Changing to coilpacks...

[Robatron]

I have been having a think about this one and I reckon that for more power in the future that coilpacks are a much better bet than having my dizzy...and less rattly!

Did Minhea ever release the cheaper alternative to this or do I have to get the ABY wiring loom, ECU and god knows what else?

[Acidburn]

I've also been interested in this option (espec considering i've just broke the dizzy cog so thats being changed) I think I did see a comment about changing to coils as i'd also be interested in this providing it ain't too involved (i.e. full engine bay loom change)

I am doing this with my project,

I have the ABY loom and ECU, but i hear its a right pita

thats pretty involved stuff...when does this get to be a critical change hp wise?

[4WheelDrifter]

Sell your 3B and get an ABY. That's the easiest way.

Tom ran his dizzy ok up until ~470 bhp. I think it could've done with a better coil though.

Dont you just know it

In terms of the coil pack part of this 3B to ABY conversion, I think you will be WAaaaaay ahead if you use 034's high output coil system (5 remote (firewall) mounted coils). The reason I say this is because to use the ABY (or ADU or AAN) coils, the cam cover is different. With the 034 high out put coils, you run 3B-type leads from the coils to spark plugs so that part is more or less normal.

The 3B (or 7A) head can be modified with a bracket to mount an ABY/ADU/AAN hall sender ("cam position sender") behind the belt driven cam sprocket. You will need to buy a real CPS with the bracket as well as develop another bracket/mounting boss to mount the CPS unit.

What sort of performance gain would be possible with the change over, just the 10bhp and the additional torque?

[Robatron]

No entirely....

The performance gain is actually more noticable when pushing higher power, i.e. the way the 3b's are made I think they will push roughly 450bhp before misfiring (or shooting a plug!) where as the coilpacks can handle much more power.

So changing to coil packs is more about pushing the limit of the tunability of the car.

If everything I have read is correct, then I should have no problems pushing 380-400 bhp with a dizzy and HT leads which is fine by me.

I seem to remember that Tom's 3B was pushing IRO 400bhp on a dizzie?

[s2driveruk]

sure my credit card will melt long before 400bhp
