dude u are gonna have to pull off the top splatic part then looks down to figure out what all u need to remove to get down to your fuel injectors.. start with the your fuel filter first hint hint .. your gonna need sockets with extenions... good luck yo...

emo236

do you know what you're talking about? I mean seriously. There's two ways to replace an injector. You can either do a plenum pull or in some places you can actually dremel some of the plenum metal off (very little) and get a socket in there. Here's a good write up on the dremel method.

You can get all of the injectors out with the dremel method. You only need a phillips head screwdriver to get the injector screws off. Afterwards, replace those screws with socket head cap screws.

We shall aSSume that you know you need new injectors, but are clueless about how to replace them.

I just realized the title of this thread is about injector upgrades. I would just pull you whole plenum. Here's a write up.

Do what I do:

Buy injectors you know are made for your car and are in fact an upgrade.
Take car to shop.
Open hood.
Wave at mechanic.
Show mechanic new injectors.
Point at engine bay and grunt loudly.

Works everytime

last time i checked, you need to a remapped fuel curve for upgraded(larger) injectors, I.E. new ECU.
so don't just go throwing new injectors in that aren't the same size without first addressing the fuel issue.

emo236

good call Rizz. IF you're doing the TT injetor mod, you'll need a new fuel map for that from JWT or ASH or someone of the like. In addition, may I ask why you're doing this mod. It won't be beneficial for you unless you're pumping some extra power...and a lot. If you're using nitrous, got a very built NA motor running high compression, etc.

by the way, guys, you can do all six injectors without pulling the plenum or shaving away at any of the metal that Nissan put there. Get 45 degree angled mini vice grips to get the screws you can't reach. I knew a guy who could do all six with this method in about an hour and a half.

I'm not doubting you, but that is something I'd like to see.

You forgot to tell him that he was going to have to open the hood to remove the top plastic part. That's the very first of many tricky steps to this procedure.
