Oh crap!  I can ask in NZ if you want, there are usually a bunch sitting about.

Could put 5s one in but would have a bit more stroke

Yeah, I suppose it cant hurt.  In the mean time, I will continue to see what comes available locally.

After getting another replacement crank, purchased as a '3sge' crankshaft, I found out it was different.... not a 3sge or 3sgte crank.
 
Now, once again, I'm on the hunt for a replacement crank shaft.  I picked up another one & fitted into the engine, only to realise that is was from a 3sfe (slightly smaller diameter where the flywheel bolts on).  
 
If anyone knows of a 3sge or gte crank shaft, please let me know.  (need one in standard size) as I have already purchased all the standard size bearing etc to suit.

be aware, toytoa graded their cranks and are sized for Toyota graded bearings only. its easy to end up with far too much oil clearance if you use off-the-shelf standard bearings (ACL, Clevite, King etc) and you crank is on the low limit (very common) or has has more than about 0.0005" wear (quite common)
 
we always grind road car engine cranks to the 'high limit" to keep clearances to a minimum . for race engines, the bearings are fitted to the rods and block, measured, and cranks ground to suit
 
if you have no luck finding one locally to you, call or email me
 
 

***PURCHASED*** crank.
