My build is near complete and the car will be going to the tuner in a couple of days. Info on the power fc running the alsd is difficult to obtain. Have any of the more experienced users had any dealings in this area and, If so, what is required to marry the 2 together?

"Vehicles such as the Nissan Skyline R33 GTST that feature the Active-LSD or A-LSD and SLIP function (lights on the dash and vspec diff) will suffer A-LSD compatibility problems. The car will operate correctly and the diff should as well however you will experience "A-LSD" error/failure intermittently. To date there is no known solution for this problem. It appears to be only present on the R33 RB25DET. There was a limited run of R33 known as the GTS25TML spec which is the M Spec with Active LSD. The diff is a skyline GTR vspec diff, electronically controlled LSD instead of a normal R33 diff. It features the same finned cover and A-LSD function as the Skyline GTR. The A-LSD and SLIP functions in the Skyline GTR with the Skyline BNR33 PowerFC work fine, only the ECR33 with ECR33 PowerFC is affected."

I seem to remember a discussion on here from a few years ago about this, and from what I remember the problem had something to do with the throttle switch signal not being passed from the power fc to the lsd controller. Could be wrong as it was a while ago. Try a search for alsd.

      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.
