Turbonetics Evolution & DeltaGate II 38mm Wastegates
I have a pair of lightly used Turbonetics Wastegates:
I will sell them for $150 a piece or trade for one like new 38mm Tial. I've been using Turbonetics since day one with all of my builds but would like to try something different. The Deltagate is currently running on a setup and the Evolution was just removed from a setup and is being stored in a sealed container.
First one is a Turbonetics DeltaGate Mark II Dual dumptube w/ block off for single tube usage:
Designed for durability, with a 1.250 stainless steel valve, nomex/silicone diaphragm and with a unique stand- off actuator section, the DELTAGATE can control boost on engines that develop 350-400 HP. With the addition of a Variable Boost Control Regulator (PN 10402) the DELTAGATE is fully adjustable over a wide boost range.

Second is a Turbonetics Evolution 38mm wastegate with a 9psi spring:
The new Turbonetics Evolution redefines performance for externally mounted boost control. Utilizing the latest technology in flow design and materials, the Evolution features an investment cast 304 stainless body (designed with computer flow analysis), Nitronic 60 stainless steel one-piece valve, rolling type diaphragm and polished aluminum cap. Nearly 25% smaller than the DELTAGATE it is sized to fit into the tightest turbo systems. Fitted with a rolling type diaphragm and floating valve seat it is equipped to comfortably handle 400+ HP and out flows the competition by almost 20%.
