Rb20det And 1996 Rb25det Coilpack Differences

[joe blo]

are these 2 typres different? what are the differences if so? i have some rb25det ones that say 1996 on them im thinking of trying in my rb20 that wont rev out good. i changed the sparkplugs on the rb20 and it made a big difference so im thinking it could be the coilpacks. when i was changing the sparkplugs the rb20 coil packs seemed the same but the rb25 ones were in my room so i dunno if they are the same. so are they?

as nismoid said, they are different. series 1 (93/94 models) coils will work.

have you tried taping up your coils? this may help (there is a DIY on the forum somewhere about it).

but you said putting new plugs in worked so why would you then think it is the coils? it was obviously the spark plugs (to a large extent). what plugs did you put in and what gap? if the gap was 1.1mm (usually the plug will end with the number 11 such as BCPR6ES11) then try gapping them down to 0.8mm. if the plug didn't have a number on the end it should be 0.8mm to start with.

it was misfiring really bad when you gave it any throttle at all with the old plugs. now it goes ok and doesnt splutter but wont pull hard when i give it mare than about a quarter throttle.

theres abit of a history with the car. i have another thread on it on here with the problems if you have anything to contribute to it.

its a rb20det in a vl and when the guy did the modplate last year in august i think he said he remembered about it having isuues with the coilpacks. he remembered it coz i had to go back to him after i bought the car coz a letter on the modplate was wrong and he asked if i sorted the coilpack issues so i dont know if its ever ran properly since the motors been in the car and its been passed on two or three times since he saw the car so im thinking it might still be the same problem.

the guy i got it off said his mechanic said it was fuel pump or fuel regulator. the guy before that guy said he replaced the intank fuel pump and it was still the same. so i want to fix it cheap hopefully sometime.

if anyone in brisbane can loan me some coilpacks il get them off you for abit if your a cool dude so let me know. or one of the igniter boxes il try also.

i used the plugs without the 11 on the end im pretty sure
