Do you actually need a cannon? i'm not that well educated on the subject, but i thought cannons were for turbo cars, NA versions needed something more substantial to create sufficient backpressure to run well (or something like that). Anyone feel free to tell me otherwise, i'm in the market for a new exhaust system and don't want a loud, droning note.

if your exhaust is 2.5" factory its probly crush bent.

somthing that could make your guys lifes easyer with r33s you could buy the turbo guys factory exhuast as they are 2.5" mandrel bent from the factory. i have one on my car even tho its rb20e.. but that will be gone for a rb30de soon. lol.

yeah N/As need some back pressure as it helps the scavanging effect. a muffler like a flowmaster one would probly sound good. i will replace my stock rear muffler when i get the new motor put in as this one is a little rattly and doesn't make much sound. plus i don't get the typical skyline backfire :huh:

correct - stock exhaust was/is crush bent. will be interested to hear about your experience building the RB30DE

well so far i have most of everything that i will need to get it up and running. you can see the difference in rod lengths of rb30 and rb25. i just need to get the bottom end rebuilt and the head put on then i can finish the rest. it has a braded hose running from the head to just next to the oil filter. i will post some pics up when i have the basic block assembled.

i am only missing 3 major components, gearbox, clutch and computer plus ill need custom extractors.

it should be good when its all up and running. ill use a plug in GTS link once it is run in. hopfully completed and in car by end of january to mid febuary :D

Are you sure stock piping is 2.25"? I measured mine this morning for the new muffler and it came out to be a fraction less than 2" - the guy who imported it told me it was "dead stock". Why would anyone put on an exhaust which was smaller than stock (and mild steel to boot)?

      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.
