Reasonable source for NB coils.
 

Had an issue with a new ecu and have gone through a couple of coils.

Can I have some suggestions or links to decent/recommended parts supplier for replacements?

Are ebay offerings junk?

Best to stick with OEM?

I have been advised the coil part itself is the same as the Mitsi Evo (3?) and much cheaper when buying OEM new to get the Mitsi one...

etc....

Required to stick with OEM coils for some reason? With an MS2E on the car, Toyota or GM LS2 coils would be a solid option. The latter is a better coil, but the former might be a lot easier to get spares of down under.

I've had great luck with both Partsgroup.com and Treasurecoastmiata.com for used OEM stuff.

+1 on Tom at Partsgroup.com, calling is best.

I bought an autozone coil pack years ago, it was super pricey but reliable, and lifetime warranty. If a local autoparts store sells one with a lifetime warranty, it might be a good idea in case it ever fails in the future (for any reason). I sold mine after a few years since I went to different coils but it was solid.

Autozone huh? Didn't think of checking there, saw one on amazon but I really wanted to do the COPs conversion.

Well if you go aftermarket coils, I'd do GM or IGN1A coils. Both are powerful beefy coils, not just COP but an actual upgrade in the ignition power department.

Is OP burning coils because of non-inverted(or whatever uses "going low") spark output?

Thanks guys, will look in to your suggestions. I think i found the only spare set in the country at this point but want a spare or two anyway.

We were running some chinese toyota cops copies but pulled them to fault find a previous issue, they never ended up back on, chinese etc left a me a little unsure of suitability, though they did work fine.

Re the "Going High" ECU setting...... our tuner suggested we try tthe other way and monitor coil heat, it very quickly became apparent that the original going low setting was correct. But thanks for the suggestion, was definatley on the right track.

Alas it appears to be a wiring issue.....

I have 2 full sets, one working great and other bought but never tried it. Also have a COPs set with TSE bracket available, PM me if you want something...

Thanks Joyrider, that is very kind. Sadly I suspect the freight costs might preclude that option.....
