i have just changed to splitfire coils, and it is still recommended to keep the plug gap to 0.7 or 0.8mm. On the street it ran fine at larger gaps (i tried up to 1mm) but on the dyno it missed badly up top of the rev range.

as a point of interest, with plug gaps at 0.7mm, i gained roughly 3rwkw on the same dyno in the same conditions since changing the coils to splitfire, nothing else changed. Its probably insignificant, as i didnt do numerous runs and take an average, but its nice to see :(

oh, to answer your question, i would recommend it. Im only running 17psi, and the stock coils would give me a few misses every now and then, but with the new ones i havent seen a miss yet. It did also feel like it ran stronger after i changed the coils. May be Placebo effect tho!

Also if yours is an early series 1 33, the coils will be getting pretty old now.

Yeah, mine missed like crazy once I got past 15 psi, but I found all the coils were cracked.

Splitfires are a good upgrade, and I saw an improvment of around 5 - 8 kws or so, and the power feels a lot more solid (and I can actually floor it now....)

you can get them for ~$700 thru greenline or nengun or the like. Or if you want them ASAP Horsepower in a box should have them on the shelf and get to you in a couple days, but for around $900 maybe a bit more -not sure, check the website. High octane racing in NSW should have them also.

pretty sure price is same for series 1 or 2.

as far as i know, the splitfire series 1 and 2 coils are exactly the same coils, just the plug is slightly different, so its possible you could just use the correct loom/plugs with either coils on s1 or s2. correct me if im wrong.

guys,

is it worthwhile to upgrade ignition coils to spitfire when running about 18psi or r33 gtst? any feed back would be appreciated!

not really.

My car is fine and im over the 300rwkw for the time being.

I have no issues at all.

MY suggestion, put it all together and then see if you have any problems.

THEN spend the extra $$$ on getting them. That way your not spending money if you dont neccasairly have to

And some food for thought...

Whether the splitfires are actually better... who knows.

Remember your replacing 10year old packs with brand new ones, so of course they are going to work better

im of the belief that if money can be better spent elsewhere, then it should be... if not save that money incase something else breaks.

I dont mind talking from what ive found out of my own car which ive spent a lot of time/money on... some i wasted. And i'd hate to see others do the same

      Started sifting thru my brakes to decide which ones I will run on Clem   Made me think I should just put them all on Silver...for when brake fade just isn't an option   Should be able to bump rotor up from 343x32 to 348x36 off Supra. Not sure if the Supra annulus is right for the Alcons or APs but trying g to find a used Supra\M4 rotor to test fit The Alcons seem to gain 1-2mm clearance which all helps

      HR34 GT speedo issue

      By joshuaho96 · Posted

      Probably speedometer itself if the odometer is ticking. If the needle is stuck from a bit of grease or something that can cause it to stay at 0. Or a cracked solder joint in the speedometer can do it too.

      WTB RB25 Gearbox NSW / central west

      By Dylannn · Posted

      Thanks Fella’s   to take this off topic and to elaborate a bit more. I have an rb25/30 going into a r32 GTST.. expected to make around 600-700hp. Would you?   A) R34 GTT box   B) CD00#?  I’ve seen a few posts about the CD swap and sounds fairly involved with making it fit etc but if it’s worth the work then I’ll go that way

      Lower at the hubs. Funny I forgot to mention that part. Do this pull here I turned the camera off too soon but the graph shows a drop at the top and that was because the pipe from the turbo blew off. The tuner said we could’ve made possibly another 15 whp. He also added if I switched to ethanol we could up the boost some more as well. I was comfortable capping it at the most of 20 pounds. Turns out the turbo pipe just needed a new worm clamp. Got home replaced that then did a third gear pull from 3k to 7200 rpm and the power was great to the top. I just got an ecu mounting bracket from IEE that I need to try and get everything to fit well. It’s a PITA to get the harness and ecu fit properly behind that kick plate
