300zx n/a injector help

[brettgilroy05]

Okay guy's I've got a few questions about 300zx n/a injectors. A few days ago I went to the dealer and found out i have 4 leaking injectors and the need to be replaced asap as this is my daily driver. first off, does anyone know the size of the OEM injectors? also, is it true that if you get bigger injectors you have to get your fuel system re-mapped? because i found some venom 550cc injectors on ebay for $395 for all 6. My car is bone stock except for C/A intake, If i was to purchase these injectors would i have to make any other modifications, or would they fit right in. And my final question, if I have the dealer do the maintence for me, what other parts will i need to purchase for the job? ex: seals, o-rings, gaskets? any help is greatly appreciated.

I replaced mine best deal i found was rebuilt injectors from Z1motorsports. $40 a piece plus $40 core charge. they come with upper and lower o-rings. If your going to pull the plenum off by a upper intake plenum/manifold gasket $14.99 from nissan as well as two plenum egr gaskets. Stock n/a injectors are only 270cc, stock tt are 370cc. You cant use bigger injectors with your stock ecu. 90-92 n/a injectors are the same and i believe that 93-96 have a different style fuel rail. You can actually find that info on the z1 site. good luck hope this helps. http://Z1motorsports.com

Stay away from Vennom unless you like snake bites. I hear they have too many problems.
