hi am after help with installing my 26/30 setup.

when i bought the engine it only had the plenum fitted, so since getting it i've been piecing all the little bits together, i'm slightly unsure on a couple of pieces as most people that have done the conversion already had an rb26 and dont need to gather up the parts, as so they are not mentioned in their builds.

do i have to use the steel water/vacuum tube that runs alongside the block to connect heater hoses and to the plenum etc, just wondering how other people have done it as their are not many pictures or info on this when using single turbo, without this there are a few hoses that have no where to go and i would like to keep the heater for road use.

if i dont need it which hoses can i block off and which hoses can i connect to each other to not interrupt flow?

i am also curious on the aac to booster pipes, do i need to use these or can i connect the brake booster to somewhere else on the plenum and block off the back of the aac?

any information would be much appreciated as i'm almost finished and so badly want to drive the car again

any help appreciated, thanks luke

Not sure on the Options of the brake boost but mine is connected as factory. Regards the metal pipe you mentioned. On my build I cut al the vac lines of and kept the main water one IIRC. I might have a picture somewhere. I will look tonight. I think there is a spout you can block and also on the RB30 block there is a little spout on the rear water pipe into the block that can be blocked. I will try and find pictures to confirm for you.

Not sure if this is correct but it worked well for me.

Left side of vacuum sensor (under injector manifold) to vacuum side of throttle bodies (one of the pipes coming down). Other side of vacuum sensor to plenum.

Other pipe coming down to brake booster. Block off the rest of plenum nipples and use top small nipples on manifold for boost sensors.

I made up my own heater pipes, one from front of block at thermo housing to heater then heater to the last nipple of block (left in picture behind small lines). I had an external oil cooler setup not like your stock water one but you could have the return heater line going to your oil filter/cooler then from it to block.

Not sure if the small lines are for turbo but if they dont plum into the blocks oil or water then get rid of them and use bigger lines from other side of block (may need to be drilled and tapped but worth it).

My idea is to keep it flowing and simple. Block diagrams can help you see how water and oil moves through the RB30. I remember that it looks like pluming for the turbo water in from one spot and out at another wouldnt flow but it does due to the suction of water passing by the connection point.

      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.
