I am wanting to slightly boost my R32 GTR to about 12psi with a bleed valve. What is the correct way to do this. I know that you can remove the restrictor in the boost solenoid line to get something like 1bar but I don't want to go quite that high(close to ceramic turbo limit). Can I put a bleed valve in the same line as the restrictor to get my approx 12psi and is this the correct way to do it?

I have done a search but found nothing on this issue other than to remove the restrictor totally. I want to get adjustment in between having the resitrictor and having no restrictor.

when you say "and bleed a little" in what line is your bleed valve located. Do you mean a T peice in the line that normally has the restrictor in it with a bleed valve going to the atmosphere???

Removing the boost restrictor generally gives between 12-14psi.... i'm currently running 1bar (boost restrictor removed and bleed a little) on my stock R33 GTR turbos and have been for over 20,000kms

Ok, so this tells me how to get boost level ABOVE that with the restrictor removed. Thanks for that but it hasn't answered my initial question. So referring to my original question, How do I get boost between that with the restrictor in and that with the restrictor out. I want it t be ADJUSTABLE(bleed valve) between standard boost and boost with no restrictor. There must be 1000 people who have done this, anybody???

Or tiny holes drilled in the vacum line :D

fit your bleed valve to the hose that usually has the restrictor in it.

      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.
