Replace oil pump and cooler?

[Dr. JL]

I've got the 3.0L out of my '91 NSX for a rebuild. I'm thinking I should also replace the oil pump and oil cooler. Thoughts? She's got 230,000 miles.

Well oil pump gear was seen failing with track use. Sitting on redline. CT has CNC'ed gears as does Toda. Next time I'm doing TB and LMA upgrade I'll be upgrading oil pump gear too.

Oil pump dissassembled and inspected within tolerances! Good to go for another 230,000 miles!
