front bank injectors

[frankendat]

When looking under the hood of a 2001 Nissan Maxima and injector/coil cover plate, which ignition coils are in the "front bank" and/or are there markings or design differences that identify whether a coil/injector unit is a member of the front or rear bank.

Thank you

The three closest the rad and grill????? OR if standing at the right (passenger's) fender looking at the engine, the three coils on the right OR the side the alternator is on?.

Information from the website that suggested the Maxima coil/injectors: "2001 maxima coils are drop in with perfect fitment, do not NEED a mounting system unless you feel like it, has a built in ignitor so no external one needed, they are triggered by 5v so NO MORE PLUG WIRES!!...you need to use 4 coils from the FRONT BANK of the maxima. If you go to a junker you need 2 donor cars."

I have located a couple of 2001 Maximas, but haven't figured out which coil/injectors to acquire. The Maximas are 6 cylinders not 4 cylinder. My best guess is that you need 2 donor cars, because there are only 3 of the correct injector/coils under the engine cover, the other 3 are at the back of the engine and would be difficult to remove. For some reason, when I read a total of 4 injector/coils were necessary from 2 donors, I thought 2 injector/coils from each of the donors. But, my new theory is that it is 3 injector/coils from one donor and 1 injector for the other (although I would take all 3 to have spares).

Anyone that can confirm my theory?

No idea what your plans are. There are VQ30DE and VQ35DE

 

 

VQ30DE......

22401-1P116 spark plug Qty, 6

 

22448-2Y000* coil RH Qty. 3

22448-2Y006* coil LH Qty. 3

 

* the last two digits are the Distinction Number. 00-19 signifies a similarity like two carpets the same but for the color. So I imagine they are basically the same but why RH and LH ????

One thread that I have be using for reference is here: http://www.ka-t.org/forums/viewtopic.php?t=60105

It is the website that provided coil on plug identification confusion, and new to me term "Front Bank"

In my continual goal of getting much for little, I have been investigating ignition timing to increase mpg and maximize engine efficiency. The link I posted is a coil on plug setup that uses a Megasquirt. The Megasquirt is a fine device, but spendy. The methods of using a stock ecu with either an affordable Megajolt and/or a Dog Tuning converter explained here http://www.ka-t.org/forums/viewtopic.php?t=62837

 

That is where my head is at, investigating an option until it is proven not cost effective, over complicated/unreliable, or any other disguised difficulty uncovered through investigation.
