There's been lots of people talking about getting really bad fuel econemy me being one of them for me I knew it had to be my O2 sensor coz it was stuffed all the wires were melted. I'm not saying this is the same problem that everyone with bad fuel ecomemy has but i'll get to the point when i went to nissan they wanted $230 for an O2 sensor (RB20det) so I went looking and found this guy on ebay enginesensorsandsystems they were only $50 (universal) I was a bit worried about putting a universal one in my car but the price was right so i gave it a go, now the car runs perfect no ruff idle better fuel ecomony.

02 sensor wont affect idle. it is probably better to go for a genuine one vs a aftermarket no brander one as the voltage scale may be slightly out so it could affect say 5% fuel economy. a bog stock OEM one for the rb20 from repco should be no more than $90 for the correct one with the right plug.

R33 users can use the EL falcon one, althought there has been some specualation over it. I think the genuine one is only an extra $30 or so.

my idle is great, nice even rumble, like a even purrr @ .9k rpm, just get 200k's to a tank no matter what I do, whether i weld the throttle open or drive like miss daizy.

wiped the bottom section of the exhuast tip and see shiney chrome, drive it for about 20 mins, pop quater of a tank and she's black. visibly black smoke @ top end 6-7k rpms, but thought this normal considering its a nissan especially a line, getting rich up top always beter an leaning out anyway so when i bought it was fine, just hadnt noticed the monster thirst till i owned the damed thing....

have been wondering if its out of the norm but aparently the car is supposed to pull 400k's to a tank when flogging it. 97 S2 so hell dunno. on bp ultimate, first owner in aus, maybe its the ecu defualting to safe map? i've runn injector cleaner through it, gona reset the ecu in the hopes it will get better, just need to find a guy who can test it in my local area for a decent price.

I dont want cheap work but i cant afford big $$$ either at the mo

anyone around the ec area with a diagnostic machine that wont charge me a fortune to hook it up and give it a test?

    • Come to Eastwood, you'll get plenty of that 🤣
    • Oof, I will forevermore have those shredded gears in mind whenever someone talks about showing mechanical sympathy towards their car. Thanks for the photos, fascinating stuff!
    • Curious to see how the SpeedTek stuff holds up
    • The holdups last year were drivetrain related. I had the car out right after getting the bearing issue resolved. Third launch and the car didn't move after releasing the clutch. It had sheared all the engagement teeth off the 1st gear.    Thankfully no other damage was done. I set an aftermarket gear beside an OEM gear and found that the engagement teeth on the OEM gear were much larger and better supported. Looking through my bin of spare transmission gears I found that there are two types of tooth on the OEM first gears - the larger tooth and the smaller tooth. It looks like most aftermarket gearset manufacturers base their design on the smaller tooth. OEM large tooth left - Speedtek, OS Giken, etc or OEM small tooth right Decided to give that larger engagement tooth a try. Pressed the ring off an OEM gear and sent it to a transmission manufacturer here in the States. They did their "faceplating" operation with my synchro ring on the Speedtek gear.   I reassembled it, took it back to the track and promptly destroyed the gear itself.  I'll rebuild this and use it as a spare - thankfully just first gear and the countershaft are damaged beyond repair. Definitely disheartening but my welded on engagement tooth ring held up!  Moved to Speedtek's dog engagement design as the gears appear to be much stronger. So far they have taken much more abuse at the track. Also scored a Stillway lockout from the Netherands for super cheap. It's for some other RB transmission so it took a bit of fabrication to fit but honestly a very easy job. I also had to heavily modify the gates as they were very different.   Then for some reason at the last test and tune a silicon coupler below the throttle blew off and took out the radiator and fan. Thankfully it was in the burnout box and not down track. This car is really beating me up - I still haven't made a pass in it. Ran it through the gears many times on the street but it keeps biting me at the track.  Currently in the process of replacing the radiator and remaking the throttle pipe to remove the coupler and use a cast 90 and a vband. I WILL get this thing down the track...
    • Covers most of the above points really. There's a few exceptions but most just see driving as an irritating but necessary task they must complete if they want to get anywhere on time. Also see it as a good time to show their awesome multi-tasking abilities on their mobile and/or doing their makeup.
