I gotta tell ya, the orange 86 I had made a little over 1200 hp. "A" block 363/TFS r/Single 95 mm turbo on straight meth running a mechanical belt driven pump that would pump reservoirs dry in a minute.
I didn't know dick about meth,...and less about tuning with it. The hp numbers came from the previous owner after he lost control of his car with that engine in it, and put it on its roof.
That engine hurt itself as a result of my steep learning curve,..... twice. The first time hurt the head when it went lean, and the next time it took the block with it.
My friends told me that it was part of racing, and you "gotta pay to play". I saw it as a sandbox I couldn't afford to play in.
You gotta have the right attitude after a failure when you're making the power you're making, it seems that you do. But I'll be honest..even after the huge loss I just went through bailing out on the worlds most expensive collection of misfit parts, and now getting set to spend another 5-6k to shift directions..I'm about at the end of my tolerance for breakage.
I hope ( and from what I read, it's feasible) that a 500 hp 2jz is " mild" by other standards, and that it should be able to tolerate that as a goal.
But after its all working right............If something breaks, there'll be a roller for sale immediately afterwards.
