Thermostat compatability confirmation

[DrMango]

Does anyone know for sure if a Z31-Z32 thermostat will be compatable with RBs? I was told they are the same for the following but not sure if I can trust them

RB20DE, RB20DET
RB25DE, RB25DET
RB26DETT
VG20E, VG20ET
VG30E, VG30ET
VG33E
VG30DE, VG30DET, VG30DETT

I used a 1996 nissan pathfinder one
forget the number

used p/n 21200 42L06 – thermostat for RB26 order from any nissan dealer

I needed the compatable one so I can order the NISMO unit. Im sure that P/N is for the OEM?

Nismo thermostat is a bad idea. An engine needs heat to run and fire properly.

[DrMango]

Oh damn. I was just reading all the sales points on them and they said a NISMO unit will allow you engine to run better and for a longer period of time.. must not listen to salesmen... lol
Would there ever be an advantage to a NISMO unit?

Will just get a new OEM then..
Thanks guys

I think Mcfly is referring to to issues surrounding cold enrichment. The nismo thermostat doesn't let the oem ecu see that the engine has "warmed up" and will always be adding a bit more fuel to the mix.

maybe that's why he said that

[DrMango]

Its getting a a Nistune setup shortly after the engine is back together(after break in) so would I be able to tune the Nistune for the NISMO thermostat to work properly with my engine setup?

With what rb racer said, that is correct.

My justification is that formula 1 cars don't run below 80c,

[DrMango]

Thanks then guys I'll just order the OEM one that you mentioned before
