+1 to KAT-PWR.
I was KA-T but now I'm in the process of 1JZ VVTI swap.
More potential
Greater support
New experience (never swapped before)
Sounds better
Fun torque curve (VVTI!)
Cool factor
KA-T did me well but I had a budget setup I didn't want to build up. I chose 1JZ over RB because of the crank collar issue and to be different from a good friend of mine who's RB25. I chose 1JZ over 2JZ/RB26 because I'm not looking for big power, just near OEM power levels (BPU as the Toyota guys call it). And I like turbo power too much for LS. Turbo V8 would be cool but I'm not looking to spend that much just yet..
