Using 2.0T coil packs on the 1.8T

[xdewaynex]

Ok great, shouldn't be any issues then. Thanks for the write-up!

Not a problem, I know its kind of confusing where I switched what harness it was in the thread, sucks I cant change the title. Just glad to hear people are still using the write up. My swap is still going strong.

[ECS Tuning-Audi]

Thanks for the clarification Jason. I'm completely cool with splicing and soldering I guess I just wanted to be able to follow along with xdewaynex's write up but use the Jetta Harness instead of the ATW harness.

No problem!

Since your vehicle doesn't have an ICM you can skip the whole delete part. So all you should need to do is rewire the plug into the rest of the harness.

I'm in a 99.5, AEB vehicle so unfortunately mine does have the dreaded ICM..

My mistake, I confused you with U_know_me as he mentioned he has a 00 A4. I owe ya a soda!

I know, I know... Let the dead thread bump jokes ensue. I just figured I'd update here rather than start yet another thread on the matter. (And at least you know I searched.)

I am asking because the links I need in this thread are all dead ends at this point. Just the clarify, I bought coils p/n 06E905115E (red top), and harness p/n 1J0971658L. That is what I need for this pin out, correct? Car is 1999 AEB.


Harness should be in tomorrow. Coils came today.

Running MKV FSI : 07K-905-715F With (AWM motor) GTRS around 21 psi ( NGK BKR7EIX-11 gaped .43) Runs great!(1,000 miles on them) I got them on amazon 17 bucks, if you have prime free ship just have to find the prime seller.

[Koldham]

We carry those 4-wire plugs for for $11/each with 4 new pins.

We can also supply them "flying lead" style with wires already crimped for an additional $4.

Please feel free to PM or email me.

whats the part number for those plastic plugs. its in one of these threads around here but i cant find it again.

[RallyeBourne]

Here is my final result.




I am stoked by how it turned out. Runs so much better. And looks badass.

Not meaning to nerco here, but I've read all 6 pages and also a few other threads and am still a little confused..

I would like to upgrade to the 2.0T coils from where I am now with just the stock 1.8T coils. I have a 1998.5 A4 1.8TQS so a AEB engine and harness.

From what I can make out, I have a few options:

1) I get a Jetta 1.8T repair harness with the 4-wire ignition coils upgrade and just replace my old/damaged coil pack harness and call it a day. (which is found here: http://store.034motorsport.com/harne...wire-coil.html)

2) Upgrade to the ATW harness and coils and then upgrade to the 2.0T coils?

3) Upgrade directly to the 2.0T coils/ related components with this kit?...: http://store.034motorsport.com/coil-...fsi-coils.html

I'm open to making my own sort of harness, I'm just sort of lost with all the options and would really just like a sort of straight-forward list of everything I'd need to do either option 1, 2, 3 or whatever you all throw at me. I'd like to approach this the simplest way, but if there's a much cheaper way, I wouldn't mind hearing it.
Much appreciated!!

[Davdraco1]

I'm AWM so they are drop in for me and I've got 2.0 coils. From what I understand. Go with the 3rd option. Then you just need the coils and done.

[walky_talky20]

Options 1 and 2 are the same thing. You can get a new harness or a used one. Your choice. Then you can use 1.8t coils or 2.0T coils. Also your choice. For 2.0T coils you can get adapters for fitment or not. Again, your choice.

The third option is to just adapt your current harness (in place, without removing it) so you can run 4-wire coils (1.8T or 2.0T). This is fine if your harness is not compromised (aka: roasted). But if you want to renew your harness at the sane time, then option 1 is ideal.

2.0T coils are taller (ostensibly requiring adapters), cheaper, and provide a higher output voltage potential. This makes them able to deal with larger spark plug gaps, should one desire. They also seem to provide improved reliability.

They are also what all the "Cool Kids" are running now. So, if you want to hang with us...<sunglasses>...you should probably get some. (j/k...but srsly, everyone's doing it).

[Mad Cow]

Only thing I don't like about 2.0t coils is the front one is too tall to fit under the stock engine cover. Since I like covers I had to trim mine quite a bit and it looks kinda weird.

[walky_talky20]

You can space up the cover mounts a tad with a washer or 2...if you're into that sort of thing. ;)

I agree.
Instead I went with a "coil cover" that 034 Motorsport sells. It still looks nice but instead of 3 quick-release fasteners it takes 4x M5 bolts to remove.

[Mad Cow]

But then there will be a gap between it and the t-belt cover, I could try it though in case it ends up looking less hacky than what I did.

The 034 cover is pretty, but I don't feel like spending $60 on a (very nicely) bent and cut sheet of steel.

Or you can save a bunch of money and buy a straight harness http://www.europaparts.com/coil-pack...j0971658l.html which will require either a little soldering or crimping.
I thought the ECS cover plate was a nice addition when it was $60, now its $100
So you can do this for $63(harness) +$80(coils) plus adapter plates.

Noob question...looking at option 3 via the 034motorsport link, is the appropriate adapters for proper fitment included?

