This is a 100% stock replacement for an 86-87 turbo Regal or 89 TTA, but with a few upgrades.
It has improved oil control and reduced drag with a dynamic oil seal on the compressor side. With an improved thrust capacity with a 360* thrust bearing.
A new billet seal plate is used and greatly improves appearance. Stainless bolts and clamps are used on the exhaust side for a long lasting appearance.
Works well with all the Standard typical upgrades for your Turbo Buick
