DIY: Fitting RDX injectors into a TL/CL
well, since im going boost and needed bigger injectors, i went with rdx injector. which are $37 and 410cc.
with the tips form "MoneyPit" over on V6 performance . i was able to get my questions answered and decided to make u guys/gals a diy for those who need or are gonna need bigger injectors.
what u need:
1. stock injectors from a TLS/CLS or the top o ring from them if u have a TLP
2. safety glasses- highly recommended- debris goes everywhere
3. dremel or bench grinder- dremel was easier for me to work with
4. razor blade or sharp knife
5. gloves- those who dont like to get their hands dirty (optional)
6. dielectric grease- put on o-ring so they go in easier (optional)
lets start.
1.stock injector
2.stock injector and rdx injector (the bottom of the stock injector (plastic nozzle protector? broke off on the bench and lost it) easy fix, go to ace hardware and get ur self an o-ring that looks the same and the others.
3.remove rdx injector top o-ring
4.grind off lip and hook from the rdx injector
5.should look like this now
6.remove bottom o-ring from the rdx injector
7.cut the plastic ring (bottom of the rdx injector) in one place, and take it out CAREFULLY, ur gonna reuse it
8.should look like this now.
9.grind down the plastic o-ring that u just cut off. make it half the size.
10.place the plastic o-ring in the top grove or the rdx injector
11.should look like this
12.take off the tls/cls injector top o-ring
13 place it in the rdx injector first grove on top of the plastc o-ring that was installing in step 10
14 A. place the two injectors side by side with the spraying end even on both. draw a line around the rdx injector, figure out where to place the line by looking at the stock injector and u will see that the stock injector has a high point all around it, right above the black o-ring.
14 B. OR u can put the tl/cl big black o-ring on the rdx injector until it sits flush with the plastic on top and then mark it. i move the big black o-ring down a bit so u can see where it has to sit flush, theirs a high spot right about the o-ring
15.1 is where the injector bottoms out. 2 is what needs to be cut out from what was marked
16. after its cut
17. but big black o-ring on the rdx injector so its right below the blue plastic.
18. test fit. cut more if needed.
19. your gonna need to order some scion tc injector clips so u dont have to cut the factory ones. my bro can get the clips for $5-$6 at the dealership (hook up price ). only thing is that its a special orders.
now even thought the rdx injectors are shorter than the tl/cl ones. the rdx injectors are tall enough to sit in the fuel rail and seal.

Sweet.
What are S2k injectors? Arent they plug and play and larger than the TL/CL units?

not sure about the plug and play.the s2k are 360-370cc, tls/cls are 270cc, rsx-s are 310cc and the rdx are 410cc
u can get some rc injectors for the accord and their 440cc and plug and play but their $97 or so.
some work is involved in these but a whole lot cheaper.

here are a few pics of them installed, waiting on my scion tc clips to come in
in the 3rd pic, the black ring looks like an o ring, its not, its the plastic spacer that was cut and shaved down and then put on the top of the injector, the o-ring is on top of the plastic spacer. it seals just fine, moneypit has the same setup that i have a has but over 3k on it and no leaks. also these pics are with the fuel rail placed on top of the injectors. the rails arent bolted down yet
another thing u can do is send the fuel rails out to get bored out to 13.5mm instead of the stock 12.5mm and keep the rdx top o-ring. but then u cant put your stock injectors back in when returning the car to stock.

scion tc injector clips came in (part number- 90980-11875 housing, connector). list price is $6.32 my price was $5.06. so $34 but on clips and not having to waste time to modify the oe ones, worth it
the clip fits like a glove. im quite surprised. now i need to take the wires from the stock clip and insert them in this clip.
clip and injector, match made in heaven

DIY: Switching OE clips with Scion tC clips
1. Tools: 90deg. pick, and i took a nail and grinned so it down it fits in the oe clip, ill explain when i get to that step
2. i took the pick and set it behind the blue retainer so i can pop it. worked for me, u can also try to pop it at diff points. dont pull too hard or it will crack in two (happened to me the first time)
3. retainer out
4.retainer looks like this
5. to pop out the wires, the parts thats circled in red need to go up. so i took the modified nail and slip it between the wires and the thing that circled in red. then i wiggle the wire until it pops out.
6.to put the wires into the tc clip, just slide them in and tug then back a bit to make sure that they cant come out.
7. should look like this when done properly
8. plug the clips into the rdx injector. fits like a glove
9. all clips in
10. OE clips. lost one retainer and on my first try broke one in half. no big deal since im not planning on reusing them anytime soon

Ground leads
Why is the ground lead always on the right side, not always on the right side of a given injector?
So the rear injectors have the magnetic field in the solenoid going one way, and the fronts the other.
That how it was stock, but I dont understand how that works

So yellow/black is actually the circuit. The ECU actuates with ground not the hot lead.
The yel/blk is in the '1' slot on the right side of the injector.
This is actually in chapter 24 of the acura manual....except the one they sell to us ends at 23.

Wow. What a gem. I'm doing this for a 08 TL-S and was told to come here specifically for post 18. I'm starting to connect the dots slowly but surely with my build. Thanks!!
