External Wastegate Size and Placement

I'm about to drop the motor into my truck.
I'm looking to build 50-60 PSI with my modded H2E and 300/200's.
In the future I will be adding a 150-300hp shot of nitrous.

What size wastgates should I purchase?
I was thinking of running 2 wastgates, one in each up-pipe right before the turbo.

Thanks guys for all of your help!

Andrew

I wouldn't say that at all! I would just say that I spend my money recklessly...

Thanks for the response. I will check out the army and see if anyone there can offer some help! Thanks!

wastegates arent easy to fit in an obs. it will require some firewall modifications and most guys mount them in a ballance tube right behind the turbo and requires lots of cowl modifications.

most obs guys use a aftermarket high pressure back pressure sensor and monitor back pressures heavily thru custom tunning.

Just a little update. I went with a turbosmart 45mm wastegate. I had a local header shop weld the wastegate flange onto the top of the cast steel t4i manifold.



To get the wastegate to fit behind the turbo I had to replace the body mount bushings and remove a section of the factory heat shield material to prevent rubbing.

I miss driving my truck.. So far this has been an 8 month long build. Doing this stuff is really time consuming and burns a huge hole in your wallet. I just keep telling myself that this will be worth it when it's all done!
