What Coil Pack

[66yostagea]

Need to get some for the N/A 25G. What is the difference,if any, between RB20T, RB25DET and RB25DE.

[0t1]

Nothing really, 20's won't plug up different connector, 25DE/T very much the same, I use the pink or red aftermarket ones on our 25's, as long as they are new is the key,

If you look up the splitfire website it will tell you which coils fit.

My preference

1. New OEM if you can get them at a good price

2. Splitfire

3. Yellowjackets

None of the rest.

This one I think:

Actually at $410 plus postage I think the Yellowjackets would be the better buy:

I've just done coils, went with the yellow jackets. They suited my busker and have had good reviews, and I could not be happier!! They are amazing. Didn't think it would be such a noticeable difference, but everything just feels better!

What is different with them? More response with the stronger spark? If they are stronger? Any difference from Standard coil packs when they were running on all cylinders?

[KiwiRS4T]

Very hard to get any objective results.

I like the OEM (brand new) because they have been proven to last 10 - 15 years!

Splitfires have built up a reasonable record by now.

The Yellow jackets have stood up well on the dyno and on the track.

Some of the others have failed relatively early in life.

The test is not whether one makes more power than another - they are just coils after all - but how reliable they are.

Reckon its worth changing my plugs or is it pointless unless I change the coils as well?? Just running OEM atm

Get some coppers BCPR6ES gapped to 0.8mm

[66yostagea]

Talking about plugs. I bought a set to suit "RB25DET" I never really looked at them except to gap to 0.8mm. Stag is not too happy with plugs, now I see they are "7" not "6". Whats the difference?

Any point replacing OEM with 11's? Or go for 8s for better high power performance/econ?

[KiwiRS4T]

They are the same plug but -11 are pregapped. You may as well gap them to 0.8mm as the bigger gap won't gain you anything.

Thanks for all the input. My Nismo99 son is getting me a set of coil packs. Will fit them soon and let you all know how it goes.

Heat range, Were they for your 25DET or for your DE? 6 would be better for relatively stock DET and 5 for DE

Thats what I thought. Thanks Bob.
