Ignition Re-Wire

Hey all.

I would like to re-wire all the wiring to the igniter packs as the wiring is so old and on the turbo side I have plugs ect were the old twin turbo set up was.

Of there any sides to this or good tips any could give? Or maybe know anywhere reliable I could take it to?

On recommendation from Sam at TDI

I'm changing all of mine to AudiR8 coil on plug, much better spark energy than the stock coil packs, and getting rid of the igniter as the F con will drive the signal.

wiring will be out of the back of the head along the firewall.

What Engine / ECU combination are you running? 1ZZ coils can be a cheapish way of deleting the igniter. You would need to make a loom and a retaining bracket though.

I have just bought new coil OEM packs costing me hundreds so I'd like to continue to use them. The R8 coil packs fit? They run off a 4 pin connection?

I am running a GTE engine, single turbo on syvecs.

Thanks

yes 4 pin

..using Audi clips & Pete's making up a custom loom

Well unless you can get the actual connector pins at the igniter (unlikely) and new coils clips and connectors (these are available) you are going to have some old wire in equation. I've rewired an OEM ECU from the coil triggers to the ignitor and from the ignitor to the coils on a real problem child of a Supra. It's a hell of a lot of work. If you are going to the trouble of ripping your loom apart, remove everything you don't need from the ecu to the redundant items and replace the injector wiring and all power supplies both 12v and 5v. Or better still just build a new loom from scratch.

Ah ok, well thats a hell load cheaper than OEM coil packs.

Well its juts from coil back to igniter I wanted to rewire..

A lot cheaper.......full set of new R8 coil on plug £170

and more spark energy.

ive always been told the stock oem supra ones are the best to go for..

I was getting spark blow out at 1.6 bar, and my coil packs are 16 years old now so Sam at tdi said that the supra coilpacks are around 30mj of spark energy, the newer designs of coil on plug are 70mj plus for direct feed injection engines...so bigger bang!

Mine are 120mj (They have External Heat Sinks ). They are from a Chevy Truck and were about £150 with the connector kits landed from US for 8. Made by AC delco. They do need a HT lead though which may put people off.
