Hey, does anyone know whether a Supercharger or a Turbo Charger is available for the 94 LS400's?

There are superchargers available for the 4.0L in Austrailia. Unfortunately, they won't work in our 4.0L because or ECU problems. The only way to go would be a custom setup.

Yah, I got that message too. I believe there is a Japanese Turbo available for the LS. I saw this picture of a LS400 with a Apexi Intercooler, which is what makes me suspect there is a Japanese Turbo kit somewhere.
