Phil!!! You inspired me!

Be sure you take plenty of pictures of your injector swapping exercise!  Then you can tell me how to do it properly! 

I had never upgraded my SD chips so I ordered the latest version from Eric.  Then I decided to swap out the 75# injectors in my GN for 60's so I need to learn how...or get you to visit Texas and do it for me! 

After a lot of research, I have decided that Jeremy is correct and the AFX is the best wb considering it comes with an NTK sensor and has a great reputation for accuracy/reliability so I can give closed loop another try with more assurance...al tho 24.5 mpg open loop is going to be hard to beat

[phil_long]

Lol. I got you. As a matter of fact, I'll aim for this weekend. Starting on Sat morning. I have install the radiator too. 24.5 mpg is sweet. I could only wish!! And swapping out 75# for 60? The pics will more than likely be available for viewing before I make it to Texas.

[Steve Wood]

don't put the radiator in if the guy is going to have to take it out again to do the timing chain

The 75s are leaking down and need to be cleaned...60s will cover me faster than anything I am likely to go again...they started losing pressure quickly after turning it off within a couple of years so I figured I would just replace them -intelligent thing would be to clean them for less money, but age often triumphs over intelligence

Only thing I wish I did when I changed my injectors was to use KY or something else that is water based for lube..

I ended up using a little vaseline.  Other than that it was fairly easy.

Only other thing I would suggest is undo the clips that hold the injectors to the rail before starting to reef on it.

Another handy AstroGlide use!

I don't use the injector clips anymore. I've had a few sizes & they have been on/off a few times but I never felt the need for the clips. I have a stock rail-injector combo on the wall & it still has the clips. I removed 1 injector a few years back & forgot they had clips from the factory. When it didn't want to separate I soon realized the clips were still on! 

[Steve Wood]

there is no need for the clips...I think they made it easy on the original assembly.  I don't even recall what they look like.

I have used vaseline, grease out of my grease gun, silicone grease,dielectric which is the same thing, even wd40 once when someone did not have any form of grease

something that stays coated on the o rings is the best, I think...makes it easy to pull them out years later

[phil_long]

These are great tips. Mine should be easy to pull though because they were just out no more than 2 months ago. But yall suggest coating the o-rings with some type of lubricant for future de-installs?  Cool.  And you suggest leaving the rad out of the car?  I didnt think it would be in the way.  thanks for the heads up

[Steve Wood]

greasing them allows them to roll/slide into the intake and rail without getting nicked....a nick causes  a spray of gas out the top or a potential vacuum leak around the bottom....also may make it easier to remove later...yours should be a piece of cake....


but remember, anywhere you use an o ring...put a little grease on it...fuel filter, regulator lines, anywhere there is an o ring

[Steve Wood]

Lot less chance of that new radiator being dinged if you leave it off and out of the way

[earlbrown]

I use plain ole spit on my injector orings (oddly enough the same lube I use in place of astroglide/analeze)


Do normal people pull the radiator when doing a timing chain? The intercooler is as far as I go when I'm doing one.

[Steve Wood]

this is a bit different, he has a brand new radiator...why stick it in the car and chance getting a wrench bounced off it?  hell, I don't care, put it in....

If you have a dremmel with the small brass wheel you can clean the rail holes from any crud & then spray with brake clean. I also did my intake but it was off the car. I suppose if your gentle with the wheel you could do the intake on the car.

[Steve Wood]

I usually just stick my finger in a paper towel sprayed with brake clean and wipe them out...he just had them out a month or two ago...should not be any thing to worry about

[SuperSix]

Brake cleaner is a gift from heaven.
