Nice Cup engine!
Do you also have the aluminium intake?

I also have a Cup engine (1995) in my 993 and it love the power and raw race sound it makes.

 

thanks P ... no ali intake - isn't that RSR?

 

​​​​​​I mean the intake you see in Bill's post #5. You see it well in picture nr2.

 

Cup used a plastic '95 type manifold w/o maf, the fuel mixture was set vis w/ tps and map using a modified 55pin Motronic brain


aha I see - sorry yes the ali intake mount for the air filter .. very nice (lighter )

 

Light and very sexy
I have removed mine and use a 993 MAF as the Cup engine runs best over 4000 rpm. I use my 993 in the road also .....

 

Does yours also have a double crank pulley? Sure no aircon on a cup?

 

Did buy a RS aircon twin pulley and still have the aircon. I am faster aroud the track hot summer days with the aircon ON

 

ok so a couple more questions ....

is this the right part for a cup engine?

 

Yes, but it needs a special plate and hose that connects to vent the distributor

 

thanks Bill .. I made one in CF for the 964 3.8 I did .. is that one plastic or ali? Pipe to dizzie as usual.

What's the best option for air intake filter in your view? 50/50 track/road car.

 

also intrigued by the size and design of the camshaft end cover / plate 993.105.117.2R ..(assuming it's also cup correct) .. it seems so big and larger/deeper than necessary.




I previously had one of these made for the 964 when I removed the power steering and just blanked it off much like this one ....it's seems simpler .. not as effective somehow?

 

The cover for the dist feed is 964.106.409.80 and is made of plastic, easy enough to duplicate

The p/s cover is available from multiple places, Patrick, Rothsport etc

 

thanks Bill, will do the same re the shroud plate as I did for 964 - is the 993.105.117.2R end cover pictured above correct for the cup?

 

Yes, the 993.105.117.2R is what I have on my 95 Cup engine.
