im replaceing the 550cc injector for stock 370s the two intake pipes i have are giving me the shits cant wait to get her going good
i need to make them stock cause im running stock turbo's adn these ones my ecu does not calculate fuel pressure reading for 555cc but i will be selling the injector's once i have got them out but at this stage i am amazed at how un service freindly the zx really is i have to take the whole plenum section just to replace the injector also i dont know where alot of the air and water pipes go
Fuel pressure is not calculated by the ECU. I'm assuming from your post that larger injectors have been fitted without the ECU being reprogrammed. You can remove the injectors without removing the plenum ... just google 300ZX dremel method.
seriously take out your ECU send it to PZP ask him to socket and change the k value on the rom it currently has. Why would you want to revert from newish 555's back to 20 year old stock 370. Depending on your over all engine condition, with a good after market fuel reg, bigger intercoolers and boost controller you can crank up the turbos and go where the 370 cc injectors couldnt take you.
370cc im going to put the 370ccs in because it will save me fuel when i put my foot down if that makes any sense lol im going tio buy another zed later on in the year and im gonna spen around 10 grand on doing that one up zedz RULE
Confused.... why would you buy more then one zed? Just spend the money on that one and do it properly. You can only drive one car at a time
I think you need to do some reading about how injectors work and fuel delivery. Start in the tech section. Read as much as you can because a good knowledge of these cars is worth a lot of wasted time and money especially if you plan on owning another one.
