Hi all,

 

so don’t get to get under my gtr much in Hong Kong. Used to get under my cars all the time in the states. 
 

anyway my garage took out my hks silent hi low cat and was wondering does it just bolt back into the system with new gaskets? I’m guessing yes. 
 

Photo attached. Thanks

Yes, just throw some gaskets at it and put it back in. As long as everything is actually designed to bolt up together it will all go back together. My CA compliant exhaust for example can only fit with the specific catback I gave them.

Thanks everyone … will give it a go. Hope the added back pressure doesn’t screw up my weak rich idle issue I have… would be great if it helped it😃

Running rich in conditions where it shouldn't probably won't do great things for catalytic converter lifespan. I would fix that sooner than later.

Yeah very valid point. I am waiting for one of the other tuners to come back from vacation so he can help me a bit when the cat is installed again. In the meantime I am going to finish up my polishing and ceramic coating that I have started myself. 

 

N45 Dr Beasley product is highly recommended for a paint primer / polisher. Using this EXO Gtechniq also for the ceramic but next time might use the light serum before hand also. Looks great.

Just an update  ... Put the cat back on no issues with the car running wise ... maybe alittle longer to spoil up the turbo. Still running rich but waiting for my tuner to come back into town to retify the situation. WOT runs fine with the cat.

    • 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.
