rb25det getting hot.

[ch1873857]

my last rb25 overheated a lot. most of my water jackets and coolant pipes were rusted out. coolant looked like mud. i have also heard that n1 pumps are no good for daily driving. guess i would recommend a stock water pump . make sure your coolant looks like coolant. and most importantly, make sure your system is bled properly. obviously if you have heat that shouldnt be an issue. if you can get some kind of fan shroud and coolant ducting (those cheap sheet metal shits will do) . an oil cooler will not solve your problem. i believe your overheating simply because there is not enough air flow. a proper fan shroud would probably do wonders for you. i plan to fabricate some brackets that set my core further away from the engine to provide more room for puller fans and an aluminum shroud and will cut back on heatsoak.

Oh yeah I know what you mean. My coolant was rusty for awhile,that's why I flushed it so much. That is exactly what im thinking and know. When I removed my bumper cover and drove it,temps dropped from 100c to 70c after driving. I think the kouki front would help a lot with proper ducting and a fan shroud.
