a brand new crank from toyota costs around 1000gbp lol, so i dont think its an option buddy ... :haha:
as for him needing a billet/uprated crank is a bit to much... there are many many cars running double the power that he is on the stock crank without any problems.. i think he should take a good look inside his engine to see why the bearings failed... tbh id start with the oil pump, oil pressure relieve valve & then check the oil galleries & passageways for blockages.. just to make sure this doesnt happen again.
well the above is just my opinion of course

I think there is a slight misunderstanding here.
I wasnt implying he needs to buy a new crankshaft. I was stating that it could be an option but i too had also assumed it would not be worth buying one as they are bound to be mighty expensive.
Neither was i trying to say that he needs to get an aftermarket crank, i just stating that they are an option but also not very accessible due to cost and availability.
I too have seen and built engines making allot more power than his setup is pushing.
I agree with what you have said about finding out what the cause of failure was before putting it all back together again.
ts very unlikely to be old age, 100,000miles is nothing for a Japanese built engine especially a toyota. i have seen 4efte engines on over 240,000km pushing 250whp for years without problems.
Engines dont just spontaneously run the bottom end, there is always a cause weather it be mechanical failure or human caused.
a likely cause would be due to worn oil pump which is also directly related to poor servicing or maintenance.
silicon gasket material is capable of working its way passed oil filters and making its way through the oil pump and into oil gallery's then onto engine bearings, as is other such particulate when regular service intervals are not carried out.
the other main probability of cause is oil starvation, caused by surge whilst cornering at speed or lack of oil in the sump possibly under the same conditions of harsh cornering.
