2017 Porsche 911 Carrera S — question: Engine swap packaging: offset versus driveline angle

TurboCommuter28Community StarterSep 2, 20262017 Porsche 911 Carrera SNationwide
2017 Porsche 911 Carrera S, about 37,000 miles. Mocking up an engine/transmission in a chassis with very tight steering and footwell clearance. I can offset it slightly, but I don't want to create driveline vibration. What measurements should be locked down before making mounts? If I fix it I'll come back and update the thread.

Don't overfit one forum story to your car. If it still isn't clear on the 2017 Porsche 911, a specialist hour can be cheaper than another round of parts. I'd do that before spending real money. Learned this the expensive way on a previous car. I'm in no rush to be a hero on it.

Owner notes beat generic advice here. On the 2017 Porsche 911 in Nationwide, I'd fix the thing you'll notice every day before chasing spec-sheet extras. I'd do that before spending real money. On “question: engine swap packaging: offset versus driveline,” that was the fork that mattered for me. If they can't show the line item, I assume it's hiding. If your situation is the opposite, ignore me. That's my plan before I call anyone.

Write down what you already tried. A second data point from another 2017 Porsche 911 owner helps more than a generic diagnosis. That's where I'd start. This is from a 2017 Porsche 911 in Nationwide with 37,000 miles. Do that first. I'd rather be boring and correct. Might be overthinking it, but I'd rather overthink than overspend.

On “question: engine swap packaging: offset versus driveline,” that was the fork that mattered for me. Had a similar mess a couple years ago and that's what finally sorted it. This is the filter I use when the thread starts repeating itself. Wrote this up on my lunch break.

Fair point. Counterpoint: Verify the cheap/easy branch on the 2017 Porsche 911 before a big repair or a big spend. That's where I'd start. This is from a 2017 Porsche 911 in Nationwide with 37,000 miles. Had a similar mess a couple years ago and that's what finally sorted it. Your commute and mine probably aren't the same, but the test still applies. This is me being the wet blanket on purpose.

I'd keep this practical. Verify the cheap/easy branch on the 2017 Porsche 911 before a big repair or a big spend. I'd do that before spending real money. I'd want that in writing, not as a promise. This is me being the wet blanket on purpose.

Thanks — that narrowed it. I'm going to try the simpler check on the 2017 Porsche 911 first. Might be overthinking it, but I'd rather overthink than overspend.
