Rb20det Sounding Like A Wrx

[rad100]

well it stopped then started again once car warmed up!

[madevo3]

yeah it would piss ya of wouldnt it. yeah my car played up once like that as well but as soon as i put new spitfires in it it was fine. lucky it didnt pop a piston when it sounded like a wrx not a nice feeling when that happens

[murrayis]

If it idles fine and under load sounds like a wrx could be the plugs fould up, if it does it at ifle leave it idling and unplug the coilpacks 1 by 1 and wait for the ones that make no difference to the sound and their usualy the dead ones.

plugs or coils... as you just put new plugs in i would re-check those and the coil harness connection to each coil... also search for the thread which tells you the different colors for different spark plug problems.

If it doesn't idle, wants to stall and cant rev over 2k then its piping... not 100% on rb20 piping but there are a few that you prolly have to take off to get to plugs which would behave like this if not re-connected properly.. so check that..

I don't know if anyones explained how to check blown coil packs, I CBF reading the whole thread so I will just tell you what to do

Start the car and let it idle

What you do then is disconnect each coil pack one by one, so one at a time from cylinder 1 to 6

Whats your doing is listening for a change in exhaust note/miss fire and no change

So it will go something like this;

Unplug cylinder 1 coil pack - No change in exhaust note means the coilpack is not firing (stuffed) change in exhaust note means its working fine

Unplug cylinder 2 coil pack - No change in exhaust note means the coilpack is not firing (stuffed) change in exhaust note means its working fine

Unplug cylinder 3 coil pack - No change in exhaust note means the coilpack is not firing (stuffed) change in exhaust note means its working fine

Unplug cylinder 4 coil pack - No change in exhaust note means the coilpack is not firing (stuffed) change in exhaust note means its working fine

Unplug cylinder 5 coil pack - No change in exhaust note means the coilpack is not firing (stuffed) change in exhaust note means its working fine

Unplug cylinder 6 coil pack - No change in exhaust note means the coilpack is not firing (stuffed)

change in exhaust note means its working fine

That should determine if its the coilpack not firing or if its something else

To me it sounds like the coilpacks, if its not maybe try changing the plugs - NGK Coppers BCPR6ES I recommend, pre-gapped to 0.8mm so you can put them straight in

yeh i got those coppers in atm!

anyone know how the jjr coilpacks compare to the spitfires??

cheers

[rad100]

anyone?

[Justa32]

dont b a pioneer

[boostin_r33]

Is everyone sure it's coils? Does it sound more like a wrx or a lawn mower? dude it may be your turbo gasket from your manifold side! 500 bucks is a bit much to spend if it's not the right thing thats wrong! thats all! and the jjrs a good but really u pay for what u get splitfire just has that reputation and plus the japaneese use them in the 1000hp supercars! so it's saying something

[joeyjoejoejuniorshabadoo]

check the coils as abu said...

i'd guess at coil/spark issue too

bombtrack had the same prob on his 34

rb minus 1 cyl = rex

Spitfires aren't much more and are well trusted. When I was looking I remember reading a few things about the JJR not fitting too well, sure you can find it using search.
