xtremeleo say it the best!!....
a bigger oil cooler also will cool down ALOT of oil temp and eventually cool down the water temp so the engine will not be in the 80-90 degree optimum temp..
but this 80-90 only work with NA engine.Not too sure about turbo :)
bro GT20V : thanx a bunch bro :)
as i said, the thermo thingy is fitted to regulate temp to a certain value, the engine's optimum operating temperature. so, it is there for a good reason. overheating is caused by other problems and thermo is just a factor to consider. if u experience overheating, and suspect dat d thermostat is d culprit, den a simple check up wud be sufficient enuff. let the engine idle until the radiator fan kicks in. if it doesnt, den check all the relays, fuses, wirings, etc. if all is okie, den check the thermostat if its doing its job rite. if if can do the job, but not in the rite temperature, den a simple adjustment is what u have to do, or just replace it wit a new one. other den dat, leakage, radiator cap fails, coolant level, etc.
as GT20V said, an oil cooler wud be benificial for engine cooling especially for a high revving engine as the 4AGE 20V. but, one thing to take into consideration is the oil pump pressure. fitting one (edited) of this unit will drop d pressure across the oil lines. so, increasing the oil pump pressure is supposed to be done wit dis cooler installation. oil pressure is very crucial for a charged engine because if oil starvation happens, even though only in seconds, the turbine mite fail. for an NA, iam sure u dont want oil starvation to happen whenever u high revv the engine. FYI, oil starvation can happen to all moving parts ie bearings, piston rings, etc.
almost all engine have similar operating temp, just dat a charged engine needs to be cooled faster den NA because of the heat generated by the turbine. sport thermostat actually lets ur engine runs a lil bit cooler from factory setting, so dat ur engine cools down faster. fitting a sport thermo into a road car isnt a very good idea, imo. its to improve the cooling time in a race engine, which is alwiz high revved in races and generate more (not higher, if the temp is controlled) heat den street engines.
