I'm creating this thread for a few different reasons. I'd like to get a better idea of how many bad N54s there are out there. Maybe it's my own opinion, but I feel like most people are quiet about blowing up a motor. Whether it's embarrassment or covering a vendor's ass.
For those of you who have, please comment with the following info:
For those of you who have, please comment with the following info:
- Mileage:
- Power:
- Reason:
- Now what?
- Mileage: 120k, tuned since 85k
- Power: ~600-650whp (MMP Stage 3 twins at 28psi with straight E85)
- Reason: Low compression on cylinder #3. Not 100% sure why yet. I was having large ignition drops that I tried chasing down by installing a better intercooler, colder plugs, and the PR ignition upgrade. None of them helped. Eventually it started to misfire on one pull and I still sent it. I'm guessing port injection played a roll in the mess as well. All cylinders were at 170psi, except for #3 was at 70-80psi and went up to 120psi when I added a tablespoon of oil.
- Now what? I'm still deciding. I'd like to find a lower-mileage stock motor to throw back in. Maybe I'll build my current motor over the next couple years.
