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

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 :P

yeh i got those coppers in atm!

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

cheers

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.

      Yeah, plenty of air flow, there is a dedicated path that feeds the air in to the OEM intake tube behind the bumper As for a "tangible effect", maybe, but getting the pod/intake air out of the hot engine bay is worth it psychologically to me, even if it gives no performance difference, so the tangible effect in my Lizard brain saysss yessss  In the end, to me a tangible effect isn't always about performance, sometimes it a sound or a look, or even a...... feeling  Ooga-Chaka Ooga-Ooga Ooga-Chaka Ooga-Ooga Ooga-Chaka Ooga-Ooga Ooga-Chaka Ooga-Ooga

      yeah first and reverse is where you will find clutch release issues (whether hydraulic or mechanical) because the difference in revs required is the highest there; particularly changing down from 2nd to 1st when still moving. To be clearer though, it is possible that the clutch release bearing is the wrong height. This is less likely than a hydraulic issue but it is not unheard of when you are mixing and matching

      Replacing turbo water line - any recommendations or advice?

      By jtha7 · Posted

      Hi all, Restoring r33 series 1 rb25det. All the heater hoses were on their way out, have replaced them and put it all back together. After testing I noticed a small leak from behind the head on the actual metal water line to the turbo when cars warm. I tried running a longer hose over it but it kept leaking...   I am about to take the (stock) manifold off again😔 to change the water line does any one have any lines they recommend? I was looking at Aeroflow Turbo Oil & Water Line Set but not sure what everyone else recommends. Car is completely stock but want to upgrade turbo eventually. it looks like ill have to disconnect a lot just to replace these lines so if there's anything else recommended to do please let me know. Thank you in advance!

      From memory, on the R33 GTSt at least, while everyone says "It's not adjustable", I found when I changed clutches in mine, it just needed a small adjustment on the rod length. But be very wary here, as you could end up trying to push the pushrod in the master too far, or blowing out the slave.   Most likely though, if the master/slave isn't bypassing internally or leaking out, then the throw out is the wrong height compared to the fingers on the clutch, so when it moves to disengage the clutch, it isn't 100% disengaged. You can check part of this out too by jacking the car up, having the engine running, put your foot on the clutch and try to engage 1st gear. If it goes in pretty easy (Compared to the ground) and/or the wheels start turning a fair bit and it takes a bit too much brake pedal to bring them back to a stop, this is likely the issue.  I'm not sure if you can adjust the height of the forks etc in these though, it's been that long since I've touched any RB gearbox.
