Hey All,
So I am in the process of making my 400 N/ABHP 1GR-FE T4R a mere 450-500HP and of course that involves tuning. I know old time tuning methods but computers and tables are all so new to me. I was messing around with the base ignition table, as well as the intake and exhaust valve angles and actually made a somewhat small but decent crackle tune for it. I started thinking about my poor heads and then I realized I could just look up all of these Toyota Engine Specifications.
Long Story Short, There isn't jack on what the 1GR-FE is Capable of, especially in terms of the 4Runners models. I want to know if anyone has any sources for the real deal test of these engines. I know Toyota has a habit of randomly picking off an engine from the conveyer belt and redlining it for an hour or 2 above what it's normal redline is, but I can't even find any information on that? I want to know what Toyota has truly pushed this engine to do on the stock internals and variables (Obviously I don't have stock internals) but it is an ok reference. Any information would be amazing!
