    R8 coilpack conversion, worth it? Where to buy?

    So basically Iíve been considering upgrading to R8 coilpacks, mine are fine I think however theyíre obviously old. Iím just wondering what are the actual benefits of upgrading? Apart from the obviously cheaper price per coil... Iím running an Apexi Power FC ECU and Iím hoping to get mapped to 350-400bhp, should I stick with stock coils or upgrade? Also whereís the best place to buy the loom? Iíve been looking at this one;

    Thanks in advance✌️

    Main reason people do this is for reliability. The old coil packs are a 20 year old design and are weak compared to the VAG ones. The R8 ones are rated at something like 300bhp per cylinder.

    You can make the Loom yourself if you are handy with a solder iron. The plugs are easy to get on eBay, I bought the ones with pig tails. Use your old loom and add an earth.

    See my build thread for details.

    Also the VAG coils are cheap and easy to replace.

    personally prefer crimp joins over solder due to the vibration on the engine but I guess it’s personaly prefereance really

    If your a sparky use red through crimps and cut off the outer plastic after it’s crimped and use shrink sleeve it gives a smoother looking loom

    Hence I used pig tailed connectors. Soldered the wires

    Apparently Audi TT coils are the ones to go for, exactly the same coil just a little shorter so you can get the coil pack cover on afterwards. i've also seen people cut the rubber (boot?) on the TT coils and slide it down so that it fits into the rocker cover hole nicely.

    And regarding solder or crimps, it's proven that crimp joining cables is the way to go as soldered cables break over time due to being too rigid and with vibration (I sat through a few boring training videos years ago), barrel crimps are the best option imo as theyre oem nissan looking and easy to work with. Saying that, I still solder haha.

    can you get the male connectors of the PTU unit? I would prefer to just make a smaller sub-loom to replace it rather than butcher one up.

    can you get the coilpack loom plug so I could just make a complete loom from scratch?

    are there any preferred aftermarket brands for VAG coils?

    Here is a guy, who is popular in the facebook ca18det group. http://sxoc.com/vbb/showthread.php?5...Have-your-vote!
    As far as I remember the 115R coils are the best ones.

    Sumitomo don't make the connectors anymore but there are companies out there (mainly alibaba but in bulk) that do produce copies.

    Finjector are the only place (apart from alibaba) i've found that sell the male 6 pin connector, but connectors arent cheap especially with their delivery http://www.finjector.com/verkkokaupp...-p-489601-175/

    OEM VAG coils are perfectly fine and theyre pretty cheap anyways. I have copies from a local parts motor factors in my car and its perfectly fine, has been running them for well over two years and dyno'd etc.

    I think it’s hard to make a loom from scratch as the stuff is hard to get I managed to pick up a spare coil loom and ignited chip to butcher as the chip is really simple to gut so it stays plug and play

    I think the igniters or on aliexpress for like 20 quid so aslong as there the same design I’m sure they could be used as it saves crimping the coil loom straight to the engine harness
