Ok, I am a tubro noob. I know a little about turbo's just not a ton. I am looking to do a single turbo setup and run about 7 psi max on my truck. I was gonna go ahead and purchase a turbo but dont know what style or anything I should look for. I know there are internal and external wastegated turbos. Which would be better?


I found a turbo setup with these specs:

-Compressor Wheel Major Dia 76.2


-Compressor Wheel Minor Dia 56.5


-Compressor Trim 54.98


-Exhaust Wheel Major dia 66.3


-Exhaust Wheel Minor dia 56.3


-Exhaust Trim 72.11


-Compressor AR .50


-Turbine AR . 63


- 38mm External Wastegate Setup


Does that seem like a decent sized turbo? I dont really know the difference in the trim and all that good stuff. With the internal or external wastegate, can I run an electric boost controller on either or is the internal one set at a certain psi and same with the external? All turbo info would be very much appreciated and returned w/ +13
