SInce the stock sr turbos can go up to 15 lb, what turbo would be an apgrade, in a way that you can run 15lb safely ( on stock injectors??)
I know this may sound stupid

 

t3/t4 turbo? im not big on turbos

 

WHat do I need in order to run 15lb safely?

 

daily driven 15 lbs........my guess is on a stock motor you wont be efficient. Now, upgrading your injectors, fuel pump, intercooler, etc, these will help you run "safer", as well as more efficient.

 

the car i am planning to buy, already has a blacktop, BLitz FMIC, full exhaust, intake, bov, boost controler, racing clutch, and upgraded fuel pump. He is runing 13lb on stock turbo, I want to get a better turbo which would be more efficient, and aithout pushing it safely run 15lb.

 

you can run it fine. You wont need any upgrades except for a boost controller

 

...............and a FMIC
