Anyone know my an Rb25 would be putting out on idle?



My money is on one of these :- coils, plugs or leads. Try taking each of the plugs out and inspect them they should all look same on ends. If u want take a pic of each 1 and send to me if your unsure what your looking at.

Your engine has leads?

Also plugs only show last condition before removal.

Ie- if the engine was belted then shutoff at full noise for inspection, vs belted then cruised to a convenient place for inspection will look very different. Most ppl look at them after the car idled for a period of time therefore true readings get masked


So... What's the question?


His car has a very rough idle atm, at 1st I thought it was his cold start but only has a standard ecu, so then was thinking vac leak? He sent me a video of how it sounds and its really rough so my thoughts were what I mentiond above and yeah did mean coil packs.

    • When you pulled it off, there is no signs of blown head gasket? Is it possible you have some other issues going on? Possible cracked blocked? Or do you think it's straight up lifting the head? Did you check what the head was torqued to before pulling it down (To see if possibly they're stretching, or starting to break threads out etc)?
    • Seems like a decent result for a modded JZX110. They are bulky in comparison to the 100 and 90 models (which I'd prefer myself) but they are getting very few and far between here in JP these days. Thanks for the detailed review and the import process into the UK. I also have a car which I'm hoping to export from Japan at some stage so it's good to know if someone from the UK was interested in it. By the way the corrosion underneath is par for the course for cars which were located in/near the mountains or along the Japan sea coastline. They get huge amounts of snow every winter and the sodium chloride is used on the roads. Many cars have some kind of rubber like treatment underneath but they tend to limit it to the wheel arches underbody and fuel tank. Suspension arms and sub-frames will have similar corrosion to your JZX110 which is a common sight. See it all the time and car dealers here generally don't even mention it unless asked.
    • If the sound goes away when you clutch in, the 1.5/2 way diffs are just shit, and you are a normal person. The diff is likely "fine" but driving at anything under 30kmh is a violent horrible experience. It would be exaggerated with solid diff bushings and subframe bushings if you have those.
