Does anyone know of an upgrade for the oem coil packs or some sort of ignition amplifier that can improve the spark especially at higher boost? There are a few systems for the ricers and also have seen a Volvo kit but really need to know a bit more technical info for the Coupé.

the only way Flea, would be to take apart an OEM ign coil & see what's beneath the potting compound, to see if the coil can handle some increased power fed to it.

I assume it comes directly from the ECU, so you would need some amplifier inbetween ? Maybe a simple voltage stepup to each coil pack ?

Depends on how the coils on the coupe work, are they triggered by the ECU but have a permanent supply to them or is the signal from the ECU giving the voltage and trigger ?

If its the latter then fitting an amp in line could screw up the ignition timing.

Try reducing the plug gap slightly if you think your spark is being blown out.

Torquemaster sells uprated (yellow) coils for the 16VT.
Maybe drop them an e-mail if they exist for 20VT engines, you never know.

I am running some amplifiers but don't think they are compatible with the std ECU.

I have emailed TorqueMaster Dink, thanks for the link.

I'm not convinced that I need it but at the moment the ignition system appears to be a weak link. I have recently upgraded to Iridium 8s which has cured the missfire but the coil packs are another weak link having consumed two over the last few months.

Is there not anywhere of adapting what the Mitsi EVO's use at all?

The TorqueMaster lot don't have anything for the 20vt at the moment.

Interesting point Begbie, I mentioned coil packs to Simon Norris and he said they have never had one let go so the oem stuff is obviously very good.

How have you defined a coilpack as letting go Flea?
Is it just by a misfiring and checking the plug to be fine and then swapping the coilpack out??

I have spares if you need any more at your current rate of use

I was looking at some iridiums for my coupe as i want to go single electrode to help the LPG burn better and Iridium do long life version of the IK plugs, VK22 but i couldnt find anywhere interested in getting me stock

Evos have a coil per 2 cylinders (at least they do on a e6). Other than that I think you may need to look to Europe rather than Japan for a solution as you would need one that is compatible with the Bosch Motronic ECUs. Something like a 996 or 997 turbo or Audi RS4/6 or similar would be a better bet IMHO.

KP - get the NGK iridium they're better than the denso ones IMHO. Barbz sells them BTW.

John

FWIW, at hig temps, durations, the central tips of the denso's are known to fall out, causing serious bore wear

rememberm, these tips aren't your usual platinum coated stuff which can break up, the iridium stuff is hard as nails

Cheers guys ill have a nosey and see what i can find nearly got some for my brothers C2 for £10 all in the other week on fleabay bu missed them

What NGK's are you running if i may ask and sorry to hijack our thread Flea

BKR6EIX,
BKR7EIX,
BKR8EIX

They are the ones i can find that obviously get Hotter(or is it Colder??) as the number gets higher

Im running BKUR7ET's a the minute and have tried the 6ET's as well but the multi electrode isnt for me i feel and singl electrode is the better way to go as you guys have found and shown

bigger the number the colder the plugs. I've used BKR8EIX with not issues.
