I'm pretty sure the SAFC is unable to control the VCT. The way VCT works is not like how V-TEC works in Hondas.

VCT on a stock car disengages aroudn 4700rpm where as in a Honda usually it engages at a higher rpm point.

If you're standing in front of the motor, it is on the LHS, where the plenum is.. kind of hard to explain without a photo

and yes NEO has V-TEC control but like I said before Nissan's VCT is TOTALLY different to how VTEC works, so no you cannot rig that shet up.

Car running slow? try disconnecting your SAFC, you've probably have the car running rich as.

it would be strange that VCT would magically die

i dont think we see very often that VCT dies

are you sure it's just died?

has someone been fiddling and then you think it's died?

have you played around with the wiring loom before hand?

just purchased the car a few days ago.... shoulda looked into it when purchasing... but yeh fed the soleniod 12V at idle and while the engine was off no click no nothing...

so this is what i know so far, the ecu is feeding the soleniod the signal (tested the plug with multimeter while reving in gear)

car drives the same plugged and un plugged( can feel power arnd the 5-6K mark but nothing before)

the soleniod is not making and noise when fed 12V

anybody have any suggestions in what else i should check? what could cause VCT death?

      I've heard the Tomei USA head gaskets are decent if you want to o-ring the heads but otherwise not recommended.

      What brakes on R34 GTT(Europe)

      By GTSBoy · Posted

      The 296mm rotors are the R33 turbo brakes. The 310mm rotors are the R34 turbo brakes. The calipers are nearly the same, but not. They're the same caliper but the R34 caliper has longer legs so that it sits out far enough to go over the rotor. The pads are the same for both. When you say, "I bough tsome EBC"....did you just mean pads? Or rotors? 310mm rotors fit under 17" wheels. There may be some wheels without enough clearance though. I can't fit my fingers between the barrel of my wheel and the "corners" of my R34 calipers, but there is plenty of room behind the spokes. This is on Enkei RPF1. You can fit 324mm rotors inside a 17" wheel, but I'd be willing to bet that it would be close to impossible with the Nissan/Sumitomo caliper (using an adapter, of course), because the Sumitomo caliper is fatter than the Brembo caliper that is supposed to go on the 324mm rotors.

      Hi. Can someone tell me what brakes(and mainly WHERE) can i buy brakes on R34 GTT? I bought some EBC which SHOULD go on my car(i have GT but it has GTT brakes) but it does not fit, Brakes are "too" small(296mm) Are 310mm be good or? I have 17 inch wheel so no "big boys" but for me driving i just need one that fits and i can get here in EU/Czech.

      Hey. Very valuable information about pitwork, I will pay attention when buying any consumable parts 🙏 As for the carpets - I got a handful of information from nengun, from which it appears that indeed the carpets for the driver's side are OEM. They are not able to show me any pictures due to the long chain of different sales entities but after I place the order, as soon as the goods arrive at the nengun warehouse from which they will send the shipment to me they can send me photos and if my purchase differs from OEM I can immediately return it / cancel the purchase. I think I will give it a try 😉. Of course i'll let you know what's what as soon as i get them P.s. I know the topic is not relevant to the thread, but both nengun and amayama have these SICK 😍 trunk room lamps available. Do you know anyone who ordered them? I need to have one in my car
