noob question, is there any point in changing fan switch and thermostat???
no, not on a stock to mild vehicle,they work quite effectively from the factory,honda aint stupid
cool thanks
wat exactly are they for??
quite simply to lower the working heat range of the motor.
honda have already setup the working range of the motor,to where it is most efficient at the factory.
its not until u start heavily modifying your motor or doing extensive high rpm track work,that u will need to address this issue.
i agree... as i have them both and it got the car running a little cooler and as others have said in other threads, it may actually be forcing the ecu into cold idle mixtures and running rich.Quote:

are these mods together at least justifiable if say the CR was at ~12:1?Quote:

im n00b ron,ud have to ask someone that works on modified engines what they have been experiencing for that one.Quote:

But combined with lots of other mods , and on the track for many laps at a time perhaps there is a benefit. otherwise , as said no stick with OEM parts.
i'd imagine u'd experience some overtemp conditions from the higher combustion pressures,but how much & whether the stock system is capable of controlling it,i wouldnt have a clue
no one here would..but from my browsing honda-tech for years i have never ever heard of a OEM honda cooling system fail or let down a worked engine.
As above. As long as the radiator, thermostat, fan switch all working then overheating shouldn't be a problem.Quote:

thats a stock engine with D16 cooling components,running a B18C(also stock cooling components) in a rather cramped engine compartment,there is an oil cooler but i really dont know how effective that is.
so i'd hate to go lowering my temps even further.
