1973 240Z refresh

[conedodger]

I’m opening this thread to document the process of refreshing my 1973 240Z. I have owned the car since 1980 and built 2 engines myself, in addition to running the original for quite a few years. This time, I decided to go with a Rebello stroker. Here is the car, and the motor that will find its home up front.

the engine is an N42 block, with an E31 head. The head saved me quite a bit of my Rebello budget as it was ported and polished by B.C. Gerolomy in the 1980’s. Dave just freshened it and put an appropriate cam grind in it for me.

One of my inspirations has been Duffy Mahoney’s build. We differ in that he used ITB’s and I will use a factory non-webbed, non-EGR intake with a larger throttle body. I have had bad luck tuning ITB’s. When about 8” of throttle body butterflys open, the vacuum goes flat. Duffy probably has more skill in that regard, but if I were you, I’d rather have me putting you to sleep for surgery. For tuning, I bow to him.

I painted the exterior in my garage a few years back, but the new engine begs a fresh coat of paint in the engine compartment. For that, I bought a new toy from Eastwood. 
Here, I found the only rust on the car. Owning it, since 1980 has allowed me to control many of the factors that cause the common rust spots. My battery tray support was surface rusted. The first pic is the before, the second after 5 minutes with the new SCT from Eastwood. There will be lots of hand sanding and Dremel work, but this thing is fast!

Like Duffy, I will be using Haltech EFI. Mine will be the Elite 2500 while I think, his is Elite 1500? Like Duffy, I’ll be using both cam and crank sensors so I can do both sequential injection and crank fire. I’m aware that there isn’t much to gain, but I’d bet it’s better for the environment, and us car guys need to start thinking about that too.
