actually here in NZ its the other way round,evo owners are upgrading to vr4 ratios to help with drag racing-namely avoiding having to change into 5th if their car is fast enough
i had a disscussion a few years back with a ralliartNZ workshop and alot of their evo race cars were being rebuilt with vr4 gears as they were apparantly stronger/heavier than evo's im yet to be convinced of that but id have an evo gearbox with ratios changed to the 3.545's
