Hi im after 2 injectors standard and can not find one can anyone help or put me in the right direction im a newby to the 300zxs  

Welcome to the Club! What year is your car and is it a Twin Turbo or NA Z32?

Hi sorry for late reply its a 1993 twin turbo Brown colour injector

Those will be the early style pintle 370cc injectors (for 1990-1994 TT fuel rails). Part# 166000-40P07.

New, the seller here is well known and trusted on Twinturbo.net

I would also post a wanted on here as a number of members have swapped out 370cc injectors for larger ones and may have s/h working

ones available.

 

Hi thank you i just dont know how to work this site as im rubbish on forums lol also i was told the r33 injectors will fit but theyre 555cc do you know what if be looking at roughly for a tune and who could do it many thanks for your help appreciate it 

370cc injectors will run to 1 bar (14.5psi) safely. But that would be the limit. If you want to go with larger injectors

then you will need to change the stock ECU's EPROM which holds the mapping data (including injector specs).

I would suggest you speak to Jim at PowerZed to discuss your tuning requirements and budget.

There are a few types, early and late style side feed injectors made by JECs for nisssan. Early Z32s used a square plug type, later an square oval shape, the date this changed is different between TT and NA. 
 

Most Z32s will be early type. 

Early NAs have red square topped 270cc injectors. 

Early TTs have purple square topped 370cc injectors, this go a chocolate brown with heat and age. 

Later spec are the same colour and sizing. They are not however a drop in fit and require an adapter kit. The R33 as some models came with the late style 370s, same as a later model Z32s. GTR models and R34 cars had top feed 440cc injectors, these require too much effort to fit. There are Square oval side feeds in 440cc and 550cc in some factory cars such as Subaru’s. Be aware any change to the injector size will require a new EPROM to run the correct fuelling. 
 

Remapping is possible either by a chipped and socketed ECU and fitting an off the shelf EPROM or preferably a custom map. There aren’t too many people who will touch the Z32 ecu as a stock unit and switching out for a Nistune board will make finding a tuner easier. 

Thank you for your help i think i’ll just stick to the 370cc injectors if you hear of any please let me know else it’ll be ebay thank you
