Late VG30DE(TT) Adjustable VTC Pulleys

Compare to Early VG30DE(TT)(Z32 '90-'93)

Click here to identify your VTC type

Beginning with the 1994 NA model Nissan changed their VG30DE VTC pulleys to a multi-piece unit with a separate outer drive pulley; the TT followed suit in 1995. The internal mechanisms are the same as the early model VTC except for the substitution of using teflon sealing rings. Most importantly, the piston return spring is exactly the same as that which was used in the Early model VTC, and this spring is the primary part which allows VTC noise to occur.

At first glance, a stock Late VTC appears adjustable, similar to aftermarket race pulleys, but the bolts used to attach the pulley are located on the back making them completely inaccessible once the VTCs are installed on the cams. The bolt-on pulley with adjustment slots are more of a production aid which allowed the assembly worker to align the timing marks faster during manufacture. However in doing so, the bolts are typically not centered in the slots and do not allow an equal amount of adjustment from either side of zero. When BDE rebuilds late model VTCs, we set the bolts directly on center with the adjustment slot, allowing a full ±10° (crankshaft) of adjustment from either side of zero. Also, BDE relocates the adjuster bolts to the front of the sprockets making them truly adjustable when installed.

    PN: BDE-1100E, Adjustable VTC for Early cams (or Late cams using JWT adapter), Price - $660.00 per pair

    PN: BDE-1100L, Adjustable VTC for Late cams, Price - $660.00 per pair

    +$500.00 Core Charge for Late VTC per pair

    Cores must be the same version as purchased, under no circumstances will early model VTCs be accepted as cores towards the purchase of late model VTCs.

Optional 3rd Element Timing Indicator

    Camshaft degreeing takes into account machining variations throughout the entire engine and synchronizes each camshaft's timing precisely to the crankshaft. In the past, after degreeing with a traditional two element timing system, the end number on the adjustable pulley's timing scale would have no relevance to the now "degreed" camshaft timing and this could lead to a potential for confusion while tuning. Multiple camshafts, all with different final settings, tend to compound the issue even further. The BDE 3rd element allows camshaft timing to now make sense after degreeing so you can make tuning changes on the dyno and always know where your original degreed zero point was.

    Includes two 3rd Element timing indicator rings and stainless steel nuts.

    PN: BDE-214, Add 3rd Element to Adjustable VTCs, Price - $67.50 per pair

Optional Hard Anodized Front Covers

    Nissan discontinued the front VTC covers for Late type VTCs awhile ago, so we have made these slick 6061 aluminum front covers and hard anodized them to protect from the spring wearing into them. Includes two covers, o-rings, and stainless steel screws.

    PN: BDE-202, Add Front Cover to Adjustable VTCs, Price - $55.00 per pair

BDE does not include VTC front covers. When shipping your cores, keep your VTC front covers and hardware to re-use. Late VTC front covers are different than Early front covers, AND, Late front covers are no longer available from Nissan.
