Nismo Thermostat For Rb25det Neo

[Boss-zilla]

Just a little info to add

If your car is over heating on the track, put a higher pressure cap on your radiator (remember little steps!) When you increase the pressure on the water mixed with coolant (only works if there is water and coolant) it incresses the boiling point of the fluid.

Again only do this in little steps because you can have too much pressure then it all goes bang!!!

trk,

BassJunky 'used' to run a high pressure rad cap.

BANG went his radiator or was it a top hose? (can't remember was some time ago) at a Motorkhana I believe. There's a vid floating around some where. I've never seen some one get out of their car so fast to pop the bonnet.

Thanks for the input guys, appreciate it. BUT I STILL NEED A PART NUMBER ! Anyone? Anyone?

Obviously my thermostat isn't working properly (highway temps of 68degC is a joke) so I've gotta replace it. I'm just putting one in that'll get me into a more efficient temp. zone. (most new cars run around 100deg, so I'm not concerned about the 5deg. increase)

As for big-heat, I've been "pulling the plug" on hot-lapping at 111deg.C when the temp gauge starts heading rapidly North. I've seen it hit 113 at Winton, which isn't boiling yet (thankyou coolant & pressure!) but I REALLY don't wanna kill my cylinder head finding out just where it boils, Ya'know? ! ! ! I'm hoping that a new thermostat, and cleaning out the block where it seals will also help reduce max.temps, as it'll reduce water flowing back through the block at full-open (100deg.C+ )

Well changed my thermostat a week ago & ironically, the rubber seal on the thermostat that helps the car normally get up to temperature faster was rooted. My engine has had a weak lot of coolant in it at some stage though & this may have contributed.

Warms up in about 5 - 10 minutes now & no longer have problems with rich & retard on a cold night once it's warmed up properly . So unless u have aftermarket engine management & a highly tuned engine, I wouldn't bother with the lower temp thermostat. Just pouring money down the drain IMO.

Disco,

The PowerFC provides fuel enrichment for anything below 80degree's. As the Powerfc base maps closely reflect that of the std ecu's maps I wouldn't be suprised if the std ecu's values also provided fuel enrichment below 80degree's.

I changed the correction on my PFC so from 50deg to 80deg its the same as +80

as my car sits on about 77-78deg on the freeway....so much better economy now....i just dont rev it untill its gets to more than 65deg (forgies) and even then its a real easy rev.
