Before this gets deleted: i HAVE searched

My question is:

If i get 2.5" catback (is there a cheap version of this thats just as good as the fujitsubo one?) and coby extractors, sure there will be performance gains (particularly in the low-mid range)... but my concern is, what is it going to do to my FUEL INTAKE :D !! please tell me it won't be affected so I can go ahead with it.

Also, what's a good and trustworthy shop to get mufflers made/fitted in SYDNEY, preferably Westside.

Thanks all

P.S. if you want to see my car its in my profile's gallery

ive got a 3" Trust full stainless steel catback on my GT and i got a 16.9 kW increase, ive also got custom made extractors on but not sure whether there has been a power gain or not (have not been able to get her back on the same dyno). what you must realise is that getting extractors put on dosent mean you will get extra power, however you will (or should!) notice the car being alot more responsive..i noticed it straight away from picking her up after the getting the extractors put on.

fuel wise i havent noticed a change at all, put extractors should help wit the fuel economy a bit.

hope this helps

any increase in performance/power is going to use up more energy = fuel

so your FUEL INTAKE CONSUMPTION is obviously going to increase, as to by how much - who knows, it's dependent on your tune, style of driving and associated components.

if you are unhappy with the current rate of fuel consumption, then obviously don't mod the car.

how many liters per 100km is calculated as follows:

  1. fill up your fuel tank to full
  2. reset your trip meter
  3. consistently drive in your regular style until it's time to fill up
  4. check your trip meter (~400-500km??)
  5. check how much fuel you put in at the second fill up
  6. the amount of fuel you put in (liters) divided by the number of kilometers travelled (in km) multiplied by 100
  7. voila you have the amount of liters used to travel 100km

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

      By soviet_merlin · Posted

      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.
