I know it's probably not going to cause any major engine issues. I just had a more generic concern that it's technically not running right (I guess this means the rpm is not sitting where it technically should be) Though the other thing is, it's that my steering wheel is shaking at 1,100 rpm at idle until it gets warm (seemed to happen after I tightened my alternator belt, will be testing the alternator soon).
-
Ok will keep in mind. Appreciate your help!
-
I suspect that to.
-
That sounds pretty easy actually haha. But is there a reason why the tuner didn't do this? It's not like I've got a cammed 500kw rb25 neo. Also the tps plug is different on the rb25det neo and the r33 for example, I guess I'd plug out the loom which is this end? There's also 2 connectors.
-
Ah right that makes sense.
-
Apexi, though I'm not comfortable with setting the idle, knowing me I'll f**k it up lol.
-
Yep. Saw that on the image above but, wonder if it makes more sense to clean out the iacv because let's say in theory mine is dirty and if I clean it the rpm will drop. If I first go to my tuner to drop the rpm and then go to clean my iacv won't it drop further or is the rpm a fixed number?
-
Oh ok, so looks I should be resolving this? I was thinking of cleaning the iacv, and maf for a start and checking for any loose hoses. Already did a boost leak/smoke test and was all in the clear. I'm suprised the tuner didn't say anything.
-
Is the 650rpm idle on the rb25det neo for stock cars only? I've never had my car before and after tuning it to idle at 650rpm when cold. Always idle's cold around 1100rpm, and then drops to about 900-950rpm. I've heard the r33 gtst's idle there.
-
Ah yep, will do. Cheers!

I went to Repco to get them to test the battery using their tester (not a volt meter), alternator shows 14.3v when running, and when the car was off after the it was on full load I think it was 12.6v but the guy said it was all good. Terminals are all clean, no corrosion. Though I coulda sworn when I tightened up my alternator belt the car idles a bit higher and the steering wheel shakes a bit until it's warmed up. I wanted to confirm for the earth cable/s, are you referring to the 2 wires that are bolted onto the frame rail under the battery? I might be overthinking this a bit.
-
nvm this comment
-
I'm almost at a point where I feel like changing the alternator. Need to check the stuff you mentioned first though.
-
Funny thing is when i flexed the belt it seemed like it had the same tension as before. Like I didn't tighten anything lol. Will start the car again tommorow and see what happens
-
Will do. Suprised if it's not the starter motor considering it's 30 years old. Will get a volt meter though. Battery is close to new. Cheers for your help, always appreciated.
-
I just checked my belt, it wasn't super loose but I could bend it past 90 degrees a small amount so I tightened it up and for the first time ever my car didn't crank first time, had to crank it again lol. Don't know if that was because I tightened the belt or if it's my starter motor going out (been having slow starts for some time). Coulda also been when I was recording I didn't crank the key properly and it didn't save the recording lol. Is that a thing if you overtighten a belt it struggles to start?
-
Which grit sand paper did you use on the pulley btw? Thought I'd ask so I don't scratch it up too much
-
Did that last time and it was squealing like mad lol. But my belt was loose at the time. I'll check the tension tomorrow, think I checked it a couple of months ago and was fine.
-
Gosh these Rb pulleys/alternator or whatever is causing the problem is absolute rubbish lol. Haven't even done that many km on it.
-
I've seen these as well https://www.ebay.com.au/itm/395822887806?chn=ps&_ul=AU&mkevt=1&mkcid=28&google_free_listing_action=view_item&srsltid=AfmBOooak9PFJJwwNDusr8TrZ5lsminTjComhJr-Z4dJ52Tt35T1hBPl0wk&gQT=1 but always seemed a bit dodgy lol
-
Does anyone find that they have to tighten their alternator belt once in a while? Mine started squealing again.

Ceramic turbine damage to engine - what did yours do?
silviaz replied to Erelyes's topic in Engines & Forced Induction
Ah right. I got a new o2 sensor because the last owner disabled it (probably because it was dead and didn't want to buy a new one), here goes potentially for a new o2 sensor again lol. -

silviaz replied to Erelyes's topic in Engines & Forced Induction
From what I understand, it's a ceramic turbine and a plastic compressor (not sure how it doesn't melt then lol) I heard the series 2 r34 gtt has a metal turbine but I doubt that. @GTSBoy When you blew your standard neo turbo it didn't cause damage from memory just the turbine ended up in the cat? -

silviaz replied to Erelyes's topic in Engines & Forced Induction
Is that just in the context of a gtr and not a gtt because twin turbo vs single turbo? -
Is the A/C compressor supposed to keep kicking in and the revs go up every so often as a result? (for a r34 gtt) Mine turns on roughly every 15-20 seconds if I remember correctly. I know on my other car it doesn't seem to do that but different car I guess. I've had my car re-gassed and it still blows ice cold air after well over a year but have always had this happening.
