2006 Mazda RX-8 — engine fits but driveline angle is not ideal

FlatSixDailyCommunity StarterMay 13, 20262006 Mazda RX-8 SportBay Area
2006 Mazda RX-8 Sport, about 219,000 miles. Mock-up clears the steering and firewall, but getting the transmission output lined up perfectly would require moving the engine. How much should packaging be compromised to improve driveline geometry?

Write down what you already tried. A second data point from another 2006 Mazda RX-8 owner helps more than a generic diagnosis. Then you'll know the next fork. A shop burned me once by skipping that step. Not trying to scare you — just skip the expensive first guess. This is the version I'd tell a friend.

Useful. I'll report back after I verify that on my 2006 Mazda RX-8. Might be overthinking it, but I'd rather overthink than overspend.

Owner notes beat generic advice here. On the 2006 Mazda RX-8 in Bay Area, I'd fix the thing you'll notice every day before chasing spec-sheet extras. Then you'll know the next fork. On “8 — engine fits but driveline angle,” that was the fork that mattered for me. A shop burned me once by skipping that step. I'd rather look cautious in this thread than stuck later.

I parked the 2006 Mazda RX-8 and wrote down what I already tested so I'm not repeating myself. I'll update if anything new shows up.
