5. Forged Engine Install
Removal Out with the old, in with the new. The motor I had in this car prior to the forged engine build blew a ring land off piston 2 years earlier….
In 2020 I began building a forged piston and rod engine. The engine I had been saving since 2008 from a car I scrapped. The goal was a moderate build that focused more on reliability then ultimate achievable power.
For context its my personal opinion is many builders will get lost in the weeds doing everything that is possible to change a motor to create power or be more theoretically efficient. This drastically increases the cost of the build, delays build time and changes dynamics of the engine that are not easily accommodated for. For example in the past Ive seen stroker builds that would not stop overheating. Engines with tall cams that could not maintain idle properly and builds that spin bearings.
For moderation I choose to lower the compression of the engine to better suit boost. Instead of retarding the timing aggressively and running over 91 octane gas I could increase the boost and maintain MPG while having a wide margin of safely tuning the engine on my own.