Additionally, if I were to do the third option, and a fair bit down the road decide/ am forced to replace my harness, would it be possible to salvage an majority of the parts from the kit and simply 're-adapt' the replacing harness?? I imagine just going with option 1 and advancing from there would probably be the cheapest/ easier route, no? (Also thank you for your prompt response! )

[walky_talky20]

I think option 3 is a silly waste of money. If you want to do it right and yet not spend more than necessary, I would suggest:

This harness:
http://www.europaparts.com/coil-pack...j0971658l.html

These coils:
http://genuineaudiparts.com/parts/in...&siteid=214407

These adapters:
http://genuineaudiparts.com/parts/in...&siteid=214407
Check out said adapters here. http://www.ecstuning.com/Search/Site...658L/ES283074/

Total with shipping to my house? $172.17 USD
Total if I bought from ECS? $189.52 USD

Way less than the 034 kit at $266.57 shipped. And you don't have to use your old crusty harness, or have a pile of adapters hanging out in your engine bay. Yes you will have to crimp a couple wires. It will be devastatingly difficult. (not really)

[walky_talky20]

There are only 4 wires per coil. 2 of them are grounds and 1 is power. These are common between all the coils, just splice them up.

So the only potentially tricky bit is the single trigger wire for each coil. 4 wires total that are specific, and there are plenty of charts and such to look up what goes where. Or you can just ask us "Hey guys I have these 4 wires on my car, which one goes to what cylinder?"

[b5a4erik]

Here is the DIY I used: http://www.audizine.com/forum/showth...WP-upgrade-DIY

I have r8 coil packs and I think the AWP harness. Also had to do a ICM delete.

[$teady$upreme]

Reviving an old thread. I forgot what's the best plugs and gap to run for GT28RS with 2.0 coil conversion?

Mind you car is running slight rich.

Thank you very much in advance.

[xdewaynex]

Im still running the NGK BKR7E plugs with about a .040 gap. 22psi on a Frankenturbo 440cc setup.

Perfect just ordered. Yah i remember vivdly i was running 0.040 too, thanks for the double assurance.

[xdewaynex]

No problem. .040 seemed like a good number to go with and Ive never had a problem in the last few years since I done the 2.0 coils. Ive been wanting to change the dwell time for the coils, but I honestly dont know what to switch it to.

Would this harness not work?

https://www.ecstuning.com/Audi-B5_A4...ion/ES3082311/

ECS also has a nice write up on how to connect it here.

http://bd8ba3c866c8cbc330ab-7b26c6f3...llation_r3.pdf

I also wonder if you could use that wiring diagram/setup to simply change the connectors appose to the whole harness.. assuming the stock harness was in decent shape.. if you wanted to be really cheap

Yes that harness now appears to be THE BEST option assuming its quality is good. It wasn't available until a month or two ago (Walky's post was 8 months ago).
Chances are the stock harness & connectors aren't in the best shape. i.e. cracking wire insulation, broken coil pack plugs.

[Avant Nate]

Its crazy how the price has jumped on the repair harness at some vendors. $55 at Jim Ellis http://www.jimellisaudiparts.com/pro...J0971658L.html Seems like its out of stock most other places, maybe discontinued.

[Rmartin]

Yup, seems like a lot of items are a little over priced if you ask me. Anyway, the harness from ECS has free shipping and you get the supper cool crimping tool that goes with it!

Slightly confused. I've read a number of threads so a lot of the info has been mashed up together in my head. I have an '01 that just had a coil pack go out. I had a spare good one from when I last replaced all 4 so I'm OK for now but since they have around 50k+ miles I know I'm on borrowed time.

I can get these:
http://smile.amazon.com/dp/B00KWGK0W...=IIHTPG3XBHRYT
coil pack # 06H 905 115 B
and gap BKR7E plugs to some where in the mid 30's and be good to go?

Car stats are in sig. Mainly interested in running slightly larger gap for smoother idle I know there is no real power gains to be had. My factory harness is still fine so if I had to buy a new harness or wire in new clips i'll just replace my packs with what ever OEM packs I had before

You have an 01. FSI coils are plug and play for you. No need to get a different harness

[bruejones]

I put those coils on my ATW and it runs great now...no misfires but I like those plate thingys...ECS has a solution too but it cost$$$$$

[juxsa]

Awesome thanks guys just put in my order

[juxsa]

Well I gapped the plugs to. 040 and idle is smoother than ever. There has always been a slight hesitation around 26-2700rpms and that's gone too. Great upgrade to do when it's time to replace coil packs

Bumping this thread to ask - The ECS kit has been out for some time now and was wondering if anyone could compare it to the kit that 034 sells. https://store.034motorsport.com/harn...wire-coil.html

The ECS is definitely more price friendly but curious on the quality, opinions, etc. Are these kits better in quality that the oem repair kit Avant Nate listed in post # 231?

[kruftindustries]

They are both the same in concept but the 034 uses a different connector and plug to go to the body. I think it was deutsch. the ECS kit has a cheaper connector there but it works fine. Also, the ECS kit supplies a worthless wire tool with the kit, I would suggest getting the proper "W" crimp tool and an automatic stripper to make this and other projects in your life go more smoothly

[b5a4erik]

I've got the ECS inbetween plate and I think it looks sweet and more importantly fills that gap well.

[SN95Audi87]

Has anyone used the coils by "OriginalEquipment" that ECS sells, or your better of buying oem 2.0T coils?

[Seerlah]

Not worth cheaping out on such an important item. If one craps out, you will be riding on one less cylinder. 2 crap out, and motor may not have enough in it to even keep running.
