Turbo back.

Cat back refers to the exhaust from the catalytic converter to the rear muffler (does not include the cat).

Turbo back refers to the exhaust from the turbo to the rear muffler. The whole thing basically.

So in essence,

Cat back = cat back

Turbo Back = dump pipe, front pipe, bigger cat, cat back

as your question asks whats better for my car... id say cat back because it helps keep your turbo running closer to factory conditions where as turbo back alows for more turbo rpm quicker spool up and better performance

correct me if im wrong please!

cheers and good luck

I don't get what you're saying Jenkies? Factory specs are quite restrictive and don't allow the turbo to perform as it's meant to. I dont see what's wrong witg quicker spool up and better performance?

If anything you DO want a turbo back, as it will be less restrictive, the turbo will spool up quicker and possilbe gain a psi or two due to the turbo being able to spin more freely.

Think like, the turbo can't get in more then it can put out, so if the exhaust is restrictive and the turbo can't spin those gases out, its only going to spin as fast as your exhaust will allow, so it won't be working as best it can.

      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.
