I have a B20 in my teg and I looking to purchase a turbo kit. I've been searching around and I can't find any information on the difference between a T3-60 and a T3/T4 turbo. If anyone has any info on the difference and which is a better purchase, it would be much appreciated. Also is it bad if I did purchase a T3-60 if I didn't have the money for T3/T4?
