OK - This is regarding the intake swap on my 2004 truck, from 78mm DBW TB & truck intake to a 2006 GTO 90mm DBW TB & intake. I have read the swap topics, but have some questions:
1. I have seen two different links for TB harness adapters (one that is $50 from Katech, one that is $210 from Torque Rush Performance) Which one will work for me?
2. Katech has the injector swap kit to run LS1 style injectors (orings and spacers). I have 60lb injectors now that required spacers on my truck intake. Will the Katech kit work with the 60lb injectors?

Anything else I need? I think DBTBSS will help me make an adapter intake tube so we can reuse the water pump and not have to make or relocate the idler bracket. I can bend the coolant crossover tube if needed.

Thanks,
S.C.
