Hi I have an RS2000 mk5 engine to my sierra with the electrical of it...
I want you to help me to my question.
Will it work If I put honda s2000 coils?
Will I need to change the ingnition module or with the same wiring by adding two more plugs for the extra coils will work?
THANKS

 

As it was coilpack to start with, you just need to add another two wires to each side of the coil circuit, so 1 feed becomes 2 feeds.
On the std coilpack centre is Live, this will need to go to all 4 coils, then the left terminal will be the negative(ecu switched) feed to cylinders either 1 and 4, or 2 and 3, so take this to the relevant new coils.

I really thank you tabetha...Another question...The centre is + the left is - the right pin? what is that?

 

Assuming it's got a standard ford coilpack, this will have 3 terminals, the centre terminal will be POSITIVE + 12 VOLTS, , the terminal to the left of this goes to the coil to the left of the pack,(the coilpack is two coils moulded together), the terminal to the right goes to the coil to the right.
The coilpack uses what is called wasted spark, and the coilpack is 2 coils in one pack, one side of which feeds cylinder 1 and 4, the other side will feed cylinders 2 and 3.
The terminals either side of the centre positive one, are the negative pulses that come from the ecu, so a spark occurs in cylinder 1 and 4 at the same time, and cylinders 2 and 3 at the same time.
A lot easier to explain with a diagram, just pm me your email and I'll draw a sketch for you, it's very easy to do.
My only concern would be over heating the drivers in the ecu however, as it will now have nearly double the load.
4 seperate coils will give no advantage whatsoever at the rpm reached by your engine though, so is a bit of a waste of money and time, it tends only to show a microscopically small benefit at mega high rpms, like bike engines go to.
