Coils?

[Jet 20]

just wondering if anyone is using bosch coils with their RB turbo's??

how do they compare to splitfire's?

bit of a backward step going to plug lead setup but they are heaps cheaper.

Would you be having a wasted spark setup with 3 coils or 1 for each cylinder?

Lost of high power cars run the wasted spark setup but not really any point on most cars.

Is it really that much cheaper?

[R31Nismoid]

by the time you get a ECU and so on to run it, its not cheaper.

Plus splitfires will do over 500rwkw, its been proven with stock coils time over so split's are no different

So many ppl continue to buy spitfire coil's, there not needed if you have full voltage to your standard coil's at all times.

I already have a microtech lt12s ecu, but im having ignition problems.

i will be running six coils and im looking at getting a microtech x6 ignition module to replace the standard one.

apparently they can handle more dwell.

all up the coils are $300 with mounting brackets and the ignition module is $150.

so both are still cheaper then splitfires..

[R31Nismoid]

$50 cheaper...

to bring in another element of questional reliability and so on (when factory/replacement factory is beyond adequate), its not worth it for $50-$100

So you are saying to get splitfire or stay standard??

my reliability is out the window at the moment with the setup i have so i need to try something hey..

[R31Nismoid]

Stock is $800 or maybe even more... so not an option

Splitfires are the more affordable option, and exactly the same as Nissan OEM... so just get them.

I think the JJR ones are cheaper again and near enough to the same.

[Jet 20]

what do you do about the ignition module??

my last one died a couple of months back now this one is starting to play up also.

is there a better aftermarket one available??

[RBwhatever]

I just replaced my coils with JJR ones. Fixed my missfire problems easily. 400 bucks.

[Jet 20]

where did you purchase the jjr coils from??

[R31Nismoid]

forum trader, 3/4 the way down the form - in the for sale area

bullshit

it'll only be a problem if they arent installed properly

[R31Nismoid]

not bullshit at all.

when you change something from factory (thats worked fine for 20 years), you bring in another element to track down, makes things harder to look for etc.

The more stock the car, the easier to diagnose common problems.

When you've changed everything but the kitchen sink it makes it harder.

My car uses more stock parts than ever before (when i had a RB25) and troubleshooting now is a piece of piss

[shanef]

Well its obvious that the person doing the diagnosing doesnt have clue then

Its like saying u need to kepe the std turbo, caus cahnging it for a bigger on jsut over complicates it and it could fail

[R31Nismoid]

No that's not what its like saying at all.

You can change what's needed to achieve a goal, however changing something that isnt needed, serves little to no purpose which is whats going on here altering from the factory setup

[nIsMo86]

Go splitfires or try the jjr option. Nismoid is right, the bosch setup will just complicate things for $50 less.

Why are you having ignition proplem's thou???

Go to the main power feed wire for your coil's, (will be white or white/black) see what voltage you have on idle, then rev the engine up, as your alternator charges up to 13-14 volt's, see if you get the same reading at your main coil feed wire??

I bet you dont, which mean's on full load, your getting voltage drop, and your coil's are breaking down...

Try it.

i tested the feed + wire earlier before reading this but i didn't test it while it was running.

I'm getting 12.2 volts with the ignition on but not running and the battery measures 12.4 volts.

I'l test what you said soon and post my results.

thanks for the help.

i also changed my spark plugs again and removed some fuel from the tune when off boost

i think it's an over fueling issue also compounding the problem.

but i dont have a exhaust sniffer (air/fuel) meter so i'm a bit cautious of leaning it out.

Well thats .2 of a volt lose with ignition ON, wait till you rev it up then if you loose more than 1volt, imagon that on full load, you would end up loosing 3-4 volt's to your coil's, there is your ignition break down, not the coil's fault.

Hope that help's you out.

Goodluck.
