Hi, thanks for all of your responses. I am also building a type IV turbo engine. But I'm told nothing beats displacement. So welding stroking the crank is a bad ideal? I was able to buy a basket case 2.0 engine, I really like the 911 look.

I don't know exactly when I will be able to start the build, but I sure like the look. So back to the bore and stroke. If I stroke the crank and have a company like J&E make the pistons how much of a stroker could I build? What is the largest bore on a case like this? Since I have the crank, having it welded and nitrated and stroke, sounds do-able.
My interest is in going large on the bore and stroke, but again I don't know squat about this case
