Rebuilding Happiness

If we have to rebuild -  let’s make it stronger

If I had to work from the bottom up again I decided to do some research and find out what the strengths and weaknesses are of the Buick Regal Grand National, 3.8 SFI, Intercooled and turbocharged engine. I learned that these blocks had a weakness in oil circulation. What can we do in the new engine build to improve on oil circulation? We purchased a block and had custom machine work done to improve oil flow. Here are the basic specifications we built the new engine on.

• 43lb. Fuel injectors
• High volume oil pump
• High volume fuel pump
• 200 Amp alternator
• Block machined .030 over
• Three and a half inch turbo down pipe
• Three and a half inch exhaust system
• All new copper wiring in engine
• Extra oil galleries added
• Chrome moly rings
• Aluminum pistons

Added Interior Gauges

With a freshly built engine the standard gauges built into the dashboard were not enough for me. I had to get some real gauges that would let me see more about what the engine is doing.

Seeing the turbocharger performing and watching your knock sensor are great improvements. The knock sensor helps protect against the number one killer of this engine; detonation. I also want to keep a closer eye on oil pressure and water temperature. To do this I will get gauges we can install on the dashboard console.
