if i were u i would go a s chassis with a regoed rb25det in it or buy a 32 with a 25det in it.
33s are way to boaty on the rd even if you do sus mods.
32s are the best to drive and 34 for looks and power.
my old 32 4dr rb25det man is up for sale in sa but he wants to much now he put up the price.
if not keep it in the bank and give it 6mths and 34s will come down again.
many r32 with 25s for around 10k tho or even less. keep looking and dont buy the first one u see.
but that is my 2c
