AndyD Posted June 25, 2009 Share Posted June 25, 2009 I can only vouch from my experience just fixed my prob last week my prob was the check engine light coming on at start up and then running on 5 cyl i used the guide shown on here to bridge the consult port to get an error code sure enough it came back with the error code for coils bought a set of jjr ones $420 delivered and they work a treat no more prob. My s2 uses r34 type coils as for series 1 i would guess they would be r33 ones but dont qoute me on it. Took me an hour to install them by myself with very limited tools and im a complete noob so its not a hard job im very happy with the quality of jjr coils as are alot of others who bought them as for longevity we will have to see but for the price u can nearly buy 2 sets as a set of spitfires would cost.

wolverine Posted June 25, 2009 Share Posted June 25, 2009 the cheapest option is to silicon your existing coils. there is a neat DIY thread somewhere on SAU using a spray can of silicon (vs the more ghetto option of high temp silicon tube option which also works) Link to comment https://www.sau.com.au/forums/topic/276407-coil-packs/#findComment-4679415 Share on other sites More sharing options...
OkiM35 Posted June 25, 2009 Share Posted June 25, 2009 If your on a budget and not running a high power set up, why not just get stock coil packs?

There are probably thousands of posts on this subject (have a search in the skyline section) but here is something you can do: pull out the coil packs and give them a good clean. have a look for obvious signs of arcing. Use one of the suggestions for insulating them. Sometimes the problem is that they have trouble getting enough oomph to jump a 1.1mm gap that has grown bigger. take out your plugs and if they look new give them a clean (carefully if they are not copper) and gap them to 0.8mm. If they look at all dodgy get a set of Copper plugs NGK BCPR6ES and gap them to 0.8mm. (BCPR6ES-8 are already gapped or BCPR6ES -11 are gapped to 1.1 so gap them down). This may fix your problem. If it doesn't it will have been a worthwhile exercise anyway. Link to comment https://www.sau.com.au/forums/topic/276407-coil-packs/#findComment-4679848 Share on other sites More sharing options...
fat-lad Posted June 26, 2009 Author Share Posted June 26, 2009 plugs are new, and gapped to 0.8, and i did silicon up the coils with some spray they use when making big industrial transformers (friend works for a power company), and there were signs that they were arching out, but hey thinking at work today, we got some polyurathane adhesive maybe ill just paint them with that, just to see if it is the coils or not, but they could still be bad inside, meh, lol Link to comment https://www.sau.com.au/forums/topic/276407-coil-packs/#findComment-4681329 Share on other sites More sharing options...

RS4StagMan Posted June 26, 2009 Share Posted June 26, 2009 I have a spare perfectly good working coilpack set from my Series 2 Stagea. If interested please PM me. Only reason for the change to Splitfires was wanted larger spark energy running on LPG fuel. Is it a series 1 or 2 that you have?

Xmetal Posted June 27, 2009 Share Posted June 27, 2009 S2 coilpacks won't work in S1's due to the NEO thingy. Luke you can also try wrapping the coils in duct tape to insulate them - worked for me. Failing that, JJR coils work a treat. Link to comment https://www.sau.com.au/forums/topic/276407-coil-packs/#findComment-4683013 Share on other sites More sharing options...
fat-lad Posted June 28, 2009 Author Share Posted June 28, 2009 ian tryed the tape today, didnt work, im now thinking there either dead inside or its another issue, got the codes off it today and its 55 - normal, im started to get real dirty with this stagea now, im gonna pull the injectors off it this week and get them cleaned to see if that cures it. anything else i can try people, ahhhh also, when i 1st got the car it would stall all the time, i cleaned the throttle body and the aac but found the standard dump valve had a massive air leak so i blocked it off (made a gasket to block it) and thats stopped it stalling, but this miss at idle has always been there since owning the car but its slowly getting worse, could that be an issue? ive also checked for vacum leaks too and couldnt find any.

HELP lol I'm a little confused, are you still trying to see if the coil packs are bad? If so, the quickest way to find out would be start the car and then disconnect one coil pack at a time. If there is no change in engine idle when you disconnect the coil pack, thats your bad one. Also are these the same coil packs that are on R33 and R32 skylines? If so I should be able to track down a set of used ones for fairly cheap. Anyway let me know.

Have you rendered the bov totally ineffective? If so try to find another stock bov and give that a try.

Xmetal Posted June 30, 2009 Share Posted June 30, 2009 The stock BOV's have a really piss-poor spring in them and they rely on the vacuum to hold them shut, Luke i've got a Blitz BOV here if you wanted to test it to rule out a faulty factory item. Seriously if you've got an idle problem it has to be a dead coil.

wolverine Posted June 30, 2009 Share Posted June 30, 2009 The factory BOV's are designed to leak slightly back into the intake hence the small hole on the face. This slight leak reduces the likelihood of mild compressor surge. Something most won't experience with stock turbos on RB25DET's or RB26DETT's. Blocking the small hole may slightly improve response or increase hp by a few kw's but it is really no big deal either way from my experience but if you get compressor surge (with aftermarket turbo) relieving the hole makes the car much better to drive. Assuming there is no vacuum leak from the hose holding the diaphragm shut then the factory BOV will outperform most aftermarket units as it costs nothing to leave it alone.
