I am planning to turbo my car...
since my injectors are leakin and not holdin pressure after dealer ran tests on them.
I am planning to get 300zx turbo 370cc injectors.
As far as i know it should fit in 4th gen maxima.
Is this going to be a good with stock FPR and stock ecu with upgraded fuel pump?? and am i goin to run rich??
and if someone can tell me the part # for the injetor would be great
thanks

 

anyone???
i really need to get this done asap...coz i know mingo is almost done with the piping.

 

You need an afpr to lower your base fuel pressure down or you'll be idling really rich (if you manage to idle at all).

larger injectors = more fuel volume per pulse
upgraded fuel pump such as a high pressure walbro 255 = increase idle fp from 34psi to ~42psi.

 

oh okay...is the N/A 300z injector 370cc also?? or its like our stock injectors?
thanks ewuzh

 

NA 3z injectors flows like our stocks. only turbo 3z flows 370cc

 

what a great reason to go boost ! way to go

 

370CC and a Z32 MAF. That is all you will need. Dont need to even mess with your FP!

 

sounds good...i'll do the MAF and injectors and hope everythin goes well
thanks Jay25

 

I suppose the z32 maf compensates the duty cycle automatically?

 

Someone is using that setup right now NA. He was boosted just had not had a chance to pull off the injectors. Z32 bigger MAF will compensate. Its a larger MAF. I used the setup too. Going right to it.

 

say you are N/A and you add a 300ZX MAF what will that do for you and is it a direct bolt on?

 

no no you dont want to do that. Unless you are boosted. Dont do that unless your planning on putting on a SCer or turbo in the near future. I am sure he just wants to bolt that on now so thats one less thing that has to be done. The guy who has this setup is pulling it off so he can get rid of the stuff. The Z32 is a bolt on, how ever you have to tap into the stock harness to make it work. Not hard at all. Just go to the JWT site and it will tell you how to make it work. ONly three wires, power, ground and signal wire. Thats all.

 

oh ok thank you

 

i got a check engine today....got three codes..
1) Improper shifting to first gear
2) Idle speed control
3) Ignition signal circuit

the reason i am askin this in this forum coz i know all the boosted guys are really knowledgable about this car..
