How do I set ignition timing on RB30 VL?
The ignition timing is adjusted with the slotted screw/pot in between the two extremes. Start with the screw in the middle position, adjust the ignition timing to 15 degrees by moving the distributor body, adjust the idle rpm (back) to 700+/-50 rpm by moving the slotted screw/pot – which moves the ignition timing via the ECU.
What can I do with the RB30 engine?
That’s more than you might imagine so do your research carefully or risk biting off more that you can chew. Significant gains on the RB30 can be made from cam upgrades. Altering the cam profile alters the intake and exhaust durations on the engine and can dramatically change the engines power and power output.
Can a R33 RB25DE / Thas variable cam timing be interchangeable?
N/A valve springs have less tension which may cause issues when running big boost. Cams and springs are interchangeable with RB20DET items. The R33 RB25DE/Thas variable cam timing (VCT/NVCS); this requires welding of the heads VCT oil feed. The head still requires oil to its VCT, you will have to tap in to the oil galley and run an oil feed to it.
What should compression height be on RB30DE engine?
CP make a nice RB30 Flat top piston suitable, it runs a 1.280” compression height, deck the block 0.020” to achieve a zero deck clearance, run a 0.040” head gasket all to achieve a nice 8.2-8.3:1 comp ratio with a nice tight quench that aids low/mid range power and improves fuel economy.

What’s the top speed of a Nissan RB30DET?
To compensate, the RB30DET produces more torque at lower revs due to its longer stroke. However they have been known to reach engine speeds up to 11,000 rpm with a lot of balancing and blueprinting.
