Someone else in this thread asked where to get the adapter, Screamin4banger had already posted where to get it.G-Pop shop has 4-pc carbon seal kits for about $100. Give them a call & they'll tell you what you need. I think a rebalance is only $45. If nothing's touched, it won't need that, though. To use the TI Garrett on an 88+ TI car, you'd need the TII style compressor housing without the 90° outlet. TU sells them.
