Hey guys this isn’t a fab question but I couldn’t find the precise place to put this. 
how much money and time would it take to get an engine converted with hemi heads and pistons/is it even possible. I’m looking at doing this for an RB26 build I’m putting together

also if anyone knows of somewhere in SA that does this could you leave a link or a name for the place.

thanks I’m advance

What do you mean "converted with hemi heads"?

Let's make a few points.

  • I'll presume you do not mean "hemi" as in "Hemi"....ie Chrysler heads. That's what a lot of people would mean when they say "hemi heads".
  • I know and totally understand that the concept of hemi heads is much wider than that. Example such as ALFA twin cams going back to the 50s spring to mind, amongst hundreds of others.
  • Are you aware that there's not really any such thing as a 4 valve hemi combustion chamber? Have you ever seen one? There isn't room to fit 4 valves in. That is is why 4 valve heads are all pentroof design (or some variation thereof).
  • 4 valves provide more valve/port area than 2 valve heads do, which is why they exist.
  • Going backwards from 4 valve pentroof, to hemi 2 valve seems.....backwards.

      R34 Gtt Wheel Offset Advice

      By GTSBoy · Posted

      What can't be done with a little bit of decking board or similar timber bolted to a hub flange via 2 wheel nuts is not worth talking about.

      R34 GTT idle problem

      By silviaz · Posted

      I noticed something. On the tps sensor and the sensor behind the adjustment screw is adjusted towards the far left. Are these screws supposed to be centered? (this sensor was in the same position before the tune as well)  Also attached a photo of where my car usually idles at when warm (sometimes a tiny bit above that). I think I might have screwed up the calculation and it might have better than I thought lol at 750rpm still not 650rpm though.

      So for both general interest of engine health, and to rule out any coolant/oil issues, I organised an oil analysis done on the 125,000klm oil Results below, all good, just a bit of fuel dilution which I'm not too worried about

      This is actually a really good way of measuring what wheels fit. If only there was a similar measurement between hub face and suspension :p That said, it's probably pretty simple to actually measure it all with the wheel off the car for the rear. The front is a bit more complex but..

      Being the top Google search result for R34 wheel-related inquiries, lemme throw down my experience. I calculated that 100mm from hub face to wheel face is about the perfect fitment for my ENR34 sedan.  I've been running 18x8.5s, ET35, with a 1" spacer. So, 8.5in to mm = 216mm. 216/2 = 108mm. 108-35 = 73mm. 73+ 25 (1" to mm) = 98mm.  If you wanna get close to this on dif widths, here are the offsets you'll want: 9" - ET around 15mm 9.5" - ET around 20mm 10" - you're crazy, but ET around 30mm All these should fit perfectly on a non-widebody, non-GTR Skyline. Note that it's probably the absolute max, and you're probably better off running a couple degrees of camber in this config, but it looks great, super flush.
