Don't get bosch.. they are not good spark plugs for the RB26.

i have NGK BCPR7ES which come standard set to 0.8. leave them at that and the car will run great.

    • Shove more foam in it as a minimum if you possibly can. Or steel wool (not the stuff with soap on it!) Baffles / getting the oil out of the air is huge, and should be done at both the cam cover, and the catch can.   I'm about to do a power steering reservoir, and even that needs some thought to make sure air is separated from the oil, to stop evil Cavitation. I'll probably look at doing my own catchcan later on too.
    • I was once told, who it was I'm to old to remember, that the length of the OEM wheels brace supplied with a vehicle is designed long enough for a average person to apply enough torque to do up, and undo the wheel nuts to the specified torque  What a average person is is anyone's guess though, i.e. average fat bastard, average knuckle head, average perfect sized human......like me Unless of course, a tyre shop has ugga dugga'd them up to "torque to yeild/strip" specs, used cross threading as natures lock tight, or a big breaker bar was used to tighten them up to get some nice stretch in the poor old wheel studs Me, I torque wheel nuts to 1 elbow joint click, lower torque settings are based of wrist clicks, higher torque settings are based of shoulder clunks, or total dislocation for anything that requires all of the torques 
    • I think the catch can design is pretty flawed. Evident in the fact that the V2 one moved to a larger top mounted filter which alone would have helped with overflow and reduce restrictions compared with the side filter. I also imagine there was a major improvement to the baffling design. It is worth mentioning that this catch can with the RB20 was never as much of an issue and the high kms RB25 is likely a part of the problem. I have gotten quotes for both a new "Vibrant Gen 3" catch can and to modify this existing ones but that may have to wait until after the track day. I hope the sump/head breathers/drains and cam splash plates will be enough
    • Yep, both. The ratio is 1.8 instead of OEM being 1.7. The rocker bodies are modified with a larger bolt hole and re-threaded with 10mm holes instead of the 8mm YT has stock. Finding out they don't actually fit the stock castings cause a lot of un-impressment by the person in the USA who tapped the new holes for the 'upgraded' YT product. He was very unhappy with them given their previous design did not require 'clearancing'
    • That too, but I think this is why she's put the work into the cam cover baffles. I mean, a catch can should only need to be a catch can, not an oil air separator also. Not to say that putting the effort into having it do a better job of oil-air sep is a waste of time, but doing the sep earlier is always going to make life better. And that should happen now anyway.
