I have for sale a good manual transmission from a 1993 na. As I'm sure you know, this will also work with twin turbo if you shim the starter. It has 115k miles, & works perfect. The only reason I'm selling it, is because I bought a complete JDM TT front clip that's going in my car, so this leaves me with an extra transmission. $325. I can usually ship manual transmissions via DHL ground for around $60-$80. If you want to check out my reputation before considering purchasing this from me, just go to ebay. My ebay user is "import-parts". I have 99.4% positive feedback rating, & over 800 positive feedbacks. I have 40+ other 300zx parts for sale there too if you are in need of other parts.
