A well built 2.6 will give more power then needed on the street, JEs and Carillos are more then upto the power you want as are all the others mentioned so whatever you feel comfortable forking out for will work just fine
but if the crank has to be replaced anyway then for the extra cost a stroker is the way to go for the extra capacity, I am nearly finished with a rb2630 build, capacity is king but how much, I think its size v cost v hassle, if I did it again the BC 2.9 would be the way I went
I have brought from those ebay guys before with no hassles
