Not yet - still on the stock pump and oil pan. Honestly, I beat the crap out of this thing on the track and it has close to 250k on the motor. Not a single hiccup. These motors can take a beating.You don't have a type-s oil pump do you? 7,800 is my redline as well and I don't think I'd be super comfortable thrashing it at or above 8k without the type-s oil pump. Next mod?
I plan to find a K20 longblock to strip down and use the head, oil cooler, oil pan and oil pump for a little refresh. It becomes a slippery slope at that point so we'll see what happens.
