I've heard of some dealers being able to do the Nismo oil cooler install, but I was wondering about the Bay Area in particular. If a non-dealer can do it, I would consider going with the Z1 25-row instead. Key part is weekends, and reputable work. I know I can't expect the cheapest price around since I assume my choices are limited.
