The B18b is just begging for a turbo.. I definately am a fan of turbocharging the LS but youll want to look into doing some other things at the same time. Such as plugs and wires, and maybe a mild head job. But you can turbo it as it sits and run like 5-7 psi all day for a good while. I turbo'd a LS/VTEC and it ran for 2 years b4 I took it apart to go all motor. Its pretty much up to you.
