So, i am finally getting my honda civic b20 turbo'ed. I have everything ready for it except for a Tune.
Mod:
Stg 3 clutch
Lighten flywheel
Cams (402)
Revhard exhaust manifold
Revhard inter cooler
Ebay turbo (JDM SPORT)
and unknown piping Bov and ext w/g (6lb for now)
550 RC injectors
Walbro fuel pump 250
stock p72 ECU
Manuel boost controller
i was wonder if i can drive my car for awhile like this without a tune just completely stock. Any advance would help dont want to blow it.

NO. You're exponentially changing the amount of air with no fuel control without tuning. You will destroy the engine. Tow it to the tuner, or run w/ one compressor pipe disconnected to the tuner. that's it.

the only way to run somewhat safely is you can get an adjustable fuel pressure regulator and increase the fuel

^ I don't think the car will even run right.
Get a basemap, drive it to the tuner's w/o going into boost.
Or tow it there.

turbo will spin too quickly

No. the turbo will not spin too quickly. the reason for disconnecting the charge pipe is so that the turbo will only reach the engine's exhaust velocity only under vaccum (0 psi on the gauge). The only time spinning too quickly is a problem is a Sudden change of pressure from say 20psi to 0. An example is if an I/C pipe pops off suddenly during a dyno run at higher boost.

Done it for 10 years.. its ok.

I def would not risk it. I got a basemap mailed to me to be able to drive it to the tuner's place. Safest way besides towing it, you got the money for all that setup what another 40 50 bucks?
