DOOD!
I must interject here.
FYI, a wastegate is the mechanism which allows the exhast gases to bypass the exhast driven impeller in the turbo when the compressor side of the turbo acheives the predetermined boost level.
If you remove it, A, all the exuast gas will bypass the exhuast impeller, and NO BOOST will be made, or B, if you remove the wastegate diaphram. There will be nowhere for the surplus gas to bypass, and either the motor will destroy the pistons, (Quite likely) or (if it's quite worn) the turbo will "expire".
A BOV, is a devise which vents the body of compressed air between the turbo, and the throttle body. This allows the turbo to continue spinning during gear changes, and reduces lag by allowing the turbo to not have to spool up against a body of pressurised air.

I'm not throwing sh1t at your abiltiy to manufacture items of a murchantable quality, but maybe you need to undertake some further research before you attempt to produce something which people are expected to buy.
