So I got lucky. on this second day (my fourth ever on the air strip/track), I was seeing little improvements in my times. I was letting it fly. I had realized how to read/memorize the course map and develop a plan. After the official autocross was done for the day we had 3 runs each as a fun run. I was getting personal best times yet & felt like I was really pushing it.
But on the last run I pushed it too hard for my skill level & for my crappy tires. I came in too hot to the slalom on a tricky angle & when my wheel was crossed up I nailed the brakes, then the "the most spectacular spin out of the day".
So I slid into the grass & sail this run way light (they are know for destroying hard parts like wheels, oil pans, suspension). And sure enough I hit it with Wilson's nose.
Thankfully I don't have a lowered car & thankfully I DIDN'T HIT anything other than the front valence. It broke off & I had to fork out $100.
These short clips show most of the course. In the pic much of the driving looks straight but it's actually slalom. And there are figure eights on both ends of the tarmac.
assuming its an NA, youll need the whole shebang off the 87...struts, mounts, spindles, hubs, rotors, control arms, castor blocks/bushings...i think your springs and brake calipers will swap over.
Anyone recognize the cam shaft that my finger is NOT pointing to?
The finger is pointing to a 944/2 (1988 8 v 2.5) cam.
The other one is supposed to be a "warmed up" cam, but I'm calling b.s. Hopefully I'm wrong.
Also BOTH have a "P" (porsche) and a "S" (sachs?) in the casting, but the new "hot" cam has these casting numbers:
The profile of the duration looks to be similar to the late cam. My finger is pointing towards the budge in the casting of the known 1988 stock cam, where as the other doesn't have it.
the non-pointing-at cam (bottom of first pic) is a 85.5-88 camshaft as well. the part number -9R gives it away.
whether it has been warmed over or not will require measurement of course.
Yup. V2. I don't think it's been warmed up... Just another bs story from one porsche dude to the next I suppose. Thank you for confirming the initial model of cam. I am merely inventorying what's what at this point. It was kind of fun way to start the day.

Grab a vernier caliper and measure the cam lift on the unknown cam. Subtract the base diameter from the lobe height on both cams and you've got lift numbers you can compare. If it's a reground cam it'll have a smaller base circle. The appearance of the ramp profile isn't everything.
