Here's a few... and relate to fitment in the engine bay, and compatibility with an existing skyline wiring loom.

The DOHC head sits lower than the single cam head.

The DOHC head is setup to use multi-coils, not a distributor like the SOHC head.

Both require a custom intake manifold, but if you go with a 25DET (you can use a greddy plenum) or 26 head you already have a side mount intake manifold.

Don't get too blown away by a power figure. Anything is possible with enough race fuel and boost. This is not a street car engine, and certainly not one built for a skyline.

Everything else you need to know is here:

Awesome engine. You only have to look at the 7 second SOHC VLs to see what the single cammer RB30 can achieve. Having said that the twin cam conversion still has a lot of benefits - for example more low down torque with the VCT running and a better flowing head when unmodified - of course the the 7 sec SOHC cars are no where near standard and as can be seen in the above video the rocker cover has been cut and shut to allow clearance for the much bigger valvetrain residing within. Because of poor maintenance practices and the location of the radiator on the VL the heads on the SOHCs were prone to cracking so if the head has to be changed why not do it with a twin cam head.

      HyperGear vs Pulsar Turbo RB25DET

      By Eric0 · Posted

      UPDATE: Hi all!  As we are getting towards the end of this thread where I’ll showcase final dyno numbers and graph, I wanted to provide an update. Tao from HyperGear has done an amazing job building the custom divided T3 housing for the G30. Communication was flawless, price was great, and now the housing is estimated to arrive in 7-10 days! Very very pleased. I must add, if someone is looking for an affordable turbo and end up reading this thread, I would recommend HyperGear. Genuine brands are the way to go as their proven reliability, predictable performance, and there’s a plethora of information available for specs, flow, and more. This HyperGear recommendation is based on their excellent communication, dedication, and willingness to listen to their customers. I particularly liked their ability to create custom adaptations tailored to specific needs, which is a HUGE benefit over other brands. And if we consider the HyperGear provided dyno results, it adds reassurance knowing their turbos can compete against genuine brands. Next update will be after the dyno!

      Probolt

      I've previously seen people post up "dress up bolt kits" for RBs but don't remember seeing them specify the full contents. I can only really suggest you grab the verniers and start measuring, and keep in mind the cam cover and timing cover bolts are both quite specific with a wider unthreaded section where the bushes sit, that will make it hard to get aftermarket replacements which tend to be all thread (set screws) or for longer bolts a flat section with a shorter threaded section at the end

      R34 GTT Battery Relocation To Trunk

      By Beanie · Posted

      I believe there was a similar one posted by @duggyphresh. They were re-routing their battery positive cable in the way I am also trying to achieve. Sorry, I’m new to this forum, so was a bit late to the party by a few months and so reignited the old thread, as I wanted to know how they got on with doing it.
