I was reading somewhere that the newer tps was required for proper idle and what not and sure enough it has a different part number. If it doesn't matter oh well at least I have a spare.
Apparently the CHTS and CTS will read the same, which is why most people think they can be interchanged. A cts would probably work in the head since it's a dry hole, chts wont work in a wet hole due to the swivel action.
As far as the oil pump goes, the last thing I want to do is get the car running good only to blow the motor due to oil starvation. I got the higher flow model just for some piece of mind. Now I'm looking at the injectors which I'm sure are from a 280z. Going to have to buy some injectors now!
