What can I do to rebuild my 1.7 for more HP and torque but keep the original d-jet.
piston and cylinders crank camshaft heads ? I know I can't change the cam too much but is there one that will do better and still work with d-jet. I know there is modern FI but I'm not interested. No carbs. I'm not looking for all out HP or dropping 10K on an engine kit. I just want a nice bump in power, if possible, while keeping a stock looking engine. |
