Use an adapter .. if your dead set on a 4 bolt set ... its super easy to modify a 3 bolt design into a 4 bolt... just a flange change
 
I did buy a adapter and wasn't to thrilled with it, since Im stepping up to a bigger turbo I thought the adapter could cause a little lag
 
instead of the 3 bolt to 4 bolt adapter maybe just get an actual flange these companies use cut yours off and weld on the 4 bolt

I think theres more to it than r&r the flanges, the area right below has to be enlarged for the 4 bolt flange
