Moving on from 350Z to a 370Z

Yes, I'd say it had full bolt ons.. the DE engines dont really get much more power from bolt ons though (compared to what I see from here in 370z scene), for me the real game changer for the DE engine was the camshaft and moving the torque curve to peak at around 7000rpm. But even with all those, it is very rare to see 300whp.

And yes, definitely tuned, as it is very necessary when running different cams in the DE mainly because the variable cam timing goes out of wack and you lose power in low and mid range.

Regarding the stock oil cooler, where is it mounted on a 2013 model? I saw this nismo option oil cooler that has the cooler in front of left front wheel with ducting.. looked very neat but $$ for an oil cooler kit What was the max oil temp you saw at the track?

it has a water jacket oil cooler. essentially a water cooled sandwich plate between the engine and oil filter. get a good 25 row and call it a day. they are a pretty easy bolt on and make a HUGE difference. im talking like 30 degrees dd'ing in summer

not worried about moisture in the oil that you cant boil out during your commute?

nope. car doesnt really come out in anything below 45-50 very often. as long as the oil temp gauge gets to within a low operating temp, then i don't worry

looks like its got the same water cooler like the 350Z then, to be honest it did not seem to really cool the engine down much in the old Z, and if you think about it, it is using hot coolant which sits around 100degC, compared to air which is under 30degC and its surface is just too small. In my old Z I put on a small oil cooler first (I think it was 12 row or something) and I was still hitting 150degC (302degF), so I replaced it with 25 row or so and it brought it down to around 130degC (266degF).

I am getting an oil cooler for sure anyway because I cannot see how the car can handle the heat otherwise. Thanks again for the info
