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.

1. no 2.25 in piping is fine. i dont see why that piping wouldnt be good as long as its bead rolled at the tip so your couplers don't blow off..
2.450cc just in case you turn boost up or whatever
3.yes that's the same setup i have works great going strong on 7 months
4. turbo timer would be more convenient than waiting in the car for the turbo to get cooled down. so yes.
5.i think so, maybe some other turbo heads will chime in.

what are you tuning your car with?
