Hell yes! :tup:

Glad you got it back on the track. What happened to the old engine? Where did you get your new engine?

congrats dude!!! :tup:

great to see you back on track!

Thanks for the support!

Engine was replaced with a factory new one and PPE LTHs, Z1 upper and lower intake plenums installed.

Honestly not sure what happened to the old engine at this point (I was not able to keep the old engine for diagnosis due to certain circumstances) but I am attempting to mitigate the possible causes that I have control over. Installed:

-Oil pan and pickup spacer (If/when I move to a race tire, I am considering an accusump)
-Bigger/brand new 34 row oil cooler (felt it too risky to try to clean out the old 25 anyway)
-Oil pressure gauge
-Using a thicker oil than the previous 5w30.
-Got a fairly conservative tune for better engine longevity hopefully.
-Planning on swapping in the Nissan Motorsports oil pump some time in the near future.

As a side note, aside from the obvious cage, seat/harness, also installed a differential cooler/pump, removed the AC and blower etc, Z1 clutch/flywheel (makes a huge difference on engine response). Car is 400-405HP (mid 340s whp) and 3185lbs with full tank of gas.

Phunks RRFP will be going in for next season and will cut a further 88.2LBS of moving/sloshing weight out of the car by running 14 gallons less fuel. Of course a pound or two will be added back by the pumping assembly.

A big thanks to Valkyrie Autosport for doing some fantastic work and getting me back on track!:tiphat:

Ooo. Brian builds nice things.

Well I'm locked and loaded now! :eekdance: Thanks haha

Also running redline 5w30 for the most additive micro lubricants I've seen plus best base stock made for oil so the hotter longer running intervals between changing won't shear and break down as fast, CJ oil pan coming soon, and just added a 48 row cooler along with removing the oem water/oil cooler and big purlator oil filter. My guess 9 quarts or more.

PS???????????? Why do they add the accumulator after the oil filter?? I just want to Tee it in coming back from the oil cooler. Is it because the accumulator will see unfiltered dirty oil or because the accumulator won't work as well pushing the oil back into the motor but having to go through the thick oil filter media slowing it down??

Good to hear. Yeah I am not against throwing in a quart of 0/40 in the summer time in the cali heat ;).
