Hey everyone,

I have a bit of a problem which i cant seem to find the answer to.

I bought a damaged r33 s2, Im a panel beater my self so i have fixed the damage on my own. Now i seem to have a problem with the car running with out a problem.

The engine starts but alot of black smoke just keeps coming out from the exhaust and it cuts out as if one of the spark plugs are not working (or a coil problem). I checked all the plugs and coils and they were all fine, then after letting it run for about half an hour to see if the smoke will stop the car just turned off on its own. So I changed the spark plugs and they were burnt out on the tips. When i put new ones i thought to my self i would change the oil and oil filter at the same time. So i did all that but still the same problem.

I dont want to keep the car running for a long period because my guess is that its going to burn the plugs out again.

I asked around and a few people said its my coils, but my own thoughts to that was then why would it be blowing all that black smoke? Then another person said it can be one of my fuel sensors, saying its burning too much fuel thats why my plugs were burning out. So i thought i would ask another mechanic and this bloke said that it could be my air intake sensor.

So i would like to get some help off anyone i can if possible. Thanks.

yeah well its super rich....so i guess thats a good place to start diagnosing from... check the base timing... also check the diagnosis codes from the ecu...

Hey mate,

would you know how to check the base timing or the diagnosis of the ecu, or anywhere in sydney i can get it done? I like to play around with my car my self and feel good about working on it so yeah

im no expert but try resetting the ecu...... its cheap and quick and you'll have a result in a few mins

to reset ecu unhook the negative battery cable and turn the lights on and press the brake for a minute to drain all the power stored in the ecu so it will loose all current memory stored in it.

(dont forget to turn off lights before connecting battery up)

also does the engine shake or sound like a wrx when idle????? if so then it might also be running rich and have a spark problem that may be hard to detect,,,,,

Check the pins in the coil plug - make sure you haven't bent one out of alignment.

yes yes i agree..... it it either the ecu or something to do with the coils im racking my brain here and they most plausable still.....

and since the car is ideling like a wrx and is shakeing, whatever the prob is is making the spark f**k up.....

also check the grey clips that connect to the coils, when i had my sparks changed the idiot mechanic just connected these clips but didnt clip them in place so they just vibrated loose after a few days and made my wrx sound......

should have done it myself the first time but i thought he knew what he was doing..... lol now i know how to do it for next time

Hey guys,

ok i tried the whole reset thing. the check engine light blinked 5 slow and 5 fast. so im guessing that means things are alright. But i also had a thought because of the car accident im missing a pipe for the intercooler? so theres a pipe coming out from the engine but not connecting to the cooler because its missing? im told this can also be a reason why?

lol thats funny :D

To build boost the turbo relies on the piping to transfer it to the plenum, if there is no pipe there you cant have boost and the motor is drawing air through that pipe instead of the air filter so the air flow meter is not in the loop, frankly I dont know how it is running at all.

      "Cheap" bolt on turbo on RB25DET NEO

      The fab work can be as simple as a couple of silicon hoses and clamps to the factory piping.

      Just sounds like either way you need to do some fab work to get everything to fit, so why limit yourself at that point? If the GCG high flow option is zero effort in and out swap though I'd probably do that. It's almost certainly lowest risk, lowest cost, etc. The HKS GTIII-RS option that Kapr mentioned is laughably expensive for what it is, they charge the exact same for two turbos on the RB26 so their margins are off the charts on that thing.

      Intake manifold is not a part of the issue. The turbo bolts to the exhaust manifold. That is easy. But close your eyes and picture the physical situation. That is a T3 flange on the manifold and a T3 flange on the turbo. As long as any new turbo has a T3 flange on the exhaust housing, that exhaust housing will bolt to the exhaust manifold. This places the exhaust housing in the same place as the stock one. But now move your mental attention a little further forward. The location of the compressor housing is set by the length of the turbo's core. The stock turbo had a long core. Let's say that it is..... 100mm long. So that would place the compressor housing 100mm forward of the exhaust housing. But a highflow, might well have a centre core that is shorter. Let's say that it is only 70mm long. Now the compressor housing will be 30mm further back in the engine bay than the stock one. This DOES move the turbo's compressor outlet backwards. It also moves the compressor's inlet backwards. You will very likely have to do some work to both the inlet and outlet piping to make everything connect again. I am not say this to make it out to be a bigger deal than it is. I am just pointing out that "bolt on" is sometimes not quite bolt on. The highflow from GCG that Murray linked above (https://gcg.com.au/turbo-charger-upgrade-skyline-gtst-2iu-xtrgts-s1.html ) uses a core that is the same length as the stock core, and so does not require this extra work. It will look very much like the stock turbo. No-one uses GTR turbos of any flavour (stock, or aftermarket) in a single turbo application on RB20/25. It's not a thing. Yes, people have been putting on GT3076, GTX3076 (and bigger and smaller versions of those) and G30s (of various sizes) onto RB20/25 since forever. But these are not "bolt on". Everything except the 4 bolts to the exhaust manifold change with these. And genuine Garretts are expensive. Non-gen, like Pulsar, etc, are cheaper, variously as good or nearly as good. But still not bolt on. No-one in the right mind would pay for an HKS turbo. Not in this modern day and age. Well, yes, the GCG highflow. You could ask HG what he can do to make the compressor housing sit in the original location. There are surely others doing highflows around the world. And some of the eBay/Temu ones (as reported by Dose) work and don't die. Bit of a lottery though. I would send your turbo to GCG (here in Oz) to be highflowed if you want a trivial no-extra-work option. But seriously, the work required to change inlet and outlet piping is not that hard. That's a boost control problem, not a turbo problem.

      Thank you all for the replys 🙂 I know that intake would be different but that is one pipe at it is not that hard to get(custom one). I meant mainly bolt to the stock manifold and the turbo elbow. I looked and many sites/forums but they are just "old" with some old HKS turbos from GT-R i guess? What about some Garrets?  Or any other turbo? Is there even a turbo which i can just bolt on? 😄 And yeah i know about that new HKS but that is like 2000k USD without taxes/shipping in here   Iam getting a touch up tune but my "problem" is that on the "not" hot day iam getting peaks around 0,9 bar...and when it was around 15 Celsious i saw peak around 1 bar which is just too much for stock turbo. And of course turbo is old and i like to get some new one for a piece of mind 🙂

      I'm working on the assumption that our friend Jasmine here is a Russian (or, possibly Ukrainian) spammer/spambot, based purely on the number of such that I have been having to neuter in the last few weeks. IP address for the OP above was in WA. But that could have been via VPN. Posting at quarter to 4 in the morning is a good sign of being from somewhere in Europe. The last Jasmine that I kicked in the cooch was IP addressed in Ukraine. Even that could have been via VPN, and the bitchbot could have been from Russia, Serbia, China or anywhere. Regardless, was a spambot, so I killed it with fire. The fact that our new friend Jasmine here did not respond in any way to my tart query strongly suggests to me that this OP was just the establishment phase of a user able to be activated for spamming in a week, or 3 or 10.
