Hi, i started building my custom turbo kit for my 04 lancer es and there is some things i don't have answers to...im going to be using a 16g6 td05hr 9.8t evo 8 turbo. I was wondering how much psi is the spring on the stock wastegate? Iv heard from different people it was 9..some say 11...some 14 psi. And i was wondering how high octane fuel i need to use on a stock internals setup at 9 psi of boost. Trying to have everything setup and ready before i start the engine and tune it. Thanks, Alex
