Hey guys.... I just purchased a used TE61 from a friend that was upgrading this turbo on his car. It was on his car when he bought it. Supposedly it has the .63 Precision exhaust housing and has a small amount of shaft play.... but was still on his running car until he pulled it to sell it to me. If I elect to try and rebuild this turbo myself... if I can find a kit...... what potential newer wheels can be installed to upgrade the older TE61....?? I was thinking I might try to upgrade to the newer 6152E. Is this possible.... and will I see a difference... on a mostly stock motor.....? What would be a better option to upgrade to? ..... or just leave it alone...?
