Generally late model engines warm up a lot faster than older ones , my Evo 6 warms up really quickly and its an iron block alloy headed four banger .

Also remember the temperature most are seeing is the water temperature not the head block or piston temps .

My RB25 is a cold cow of a thing and takes longer to heat up than I reckon it should , the temp also falls quickly on long downhill runs on cold nights . New genuine thermostat going in very soon .

By the time you start the car and select a gear you have oil pressure (unless something is seriously wrong), just drive the f**k*ng thing. Aslong as you're not thrashing the crap out of it before the oil warms up it'll be fine.

As a few people have said, letting it sit and idle before driving does more harm than good.

^^^ rotaries always blow seals, nothing to do with warm up :whistling:

It's not about money why people do it. Idling at 2-3% load compared to driving it at 10% load can more than halve warm up period.

Even heavy truck engines alternate cylinders so only half are firing to load up and warm the engine faster

^^^ just pointing out how fragile rotaries are regardless of wether they are warmed up or not :rolleyes:

Not to mention fouling plugs if idling for too long (especially colder range ones)

I start and idle for about 30sec then drive normally off boost until oil temps move to 70degrees or higher...

Then I start the process of squeezing air down its throat :P

      This looks great! Awesome to have the 5 speed with an LSD in this. The Recaro's look like SR2's or SR3's. It's a shame they've been retrimmed as they would have looked sweet in their original colours. I think I'd want my agent to be a little more up front and informative too. I've never imported but I reckon it would make me a little nervous, so the more info the better.

      Thanks for doing that Duncan! Makes you a good person in my books. We don't get kangaroos or wombats here. But we have bats and it's similar. AFAIK it's often the mums with a baby attached that get hit because they drop lower when starting from a tree. If you hit an animal, check on it. https://www.ifaw.org/au/resources/wildlife-rescue-app An app to get the closest wildlife rescue contact.

      Jacks that fit under GTR lips that can reach the subframe?

      My dream is also to have a proper hoist, but I don't think it will ever happen. My quickjack is probably as close as I'll ever get, it really is very good though.

      Yeah we keep on in the dailies, it is pretty poor how many animals get hit and the driver leaves without checking....have saved a couple of little ones over the years. Bit of a gruesome job though, pouches generally need to be cut open because they are so tight and often the joey doesn't realise mum is gone so they are still locked onto the teat. I checked the modules in front of the DS wheel where an oil cooler should go.... There is the radar unit - that can go for race use) One of the 2 HX water pumps, the silver cylinder. That needs to be kept but might be able to be relocated But the bad news, the big computer mounted vertically in front of the wheel (blocking any potential air exit) is the electric steering computer. That is required until/unless i do a hydraulic steering conversion, and in CAD based modern car design it is not like I can just pop a big unit like that somewhere else (plus the loom would be too short anywhere else too). So, the passenger side is OK to clear out (just use a smaller washer reservoir, potentially elsewhere), but the DS no beuno

      Well, all the best with the new camry It was interesting to hear about the UK process, it is generally a lot more streamlined here with a shipping agent looking after all the import side (noting the exact final price can still be a surprise.....) and I've used a few different brokers on the japan (or US) side, and never had any trouble with any of them....luck of the draw I guess. You mentioned you didn't get the auction sheet (understandable since you bought it from a dealer, not auction), but I always try and get hold of that because they are pretty thorough. I've imported 2x R grade vehicles over the years and both were fine, repairs in Japan are pretty thorough compared to here in Oz.
