I?m running a KKR280 that I bought from Otomoto. It performs well and delivers decent power, but the internally gated version is too small for my 20v engine. The wastegate can?t expel enough exhaust to regulate the boost pressure, causing boost creep My free-flowing exhaust isn?t the issue; it?s not back pressure. Initially, the turbo was supposed to be set at 9 psi, but it was set to 17 psi, which was unsafe After contacting the seller, they sent a new wastegate that was set to 24 psi. Frustrated with the situation, I eventually installed a CA18 actuator instead.
