1982-83 Silvia ZSE-X and Gazelle

The Z18 hasn't been made for nearly 20 years. They would easily fit in a 1200, except that their 8 spark plugs make them a pain in the ass. You'd definitely have to rebuild the engine once you'd found one in reasonable condition. I've heard of people modifying them back to 4 spark plugs.

I've also heard that gaskets and spare parts for them are excrutiatingly hard to find. This is why people put CA's and SR's in the cars. It's a longer term solution.

I've seen some FWD QR-20's etc floating about. I wish someone would start looking at them. Even the QR20-DET out of the Japanese Terrano would be INTERESTING.
Although no car in AUS uses this engine yet, so it would be better to wait for the QR.
