scturbo28

Hello community i was wondering since i am going to start doing upgrades little by little i just wanted to know a couple things . I have a sc 300 with a 1jzgte-vvti and i was wondering how much boost i can run on the stock turbo.i think these engines come with a ct20, correct me if i am wrong . Also i know these turbos come with ceramic blades so they are not that efficient . i will be runnning the stock turbo for a lil bit so i wanted to get an idea of how much boost i can run on my turbo. The car is completely stock except for 3inch full exhaust system and an air filter , other than that its stock. thank you very much, also what boost controller would be good with this application. I am looking for a boost controller thats accurate , user friendly, and not hard to program and or understand at the same time.
