I wanted to start a poll on the longevity of modified FDs. This will give everyone some ideas as to the range of miles they can expect from modifying their engine.


Please answer the poll if your car has been modified to >400 whp.

 

I'm at about 10k miles on this motor. The water injection should help with longevity

 

U should have people say if they tuned it themself, or had it tuned professionally also.
