I have an 87 tII and was wondering if ill have to make any changes to safely run 110 leaded fuel. theres not to much done to it yet but just want to be safe. it has 3 1/8 exhaust, intake, 720/720 injectors, no emissions, rtec1.8, and a couple other little odds and ends. im also running 12 lbs boost. just dont want to pop the motor or something at the track.

Just run 101, should be more than safe on that, and its still pump.

If is leaded, it will kill your O2 sensor unless you have a heated one. Otherwise is ok.

thanks for the advice

Agree you don't need anymore than 100...any leaded will kill o2 sensors and cats.

i wanted to run 100 unleaded. so it is safe to run it on a basically stock TII?
