Coilpacks on the 3B

[newsh]

Try sending him a msg via the link, I'm sure he'll make you one evenif he hasn't got one listed. If you read the instructions on post #7 you will see that they will fit with the 3B cam cover but it needs modifying. This is what I'm going to be doing.

GB maybe? Perhaps we can get a better price on 2 kits?

I'll be up for that, I've all ready sent the seller a message to see if he has or can make some more up. Will see what / if he replies then I'll see if he provide two discounted possibly.

Ok cool, let me know when you hear from him.

[SE_30]

Will do.

I too would be interested in purchasing this kit, please let us know what the seller reply is

Will do Barry

[quattrostyle]

looks like I'll be up for one too

[SE_30]

Just checked my eBay messages. No reply as yet but soon as there is one I'll let you lot know.

I was looking into replacing the coilpacks on my ABY and there seem to be 3 options there - Apikol @ $400, 034 @ $650 and VAG at £600... be interested to know the difference between the first 2 options.

You wouldn't need to remap as it would work at whatever the ecu was set up for.

I would like to point out that this is not quite correct.
If you do not want to remap, you also need to change the fuel rail and injectors for AAN/ABY ones.
The 3B injectors have different latency characteristics and the fuel mixture will be too rich if the voltage compensation is not adjusted, thus giving worse fuel economy than it should.

A: You have quoted selectively. I did say he would need a remap.
B: It was a joke! John's car is heavily modified. So no way would he be satisfied with a stock ecu.
C: If I wanted to be pedantic I could say that you would not need to change the fuel rail on a 3B, only that a ABY equivelent FPR would be needed to match the ABY injectors assuming that you were satisfied with the stock ABY power or a remap up to the limits of the injectors.

However, the point of matching the components is valid if someone with a stock 3B is upgrading to coil packs. Perhaps its worthwhile someone making a thread with the pros and cons of the conversion.

Not sure a 4 bar regulator is available in said form factor.
AAN injectors flow 280cc at 3 bar, 323cc at 4 bar.
3B injectors flow 323cc at 3 bar.

The common misconception comes from the fact, that the flow rating is the only important injector characteristic, when at low IPW's latency is much more important to get right for correct fuelling.

[Rocco]

you should have to install a 7A Engine FPR....but i think it is NLA

and i am not sure but if i remember correctly it works with 4.2Bar,not 4

[prj]

It's 4.2 bar afaik, yes, so would not work.

Comments on coil options

I was looking into replacing the coilpacks on my ABY and there seem to be 3 options there - Apikol @ $400, 034 @ $650 and VAG at £600... be interested to know the difference between the first 2 options.

Did you include the cost of new POSs in the "VAG at £600" estimate?

In addition to the Apikol 1.8t coilpack and 034 "HO" coil options, EFI express also offers a 2.0L tfsi coil pack option at $350 and an LS2 coil option at $425.

All of these options eliminate the separate factory POSs and coils, replacing them, plug and play with coilpacks that have built-in POSs. The ones based on 1.8t or 2.0L tfsi coil packs are more prone to failure from heat, either external or internal (internal due to dwell times). These coil packs will not likely last 150K+ like the OE coils did. However, they are only about $18 each to replace. Good on lightly modded engines but not necessarily good at RS2 levels and above (I run them on my RS2'd AAN and have replaced 3 over a 5 yr period). Running any form of cover is not recommended. Tracking events can hasten the demise of these coils (due to heat).

The 034 HO and EFI Express LS2 coil pack kits have the coils mounted on the strut tower bar and spark plug wires going from the coils to the sparkplugs. In theory (and practise for the most part), they are more robust and can handle both tracking and hp levels above RS2+ levels better than the 1.8t and 2.0 tfsi options. Some people don't like the plug wire look. Here is a photo of an AAN equipped with a 7A cam cover and a set of 034 HO coils (looks good to me):
