A year of slogging through this bearing issue and finally fixed. What a nightmare. The oil pressure increase did not fix the problem. If you would like to read all the details in case you ever run into a similar issue visit my thread on Yellow Bullet. https://www.yellowbullet.com/threads/continuous-rod-bearing-issues.2689569/?post_id=74193031&nested_view=1&sortby=oldest#post-74193031 In the end the rod bearings themselves were the issue. I had switched from ACL (first engine) to King because that was all we could get at the time and I thought nothing of it. Put the ACL's back in after a year of taking the pan off multiple times to change many things. Issue resolved. Can't believe it was just the bearings themselves all along. It has now been about two years since I drove the car on the street or had it at the track. At some point I had installed all solid and spherical bushings in the rear but had never aligned it since it just went on and off the dyno. Alignment was the first thing to do. (Old photo but same concept) Then I took the transmission out and went through it. This was my first gearset install and I've done about 15 since this one and learned a lot and wanted to apply some of these tweaks to mine. The aftermarket shift forks take very well to some modification and I wanted to make that change. Shifts are now super smooth and no having to find the gear. I also recut the 5th and reverse shift sleeves - always wanted to try this and see how well it works. It works very well! No grinds or having to do a second attempt going into reverse and 5th is perfect. Before During After Going back in In rummaging through my spare trans parts box I found the only parts I've ever broke on a stock trans; the 3-4 shift fork - twice! -
It also depends on gearbox ratio. Those drag cars running 7s passes aren't doing it on an overdrive gear ratio (probably). 1:1 is "fine", the critical RPM for a 50' single driveshaft in chromemoly is 6900rpm.... ....but when you shift into 5th and use 0:73 or 0:8 it all changes. Do you know their rear diff ratio? etc. That's the stuff that matters with regards to it. Whether it actually matters given your use application is also relevent. You may never get into those scenarios, like most ruined GTR's from Western Sydney don't :p -

but for how long? would it handle a few laps around SMSP in anger? -
And over it. Need to stop it coming through the floor. -
Is it running the standard ECU? some sort of data log might help understand where timing, AFRs etc are at. If it is standard ECU something like Nissan Datascan would help
