Anyone heard of these mods?
 

Some of the things the shop wants to do when I get my new engine in along with the supporting mods that are listed in my other forum about pump gas.
Has anyone ever heard of this part?
TR-3650 Bolt on Hydraulic Out Bearing Assembly w/Fitting

Or doing this?
Set Up Custom Adjustable Throw Out Bearing

I'm pretty sure that the second thing is the labor for the part, but what is the advantage of a Hydraulic Out Bearing?

I found what the part is and what it does, but I can't find how much it should cost for the entire assembly w/fitting. Anyone know how much it should cost for the S197?

They are talking about the hydraulic slave for the clutch. Your car came with one stock, it includes the throw out bearing. A stock unit can be had for less than $100. There are only two companies that make an aftermarket one, RAM and Mcleod. The RAM unit cost about $350 and the Mcleod unit cost about $500.
