ignition upgrade

[Clint32]

Hi, just chasing some peoples opinion on the stock ingnition system of rb engines and what you people do to upgrade them.

What power level is the stock coils/ignitor good for reliably?

Do the stock coils like to be run by a CDI with good results?

What aftermarket coils do you run and do younuse a CDI?

I will be using a motec ecu looking for a system that will handle 600hp with ease, cheers clint

also i know rb20 and rb25 ser 1 coils are the same, is there any difference between these and rb26 and the rb26 ignitor

Motec CDI with Mercury outboard coils (they are designed for CDI), bought the lot direct from Motec. Not cheap, work great, no problems, over 1050 bhp on the engine dyno.

Power FC, standard ignitor, standard coils, 625 bhp on the same engine dyno, same engine spec, just smaller turbo and cams. Cheap, work great.

from the capa website, mercury CDI coil, $71 each so just over 400 for all 6 and 1k for motec 4 channel CDI, coils are not overly expensive really as that is list price and can get for less than that.

Sydneykid do you run a 4 channel and fire in waste spark setup or have 2 4channel or 1 larger CDI? Need to determine if it is worth me upgrading now or just leaving the stock system in place, whats another grand really and i dont wont the hassles if it fails down the track
