Now I do have a few pictures for you.
The next post in this series is about the rusty floors.

I took the XJ out for a 45 minute drive this evening and it's definitely running better than it was when I got it. I certainly can't trust the brakes yet, but they are better. The ignition system seems to be working nicely now as well. It's been a bit hard to start a few times, especially after sitting for a while, so I'm suspecting it may have some leaky injectors. The truck drives just fine. It just needs a whole new suspension. On smooth pavement it's fine, but on bumps or broken pavement it just comes completely unglued. I figure the shocks are long gone. I'll be installing a mild lift kit with new shocks before too long anyway, so it's not a problem.

Driving impression: so far so good. There's a little more intake noise and my highly calibrated butt can detect a little more responsive throttle. Nothing dramatic, obviously. It's a tube.

In this photo you can see the fuel pressure regulator. When installing the '99 Miata head on the '94 block, it's necessary to use the '99 fuel rail with the '94 fuel pressure regulator (FPR) because the '99 is a returnless system, while the '94 uses a return to the fuel tank from the FPR. The '94 FPR can only be oriented one way, due to a vacuum port that has to face out. That's no problem, but it dictates the routing of the fuel hoses. You can see this one sticking straight up, and the other one sticks straight down. The '94 fuel rail has an input that has a flared end on it so the fuel hose with a clamp on it will be nice and tight. The '99 uses the newer style fittings that click into place and require a special tool to remove, so the input to the rail has NO FLARE. The '94 FPR has an output on it that is flared, and so must be a clamped connection. Being ignorant when I embarked on this project, I blithely bought the first spool of high pressure fuel hose I found online and simply clamped the hoses to the fuel rail connections and on the other end to the fuel hardlines from the tank. It worked for 2000 miles.SAE 30R9 fuel hose (Gates P/N 27085), so the clamped connections will work. For the '99 fuel rail input, the 30R9 hose is fine, but you need to make the connection with one of these. It's DORMAN part number 800-081.5. It's a nylon 5/16 inch 90 degree barbed fitting. It needs to be 90 degrees because the space under the fuel rail is very tight and a straight fitting doesn't fit. I got 5 of them from Autozone online for about $12. It was a special order item so I'm not sure if you'll find them at your local store.
