need a hint on how to convert a 4 bolt 240sx to a 5 bolt

hi guys. i asked this earlier aswell but didnt get any reply.
i still hope to get some hints here.
i have a 240sx with jaquemond wide body kit.probably one of only two in toronto or even in GTA.
i want to change the bolt pattern from 4x114 to any 5 bolt so i can have wider rims to line up with the wide finders.

i have 245 wide rims but still i use two spacers and i dont think its safe.
if i change the bolt pattern somehow, i know a place that has alot of 5 bolt wide rims from japan.( wider than 305)

please guys…i need help and if you give me some hints, i will be more than happy.
thank you guys.

i will see you guys this summer in TNC meets.

alz.
