If you knew the material and dimensions I bet you could get a new one laser cut for a lot less than $300. It's just a flat plate with a little hole in the middle!

I don't know about Turbos, but my N/A has the 82C thermostat and like your turbo it sits between the white zone and the first tick. The fan switch I'm not sure what it is, but it usually comes on just ...

All the numbers on those graphs have to be doubled as they're in camshaft degrees for some reason but we normally talk about ignition timing in crankshaft degrees, which rotates twice as fast.

I received MOT advisories for both of the items in the title, for both sides of the car.

Now, we know the MOT testers can be a bit stupid about the 924 sometimes such as the front wheel bearings, w ...

You'll have to spin that pretty fast if the name implies only 400cc per revolution!

Also I don't think you can have the throttle after that SC anyway, it makes internal compression so if it's not s ...

I never understood how Porsche expected the guide pins to remain lubricated or even NOT corrode with them being completely exposed.

Modern cars I've worked on have seals to keep the grease in and t ...
