I 2nd SC300 although honestly budget will be probably be blown because of the small stuff, but that seems to be the case always 
I went with the 1jz VVT-i swap, full torque at 2400 rpm, so on the street it's great. It comes with the remote R154.
Notables- Wiring sucked but was straightforward. I built the intercooler and exhaust piping. Custom driveshaft. To get full integration with the cluster, a few fixes needed. Unlike some of the others mentioned, in general you can make all the power you want to in the future, and not worry about the drivetrain.
