Ford 8.8 Super Duty Rear Differential Conversion Kit for my 71' Datsun 240Z There are several different companies that have Ford 8.8 Differential conversion kits for S30 and later model 260 to 280z. However, most of them utilize the earlier model of Ford 8.8 Independent Rear Suspension from mostly 2005 Ford Explorers,Mercury Mountaineers and other SUV models. These differentials can handle 400HP and some even have Limited Slip in them. So they have been utilized in Drift Cars,Ford Trucks, JDM Cars and even BMW Racers. But, finding one is difficult because high demand and limited supply. Fortunately,a New and Stronger Version of the 8.8 came about-the# Super Duty 550 Differential with started to appear in 2015 Mustangs with Coyote Motors. This model can handle from 600 to 1000HP ( with beefed up). It weighs over 100 lbs and comes a Torsion Limited Slip. I ordered my Super Duty 8.8 from Summitt Racing for $1300with 3.55 Gears. + shipping. At the same time, I ordered the Sonan 8.8 Drive Shaft Adaptor from Summitt Racing for $179. They manufacture Two Versions of this Adaptor. One for Manual Trans and One for Automatic Trans. The difference is the number of splines on the Pinion Shaft. My 3.55 pinion takes the Automatic Trans Adaptor. It is constructed of Billet Aluminum and handle alot of horse power. This adaptor costs about $179.

Things got super busy again but this evening I went ahead and hardlined the oil cooler. I'm a bit out of practice on stainless so I accidentally put a couple of tooling marks in the tubes. The line sections are short so I'll work them out with a hardened rod when I wash everything out and rebrush the finish for final assembly. It's one of those things where I need to remind myself to slow down and think things through otherwise I end up making more work for myself or waste material. I also hit the AC Hardlines with some steel wool and wd40 to get a uniform finish but it's is a bit bright for me. I may go back and redo those in brushed as well. I realize I keep getting busy so this weekend I'm going to try and dedicate a solid half day to wrapping up the turbo cooler packaging updates.

My workspace is a mess so this evening I started cleaning up before proceeding so I threw the intercooler back on to check clearances for the AC and oil cooler sections. I think everything looks good to continue fabrication. My welding station is currently set up for AL which it never is so I've been contemplating also hard piping the intercooler with aerospace wiggins clamps. Not sure if it's worth it for this ebay special as the clamps and separate weld ferrules are eye bleeding expensive but I'll simmer on it over weekend projects.
