Rb20 Turbo questions and few other

[sonny1335]

is anyone running a PT5857? how do you guys like it? i think I'm about to order here tonight, just would like some input on it. I like it cause its not big and from what other people are saying it spools pretty fast. How big of injectors do you guys think i should run with that turbo and a nistune? I'm really trying to hit 330hp, but in not sure on how many pounds i could be running at safely. On another note way of topic, i live in iowa and its like 47 degrees right now (just got done driving). I took off my front bumper because my new one is coming in tomorrow. I noticed that i was driving around for at least an hour or more and my temperature didn't go over 165. On the highway its like 160ish and on the streets is somewhere around 165? I didn't really notice it till today but last week when i had my bumper on it was like 180-185 and it was warmer out like 65 70 degrees. Just wanted to know if thats normal or too low of a temp. Thanks in Advance guys
