I was wondering if anyone could tell me if thermostats with different part numbers are perfectly interchangable as it doesn't make sense to me why Nissan would make different part numbers for the exact same item 

 

Specifically I am chasing a thermo for my rb25det neo part# 21200-V7205 or 21200-V7206 and I have found a seller with a part# 21200V720A suit patrol GQ/GC and he tells me they're the exact same and interchangable (they have the same operating temperature too). I would just buy the correct part# but the 21200V720A is nearly half the price and is a genuine Nissan item 

 

Can anyone please shed some light ?

Nissan changes the part numbers all the time because they change suppliers, they make minor revisions to cut cost or whatever reason. If you look up the 21200-V720A in the US parts catalogs they list that part as the superceding part number for 21200-V7206: https://www.nissanpartsdeal.com/parts/nissan-thermostat-asmy~21200-v720a.html

Same goes for Amayama actually, looking up both of those part numbers they list the V720A as the superceding part: https://www.amayama.com/en/part/nissan/21200v7206 and https://www.amayama.com/en/part/nissan/21200v7205

I have gotten a bad superceding part number from Amayama before with a replacement hose clamp not being the correct type to fit but I've yet to see any issues with the Nissan USA parts catalogs, those seem to be standardized a lot better. I have a lot of weird obsessions but I have never seen any reason to go for NOS of older part numbers, in my experience the OEMs care enough about supply chain integrity that I don't have to worry about it.

      The R32 suffers from an instrument binnacle that is uncomfortably close to the design of a VN Commodore's. But beyond that, the layout of the rest of everything, and the materials (ie the vinyl coverings on dash, armrest, etc) are acceptable, and the patterns on the fabrics are not as blergh as those in the R33. And R33 seats are....quite unattractive. I know it's only small details there, but I reckon the R33 got worse than the 32. But the big blergh is the overall shape of the dash on the R33. It's just has that whole Maxima/Pulsar sort of look to it. Nothing special at all. Generic Nissan sedan. Whereas, at least the R32 dash/binnacle was different. Less a wide expanse of boringly curved plastic. More a "cockpit" sort of look, even if nowhere near to the degree that the A90 Supras got. R34 seats look good on their own, until you realise that they are indistinguishable from the shape and fabric on 70 other Japanese cars. And the foam bolsters on them suffer even worse than the earlier cars. Other than that I don't really have an opinion the rest of the R34 interior. I took the bits of the R34 I wanted (brakes and engine) and added them to the best external appearance Skyline in the modern era (the 32). So nyerr!

      Can I be your first customer? I would like hard lines done for the fuel system, 8AN up and 8AN back and the underside wire wheeled and coated (brush or sprayed) with that black tar shit.

      Speak for yourself, I love the R33 interior. 32 is blergh. I like the 34 interior too. Then you start getting much newer in most cars and they all turn back to blergh. 馃槢

      500-600hp into a RB is already 'sinking endless amounts of money' into an engine. Especially a 30 year old engine. Unfortunately this is the RB Game. Considering stock power (or at least stock components) will do ~360whp on 98 by simply turning up the boost on the stock gear on a RB26, that would be where I'd say the cutoff point for "sinking endless amounts of money into the engine" Cause to even do this reliably you'd probably need to replace all the bits anyway cause they're old, starting your sinking journey anyway. I reckon the least painful way is rebuilding the engine to make 50hp over stock lol. The 'plan your ownership around a rebuild' was a common saying 15 years ago.
