just spewing coz its got absolutely NO midrange

the hks2530 is known for its midrange torque so there definately must be something causing your turbos not to start pulling and spinning the wheels as soon as you stab on the throttle.

sorry hud let me clarifiy you need to keep the restrictor as it reduces the size of the hole the air has to travel through which increase the pressure holding the wastegate(act) closed ( think about a garden hose when u put your thumb over the end) Ive read that by altering the size of the hole in the restrictor you can change how the turbo ramps up on boost ie make it spool slightly earlier or later( hpi mag did a build up on a jap spec s15 which they did this on) if your missing the restrictor entirely by using pretty blue hosing instead you may get the problem you have as there is not enough pressure holding the wastegate(act) closed

I remember reading in some post that the new 2530kai is rated higher than the old 2530 in terms of power...old 2530 was 320ps i think and the 2530kai is something like 350-360ps or something like that...try searching here...

      Duncan's V37.......race car?

      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.
