Help, Advice For Ignition System (failed Ptu/igniter)

[DeaN20]

Hey guys,

I have a 93 Nissan R32 Gtr that has started having problems with misfires and dropping a cylinder.

I have figured out the problem is coming from the Igniter/PTU (22020-05u00) which I think has suffered from old age/heating issues, started acting up a couple of months ago

I am after advice for how I should proceed from here, should I just replace this PTU with a brand new unit from nissan, etc. (~$650) or go with a setup that avoid this aka Okada Projects coil packs or any other alternatives you may know of?

Additional mods on ignition

Currently have Yellow Jackets Coilpacks and new coilpack wiring harness and 680cc Bosch Injectors.

Running Blackbox N61 Ecu

Thank you for any info you can offer.

Running a Blackbox?

Unigroup customer?

If so, give Yavuz a call and ask about the Morristech 6 channel ignitor. It replaces the standard one. It fixed my spark issues and have no had an issue since.

Thanks for your reply and suggestion.

Was able to speak to Yavuz and recommended the morristech ignitor and going to with that and get the splitfire coils under his recommendation.

Hopefully all works out well
