Default Wastegates,BOV and injectors needed for twin 67 LQ4 build....What ones?

I am using stock ECU from a 2007 silverado classic and e-85. My goal is to run in the 8's. Holley hi-ram,102mmTB,twin 6667's,L92's,LS9 gaskets and ARP bolts.

What wastegates and BOV do most run and whose 120# injectors??
I need to buy ASAP as the car has to be running and racing in 4 weeks.

I would run Precision 46mm gates and a Tial 50 bov with 160lb hi impedence injectors from Fuel Injector Connection.

Sounds like exactly what I was thinking also. I bought a Tial 50mm tonight and will order the other stuff tomorrow. Thanks for the reassurance.

Would a 160# injector support straight M5 methanol if I wanted to run it also?
(Goal is mid-high 8's @ 3500#)

You can run two TiAL 38s, they're cheaper. It's what I'm running.

Wastegate's are all about placement. Im always a fan of overkill on the size but as mentioned above 38's will work if placed correctly. Even a single 38 will work if boost is high enough.
