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

'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?

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.

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

      Even more fun, leave all the ADAS stuff plugged in, but in different locations, hopefully avoid any codes!   And honestly, all these new cars with their weird electronics. Pull all the electronics out Duncan, and just shove an aftermarket ECU and if needed a trans controller in, along with a PDM. Make it run basic but race car styled!

      To follow up a question from earlier too since I had the front bar off again (fking!) This is what is between the bumper and the drivers side wheel And this is the navigator side, only one thing but its a biggy! So basically....no putting coolers in the wheel arches without a lot of moving other stuff. Assuming I move to properly race prepping this car I'll take that job on and see how the computers respond to removing a whole bunch of ADAS modules

      So I prepped the car for another track day on Wednesday (will be interesting to see coolant temps post flushing out and the larger reservoir, with a forecast of 3-14 being 20o cooler than last time I took it out). Couple of things to mention; since I am just driving the car and not taking a support vehicle, I took the rear seats out and just loaded the back up Team Trackday style. Look at all that space! To cover off removing the rear seat....it is weird (note the hybrid is probably different because it wouldn't have folding rear seats) Basically, you remove the lower seat base, very similar to a r series but it is a clip that pulls forward to release the base rather than it being bolted down. Easy Then, you need to remove the side section of the rear seat on each side. There is a 14mm head nut at the bottom of the side piece, the it slides upwards off a hook at the top to release; you also need to unhook the seatbelt from the loop at the top. Then the centre piece is weird. You need to release/fold the seats forward with the tab in the boot on each side From there, there are 2,x12mm headed bolts holding the rear of each seat to the folding bracket, under the trim between the rear seat and the boot (4x christmas tree clips there, they suck). The seat is out but you can see where the bolts attach to the bracket

      As discussed in the previous post, the bushes in the 110 needed replacing. I took this opportunity to replace the castor bushes, the front lower control arm, lower the car and get the alignment dialled in with new tyres. I took it down to Alignment Motorsports on the GC to get this work done and also get more out of the Shockworks as I felt like I wasn't getting the full use out of them.  To cut a very long story short, it ended up being the case the passenger side castor arm wouldn't accept the brand new bush as the sleeve had worn badly enough to the point you could push the new bush in by hand and completely through. Trying a pair of TRD bushes didn't fix the issue either (I had originally gone with Hardrace bushes). We needed to urgently source another castor arm, and thankfully this was sourced and the guys at the shop worked on my car until 7pm on a Saturday to get everything done. The car rides a lot nicer now with the suspension dialled in properly. Lowered the car a little as well to suit the lower profile front tyres, and just bring the car down generally. Eternally thankful for the guys down at the shop to get the car sorted, we both pulled big favours from our contacts to get it done on the Saturday.  Also plugged in the new Stedi foglights into the S15, and even from a quick test in the garage I'm keen to see how they look out on the road. I had some concerns about the length of the LED body and whether it'd fit in the foglight housing but it's fine.  I've got a small window coming up next month where I'll likely get a little paint work done on the 110 to remove the rear wing, add a boot wing and roof wing, get the side skirt fixed up and colour match the little panel on the tail lights so that I can install some badges that I've kept in storage. I'm also tempted to put in a new pair of headlights on the 110.  Until then, here's some more pictures from Easter this year.

      I would put a fuel pressure gauge between the filter and the fuel rail, see if it's maintaining good fuel pressure at idle going up to the point when it stalls. Do you see any strange behavior in commanded fuel leading up to the point when it stalls? You might have to start going through the service manual and doing a long list of sensor tests if it's not the fuel system for whatever reason.
