VG30DE(TT) Adjustable VTC Pulleys
Compare to Early VG30DE(TT)(Z32 ’90-’93)
Beginning with the 1994 NA model Nissan changed their VG30DE VTC pulleys to a Late multi-piece unit with a separate outer drive pulley; the TT followed suit in 1995. At the same time, Nissan offered an over the counter Service Replacement VTC for Early type cams which was based upon the this Late assembly.
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. +$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.
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. 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.
