Happy Fourth everyone.

A lot has been happening and it’s become apparent just how much I changed and how much has to be redone. Moving the turbo had all kinds of unintended (read: not thought through) consequences; every hose and tube connected to it changed. A fair amount of today was spent fabricating the seemingly simple intake elbow, but which had to be made just so in order to fit. Because I switched to a different type intake air temperature sensor, it needed a custom mount (thankfully I already measured its resistance curve). The new air sensor has a much faster response time, important in a boosted setup and is a Bosch 0 280 130 085 if you’re interested.

As you can see from the pictures the intake tract is very compact and the only real concern is how much the engine moves around due to torque. Don’t want engine movement to be able to pull a hose off, which means the fore and aft engine mounts need to be fairly stiff. I have a block of Delrin to fabricate a stiffer rear mount if necessary.

Moral of the story is that I need to quit fussing with the car and just drive it. Unfortunately there’s still the big project of fabricate the ductwork to get air to the intercooler. It’s either going to make the car even look more comical – or more bad-ass, not sure which.

While there’s still stuff to do before first start the list is getting shorter. There’s fabricating the wastegate tubing down to the exhaust, lengthening the wires for both the boost controller and the O2 sensor, finishing up the coolant bleed lines, and not much else, so it’s safe to say after checking everything for tightness, it should be running pretty soon.

Oh, almost forgot, that last picture of the wiring, notice how the green wire has backed out of the relay connector. I wonder how long it’s been that way. You find a lot of stuff isn’t as it should be when you take apart a car.
