Help me with some questions about a r34 swap. Rb20 or 25?

[GAMBLE]

I have a rb20 now in it so I don't know if the 25 would be more work? I have a rb20de and want to go turbo 5spd. Mines auto blahhh so what's the best choice? Which route is the best? And easiest? Jdmsource has both motors rb20det and 25det. A couple hundred bucks apart. I had to sell my phone to buy this car now I'm back to a iPhone 4 the screen is sooo tiny!! Omg sacrifices!! Anyways thanks for the help.

Neat. Lol I've learned something. Far as I know you can swap it to 25 with very little trouble. Wiring Loom will need to be modded a bit I bet.
