did search, but didnt' really find what i want to know

need to know what is the good and bad things about internal and external turob, also internal and external wastegate...any info would help

if i want to turbo a sohc, does the internal or external turbo make any difference?

more question, i know some turbos have both oil and coolant run through them. do most people use those ones? or do most people use those turbo with just oil run through them? is there a big difference between the too kind of turbos?

thx

First, the only thing internal or external is the wastegate. Internal wastegates usually come with the smaller turbos (t28 or t3). External wastegates like Tial are used for larger turbos. For small amounts of boost (5-7psi) I would choose a smaller turbo with an internal wastegate because it will spool up much faster than a larger turbo. But for 10 psi or more....I might go with a t3/t4 with an external Tial wastegate. But that's just me.
