Alright Guys,

I would really like to narrow this down for the benefit of all.

Are there ANY series 1 gtst owners out there getting over 400km per tank?

Lets do a quick survey:

- What petrol are you using;

- What mods (if any) and be specific (an exhaust mod can range from cat-back to muffler...);

- Have you reset your ecu since you got the car

- How many kms the car has done when you bought it (or now if ya cant remember)

- I think the boost guage is in a series 1 - what does it read when you hammer the car - 4-5500rpm

- Idle speed when cold, then when warm

That's all I can think of at the moment, when we have a few answers, I will draft up a table and whack it on my website so we can see in a table or something, some similarities.

Here are my answers:

1. BP Ultimate (am on 4th tank in a row now)

2. From what I can tell - only the exhaust system was changed to fit compliance. I did notice that my ecu does not have any LED system on it for Diag mode (?)

3. The second night I got it, disconnected the battery, pumped the brake 6 times

4. 85500 (close)

5. When 4000rpm+ it hits the first bar between 0 and +7. At 5500 and up it goes another quarter to be between the first bar and +7

6. When cold - 1100, warm - 850ish...

srb33 , get your car tuned if you have a pfc or a chip .

if you got a stock ecu not much you can do .

i have a s 1 r33 gtr with pfc and n1 turbos and i get up to 500 k driving around sydney , at least 450 k but i fill up when the red light comes on about 60 -62 lt .

the car runs 11.7 @120 mph and i dont drive like an old woman on a trip i get better .

when i bought the car with stock turbos and stock ecu ( turbo back exhaust ) best i could do was 350 -380k . a good tune not only gives you more power but better fuel economy as well .

i use shell optimax .

- Car - S1 GTS4 (NA)

- BP Ultimate

- Cat back exhaust + Pod Filter

- Yes - Have reset stock ecu

- 65000 KM when I got it, 80,000 KM now

- No boost guage!

- Cant remember idle speed exactly, but normal

- Currently getting about 20L/100KM :S.. Was going to replace O2 Sensor on weekend, but will do next weekend

Cheers :)

    • I'm looking for some real world experiences/feed back from anyone who has personally ran a EFR7670 with a 1.05 exhaust housing or a .83 I'm leaning towards the .83 because its a street car used mostly for spirited driving in the canyons roads. I"m not looking for big numbers on paper. I want a responsive powerband that will be very linear to 8000 rpm. I dont mind if power remains somewhat flat but dont want power to drop off on top. The turbo I've purchased is a 1.05, although the mounting flange T3 vs T4 and internal vs external waste gates are different on both housings, I not concern about swapping parts or making fabrication mods to get what I want. Based on some of the research I've done with chat gpt, the 1.05 housing seems to be the way to go with slightly more lag and future proofing for more mods but recommends .83 for best response/street car setup. AI doesn't have the same emotions as real people driving a GTR so I think you guys will be able to give me better feed back 😀   
    • Surely somebody has one in VIC. Have you asked at any shops?  Is this the yearly inspection or did you get a canary?
    • This is where I share pain with you, @Duncan. The move to change so many cooling system pieces to plastic is a killer! Plastic end tanks and a few plastic hose flanges on my car's fail after so little time.  Curious about the need for a bigger rad, is that just for long sessions in the summer or because the car generally needs more cooling?
    • So, that is it! It is a pretty expensive process with the ATF costing 50-100 per 5 litres, and a mechanic will probably charge plenty because they don't want to do it. Still, considering how dirty my fluid was at 120,000klm I think it would be worth doing more like every 80,000 to keep the trans happy, they are very expensive to replace. The job is not that hard if you have the specialist tools so you can save a bit of money and do it yourself!
    • OK, onto filling. So I don't really have any pics, but will describe the process as best I can. The USDM workshop manual also covers it from TM-285 onwards. First, make sure the drain plug (17mm) is snug. Not too tight yet because it is coming off again. Note it does have a copper washer that you could replace or anneal (heat up with a blow torch) to seal nicely. Remove the fill plug, which has an inhex (I think it was 6mm but didn't check). Then, screw in the fill fitting, making sure it has a suitable o-ring (mine came without but I think it is meant to be supplied). It is important that you only screw it in hand tight. I didn't get a good pic of it, but the fill plug leads to a tube about 70mm long inside the transmission. This sets the factory level for fluid in the trans (above the join line for the pan!) and will take about 3l to fill. You then need to connect your fluid pump to the fitting via a hose, and pump in whatever amount of fluid you removed (maybe 3 litres, in my case 7 litres). If you put in more than 3l, it will spill out when you remove the fitting, so do quickly and with a drain pan underneath. Once you have pumped in the required amount of clean ATF, you start the engine and run it for 3 minutes to let the fluid circulate. Don't run it longer and if possible check the fluid temp is under 40oC (Ecutek shows Auto Trans Fluid temp now, or you could use an infrared temp gun on the bottom of the pan). The manual stresses the bit about fluid temperature because it expands when hot an might result in an underfil. So from here, the factory manual says to do the "spill and fill" again, and I did. That is, put an oil pan under the drain plug and undo it with a 17mm spanner, then watch your expensive fluid fall back out again, you should get about 3 litres.  Then, put the drain plug back in, pump 3 litres back in through the fill plug with the fitting and pump, disconnect the fill fitting and replace the fill plug, start the car and run for another 3 minutes (making sure the temp is still under 40oC). The manual then asks for a 3rd "spill and fill" just like above. I also did that and so had put 13l in by now.  This time they want you to keep the engine running and run the transmission through R and D (I hope the wheels are still off the ground!) for a while, and allow the trans temp to get to 40oC, then engine off. Finally, back under the car and undo the fill plug to let the overfill drain out; it will stop running when fluid is at the top of the levelling tube. According to the factory, that is job done! Post that, I reconnected the fill fitting and pumped in an extra 0.5l. AMS says 1.5l overfill is safe, but I started with less to see how it goes, I will add another 1.0 litres later if I'm still not happy with the hot shifts.
