ID (injector dynamic) make really good injectors.
You're going to need to save a lot for a turbo setup if you want it to be worth your while.
There's TONS of threads on turbo builds and such, browse around man!
Some stuff to consider:
Sleeving the block
Fully built head
Fully built block
fuel pump definitely, dont really need a new fuel rail, I'm still running stock one at 400hp
Turbo itself
turbo manifold
oil feed line, oil return line
vacuum hosing for wastegate/turbo/BOV
wastegate + dump tube
BOV
downpipe
charge piping
Front mount intercooler with all couplings and such
Engine management such as Hondata s300 along with the ECU
A reputable tuner, do NOT overlook this. Tuning literally will make or BREAK a build.
There's always a lot more stuff that comes up along the way, but those are some of the big things to consider. You can have a downpipe and charge piping custom made if you want, as some kits don't fit properly anyway. Stay away from cheap ebay stuff, some people say it lasts, but usually it's garbage.
Always remember, you can only pick TWO: cheap, reliable, fast
