Default Torco or not?

Hi guys,

I'm wondering if running Torco on my EJ20K will have any negative effects? Or even if I will see good results?

My basic concern is the low octane gas I get here in Costa Rica (91 tops) and I want to avoid knocking, specially during track days...

Engine is absolutely stock! Not even more boost or any other change....

Can I use Torco as DD? I've heard Torco damages catalyc converters and O2 sensors...

If only used for track days, would I get good results? What would be the best "formula" of gas/torco?

Thanks!!!

you can use leaded gas without any issues other than the front 02 sensor will die quickly because of lead's impact on zirconium

I'm curious what the octane of a bottle of Torco is.

I had a crazy idea of putting lacquer thinner with a couple ounces of power steering fluid.

I don't detonate anymore at max boost. Would I do it again? No.

I don't have any input on fuel additives, but have you ever thought about getting a water/meth injection system? I would think that would be your best bet at combating high EGT's and knock, and if you do track the car or drive it hard often, it would be that nice insurance against any premature engine damage.

Thanks,
Rick
