Skyline R33gtst

[chrisz]

Hi every body,i am new to this forum and from what i read over the past weeks i am sure some one will be able to assist me.

I am on here on behalf of my son and i am hoping you might be able to help me. He bought a skyline r33 with the rb 25det series 2 engine about 18 months ago, every thing was going fine till about 6months ago when he started to get a missfire. We found that the original coil packs were shorting out. I bought a new set of super spark coil packs and had the mechanic replace them. the car ran fine for a week when all of a sudden it started to missfire again and i thought it couldn't possibly be a ciol pack problem so this time i took to a high performace tune up specialist specilizing in skylines. After putting on the dyno and checking the entire system he found one of the new coil packs was not firing and we replaced it with a second hand nissan one and again every thing was ok. The faulty pack was replaced under warranty and we took out the second hand coil pack and replaced it with the new super spark pack. Two monthes down the road and would you believe it the same problem again, this time we took to a high performance specilist in melbourne who found 2 coil packs not firing. Had to pay for a genuine nissan coil pack just to get the car on the road, the car was once again running fine and after complaining to super spark supliers had the whole set replaced under warranty. I have now replaced all 6 coil packs again and 1 month later one of them has already failed

my son's car is stock standard apart from the front mount intercooler it has been checked by 3 different specialists and they have found no other problems, the coil pack loom is fine and has checked and it runs at standard boost. The thing is the problem has deffenetly been the coil packs but i realy can't see how all these coil packs can be faulty and fail in such a short time. Is there anything that could cause the coil packs to fail? His ECU is standard as far as we know and the mechanics do not seem to think it has been tampered with. Please help if you can. I can only tell you what the mechanics told me so i don't know how compitent they are as i think that there has to be something causing the coils to die, so fer it has been cylinders 1-2 and 6. I am thinking of taking to a place called "Just Jap Auto Imports". Does anyone know of a good place to take the car? I have been told that there could be an electrical problem can some one please shed some light on the subject ? I am a pensioner and can't afford paying when they don't find the fault and just tell me that the coils are faulty. I don't mind paying if they find the problem and not take the easy way out and surely we can't be so unlucky to cop all these faulty coils. I now this is a long thred for a new commer and i am sorry to be a bother but please can some one help. Thanks Paul

hi and welcome.

as for the coil issue, there could be a fault somewhere in the ecu (such as the ignition driver) that is causing the coils to fry.

Hi Paul,

Just Jap ar great. Coilpacks are notorius on the 25's. Shell out (there should be a group buy on here) and get a set of splitfires. They do have the habit of all failing around the same time.

Second hand is just not worth spending money on.

Cheers,

Ken

Hi every one, Thanks for your quick replies and feedback i just want to say that i will take every suggestion very seriously and hopfully find the problem. I made a mistake with name in my previous message about where i am thinking of taking the car, the proper name is "Advanced Jap Auto Imports" in tottenham vic. so please let me know what you think. As for the coil packs they were all brand new and they are the Supa Spark brand. Thanks Paul

Thanks for you input the coil packs were brand new and the brand were Supa Spark, if i changed over to splitfires do you think they would overcome the problem? I agree that second hand would be a wast of time. Tahnks Paul
