Hi Everyone,
After some time away from my 1986 Z31 turbo project, I've decided to take it to the next level of the build. I've made significant upgrades to the car including turbo upgrade, exhaust, fuel pump and regulator, intercooler, electronic boost controller, external wastegate, clutch, flywheel, LSD and a number of others. Now it's time to bring my ECU and injectors up to par. The fuel rails I will be using were purchased from Jason a few years ago and are the 11mm o-ring style.
My good friend has a 1994 sentra with a bluebird sr20 in it and he is using Fuel Injector Clinic (FIC) injectors with much success. He was very impressed with their customer service, product and performance which is why I'm leaning in their direction.
I have a few questions:
1) Is anyone using FIC injectors on their Z31? If so, what are your experiences with the product and what injectors are you using?
2) I've been doing some reading on impedance. I know that my 86t uses a low impedance ECU as well as low impedance injectors. After reading this article: http://redz31.net/pages/fuel.html it seems as though using high impedance injectors on a low impedance ECU will work fine - Low impedance ECU driving a high impedance injector should operate normally. - Is this true?
With that said, are there any negative consequences of using high impedance injectors with a low impedance ECU? Seeing as how both high and low impedance injectors are available, which injector is the better choice for my application?
These are the injectors from FIC that I was looking at:
High impedance - http://fuelinjectorclinic.com/350z-g35/IS186-0775H
Low impedance - http://fuelinjectorclinic.com/nissan...b26/IS185-0750
I noticed that these two types of injectors are slightly different in shape. Will both styles work with our vehicles?
3)Lastly, my z31 has the injector re-wiring campaign done around 2002. Will i need to re-wire my z31 to pre-campaign wiring in order to use Nistune and my new injectors properly and without issues? I did some searching and I couldn't find a clear answer. Is getting the injector wiring back to what it was before the Nissan injector campaign essential when upgrading the ECU and injectors?
one other note, my HP goal is about 350-375. Knowing this, and after doing some reading, it doesn't seem as though I need to be using a Z32 MAF with the Nistune upgrade. Are there any advantages to using a Z32 MAF even though my goals don't exceed 400+hp? Engine response, durability/longevity, ect?
I know, lots of questions. If any of you can provide any insight on the questions above, it would be greatly appreciated.
Thanks,
Remo
