dean_asla Posted November 9, 2020 Share Posted November 9, 2020 I recently bought a 2007 350z Nismo over here in Japan, it started to have issues between 1500-3000revs when cold where it would shudder, then after 3-5 minutes would be fine. Car is under warranty but they don't seem to know/want to fix it, research points to VTC issue. Anyway they have told me they will replace the engine, I have lots of concerns about this, unknown mileage etc but is the Nismo HR engine exactly the same as a non-Nismo 350? I want to ensure they put exactly the same engine inside if they do replace it. Also would the 370z engine drop straight in, or even a 380RS engine?

Olly350z Posted November 9, 2020 Share Posted November 9, 2020 Im still putting money on gallery gaskets being your issue. The shuddering is a well known result of low oil pressure not reaching the top of the engine. Quote Link to comment Share on other sites More sharing options...

They have found a 90k engine which they are going to fit and give me a 3 month warranty on, This is the only option I have, it seems there is very little rights for someone who buys a 2nd hand car in Japan and I have no choice but to take this option. Would have preferred them just to give me the money back, that also wasn't an option for them. Quote Link to comment Share on other sites More sharing options...
