Sammy Posted March 15, 2007 Share Posted March 15, 2007 Hey there I have a Silvia with an rb20det in it Currently one of my coils - second from the back is overheating/melting and is NOT sparking either. ---It sounds like a WRX----- What would be wrong? We have tried a range of new rb20 coils and checked the spark plug and all are fine any help would be appriciated! cheers sammy Link to comment https://www.sau.com.au/forums/topic/160550-coil-help-my-rb-sounds-like-a-wrx/ Share on other sites More sharing options...
SECURITY Posted March 15, 2007 Share Posted March 15, 2007 could be a dead CAS, although im not sure if its capable of making only 1 not work. it could also be your igniter pack (again, im not sure if rb20's have them). then again, it could be a cracked ring/land. get a compression test.

WazR32GTSt Posted March 15, 2007 Share Posted March 15, 2007 try swapping ignitor packs with another rb20.. takes all of 30sec and a likely culprit this is a common problem on z32's their ignitor packs lose a connection and a cylinder shuts down, or worse all cylinders shut down without spark Link to comment https://www.sau.com.au/forums/topic/160550-coil-help-my-rb-sounds-like-a-wrx/#findComment-2982093 Share on other sites More sharing options...

Sammy Posted March 16, 2007 Author Share Posted March 16, 2007 * she lol we have bought some coils and tried them, however is it possible that red top and silver top coils are different??? cause despite the fact that we bought 'rb20' coils - they are not exactly the same as the ones in the car.

Rancher Posted March 16, 2007 Share Posted March 16, 2007 (edited) Red top and silver top coils are totaly different. Just to give you an example, Red top coils fit onto the CA18DET and vise versa. Silvertop coils only fit the Silvertop. Try getting the right coils, if thats not the problem, then change the igniter (the square thing ontop of the cover) And take that cover off! it traps heat under it and melts coils. A dodgy CAS wont make one coil not fire, if its the CAS it wont start at all.

subzeroR33 Posted March 26, 2007 Share Posted March 26, 2007 As i said mine is running like a wrx as well, and it turned out to be the MSD ignition pack. Are you running one of those by any chance.

R31vhead Posted June 11, 2007 Share Posted June 11, 2007 (edited) Hiya, First of all, redtop coilpacks are different from silvertop ones. Second of all, I think you should double check the wiring into your ECU. Especially since you've done an engine conversion, it's very likely a wiring issue. Look up the wire for cylinder #6 and double check its the right wire for power to that cylinder. I had the EXACT same issue with my car (RB20 into an R31) and it turned out that the coilpack wire had been spliced directly into the temp sender. The result was a constant signal to the coilpack which melted it. Not fun and not cheap. Good luck, let us know how you go.
