Safc Neo + Vct?

[Pr0j3kt_Supra]

hi everyone basically can anybody point out where the VCT plug is so i can diagnose if it is working or not by unplugging it and my second question is can my SAFC neo be used to control my VCT?

thanks and sorry if this has been covered before didnt find anything with SAFC and VCT

for R33 RB25DET S1.5

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.

the SAFC wont affect the VCT in the R33 at all

[PM-R33]

Yeah im confused why you are mentioning VCT and SAFC in the same sentence. They are completely unrelated.

[paulr33]

agree

[Pr0j3kt_Supra]

sorry for the confusion... ok currently the car feels sluggish with no response so i want to check where the VCT plug is i want to make sure the VCT is functioning....

second i have a safc NEO...the neo features VTEC control thoght maybe can rig it up to make it work with the nissan VCT

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.

[Pr0j3kt_Supra]

no SAFC connected yet.... vct plug found and unplugged sdame performance so vct no functioning :S will do more diagnosis

[Pr0j3kt_Supra]

did check plug has signal .... gave the soleniod 12V and no click?.... is it ment to make an audiable click when engaged? sigh looks like my soleniod is busted any body know how much these are worth? cheers

[paulr33]

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?

[Pr0j3kt_Supra]

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?

[PM-R33]

Very rare to kill the VCT so no idea what would have caused it. Most solenoids only fail due to a blockage.

[Pr0j3kt_Supra]

mmm so could be simple blockage havent taken it off yet cant find a big enuf spanner hahahha so give it a good clean and see how we go?

[Pr0j3kt_Supra]

thanks PM-R33... was just alil dirty after all had to give it a degrease and clean, works good now thanks

[PM-R33]

Too easy man. Like i said, its very rare for the RB25 VCT to fail. Glad you got it sorted.
