Outer Limits 4x4 Board

Had a minor mishap with the engine so just completed new pistons and a few other bits n pieces.

With a little tuning aspiration in mind what would be a good replacement turbo for the ct12b? Preferably ball bearing garret or along those lines.

Im not sure what you'd fit, but i have noticed that the boost drops off quite considerably after 3000rpm on the 12b- drops from 13psi to 10psi on mine, then down to about 9psi at 4000rpm!

Then again, my jap spec 1KZ seems to tuned differently to aussie specs- aussie 1KZ's max out at 9psi!
