Theres actually a vf52 for sale.
Get a tmic/ grimmspeed ebcs/ dw65c fuel pump/ oil supply line with oil filter from infamous and you can make some serious power.
Regarding the turbo oulet, they rip easily so if you dont rip it when installing the new one then dont worry about getting one, but be prepared.
Heres my mod list with the vf52
