Rb26 500rwkw+ Coil Packs Issues

[DannyzGTR]

Just would like to know if ppl still using spiltfire coil packs or what is better?

I started to get miss after 7krpm install a hks twin power (helped) then the miss came back after a few weeks, does it all time same

Rpm range. New plugs fitted and gapped to .8 and spiltfire coils about 6 yrs old and about 30,000kms on them. All brand new engine harnesses...also boost is about 22-23psi

[GTRPSI]

E85 or?

What plugs and heat range are you running?

Was it OK for a while and just started or has it been happing from the start?

Have you checked the Spitfires for arcing?

[GTR_JOEY]

Is it missing when hot?

use copper plugs at 8 heat range from memory, Check coils, make sure your alternator is pumping out decent amperage, flog hks twin spark off and buy Morris tech igniter

[DannyzGTR]

E85, 7 heat range, never happened like this before. Its been warm weather im thinkin i need 8s. Sounds like more than one.

[sky30]

close gaps on the plugs a little more, and make sure there all same gap spot on.

.7 gap would most probly solve your issue

[Dose Pipe Sutututu]

gap it down to 0.6mm

[crashsvg]

with that power you should be using heat range 8 not 7...close the gap and try again..stock ignition system is good to around 28psi so at 22 you should have no problems

[DannyzGTR]

.7 solve the problem. What plug is there in 8?

[etang789]

may be you should try the LS2 Truck coils http://www.sau.com.au/forums/topic/440409-ls2-coil-on-plug-mod/

For those of us that missed the bulletin what is wrong with the HKS DLI II ?

[Piggaz]

That hunk of junk cost me two sets of coils. Ditched it along with the factory and used the above mentioned ignitor and issues disappeared.

The factory ignitor is an electrical bottle neck.

[GTR_JOEY]

That and it's more expansive and harder to get then the Morris tech ignitor

Paul's making 480rwkw with no more then spitfires and a Morris tec ignitor.. I'd be right in assuming that the plugs are copper, heat range 8 gapped at .8 (I may have put the last set in?)

This business of reducing the gap of the plug down to nothing and reducing spark size is a bandaid fix and simply ridiculous

[Roy]

How was it cooking coils? I was looking for one just for the plug in simplicty. May need to change that thinking

[Piggaz]

I can't tell you how but I had a new set of OEM and a set of split fires both kick the bucket within 3-4k kms. Ditch the lot and it's all good.

Joey had issues at 400 rwkw, put the ignitor on and done.

I've sent a few of these around the country and on every car the ignition issues disappeared.

[Roy]

Good to know. Cheers

What price in this moristech box? Can you get the standard gtr ignitor plugs so I can make a patch looms for it?

[GTR_JOEY]

Like 350 from memory.. Paul will know

[NYTSKY]

I know of at least 8 GTRs with 500awkw+

3 GTRs with over 600awkw

3 GTSTs with over 500rwkw

All with Splitfires and NGK copper plugs. Plug gap is critical and all plugs must be spot. The difference between a .6 and a .65 gap is noticeable when you start going cranking the boost.

Where from? My ignition system was starting to break down at 2 bar so we gapped down the plugs a little. Wouldn't mind trying this morristech out
