I've done a lot of searching to find the manufacturers of modified oil sumps for the RB26

so far I've found the Tomei baffle insert and oversized oil pan

http://www.tomei-p.co.jp/_2003web-catalogu...RB_oillube.html

also the Performance Metalcraft sump

the High Energy one (waiting confirm on RB26 pans, although their website does state they do RBxx)

http://highenergy.com.au/index.php?module=...me&content=home

then there is accusump

http://www.accusump.com/acc_products/acc_units.html

there is also the Greddy/Trust oil pan upgrade kit which is also an insert into the normal pan

are there any other companies in Aus that make custom sumps ?

Do many people use the sump baffles? Is this enough with the oil gallery restirictor, oil cooler, baffles and N1 oil pump to prevent oil starvation in most track/drag/street applications ?

Or should you spend the extra money and get an oversized sump and either N1 pump or Tomei or Trust oversized pump

regards

Jason

Hi Jason

It really comes down to what you plan to use the car for.

Personally I think track work is the hardest on the lubrication system as lateral forces are more likely to result in oil starvation than straight line acceleration (the pics on the Tomei website explain this well).

I went for the Performance Metalcraft option as it provided both additional capacity and baffling without hanging too low (I don't like how low the Trust sump extensions hang). Not a cheap option 'tho!

With regards to oil pumps - there is plenty of posts on the subject about what you need. I picked up a Trust pump at a good price, so that's what I use. I also use a restrictor in the block oil feed gallery.

An oil cooler is a good idea also if you do track work.

I'm sure there are plenty of other ideas and options, but this is the way I've gone.

Cheers

Gav

      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.
