Is my oil cooler overkill for the street?

I agree. VQ pumps have been notorious for failure. But our VHR's 7500rpm redline was enough to grenade the classic DE pump. So we are better off than the VQ was around 2003. I believe that the VR38 took the pump off the crank and put it down on a chain. But, the Toyota 2JZ seemed to have no problems with the oil pump drive gear interfacing directly on the crankshaft... so there is hope in working with it.

I have a 19-row oil cooler, and when I first installed it, I suffered extremely long oil warm-up times. I like to see at least 180°F on my oil temp's before I shut her off again because I want to make sure that any water residue from the internal combustion reaction that made it into the oil is evaporated out and not remain in the sump contaminating it. My solution was to place a thin aluminum plate as an air-barrier on the front of the cooler blocking off all but 4-5 rows on top. I secured it with industrial strength double stick tape to hold it in place.

Even now, during winter time in 40-ish degree weather, my commute to work (9 mile trip) I am barely at 180°F even though I'm driving in traffic conditions with a few lights. During the summer, with 80/90°F temps, it still takes about 5-8 minutes before temps reach 180, and then stabilize around 200°F under normal driving conditions. Under spirited driving, oil temps climb to 210 - 220°F depending on ambient temp and how hard I'm pushing, but cool off relatively quickly afterwards when I return to normal driving (steady speed, no hard acceleration).

Hope this helps in better understanding what you might want to do.

What size Oil Cooler do you guys recommend for DD and Spirited/Weekend Tracking? A friend of mine had a 25 Row and told me it was good for DD but that his Temps hit 240 after a few rounds at the track. Would a 34 Row be more suffice?

Don't get me wrong, I trust the hoses and fittings knowing they are Stillen and they won't blow apart on the road somewhere, I just wish they had an option for the thermo-plate...

My guess is that somehow you got the non-thermostatic plate. 18 miles is way too long. I'd contact the vendor and ask them what's going on.
