OK, here's a question for the GU 6.5 owners' out there.
What is the clearance from the oil cap at the front of the engine to the inner hood?
And if you are running the A/C on the passenger side, the clearance from the compressor to the inner hood.
I'm trying to determine if I need a "non stock hood" with the P400.
Sorry Ralph, can’t help with either measurement mate. I’ve already installed the new hood and my NA has the A/C compressor down below on the passenger side.

I thought the accepted P400 mod for the Patrol was change the sump so everything else stays the same.
FWIW mine has the ZD30 bonnet (A/C on upper pax side) and oil filler, A/C and I/C all fit tickety boo.
If you raise the entire engine to suit the factory sump then you will run into issues other than just the bonnet clearance I would imagine
Thanks Mr Twin (or can I call you Evil)
Good point that you make regarding the oilpan.
From my research, there tends to be minimal clearance at max travel, between the oilpan and the diff, so I was looking at possible options there.
I too Ralph was under the impression that the sumps on the mighty P400’s would need customisation to fit in our GU Trols. Something to consider doing this fit might also be oil volume in the end. My NA stock sump holds a measly 8.6L and are currently increasing total volume to over 10L at least needed IMHO by way of PeeBee’s fin twin cooler and long lines.
Do you know mate what the P400’s stock oil volume currently is as I’m thinking that maybe the P400 girdle not only strengthens the bottom end but could expand oil volume needed beyond the sumps max limits possibly?

OK good point MB, what would be the ideal oilpan capacity be then?
Cheers Ralph mate!
10L+ I believe for my old grunt NA slug hillside twactor. If you’re looking to SC the beast you’re building I’d uneducatedly say shiploads.
I am honestly/truly needing to learn what a GM fixed weapon P400’s oil capacity is so I can please try to mimic! Thanks mate!!

the service manual says 7.6 liters (8 qts)
Update on oil cooler added recently. Was using it in mid 30's over the last 4 days and oil temps were between 25 - 40 deg less on the discharge side compared to input side in low range 4wd, say 5klm/hr average and mid 30's air temp. If the vehicle was stationary, as was the case with the winching activity which took maybe 30mins i guess, the temp difference was perhaps 15 degC, as there was no forced airflow over the fins - very impressive to say the least. Driving home on the freeway, the difference was 45 -48 degC at 100klm/hr, 2000rpm, EGT 300DegC, air temp circa 30 Deg C
What are you guys doing for lift pump and filtration?
