can someone tell me what these are all about ??? will they work on a stock engine ??? i seen these on ebay thinking about buying them but im sure i see these on this forum last year and a little bird told me that basically they were f$$$ked and the bloke couldnt get them to work properly does anyone know if these are the same ones ????

only if it's the full kit for the 300ZX. and the price is reasonable..otherwise it's far too much work to make these fit and there are much better (ballbearing) turbos around nowadays

 

they work on a stock engine, but all depends on how much power you want to make.

you'll need at least larger injectors, intercoolers and preferably an engine "fresh-up" (new or aftermarket pistons + bearings) for added safety.
