I returned the adaptors to CZP. The outlet is also off about 15 degrees-- Z1 cuts off and rewelds the outlets to stock specs. Need to replace the wastegate actuators and fabricate brackets. May need to adjust/reweld the wastegate flapper lever arm. The turbos need to be reclocked, and you need SS oil lines and modify the return lines.
Other than that, they are pretty much a bolt-on deal ;-)
