Cool. Well it seems like the logical way to go to try and maximise power while trying to keep the boost to a slightly sensible level. Otherwise I will have to run the car on straight methanol to take advantage of the super high boost and not have detonation issues! lol.

You should move here now....its starting to warm up quite rapidly. QLD likes to skip spring and go straight to summer!

hahah So did Canberra...went from 5 deg C to 28 overnight

Methanol would be fun then add a splash of Nitro Methane....you know about 15% and have some fun with 60psi lol

I am drooling at that thought right now......You know my uncle has a couple of drums of methanol in his shed.....the 99.9% pure elf racing indy grade stuff!

Just need to fab up a 200litre tank so I can make it to the shops and back!

Quickly worked out the numbers. 60psi would be piss easy to achieve, 0.7bar from the charger and 2 bar from the turbo. Boom 4.1bar = 60.27psi

there was a Hyundai excel drag car that used to run 86psi and rev to something like 10k

they would usually last a few races and then crack the bores and they would just replace it with another stock block, pretty funny.

He got a little carried away with the rb30 for the race car and forgot to put the grubscrew oil restrictors in! Only remembered when he was fitting the turbo to the exhaust manifold. Had to take head and surrounding shit off to fit them!

The two 6mm holes would have drowned the head in oil for sure lol.

I am hoping to go, but only if I get the car finished in time and sorted. If not then I wont bother going.

Turbo is assembled and bolted on loosely. Everything appears good so far. Need to get oil and water lines sorted now!

lol im sure you wont die before I get it done. Finished mounting the new intercooler and nearly finished off the new charger outlet piping which got destroyed when I removed it off the charger...that threebond sure sticks lol.

Weve been working on the race car for the last few weeks so there hasnt been much time to get my own shit done :(

Hopefully tomorrow if bathurst doesnt catch too much of my attention I will be working on the exhaust!!!

      R34 GTR Speedo Drive , sensor type ?

      By Butters · Posted

      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 ?

      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

      Can you mount the ATTESA pump in other locations?

      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.
