Incase anyones interested...heres some pics on what needs to be done to an RB26 headto fit large lift cams.....some people diegrind them in the car...but this is how is should be done....
Is that you're engine you're workin on? If so o0o0o0o... And you need a shave :D

oh and thanks compnerd...i am shimming it up tommow....no bucket change providing i can get the shims in the right size...they look like the old kawasaki motorbike shims so i should have a large range available between these and the nissan ones

think you need to break it down to simpler terms than that lol...

did you end up fitting all those other parts you had before all this or you gonna do it all in one shot?

Hi ylwgtr2, I am confused. If the standard GTR camshaft is what, 8.2 mm lift and you are fitting cams to suite a pair of 2530's, so you would not be using much more than say 10 mm lift. It looks like you removed a lot more than 1.8 mm. Plus camshaft lobes are around 20 mm across, how do you get a 20 mm flat using a tapered and round drill bit?

Or am looking at this all wrong?

spot on sydneykid...its 10mm lift...but i have removed a bit more than i needed...better to be safe than sorry....i didnt want to take the head out of the mill to find that i need to do it all again! ...the bit i used was the same size as the factory used on the original machining

    • I wasn’t able to replicate the sound anymore. It was a one time sound so maybe it was just coincidence but it was like small pebbles being dropped in a coke can.   should I try cleaning the MAF? It could be it’s functioning but dirty? I don’t know.
    • Update 4: Hi all. The car drives again! Haven't driven for long, only to store it in the garage again, but the test drive was successful. The coolant and oil leaks seem to be fixed for now. Temps on the engine were also very good, while moving I never even saw 80C water during the approx. 30 minute drive. Ate up all the coolant in the reservoir though so will have to fill that even more when I go to the car next time. One thing that pisses me off is that the RPM gauge is still f**ked, I even resoldered the board twice and used copper paste on the silly screws that are used as connections. Next time I take it out I'll take apart the board and fit new components, I'll see if I can get a replacement IC for it.  I have an appointment set for 22nd of September for the engine tune to 370hp. Alignment also still needs to be done. My hope is that I can get all the legal stuff over with by the end of this season. Anyone of you have advice regarding intercoolers? Currently there is an APEXI core fitted, one of those weird hybrid ones, 600x270x76. I don't think it's bad but it's not new and now I still have the chance to change it now to legally include it in the paperwork. Only issue is that the only options that would arrive in time are a HKS Type R intercooler or generic Ebay spec intercoolers comparable to a JustJap one. Ideally I'd order a Plazmaman but it takes over a month to receive which would mean making the car legal has to wait until next season. Would love to hear some input on this. Same story for my injectors, the previous owner was a nunce and put ID 1050x on the engine. They work but are obviously not ideal at "normal" power levels. But I don't see a reason to change them unless the tuner says it's necessary. I read online before buying a different exhaust that the top secret style rear diffusers won't fit due to the size of the rear resonators. My buddy and I made it work by slightly "adjusting the shape" of the mounting bracket and making some spacers out of 3d print for the mounting bolts. Fits like a charm. Just putting this here in case someone has this problem. Even the hefty HKS Silent Hi Power rear can fits without hitting anything.
    • Well they got my money but they are not getting my gearbox ! 
    • It's needed for rolling idle up, and I think it is a decider on VCT also.
    • I mean, not really. Link ECU's can absolutely still have errors from the ECU thinking it's getting a sensor it's not expecting. I would imagine the speed at the ECU level in Nistune does absolutely nothing anyway? I assume the ECU does not do any fancy TC stuff with regards to front+rear wheel speed or anything of that like anyway. Someone who uses Nistune may be more fluent in it.
