Wholly! I thought about doing the same deal with a dremmel tool before watching this vid, plus the same exact fuel injector cocked the whole program on mine

Hey corey, im changing my fuel rails with injectors and im thinking about deleting the water lines but afraid it will void smogs... I am also wanting to put dual air filters but only one air filter will have the chip and wire connected. Will this also void smog?

Nick Varela commented on 01 Apr 2015

Can you post a video of your intake setup?

CoreysZ32 commented on 30 Mar 2015

Coolant bypass will not void smog. Just clean up the tb fittings to make it look clean.Dual filter w/ single MAF is useless. (That green mushroom one)True dual filter w/ MAF + Dummy MAF is crap (Old JWT setup)Go dual MAF with Selin plug-in. It's hidden and runs great, so shouldn't be an issue

+CoreysZ32 was just wondering because of the gap between videos. Hope to see you more videos in the near future.

so I got a used set of new style injectors in the fuel rails to replace my failing old style injectors what i did to get out the first 3 is to put the rail upside down in a vise, place a 7mm socket over the plastic pintle, and give it some light (as light as i could) taps on the socket until they popped out onto my cushion of rags i had created to catch the injectors. now the plastic pintles were destroyed, but thats alright because i bought some new ones, but i just want to know if i hurt the injectors this way. im going to press the last 3 out btw

khan brah commented on 23 Dec 2014

also that injector wiring video would help out a lot! where is that at?

Any info b appreciated

@ummmmmmmok If I was you I would only bring my Z to a Z specialists. If you do not you may end up in a bad situation with someone that does not know what they are doing. 900 is pretty cheap for what you need done. When taking apart the entire top of the motor and you need to know certain stuff before doing this pull. Which most mechanics do not know. Go to a Z specialists and you will not be sorry. If you do it yourself be prepared to spend more than 900 becuz you are going to break something.

Cesar Davila commented on 09 Jul 2011

I have huge question, my '90 300ZX motor shakes when I start it and it won't stop unless it moves, some mechanics told its two of the coils and a dirty or bad injector, does that sound like it?? And I found fuel injectors, but too expensive for me right now, but I found a Infinity J30, which has the same engine as my 300ZX, do you know if the injectors on the J30 can fit on my 300ZX?? I need help with my car bad, no mechanic wants to mess with it, because they say the car is complicated :-/

dustyroads13 commented on 13 Jun 2010

yeah im about to do a swap on my own with two na engines hahaha im poor but I got a 300zx! tt or not im still okay with it... first car and in over my head but thats okay... some of the window mouldings or whatever you call them are torn up and water leaks into the doors and widows. how would you go about fixing that? the big problem with that is the actualy window strip in between the triangle glass and the driver window. massage the O ring hahaha

Isaiah Trotman commented on 02 Jan 2011

Wooo thanks alot man!! i was bought to pay the Nissan Dealership $954 dollars just to replace two fuel injectors. i figure for that price i could replace all six myself and have some spare change left over lol.. i had read up A LOT on how to replace them, went outside to my 93 300zx and did a quick look see, and it seemed alot simpler than $600 worth of laborl. ol, but your video just made it seem easy as pie. Thanks Mr. 300zxGuru, :)

Let me first start off by saying I'm a big fan of your work and videos. One side of my exhaust is puttering while the other side is running nice and even. Do you think it's due to misfiring? Should I unplug each injector one by one and see if my rpms drop? I'm also thinking about cleaning my electrical connections (CAS and PTU) what do you think?

Canadian300ZXTT commented on 03 May 2009

Well my car only has 96,000km on it so I guess the valve cover gaskets will be good. So I'll just get the injector changed the dremel way. I had a shop around here quote me $300 to change my injector by grinding the plenum, not including the injector, does that sound like a reasonable quote?

ummmmmmmok commented on 28 Jun 2011

How difficult is it to do this for someone who doesn't have much experience? I have a bad injector on my 90 300zx and the mechanic says it's going to cost $900. I have friends that have experience, but before I ask, I just want to make sure you don't need to be a "super-mech" to do this.

adrian diaz commented on 25 Jul 2014

I have a 92 300zx and I got the 96 injectors, so i installed all of the injectors and ll fit just fine except the number six injector, it rubs against the fuel rail and i cant connect correctly to injector. Can I use 96 fuel rails on my 92 motor? same fit? Thanks

Canadian300ZXTT commented on 02 May 2009

Hey guys I have a bad injector #6, but all the other ones are still good. They are the stock 370cc injectors. I was told I can grind the plenum to get at the one injector so that I don't have to pull the plenum. Just wondering what your thoughts are on this method.

The300ZXGuru commented on 02 May 2009

If I were you I would try to get the plenum off and then while you were in there go ahead and swap out the valve cover gaskets. Because they are usually leaking after 100,000 miles. But if they are not leaking then I would try and do it the grinding way.

Robert Wolfe commented on 15 Jul 2014

The fuel injectors can be replaced without removing the plenum. You'll need to grind the plenum down to make clearance to reach the injector bolt. It works great and you cannot see the ground out portion.

Part two - I'm not a pro but was able to take it out easily with no struggle except with the worry of stripping the Screws head.
