For sale I have:
One L20B factory turbo. These were a trial thing in emerging markets back in 79' this one was shipped to me from taiwan. Its a bolt on turbo for an L20B.. Comes with everything to install, efi, turbo exhaust manifold, turbo, and all the piping, only good for 7pounds of boost I beleive. these were designed by nismo. Maybe someone can chime in if these work on l16 or l18. anyways located in moses lake wa and $700 or trade for nice 4x114 rims.
One L20B factory 6 speed transmission, these are very rare, these came stock in some rally variant 510's in finland. These are acctually long tale so they fit 280zx and 620. this boosts an l20b's top speed up to 190mph! I had this paired with the turbo in my 620 for a while and it shifts real smooth. Located in washington, $600 obo
lastly, I have factory lsd for a 620, bolt in, came out of a jdm 620SS the super rare supersport edition. had installed for a while works good. $400
If your interested I can post pics....
