Hi
I have turbo'd my 3b. I guess the best extra I did was the 2 1/2 inch exhaust added at the time. I believe that has contributed to more torque in the 1000 to 1500 rev range.
The other things I did was a boost and EGT gauges. I mostly only boost to 5 lb. the gate is set to a max of 7.5 approx. EGT I only let max at 500 then will take foot off the gas.......
I used a Aust kit through the local turbo guy. But lots of ideas and specs on using C26? turbos on
