I now find this mechanical speedo fiasco a blessing in disguise. While I wait for the new and correct Mechanical Speedo to arrive I have been going over the car thoroughly to double check everything is in working order. And good thing I did.
First: my dash lights were not working - blown 7.5A fuse.
Second: Tail lights were not turning on with switch, but brake lights worked. Again a fuse.
Third: Headlights were intermittently not automatically retracting when key is shut off. Had a connector that was slightly corroded. Sanded it down, resoldered. Good as new.
Then I rearranged the engine bay a little to allow for a little more air around the intercooler.
The AFM and air filter do fit in the stock MKII location if I move my fuse box a bit lower. Dont think it will be a problem having it there.
Then I hooked up the side engine fan from the MKII underneath the intercooler. I can turn it off or on from a switch in the cab. It may not do much, but I am sure it is better than nothing. If I close the lid I can feel a little air moving out - my theory is as long as it gets the air moving in the bay then thats good.
Sometime I will have to get a legit Spal fan and cut a hole in the engine lid as the MK1 lid is very restrictive
