someone tell me why?

i drive an ek1 right now and i want more powerrr and a bit more luxury features..

i could do a b18c swap onto my ek1, but for the same amount of money i could sell my ek1, save up a bit more to buy like an ep3 or dc5, which already has the power, and some luxury features from factory.

i was thinking some turbo cars like rex and evo, but i wont be off my ps for the next 2.5 years.

so, can someone tell me why its better for me to do an engine swap onto my ek1??
