Thank you lol. The best thing you can do is read, read, read, read, read. This platform is the better part of like 6 years old now, every single question has been asked, answered, and beat to death 100+ times.
The best way is going to be to search this forum through google, for example you would type:
"3.7 mustang intake mustangevolution" and it was pull up threads on this forum discussing intakes.
"3.7 mustang gears mustangevolution" to search this site for gear threads... you get the idea. Read, read, read, and when you think you know everything read some more. You will get a lot of opinions on here, and quite frankly that's what most mods are, opinions. There is no "best" anything so it will be up to you to decide what fits your needs.
