe and hks hi power cat back no cats or resinators what kind of fuel manigment would i be able to use to adjust primery and seconderys seperitley

 

rewire the fuel pump, port the wastegate. 10psi is right at the limit of stock injectors if they have been cleaned.

 

what dose it take to port the wastgate i have looked into it but never heard of any body doing it will it help keep my boost down and not over boost

you should be searching the 2nd gen technical forums for answers to your questions. The single turbo forum is mostly for cars with a much higher level of modification than yours.
