Performance coils for CA?

[Swedish Mike]

Is the any bolt on ignition coils like MSD or something at the market? I need a set and it would be great to upgrade at the same time.My first thought was to use regular MSD´s with wire instead but I don´t know if it will work with ECU signal?

What are you using accept stock?

The original coils have very fast charge times. There are not many coils that would work directly with the ECU. I know that there are some Splitfire coils for RB engines that can be fitted. maybe its time for a group buy. 2 sets are good for three people.http://www.skylinesaustralia.c...16954

Yeah, why not? Good idea.

I´ve never had any problems with the stock ones but now i need 4 of them and I don´t want used coils for this engine. The OEM cost way too much new here.

Coil packs are the only way to go. I've been told by my Aussie connection that new ones are ridiculous. As are other OEM parts. Best bet is to find some good working 2nd hand. They sold me some for around $50.00 (4)Austrailia Rules! ...can't stress that enough.

We got a lot of used ones here but they are 15 years old and around 200.000 km or more...Don´t want that, I´ll figure something out. Can´t be too hard.

My friend had a newer Celica that he switched from coil packs to plug wires.Don't know if he had to use a distributor with it or not. I'll ask him about the company that makes them. Hopefully they're availible to you. They're suppose to be very good.

My thought was to run 4 coils just like stock but mounted behind the engine and wires to the plugs.Use the stock signal and all, no distributor and stuff.

Pat, I tried to call Steve. No answer. I know he didn't use a distributor and I think it was a Nology setup. He used it on his Scion Tc. Replaced the coils with external coils and wires. Wires were like 10.5mm dia. Pretty big.

[89'ClubK's]

Sorry Swedish Mike! My buddy used his factory coil packs with those plug wires.

Ok, just replaced them to save them from the heat? Heard other people do this on race engines.

Just read about Spitfire coils for CA18, ever heard of them? Can´t find them at Google, no company selling them what I can see, maybe old stuff.

/Mike

[tyrannix]

they show up on ebay occasionally, thats about the only place ive seen them (for a CA) i think some stores still sell them for RBs

might also be listed as splitfire (with an L in there)

You might try emailing the company and asking if they can special order the CA ones for you.

any RB coil will fit your CA18.....theres just 2 less coils, and they have a different plug on the coil.....but thats easily fixed

[niscort]

The specific CA18 kit has been discontinued for some time though there is still some old stock available at a few places in Aus. The RB type 001 coil pack is identical appart from the rubber boot length. The CA kit also requires a specific sub harness which uses rb/sr type connectors rather than the standard ca type. I have been told the sub harness has a backorder time of a few months.

Its quite common in Aus to externally mount Bosch coils HEC-715/6 as per this pic.

Wow, this thread interesting right now! Is HEC-715/6 the coil model?Do you know if these coils work without any boxes or extra electronic devices?I really like Bosch products, high quality.

Sorry about the Spitfire, found it on a forum and it had no L in it, Splitfire makes more sense now when I think about it. Is these the only upgrade bolt on´s on the market?

Thanks!

FET performance used to also produce replacement coil sets.

Yes they are the bosch part numbers and direct external replacement... this write up is from a guy - TurboN13(shaun)

....

4 X Bosch coils HEC-715/6 (diffence in lead connector on coil, male/female) about $40 - $60 per coil1 X Custom lead set, about $120 - $150 for a decent 10mm set.1 x Bracket to mount coils - can be any $ depending on who you know and how fancy it is, ie: mine wasfree, but i had to drill holes myself, material and bending was free.8 x Female spade connectors (larger size of the two available) for wiring - $5

Tools: (stuff to borrow)

wire stripperscrimpers / wire cutters

Intructions:

First thing would be to get your bracket made up for mounting the coils onto, and also while the caris still running with the stock setup, take it to your local leads place, and show them where yourcoilswill be sitting so they can make up/give you the correct length set for your application andstill drive your car home. This way you will have all you parts ready to go and knock the job overall at once.

