Helping my friend piece together a turbo kit and since this is both of our first times, we're not sure what all we need. I think I have most everything, but just wanted to check.

turbo
manifold
wastegate
downpipe
oil line
get oil pan tapped
intercooler
piping
couplers
clamps
blow off valve
boost controller
turbo timer
FMU
injectors
gaskets

What all did I miss?

Also, it's a stock D16Y8. Running a Greddy 15G-TD04E at 8psi max, what ratio FMU would be needed?
