You can run individual coils no problem just using the OEM dizzy triggers, although there is more cost as you have to buy extra coils depending on your ignition setup. I know what you mean, we pay over the odds for a 5E here unless your lucky to find a deal, some people even buy the whole car! I've got a Motec to fit mate, I spent a lot of time researching into what ecu to run, I narrowed it down to Haltech or Link that was reasonable cost wise and still provided good enough control for what I needed. Or if I wanted to spend big money then Syvecs or Motec, but it just so happened a Motec cropped up at the right price. There's no doubt it will work for sure, its just a case of configuring everything to work, which I'm sure if your tuner is a dealer he is more than competent enough to get it working for you
