I've been waiting ages for someone to have a real go through that post and sort it out. Seeing as I know absolutely nothing about enguine building, I was blindly relying on what was written. Toymods is a fantastic resource but the search function can be a complete pain in the ass (especially searching for 2T). Having much discussed information like this condensed cuts out the 'noise' that the forum conversations tend to generate.
From my perspective I would love to see information like this condensed on the A series as well as the JZ series motors. Perhaps if I'm bored at work again one day then I'll start the mega-search to find all the 4A stuff. I'm imagining it will take decades to wade through the crap though.
