I did a search, found nothing

Why does my lancer come with only 2 sparkplug wires? Matter a fact, where are they. My sentra had 4 and they where easily found on the engine block next to the VC, can somebody explain and help me here?

 

Plugs are right on top of the block. Where those rubber things are.

the 2 plug thing, I just can't remember exacly why

 

its not 2.. Its 4.. but you only need to change 2.. is that what you wanna know? well.. i really dont know to.. thats just what i heard.. coz RRM is sellin the magnecor ones i think and they said only 2 is needed..

 

Here's the deal.

We have a DIS system. Distributorless Ignition System. There is no distributor (duh). The electricity goes from the ignition to the two coil packs, and from there it goes into:

A) the two plugs attached to the coil packs
B) the two plug wires that go from the coil packs to the other plugs.

There are 4 plug wires, but you usually only replace the two smaller ones.

To illustrate:


Going vertically, you see plug wire (red), coil pack, plug wire (red), coil pack.

Kapiche?

 

yeah, i see... my next question was 'where is the distributer/rotary cap... but u explained that. Why did mitsu opt for not putting one, i mean i was just dumb founded cuz i thought all cars had a distributer/r-cap. Also why did you put a breather on the right side (top) of your VC cover?

 

A) I think it's just a newer thing that is catching on. I'm not sure if a distributor or DIS works better.

B) Not my car (stole the pic from TURBOit because I didn't take pics of my plug wires yet), but he put it there because his setup doesn't have a need for the extra air. NA cars can use that air and put it back in the intake for reuse, but turbo cars don't need that, so you can just throw on a breather to vent the excess air.

 

actually a friend of mines put a breather on his VC cover of his sentra (non-turbo) because it breaths better. The tubing that connects the VC to the air box just shoots the fumes up the filter (which makes it dirty and perform bad over time), but by putting a breather (doesnt shoot to the air box) it doesnt wear down the filter in you air box, and makes the fumes exist the VC breather out the car hood more better.

 

Hmmm. In our cars, the recirc. enters the intake hose right before the throttle body, so I don't think it bothers the filter, but I might be missing your meaning. I don't think it's mandatory to have, but it probably helps. You could be right about the breathing better, I'm no expert.

 

oh ok, im just trying to get some info down on the mitsu engine, cuz i know alot about nissan engines.

 

Ok, wow, lots of issues here. First and foremost, DIS are much much better than a distributor. There is no contest. A distributor is a moving part and is less dependable than a fully electronic system. DIS systems are certainly not that new either, they have been out for a number of years.

Also, the main reason for recirculating air back into the intake is for emission purposes. Its "basically" recirculating "exhaust" gas back into the system to introduce to another cycle of combustion. It is almost purely an emission tactic.

 

Also where is the ecu, cant find that lil thing

 

Check link out, for ecu.
