Get a dump that fits properly,

I got a cheap one that required heaps of modifying to fit and it ended up costing as much as a good one,

And i spent heaps of time on it.

Make sure if you get a split dump, the small pipe clears everything, O2 sensor in the right spot.

the clearance under the floor, mine was too short.

What a nightmare.

explain in further detail? Please..

It's pretty obvious. RB20 is short 500cc of capacity compared to the 25, so it is harder to make the power straight up (more boost obviously needed). Then, on top of that, they run out of injector capacity and the AFM goes to 5v well below 200 rwkW.

Yeah,I'm with it.

obviously needing injectors and z32.

I never thought they make ~200 with just a turbo slapped on.

My 2 cents

My 32 with rb25 turbo 14 psi that drops to 12psi after 6000rpm, blitz fmic adj cam gears nistune Walbro pump 3" split dump 3"cat 3.5" cat back exhaust manual made 160 rwkw

Mind u I made the same power with half the boost (14psi stock turbo 7 psi rb25) which was 140rwkw

stock 25 turbo simply does not flow more than 200rwkw on a 25 (with a realistic dyno operator) and for an engine that is 25% smaller i'd say there is next to no chance

    • 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.
