St170 fuel injection on a budget project.

Yeh the ports are around 10mm higher on the st.

The fuel pump should be better for carb upgrades as no return will be needed.

The exhaust is a 4-2-1 design and I know a few have reworked it to fit a kit so no adjusting will be needed.

Yes there is some working out todo, but I enjoy the engine managment side of things.

It will run better all round than any megasquirt can be tuned to do.
