![]() currently does not make a bolt in disc for those, although we could add this if demand is there. The RB motors, VG30DE / VG30DETT, and CA18DET use a different cam angle sensor that is difficult to take apart. Treat these values as a starting point, not the definitive, final numbers. Because the CAS or distributor has some built in adjustment, it’s likely that many installs may need as much as 20 degrees of adjustment, so you will need to check your timing with a timing light. If you find one of the engines needs trigger angles that are off significantly, please contact us and we’ll add the information to this article. Note that some motors may use different angles from the ones shown in this writeup, as we haven’t been able to test the trigger wheels in-house on all possible applications. Our trigger discs are meant to be installed in the orientation shown below if they are installed upside down, you’ll need to change the trigger angles and some other settings. Just unscrew this, remove the disc and put ours in its place, and bolt it back together. There’s a single Philips head screw that holds the trigger disc and its mounting plate in place. You just need to remove the distributor cap and rotor, or the CAS cover. These motors use a fairly easily replaced trigger wheel. To get around this limitation, we’ve come up with a set of bolt in trigger wheels for many Nissan applications, including the L28ET, VG30E / VG30ET, KA24E / KA24DE, and SR20DE / SR20DET. Current MS3 firmware supports the SR20DET, RB series, and VG30DE/DETT trigger wheels, but MS1 and MS2 are only able to use this type of trigger wheel for a basic distributor. Many Nissans used a distributor or CAS with a set of four or six inner slits and 360 outer slits. qt.)ģ,000 rpm (353-451 kPA, 3.6-4.Converting your Nissan distributor to a more MegaSquirt friendly design lbĬompression differential limit between cylinders.Step 5: Turn all bolts 65-70° or to 123 Nm 12.5 kg.Head tightening procedure and torque specs: The VG30DE is equipped with hydraulic valve lifters. The intake valve diameter is 34.0 mm (1.34 in), the exhaust valve diameter is 29.5 mm (1.16 in), the duration is 248° for both side. The engine is equipped with VTC (Variable Timing Control) system for intake cams. The camshafts are driven by a single timing belt. The has double over-head camshaft for each head and 4 valves per cylinder.

The connecting rod center distance is 154.10 mm (6.0669 in). The Nissan VG30DE motor has two compression and one oil control rings. The cylinder bore is 87.0 mm (3.43 in), piston stroke is 83.0 mm (3.27 in) and compression ratio rating is 9.0:1-11.0:1. The VG30DE has a cast-iron block with a four-bearings crankshaft supported system. General information Engine SpecificationsĢ45 Nm (25.0 kg The breakdown of the engine code is as follows: Cylinder bore and piston stroke is 87.0 mm (3.43 in) and 83.0 mm (3.27 in), respectively.
