Bonnet risers make a good difference. You'll see the heat demisting your windscreeen in winter. Dont know much on this particular chassis setup but If you're using the oem thermostat(opens 82°), swap it out for a Billion thermostat (opens 65°) or golebys stocks the Mishimoto (opens 68°) dont try no thermostat like you would SR, JZ hate it. If you can run a rad beneath your support or modify to v mount instead do it (may eliminate ac) but ac condenser also restricts flow significantly and heat soaks motor pretty bad. Vents may help a little but wont solve it. Ducting rad with foam or shroud to force maximum efficiency helps. Ive had nothing but trouble with mishimotos, cfm is horrible and motors randomly dying or running slower/unevenly etc. 1JZ need minimum 3200cfm, get yourself a pair of Derale/with shroud, twin 12" 260watt, 24.8 draw each, 1800cfm low/2400high so total 4000-4800cfm make a huge difference. Whatever rad youre using go minimum 2 core 35mm diametre, triple core 50mm will be too hard to work with. Find a dual pass rad also, (not just 2 core.) Get yourself a water spray kit of the rad so if summer/drifting does get too hot you can quickly cool and minimise damaging anything faster. Also been hearing about and seeing many in Japan lately are blocking off the waterneck joiner, adding swirl pot eliminates possible airlocks in back of head and bypassing where turbo and head meet waterpump so turbo water isnt heatsoaking head. (Currently researching more into this mod) Lastly if youre running 98, last choice (sucks) but may have to consider flex fuel and using e85 for the lower running temps too. On my 180sx using dual core, AU thermos(3200cfm) shroud ducting, billion thermostat etc, running temps were often as low as 68°, summer average 72-82, drifting 80-90, certain driving repetitively under elevation/load 85-110° on 98. Hottest ive gotten was matsuri 40° summer drifting got 118°. Can improve on the 180 however by doing dual pass, better cfm, and e85 options in future. Your bay design, fmic and front bar will be the biggest restriction/cause. If you can, look into alternate front bars and relo or swap ic to allow more freeflow into rad. ( side note: Dont bother trying push fans wont help) I battled cooling a decade ago too, tried absolutely everything to stay on 98. Hit up Brendan Ryan on FB. Drifts a 1jz IS200 like a boss, he may be able to help with more info pr solutions with your particular chassis. 🤙 Good luck! Hmu if needed :)

So much good info thanks heaps! I‘ll dig into these and see what I can do 😁
Well hooded
Good to hear you are whole and well Jack 😂😂
Works every time 👍🏼
60% of the time works every time 😎
Ayye got the feature 🤙 more 180 in the future? Big plans, no funds
Big spend then big send. If it’s not wrapped around a tree on the channel I’ll be disappointed 😂
5:58 Wtf you snitch Nathan
We saw it
I thought Jzs dont make much heat??
Correct this is all clickbait
