Fuel Injectors (s2k)
When upgrading to s2k injectors, do you use the
2000-2003 S2k Injectors or the 2004-2005 S2k Injectors?
And correct me if I'm wrong, but the 00-03 are 360cc and the 04-05 is 370cc?
Plus any recommendations / suggestion / opinions on other injectors are appreciated as well, just that searching around... s2k seems like it has less hassle to install.

Okay so, it seems that the ap2 s2k injectors clip onto our stock clips with no problem. I'm pretty sure fitment isn't going to be an issue... but does anyone know if the s2k injectors being drive by wire will affect the functioning of the injector?
I mean if it clips and fits, it should be okay... right?

Yeah man, a honda compatible injector is just that... a honda compatible injector. As long as the electrical voltage range used is the same (which all honda's are), it'll work fine

i didnt need to use a dremel when i put in teh rdx injectors. just needed to trim some useless plastic on the injector and swap o rings. a guy has been running the same exact setup (hes the one that helped me) for thousands of miles while boosted with out any problems

If you guys are opening up the rails (which I have done to fit RDX injectors) do yourselves a big favor and plunk down the $50 to get a 13.5mm fine reamer from a tooling/industrial supply house (I got mine from McMaster Carr), the last thing you want is a rough surface inside to destroy the o-ring during install. I first carefully expand the existing 12mm hole with a 9/16" deming drill bit then foloww thru with the reamer a very low speed and then use some 1000 grit sand paper on a wood dowl to finish the rail and end up with a near factory finish....
Also, a injector electrically is just a coil of wire (like a solinoid) and does not have polarity, how did reversing the wires cause misfires unless you cross connected two wires from two different injectors??

Depends....
With a 2nd gen TL/CL-6th Gen AV6, it will try, but the ECU seems to only be able to pull 40% max fuel, so as long as you are within 40% of stock size it can, the question is though how upset will the ECU be, p[ulling that much fuel it is going to know something is up and trigger some CEL. The other issue is that the ECU is in open loop mode (just running off the on-bord map) at startup, it will be running so rich it will wash out the cylinders walls and gas foul the oil which will destroy the engine in a fairly short time frame.
Now the 3rd gen TL and 7th gen has a much more advanced EMS which uses wideband O2 sensors and would compensate much more quickly, but will still not be happy and will have the same startup issues.

wow this is some good info NVA. What type of build was the TL that you put the RDX injectors in? A stroker?
Also, Ive been thinking about buying some high quality quick-disconnects for the existing stock and new RDX injectors pigtail wires so that if I need to go backto stock, it will be a cleaner/no solder mess. As long as the quick-disconcontnect continuity is good, do you think this is an OK idea?

If anything get the Scion connectors from toyota, the last thing you want is to kill your enging due to a faulty injector connection.

HAHAHA you guys still dont get what im saying. Again, I HAVE THE CLIPS.
The whole concern was of cutting the Original pigtail wires then wanting to be able to go back to stock down at some later point in time and it being a PITA because the connections will have been soldered to the new pigtails already.

It's not at all ghetto, ghetto would be using crimp connectors and just shoving them on the injectors or cutting the wires and just taping them in (don't laugh, I have seen it done.....), as long as the metal part is not corroded or bent it is fine to reuse it and infact helps to keep the harnesses integrity.
