New 300Gt Owner, Few Questions

Hey,

So I just purchased a 300GT last week and was wondering if there are a few things I should know? E.g. regular cleaning

So from what I've read I should clean the throttle body every 10,000kms?

Also I realized on the fuel consumption screen that if my car is idle (waiting in traffic) the xx.x km/L drops rapidly (whole leaf turns grey), is this normal? The car has aftermarket 19" wheels if that changes anything.

I was reading the fuel consumption thread and people seem to be getting roughly 8.x or 9.x from city driving on their 350gt, I'm getting 7.5km/L from just regular driving around town which seems a lot worst than what everyone seems to be getting. I'm filling with BP Ultimate, been through 1 and a half tanks of fuel in a week..

Are there anything else I should know?

Thanks,

Richard

Why didn't you get a 350GT?!

I clean my car as much as i possibly car, basically because i like looking at a nice car showing all of it's glory. My 350GT doesn't have the T.V so no comment on that one.

Do you drive an auto or manual and does your car have CAI or an exhaust system?

^^ different states have different rules.. I believe the NSW rules specifically state 350Z and skyline 350GT as a prohibited vehicle, Vic may be the same??.. In Qld it seems to be 2 rules, and it depends who you talk to as to which one is applied.. as you say, the 350GT exceeds the kw/tonne limit.. but doesn't exceed the 210kw limit.. I am guessing that in theory... both should apply..

Before i bought the car i checked the KW restrictions and if the car was banned, and it's not. In NSW the 350GT is on the list of prohibited P plate vehicles. Unlucky!

I've never had any troubles with police whatsoever, even if these cars do turn illegal in QLD i will have an exemption because i purchased it before that came into play.

Yeah their illegal here according to the vicroads p-plate prohibited vehicles list.

Took a photo last night of the exhaust that came with the vehicle

Not too sure how many inches the straight pipe is

'test' pipes are usually a replacement for the cats. called 'test' pipes because they are illegal for road use.

In Richard's pic, it looks like they have just removed the rear muffler.. provided it isn't too loud, it won't be illegal.

Just had another look at the qld transport webpage.. it seems the general rule is less than 8 cyl, not turbocharged/supercharged (exc. diesels), less than 210kw, and no unapproved modifications.

However, if you are applying for an exemption to allow you to drive a high powered vehicle, then one of the conditions is it must be no more than 125kw/tonne.

Interesting the 350GT is not P-plate banned in Qld, but if it was, it wouldn't pass the requriements to apply for an exception... weird..

Not sure if you would get automatic excemption just because you bought the car before the rules changed either. Even for people that owned a car before 2007, need to prove there are no alternatives they can drive before they are granted an execption. and it would need to pass the 'less than 125kw/tonne' condition (which the 350GT doesn't)

Don't drive like a tool and you'll be fine :) I've had mine 6 months or so now and only been pulled over for rbt once. Fingers crossed for both of us haha!

Yeah I was thinking of going for a 350GT anyway but not really worth the insurance fuss imo, my leaf doesn't turn red, unless that's a 350gt thing?

Richard.

The leaf dropping to grey is normal is an economy thing to do with the computer so it goes like this: When your in stop/start traffic and sometimes around town the computer will sense that your engine is running but you are not moving much and that is not considered "economical" and will turn the leaf grey and give you that 7.5 reading.

When you are highway driving, again the computer will sense that you have your engine on, travelling at a constant speed and have travelled considerable distance which is "economical" and it will stay green and should raise is to 10 (im going off mine which is a 250GT as an example)

so when it has a green leaf, put your foot down and watch the leaf turn grey and you will understand what im on about.

i get 9/10km/L around town in a 250GT

i filled my tank (till no more would go in with BP 98RON, $136 later) and it lasted a week and a half.

also remember that you are in a 3lt V6 hauling over 1.5tonne around aswell and 1/3 of your power is lost on its way to the rear wheels.

hope it makes sense.

      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.

      By Duncan · Posted

      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.
