while your doing that might as well slap a turbo on it :)

You'll need to remove the head if thats the case. Might as well throw a gasket kit at it while you're there, just to be sure. Drop the sump and replace the con bearings while you're there ... hell, re-ring it too. Check for abnormal wear and tear.

Best to spend an extra day and $300 freshening up the motor, just to be sure.

I did it will all my engines I picked up for cheap. :D

edit: oh, while the head is off, remove the valves and clean them up too.

your curve Joel from like 95 is like hold on and enjoy the ride :D

For Rad33 with his new rb25det on the way.. Get an rb30 under it. :P

RB25det vct head FTW for bottom end. :D

AL's motor is running the same GT3076 .82 on an rb30det but with a nice exhaust and inlet manifold with slightly smaller cams. The VCT has picked up some nice low end power peak power appears to be made around 7000rpm.

Now for mine.. :P 15.5psi that can be seen and the last tune at 19.5psi through the mid that tails off to 17psi causing top end to flatten out. The 2" fmic piping is causing issues up top as well as the wastegate flap being blown open.

Mine makes its peak around 6000rpm. Will play with the adj. cam gears to shift that to approx 6500rpm. :D

lol we could of told you that cars never miss behave once you get them to the mechanics - PM send about AFM's

So when the mechanics drive my car it doesnt shit itself?????????? FFS!

so where does that leave me? high and dry.

the only thing i can do is.... what for it to happen again and make sure it happens at the mechanics?

ill have to try and clean out the AFMs and check for damage.

Damo :D

    • Hi all,   I have bought a JDM R35 at auction in Japan.  This is my second JDM GTR after owning one back in 2009.  I have made a couple of videos that may interest some forum members.  One is collecting the GTR from the compliance shop (and seeing it for the first time) and another on the process of buying and importing a car from Japan.  I'm new to this and would appreciate your thoughts, as well as a subscribe!    
    • Sorry, AFM.    Will edit original post
    • Oh, yeah, no arguing that the duty cycle is different. And a circuit car will go to those speeds for more distance and longer times. But, I suspect that if a tailshaft has a harmonic problem, that it would cause damage and shit itself maybe even on the first pass. A second or two of running at the resonant/harmonic problem speed is already a couple hundred revolutions.
    • Shaft speed would be the same, however it's how long they hold it there for and repeated conditions. FWIW half way down the main straight at SMSP I'm bouncing off 4th with a 8600RPM limiter. That shaft would be spinning at 8600RPM for a few seconds before I need to smash the brakes, by T2 it's getting close to that speed again. Now a drag car/roll race car would see that shaft speed for a 1 to 2 secs then they would coast, hit the brakes and that's it.
    • With same diff ratio, tyre diameter and road speed, the tailshaft rpm is the same regardless of the gearbag's ratio. Given that very quick drag cars are probably doing similar road speeds to the fastest circuit cars (circa 300 km/h), and there will be many of either category that can't go that fast and so you'd have inummerable matchups between drag and circuit car speeds at smaller numbers, and given that they are probably using rather similar tyre diameters and probably using similar diff ratios, and...where any of those numbers were different they could quite easily be in opposite directions thus cancelling out.... I think you'd find that there'd be more similarity than difference in tailshaft speed between these two use cases, no?
