Is there any difference between a 993 C2 and a turbo rear cross member?

They have different part# but when I asked a quote for the turbo cross member, I was offered one with the C2 part#... what gives?
In photos they all look the same.

Also, Patrick Motorsport is selling one here, claiming it'll fit both: http://www.ebay.com/itm/PORSCHE-993-...-/170494174222
I'd think they would have a clue about 993 suspension...?

Different parts:

95 NA: 993 331 131 04
96+ NA: 993 331 131 06
Turbo: 993 331 131 05


duh, helps when i actually read.

i'm not sure what the differences are, but I doubt porsche is gonna carry different part numbers for the same part.

I know they have different part #'s but what is the difference? They look the same to me (and obviously some other people as well)

There are a bracket attachment points for the clutch assist on a turbo that are missing on the n/a arms, unless using the hydraulic clutch assist you don't need them.

ps some turbo guys bypass the clutch assist circuit anyway

not aware of anything for the clutch slave bolting to the crossmember

Bill Verburg

tt clutch has a separate power booster and associated, hardware, even the slave is different from a n/a car
here it is, clutch boost and slave, again not used on a n/a car

Thanks Bill!

I was searching for this info everywhere but just could not find the answer.
This means i do not need to order the turbo cross members for my EVO project as it will have an unassisted clutch slave.

but nothing bolts to the cross member the boost bottle bolts to the slave
i will take a look later to be sure