Disconnect the negative terminal on the battery. Take the coil cover off of your motor, 8 bolts10mm/phillips (NB: If you have your top mount still installed remove this first, which is prettystraight forward, just look for the bolts and clamps holding it on). Disconnect the wiring fromeach coil marking each plug/connector as you go with a number corresponding to which coil you pulledit off of - number 1 is closest to the timing belt (drivers side/right side) and continues upto 4consecutively to the other end.

Sell your stock coils to someone along with all the bracketing. Mark each of your new coils withnumbers from 1 to 4. You should probably have your coils mounted on your bracketing system and workedout where the bracket will sit in your engine bay by this stage so you can work out how long your newleads will have to be, and also how short you can cut the old wiring to hook up to your new coils, oreven how far you have to extend your wiring depending on where you decide to put the coils, closer tothe plugs is prolly better for tidyness, not on top, just close.

The new coils will only have a + and -, where as the old factory coils had threewires. The thin black wire can be disgarded completely, follow where it goes and remove it. Thethick yellow one is constant remote power (+) which is a common for the coils and the pink one isthe trigger/negative (-) which has an INDIVIDUAL signal for each coil. Connect each yellow wireto each coil on the + terminal, and the pink TO THE CORRESPONDING coil - ie: when you disconnectedthe wiring connectors/plugs from the stock coils and marked them with numbers, connect the pink wirefrom the connector marked (1) to the aftermarket coil you have marked (1) onto the (-) terminal andrepeat so on until (4). * When you cut the each of the wires from the standard plugs, strip the end ofthe wire, and crimp one of your spade connectors onto the wire, then plug it onto the correct terminalon the coil. Don't cut all the wires from all of the standard plugs at once, or you won't know whichis which, just cut one wire at a time and connect it the the correct coil straight away to avoid \confusion later on, especially if you enjoying a few rumbos while you work Tape up all your wiringetc, tidy it up, put condue on it if you like, make it look pretty.

Plug the leads onto your coils and then to your spark pulgs, once again marking sure the lead comingfrom your new aftermarket coil marked (1) is going to number (1) spark plug, which once again is theone closest to the timing belt/drivers side of the motor. Repeating up until number (4) continuingto the right sequentially.

Reinstall the plastic coil cover onto your motor or leave it off it you like it that way (andintercooler if applicable), connect the battery and take it for a test toast.

Good writeup/reproduction Mr Niscort.

I'm using the Bosch coils on my CA18 (for the benefit of Swedishmike), and the ones I have, use the standard bosch injector connector, which makes the wiring more reliable and neat. I believe mine are HEC 716, but I'm using Autronic CDI and Autronic ECU.

Bring it on. :-) Certainly don't put up with faulty factory coils.

Amazing write up, even a small kid can follow this! Very kind of you.

One last question, the Bosch parts usually have part numbers starting with 0 260 or 0 280... Does this coil have a number like that? Can´t find them in my Bosch list.

Chris: Are you using the wonderful connectors with the "button", the steel wire?

I've been wanting to get rid of the stock nissan coils and go to remote forever. Posted a long time back on here (under my old user name) and sxoc, no response.Stumbled accross an RB swapping GM remote coils direct. That satisfied my curiosity.http://www.skylinesdownunder.c...85805

I actually happened onto this same bosch writeup above also. Good job!

The Bosch part number is just HEC-716, a Transformer type Coil..

http://apps.bosch.com.au/produ...s.pdfh ... du...s.pdf

You need 4x Part No. 9 122 067 011 (Connector)and 4x HEC-716

Interesting to note that I couldn't find any non-Australian references to th bosch coil part...Maybe Australia really is the center of the universe :-)

Thanks Chris! Very useful info. I called Bosch today and they had never heard of this coil, they just wanted the part number. I told them EC 715 was the part number...Sweden is NOT center of the universe, that for sure...

What´s the difference between 715 and 716? Same but 716 a new model?

I´ll try to find a Australian online shop cause I can´t find them in USA either.
