I have for sale three JDM Insider DVDs as well as a JDM Option for sale
$40 for all four
And I have three technical instructional dvds that I got ages ago. The quality is great and the guy takes you through every step and really helps explain everything. I found them very useful when I owned my 240sx.
The dvds are:
S13 KA24DE Removal DVD
S13-s14 KA Intake manifolds in-depth and emissions removal DVD
