Can S2 R33 Coils Handle Over 13psi?

[Lithium]

Yea it happened really bad one night when the air was still pretty hot. I found a few FAQ's on how to insulate the coils, So i might give that a go and replace the spark plugs

How did you go with this?

Yeah you can fix the coils when they die, but often is easier to buy new ones

That probably depends on how baller you are I think, either way you have to pull everything apart to get at the coils - one way you have to remove all the coils from the bracket and put the new ones in (not to mention spending >NZ$1000 on the Splitfires) or you spent NZ$15 on some silicone and just give it a dowsing on the base of the coils while still in brackets

Is Silicone or araldite better for this application?

Lithium, could you see any crack or tell tale signs of arcing. Mine look ok...

I used silicone. I actually had ~19 old S2 coils lying around and filtered through all of them to find the ones that seemed to be visible in the best condition, no cracks - the epoxy and the boots etc all looked in pretty good condition. Took the car for a test thrash and it had a misfire, so got back and tidied/stretched the springs a bit and did the silicone thing - put them back in and took it for another drive and it was better than the car had been in ages!

The guys who had been observing were both major critics of trying it and were voting I just keep trying different coils, and thought I was taking the piss when I said it fixed the problem - had to actually experience it themselves!

I had this problem with the engine missing under load at higher RPM after increasing the boost on my R33 to 12psi. Everything pointed to coil packs and everyone said to replace them but I thought I'd try a $24 set of plugs instead (gapped to 0.8 instead of the factory 1.2) and that fixed the problem. Don't spend $600AUS on coil packs unless you are very sure you need them

gaping the plugs down does not fix the issue it simply masks it the issue will come back (smaller plug gap = easier spark). your coils should easily be able to run 1.1mm plug gaps at any power level the stock turbo is capable of producing.

im a %100 tight arse so what i did with the loom was make a new one up myself and just solder the wires straight to the coils.

then i just tape the coils up, the only problem i have with the tape is i find it needs to be done again every 15000ks or so, i need to silicone them when i pull them out next time.
