I ran both both types of forced induction on a 1994 22RE 4x4 5 Speed.
The Camden supercharger that LCE uses in their kit is very old technology, with no bypass valve, like the Eaton/Magnacharger (TRD) does in Tacomas. This lack of bypass valve and the straight cut of the lobes gives it terrible gas mileage. I saw easily as low as 12mpg with the supercharger. A bit of an easier install, though, than the turbo, and great low-end torque.
The turbo, with the intercooler, actually improved my combined city/highway gas mileage by about 2 mpg so I was getting about 23-25 mpg. It also pulled way harder at any comparative boost level to the supercharger, probably due to the lack of intake air temps. Install necessitated a local welder to attach the downpipe and wastegate pipe to the exhaust. A much more involved install with much better results. I would recommend getting the CNC'd manifold LCE kit over their tubular-style one.
For either, you will have to provide more fuel and be able to retard the timing at anything over about 3-4 psi, at least that's how it was for my truck. It's a lot of money to spend for only 3-4 psi run off of the factory computer.
I would suggest LCE's MAF conversion from the later Tacoma 4 cylinders in conjunction with URD's "5th Injector" kit. This will allow you to control fuel and timing. You will need a hi-flow fuel pump as well as a way to monitor the Air/Fuel Ratio.
You could also go the stand-alone engine management route, but that requires tuning at a pretty complex level.
It's definitely worth it. Boost puts a smile on my face every time.
