Hello guys another question .

I'm looking at upgrading the ignition system on the R . Only reason is that on the dyno when we up'edthe boost the plugs lost there punch and we had to close the gap to bring it back in line .65mm I think ?

I was wondering what could be done to upgrade the system with out adding individual coil packs.
I.e. Better plugs , leads , coil, inline capacitors ( lol) etc.
Just wondered what they high boosting guys use on there engines .

Thanks

One small thing you can do to help with ignition is to "index" your spark plugs.
Before installing spark plugs, use a marker pen to mark a line up the insulator to show the position of the spark plug grounding electrode (the bent arm bit).
Install the plugs and see where the marker pen line is, it is best if the line is facing towards the inlet (and better if between, in the middle of the inlet valves), as this will keep the rich fuel mixture from flooding the centre sparking electrode.
Indexing can be done several ways:
One way is to get a bunch of spark plugs, mark them all on the insulator and test fit them for position. Use the plugs that line up correctly with the inlets and evenly across all 4 cylinders.
The other way is to use 'indexing washers', these space the plugs, allowing the electrode to face the correct way. NOTE: This method will change the depth of the plugs in the cylinder by whatever the thickness of the washer is in comparison to the other plugs. That is: all 4 plugs will probably be at different depths due to the difference between each washer thickness.
The benefits of indexing are minimal but if you want perfection, this is one factor.

Indexing is a good tip, don't see it done much .
Upgrade roots for standard ecu are limited, standard ignition is good if in top condition so many can get away with new oem coil and leads . oem leads being best match to oem coil and amp.
oem probably close to limit of constant good results once over 1.7bar
some options:
hks twin power module (they do one for distributor ign, not specific gtir kit though)
msd or crane etc coil and amp kits.
None are cheap, making most of oem system is cheapest, hks is a tidy bit of kit and does work.

Have a look at the MSD 6aL and blaster coil. There pretty cheap second hand.

And can also remove the factory transistor which normally gets effective by heat.

I have a hks one I brought off bob many moons ago but never used it. Must have been removed from an R. I will dig it out if you want as would sell it cheap.

Looking for some advice on this too, I will be using the EMU ECU and i don't really want to wire it back to the distributor, Was looking to go for a coil pack but was wondering what everyone uses or recommends.

With emu you can run separated coils mate only for this you might need to put crank sensor. I'm quite interested in EMU myself let us know of progress mate.
Anyway if you're on facebook there is a group called ECUMaster Tuning and Tips they might help too
