IC Piping and injector question...

[bRiAnMcIvIcS]

Im about to order this IC Piping.

It seems pretty cheap and it has the tial bov flange, and bead rolled ends also.
1. Is the piping to small???
Im gonna use a mishimoto Z line intercooler.
Im only looking to get about 220whp with a 50 trim garrett 48. A/R on my B16.
2. Would the blue top 450cc injector be to much? Or would i need 370cc injectors?
3. And then i guess convert to obd1, omni map 3 bar sensor, get a p28 chipped, resistor box, tunning, and walbro fuel pump...Right?
4. Should i invest in a greddy Turbo timer?
5. Would the 50 trim 48 a/r spool pretty fast? around 3000rpms?
I dont care about top end power i got the turbo for low/mid.

What else do you guys recommend? This is my first turbo setup.
