G'day everyone!

I have a technical question that i cant find any info on - on here, so thought i should ask.

Purchased 2x new Garrett 707160-5 / GT2860R turbo's for the 32 GTR.

Tag on them Labelled from Garrett - 707160-5 / GT2560R

I went about changing the pieces over and came to the oil drain pipes, they dont fit !?

The original Drain pipe bolt holes are spaced much further apart compared to the new turbo's mounting position.

Has anyone had this issue with their swap of turbo's or are the new ones labelled wrong and henced supplied wrong?

Does anyone knnow what the deal is with them labelled 2560 not 2860 also?

Please help.

Many Thanks

Harry

Yeah Garrett in their infinite wisdom decided to change the oil drain side to T28. As stated above you'll need to file them out to match the other holes. You may also note that one of the comp cover bolts will foul on the oil drain. IF you don't grind an angle on the head of the bolt it will stop the oil drain from sealing properly so make sure you do that as well

Those turbos are 2860s. The 707160 number shows that, they just must have put the wrong tag on them.

Also make sure the oil drains seal real good, use a new gasket and tighten the f**k outta those bolts. They are the biggest pain in the arse, imagine replacing the turbos and everything only to find that the oil drains leak. Then you have to rip them off all again to seal them up again. That's been the story if my life for the last 2 days :)

Thanks for the help guys.

GCG called me back today, these turbo's are designated under GT2560R now. (707160-5, 707160-9, 707160-10)

You can buy a kit from them now for the drain pipes with this new size - XTR420043.

You can find it here:

I have one coming, i'll let you all know if it sorts the issue with having to file the compressor housing bolt for clearance also.

Still, this doesnt help if your like me and have the Nismo oil catch can. The Nismo fitting needs to be modified to this new flange size to bolt up.

I might see if they can make an option part for that also.

Cheers.

      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.
