your crank has been damaged and is too far gone to be reliable. For your walletts sake spend the money and get a new collar fitted.

Couldnt you have used the PM feature of the forums???

I know your well in tune with how it works :P

I thought id use the thread to tell him also inform others who's crank looks like this.

Is that ok ?

thanks mate!

Will spend a lil more for reliability.

How do i fit the collar in?

I read somewhere it needs to be welded on?

Crank needs machining to an interference fit for the ID of the collar then its grub screwed (supplied) to secure.

Chilton Engineering up here in Brisbane do a good job on the collars they supply me. Billet machined to a tighter fit. They don't have the stupid grub screws that the JUN collars have.

Machine crank down to a 3thou interference fit and shrink it on. Get your local engineer to do it.

Also....not exactly sure but I think Marty White makes them for him. You'd have to ask David Chilton though.

JUN collar is a waste of time. David sells them to me for around $100 then fits them for a further $80

    • Why are you so adamant on going M12? Why not follow Brad (GTSBoy) suggestion. You're talking moving from a 1/8" size, to a 1/2" effectively. 4 times bigger. Why skip the commonly available sizes in between? The bigger you go, the more likely you are to strip the threads out at a later date, as guaranteed, someone will put a huge spanner on the M12 and really tighten it up, and you're only in thin wall, so not a lot of threads to engage!
    • Hi. Yeah thanks. Car is already at tuners and it staying there to resolve "many" issues they do not like. So it is in a good hands. Getting a good tune on that Nistune ECU too so the car would be good. Just needs a little tune up and love.
    • Probably gonna remove manifold and turbo. I’m not sure if I can get M12 x 1.5 air tight. Could use high temp Loctite 246 or something similar, but I don’t know. Maybe it’s just best to remove everything again and weld an 1/8NPT on there instead.
    • Yeah, saw the ratios, not impressed. Would like the punch I have in the first gears now. With those ratios it won't be the same.  Also want the h pattern gearing, or at least a quiet gear set that don't need to come apart for service each year. Looks like the only "reasonable" way Is a 8hp70 transmission, but where is the fun in that🤷‍♂️
