Hey guys,

A friend of mine has an R33 S2 GTST. It's reasonably modded - Intercooler, clutch, Mines ECU and I believe a T28 turbo. The problem is, whenever you drive it - no matter if you drive it slowly or if you give it a bit - it feels like it's bogging down. It feels like the clutch is slipping - the revs just climb and you dont go anywhere. If you put your foot on the clutch and rev it a bit it goes away for a small while and then returns. Apparently this started happening when the orginal turbo shattered and the T28 was installed.

Any ideas?

We put the stock ECU back in last night and the problem was still there.

Thanks.

Yer, but does clutch slippage act like that?? :S

I should also point out that the car has been doing this for about 8-9 months now (I dont know how the driver has put up with it). And the problem hasnt gotten better or worse. Wouldnt a slipping clutch get worse?? - Occasionally the problem goes away for a few hours (maybe once every two weeks?) .

if its always been like that then it might not be clutch

generally the clutch slip will get worse and worse, and then just completely fail. it could be that its just stupidly rich and when you put the stock ecu on youve hit the stock rich and retard protection. turn the boost way down to like 7psi and see if you have the same problem.

if you dont, get a real ecu (read: powerfc)

    • Working through possible solutions of converting my mechanical speedo.    Anyone know what type of speedo sensor the factory r34 gtr getrag has ? what the output is ? I assume its not a VSS and more a voltage like earlier speedo sensors ? Can an ECU read it ?  
    • roof rail delete used to be a thing, they were made locally for a while too
    • I can get more photos of it here soon and I plan to make a thread detailing the process. I received the car this way and it sorely needs refinishing. That is probably the most appealing photo of it. Up close it is fading, cracked, and needs to be re-glued. Depending on their condition I'm on the fence between refinishing or making a new set.  Another angle hiding the pimples and razor pumps  
    • According to this thread the RS4V with build plate RC40 comes with the R200 diff @ 4.083 ratio as well (mine has said RC40 denotation). We may need to check if the axle stubs are the same pattern as well. The auto subframes have longer axles. However I think yours being a later Series 2 as well, we should have the same bolt pattern for the diff stubs. Unless your upgraded rear also has upgraded axles. Either way, I would not be opposed to pulling the covers to check so I can inspect that  fancy rear core  Also I don't have HICAS. I don't believe that should change things but I hope the people here with heaps more experience than me can correct me if I'm wrong   Let me know if you want to attempt to make this work and I can get some pictures of mine from under the car. 
    • It's not that straightforward. For example I have had this code because my ignitor/power transistor wires were unplugged. It knows something is wrong but has no idea what it means. If you want to actually diagnose this I recommend following the service manual flowchart for code 21. Ohm out the harness, coilpacks, inspect the ECU, etc. And again, it's entirely possible for there to be no problem at all but if you're running a different coilpack it'll trigger the code because it doesn't like what it sees.
