Whats the difference between these?

6776RE
6776RS
6776RSP
6776RH
6776RHB
6776RHPS
and finally the Boosted version available in mid 2007?
Whats boosted?

Here ya go.

6776RE = 67mm compressor wheel, P-trim turbine wheel, Dual ball bearing & TO4E cover, typically comes standard with a THB3-76 .63 A/R PTE 3-bolt turbine housing. (3" inlet, 2" discharge, .60 A/R on the cover)

6776RS = 67mm compressor wheel, P-trim turbine wheel, Dual ball bearing & TO4S cover, typically comes standard with a THB3-76 .63 A/R PTE 3-bolt turbine housing. (4" inlet, 2.5" discharge, .70 A/R on the cover)

6776RSP = 67mm compressor wheel, P-trim turbine wheel, Dual ball bearing & TO4S cover with Ported Shroud, typically comes standard with a THB3-76 .63 A/R PTE 3-bolt turbine housing. (4" ported shroud inlet, 2.5" discharge, .70 A/R on the cover)

6776RH = 67mm compressor wheel, P-trim turbine wheel, Dual ball bearing & PTE H series race cover, typically comes standard with a THB3-76 .63 A/R PTE 3-bolt turbine housing. (4" inlet, 3" discharge, .75 A/R on the cover)

6776RHB = 67mm compressor wheel, P-trim turbine wheel, Dual ball bearing & PTE H series race cover with 6" inlet bell (6" inlet bell, 3" discharge, .75 A/R on the cover) No provision for a hose to slip over the 6" inlet, will not work when mounting on a stock location/orientation 3-bolt Buick, the inlet bell will hit the intercooler pipe. In other words, this HB cover was not intended for use on a Buick application.

6776RHPS = 67mm compressor wheel, P-trim turbine wheel, Dual ball bearing & PTE H series race cover with ported shroud, typically comes standard with a THB3-76 .63 A/R PTE 3-bolt turbine housing. (4" ported shroud inlet, 3" discharge, .75 A/R on the cover)

All dual ball bearing cartridges are water cooled and will require water lines to be run to them. All of these turbos will require specific wastegate actuators with the correct brackets if you plan on using an internally wastegated downpipe setup. Standard or Heavy duty are available. They are all available with an optional THB5-76, .85 A/R PTE 3-bolt turbine housing.

And lastly.........

Boosted version available in mid 2007?
Whats boosted?

No idea, they are being very hush hush about this next generation of turbos.

Hope this helps.

Not true Just re-use your old Actuator and drill another hole in it just like they do. The actuator is NOT specific to the turbo. They use the same one and drill another hole in the bracket.

This is exactly how I recieved mine from Precision when I ordered their actuator for my new turbo

What I meant by that was, each one will require modification of a stock actuator to be able to bolt up. Whether they drill another hole and weld a backing plate bracket to it like yours and my TO4E cover equipped turbo, or as is the case with the TO4S cover, the actuator is modified and they provide a CNC cut aluminum bracket with special bolts to position the actuator correctly. Not arguing, just clarifying my statement.
You can not just bolt up a stock actuator to any of these without modification and spot welding a backing plate bracket to the actuator.
Most other vendors, aka T-netics suppliers do very similar modifications to the stock actuators to get them to bolt up correctly.
