I'd say google the internet for Oldsmobile parts, then try eBay search, then see if someone on your local craigslist is parting out an Aurora, then try a large wrecking yard in your area, or a "Pick a Part".

With CAI, you have to be careful of how low they place the air intake, since there is the danger of sucking water into the engine from a deep puddle, etc. So placement of the air filter is an important engineering feature for you to investigate. If your engine inhales water from a puddle, it'll seize up in a red hot minute. |

Replying to: cadillacraig (Mar 01, 2009 8:37 pm) If you are willing to do that consideration, you will gain a lot of torque at lower RPM because the 4.0 seems to be a down-stroked twin. You will have to carefully research such things as weight and physical size to see if it is do-able. Any great weight changes would need to be considered with suspension. A heavier, longer through crankshaft would add weight, but partly offset with shorter connecting rods, I'm assuming. They might even use the same heads? But then I would not be surprised if the 4.6 had bigger valves or a different valve timing. Also cooling capabilities need a close look. If you have the one with oil cooler, you might consider a radiator w/o one and a way to mount the current oil cooler in front of radiator. Then learn the intracacies of wiring. There might not be any differences due to the similarity, other than computer programming. That is they may use the same computer, but then there may be differences to programming for non-powertrain items. You could overcome this by knowing someone who has the programming equipment and changing the parameters coded in. Also there is a final drive issue to look at, comparing to the Cadillac with the 4.6. The Aurora came in a autobahn version. As near as I could find, the only differences were the requirement for V rated tires and the final drive ratio was different, allowing more RPM per MPH. It seems the standard setup did not have enough torque or HP to push it 150+MPH. And of course the RPM limiter was either removed or raised to a much higher point. I'm not saying the final drive of the standard Aurora 4.0 is the same as the Cadillac with 4.6, or even the autobahn version. Something to consider and weigh according to your end desire. That is I can't even say if the fuel mix parameters were the same for the autobahn version or if the computer automatically took care of that and certainly something to consider if you start swapping final drive ratio. Good Luck. |

Broken connecting rod. Broken Crankshaft. Damaged cylinder wall. At least damaged bearings. Cold water sucked through intake might yield: Warped or cracked heads. Cracked valves. Cracked block.
