Changing The Neo To Switchable Vvt?

Ive asked plenty of questions regarding a solution to my NEO ECU problem. Ive come to the conclusion that I simply cant afford to run the VVT at the moment as ECU's that support it are rare and hard to come by. (I priced up an R34 PFC but at $1400nz + sorting out my cut wiring loom + Tuning fee's- i simply cant afford it).

So, I came across a LinkPlus that was already running on and tuned on an RB25DET for $750. At that price a had to grab it. I emailed Link before I purchased and they said, "It may be possible to just switch the cam timing (all on or all off, like vtec), you will have to investigate whether that would be ok, or just make it worse".

So what are my options now guys? How to I go about changing the Continious Variable Valve Timing to Switchable (like the R33)? Is this even possible?

Also, how will the car run if i simply wire it up and start it as is?

Oh, and the reason i didnt just get an R33 RB25 for my Silvia is that this NEO with 80kms popped up at $1600. I was getting quoted $2500 for R33 25t's so I naturally grabbed that NEO.

Hmm, looks like theres not alot of info out there about this. I guess im probably the 1st person in history who is backward enough to to change a technological advancement in a motor back to its older conifguration, but my current situation forces me to do this.

Can anyone put me out of my misery and tell me if its possible to switch off the Continious VVt? My turbo, exhaust and IC piping fitment are being completed next week and ive got a LinkPlus sitting next to me which im not sure whether or not will be put to use. If not, im back to drawing board. :P

I havent thought of that, i will look into this option aswell. But I will need to find a rare neo ecu, plug and part of the wiring loom. Very hard to come by here in NZ. It seems like getting rid of the vvt is the easiest option, but thanks for the suggestion :P

      MAJOR FUEL ISSUES 25det neo r32

      By 25debt · Posted

      bumping this post as im still having dramas, my fuel pick up is sitting on the bottom of the tank, my pump gets a constant 13 volts through a relay, my fuel pressure holds consistently without fluttering or dropping, yet as soon as im near half a tank of fuel my car starts fuel starving and leaning out, it cant be due to g force as it never pulls hard enough before it starts breaking up, any help would be much appreciated

      Just a thought, was that car and auto at any point of its life? If so, maybe whoever bridged the inhibitor switch/circuit did a not so good job.

      Wife wanted basket things in the wardrobe in our temporary house. Thought about ripping our the wardrobe and fitting the entire IKEA set, but it's a temporary house and we want to move in a few years. So IKEA advertises this as a 50cm unit, however the actually basket and rails measure 46cm wide. Only issue was depth, IKEA stuff is quite deep, where as the builder special junk is super shallow at less than 40cm. Send it, chopped the rails, then offset the mounting holes, job done, happy wife, less shit scattered all over the bedroom. Did the same to the other side too. Also drove the Skyline shit box today, dropped off oil at Supercheap Auto. I didn't realise they only now take max 2x bottles per visit. I visited 2x Supercheap Autos.

      Strange issue RB25DET wont start

      I've seen similar actually in my situation. You never know what tables are attempted to be used when the car thinks it's -99C or +200C. The fail state is not usually that extreme but you know what I mean - it was in my case though! This is where being able to read all the sensors is useful cause you see this stuff really quickly.

      The above is very important. However as long as you keep timing relatively low, it's plausible to make your own knock ears and plausible to learn to tune with a modern ECU that can do wideband O2 correction like a boost controller. I mean if you only have one viable road to even drive the car on, learning to tinker to this level may be worth doing given you can't do much else with the car...?
