Hi guys,

Was just wondering if anyone new the length of the std conrod , as i'm looking at the GT Nismo crank and rods (the crank looks to be around 78.5mm stoke and the conrod length 121.5mm)i know the std stoke is 73.7mm but i dont know the conrod length? Has anyone used this items in a build up?

Are you still looking at an N1 block as well Pete?

no but i am interested in the gt crank, but i already got Pauter rods which i would most likely have to sell if i when down this road and buy the gt rods or something similar.

std rod length is 121.5mm

cheers

Pete...that is std Rod length. You need to use special pistons which run a smaller (by 2mm) piston pin height

OK THANK YOU GUYS

so i can keep the Pauter rods and use a GT crank but have to run special pistons to allow for extra stoke?

I'm thinking some of the after market kit might have gone down the same road with pin to deck height reduction (hks 2.8 etc) will have to see what i can find out and prices of the nissan verses after market gear.

You could always get custom pistons (2mm smaller pin height) and use the GT crank with your Pauter rods. The GT pistons are not forged.

Incidently, the crank that tomei supply with their RB28kit looks alot like the NISMO GT (Z tune) crank (I reckon it is the same one).

The Tomei crank uses shorter rods, 119.5mm and standard pin height on the pistons. But the Tomei rods look much nicer(and lighter) than the NISMO ones.

The longer rods would be better for RPM, but apparently the Tomei kit is still good for 9000RPM +.

i thought the gt pistons were forged as in the Z tune specs they talk about forged light weight pistons (z tune uses all the gt gear)

trying to confirm this at the moment and see if i can actually buy the gt pistons

the standard lenght is 121.5mm

the get around it by using a heigher pin height on the pistons. :P

besides the gt crank isnt a full counter one!!!!

acording to the pics on the nismo site.

    • Update: I got the magnet out. I bought 3 different flexible magnetic reach tools, but none of them worked. The magnet on the tip was all less than 2lbs of force, so i had to buy a special cylindrical magnet that had a pull force of 9lbs.  The magnet finally came in the mail yesterday, so i got under the car to get to work. The super strong magnet isn't that long, so i only have about 1 finger pinch lengths to hold it. I was so scared when i was going in the hole, that the 9lb magnet would just fly away inside the oil pan never to be seen again, but i had my butt cheeks clenched and finger gripped on that thing so tight, i managed to get it to suck the other magnet out.  It was a victory for me last night.         
    • Yep, pretty much what you said is a good summary. The aftermarket thing just attached to the rim, then has two lines out to valve stems, one to inner wheel, one to outer wheel. Some of the systems even start to air up as you head towards highway speed. IE, you're in the logging tracks, then as speeds increase it knows you're on tarmac and airs up so the driver doesn't even have to remember. I bet the ones that need driver intervention to air up end up seeing a lot more tyre wear from "forest pressures" in use on the highway!
    • Yes, but you need to do these type certifications for tuning parts. That is the absurd part here. Meaning tuning parts are very costly (generally speaking) as well as the technical test documentation for say a turbo swap with more power. It just makes modifying everything crazy expensive and complicated. That bracket has been lost in translation many years ago I assume, it was not there.
    • Hahaha, yeah.... not what you'd call a tamper-proof design.... but yes, with the truck setup, the lines are always connected, but typically they sit just inside the plane of the rear metal mudguards, so if you clear the guards you clear the lines as well. Not rogue 4WD tracks with tree branches and bushes everywhere, ready to hook-up an air hose. You can do it externally like a mod, but dedicated setups air-pressurize the undriven hubs, and on driven axles you can do the same thing, or pressurize the axles (lots of designs out there for this idea)... https://www.trtaustralia.com.au/traction-air-cti-system/  for example.... ..the trouble I've got here... wrt the bimmer ad... is the last bit...they don't want to show it spinning, do they.... give all the illusion that things are moving...but no...and what the hell tyre profile is that?...25??? ...far kernel, rims would be dead inside 10klms on most roads around here.... 😃
    • You're just describing how type certification works. Personally I would be shocked to discover that catalytic converter is not in the stock mounting position. Is there a bracket on the transfer case holding the catalytic converter and front pipe together? If so, it should be in stock position.
