ive sourced a RB30 bottom end of a mate, and has got me thinking,

Im also trying to source a RB25det NEO AWD for my GTS4 33,

Now, i havent been able to find much on this, let alone a NEO

i want to put the NEO 25 head on the Rb30 bottomend.

What will need to be done RE AWD, modified sump?

also any problems with the NEO 25 on the 30 bottom? woul dit be that much diffrent from a no neo 25head going on.

cheers for the extra reading material,

Ive got Unigroup Engeneering build this for me feb/march next year. They have done this before, Just not in a GTS4, though they would set this up as they would GTR.

Around 6k labour.

If this dosnet work out, The 25det NEO will be going in, And the 30 a little down the track, Just seems better to do it all in one go.

Any other major parts i should supply them apart fromt the 25det neo, and the 30 bottom end?

organising a Front facing plenum, Due the the extra height of the Rb30.

still sorting out the rest of the list

You or they will have to get the sump adapter plate. Depending on use think about a sump extension and dependant on oil pump and use have a read of the oil control thread. Definitely enlarge and relieve the oil drains and fit restrictors to the feeds. Make provision for a sump breather near the dipstick ...running to a catch can I believe is fine or to the back of the head if you think it works as a drain as well.

Otherwise as per pdf

But - choose pistons carefully for RB30 -neo head combination.

No one mentioned the fact that u have to cut and shut the belhousing to bolt up to the bottom of the block.

And whats the issue with this? The conversion has been done maney time before. Any particular reason you bring this up?

      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.

      BTW I measured the jack I have, it is 70mm at the saddle but you only have about 700 until it returns to 150mm high at the cylinder so it is good but no magic bullet.
