Im in the restoration biz and honestly we are guess speakers at conventions and club events on this very subject..... Just on Italian cars not Japanese. Anyway, the wow factor was nothing short of stunning. I get it that lots of these great little cars have fallen in to the hands of ........ well lets just say the "unskilled youth". And some have been saved by young guys and gals that did incredible things to complete their vision. I met a young lady that did all the work herself and absolutely rocked that 510! I offered her a job she did so well with her car. Anyway, I found a killer 510 local. Worked a deal, and will be picking it up soon. My engine builder has socked away a N.O.S. SSS motor he has been sitting on for 25 years. And we will be using that! The car car is a 71 two door and a lot of really good work was already done to the car. Meaning all rubber was changed, complete suspension refresh too.
What is the ideal diff for a 510 with a 1.8 SSS motor and a 5 speed trans?
Does a 510 respond well with camber on the rear or is it a bit twitchy?
Who makes the best "drop in" no mod needed header?
Awesome news!
I'll address the 3 questions, since I'm a Datsun collector / restorer...
In my 510, I run a 3.90 R-160 LSD. Not cheap, but they're out there. Same diff as Subaru (Nissan and Subie use the Fuji Heavy Industries diffs). Look for a close-ratio 5-speed for more enjoyment.
There's an ideal range of camber - always a happy medium. Depends on other factors, such as drop, tire / wheel setup, and type of suspension (coilovers or shocks/springs).
There's not really a GOOD "drop-in" header... Headers for Datsuns (and most cars, in fact) are usually more hassle than they're worth. Cracks, leaks, and bad design conspire to make it NOT worth the hassle. The SSS exhaust manifold is pretty well-designed, and it won't crack or leak. The minute HP gains you might get from a header aren't worth the PITA of pulling the motor to deal with repairs / leaks. Have the stock manifold runners cleaned up, have it Jet-Hot coated, and enjoy trouble-free (and quieter) motoring.
Probably not what you wanted to hear,but lots of experience (and lots of mistakes) over the years. Get her put together, and you can address those issues as the project progresses.
