What seat do you have in your 944? I'm 6'3" with a long torso and am looking at new seats for track days, wanted to see if people had any strong recommendations.

The coolant pipe doesnt need to be changed to get rid of the expansion tank. you can remove it with all the original coolant lines. I just liked the way the hard line from the 951 is smaller and closer tot he engine than the larger n/a tube. There are 2 ports on the radiator that the expansion tank connects to. you just need to disconnect those 2 lines from the radiator then put some plugs over them. The tricky part is to then get an inline filler cap. You can place the filler anywhere you want but it MUST be the highest point in the system. I welded mine right on to the water neck on the top of the head where the bleeder screw is because that is the highest point.
