Hi guys.

As the title says, i have a S1.5 Dec95 and was wondering which skyline had VVT. my engine is a series 2, as my mate has a series 1 and it looks completly different.

Can somone shed some light. Also if it does have it, when does it kick in ect.

Can somone point me to a good webpage to readt about the R33 VVT, i did a search and nothing came up.

All R33's had exactly the same variable cam timing, in that (I think) the exhaust cam is retarded 2° between just above idle and until ~4800rpm. Someone will correct me if I'm wrong on the exact details but it's something like that. If you put your foot down, the car should sound different and go noticeably better once you hit 4800rpm or so. This is the cam timing doing its thing.

Anyway, R33 VCT is a static cam timing (ie it's fixed at either 0° or 2°, it can't do anything in between) and is activated purely by an RPM switch, it wasn't until the Neo engines in the R34 that the RB had constantly variable cam timing, meaning it could be adjusted to any value within its range and could do so at any rpm.

So the short answer to your question is all of them lol. The visual difference between your motor and your mate's (if they're both stock) is that his will have the ignitor box at the rear of the coil cover (black plastic box behind the stock BOV), yours will have a plug in its place. If either engine is modded then that will also explain differences between their appearance :laugh:

TPS are also different.

    • From my youth: GTi-R clutch change is a massive pain. The gearboxes are fragile? But the car is super cool and I want one 😢 
    • Remember this is 1988 tech.
    • Driveline vibration is resolved. I ended up loosening all my engine mount and trans mount bolts, giving it a good shake then retightening everything and it's gone... Let's just say I was surprised that fixed it.  I've been happily driving it around again but unfortunately put zero time into my direct port/constant pressure WMI setup. I'm on vacation next week, so I'll try and finalize it then.  On a different note, I spent all week fuel/ignition mapping 2x 216L V16 engines. Turbo's were burning glycol and we swapped them out for larger units. We also had planned emissions testing on site, so I figured I'd be there the same week to use their instrumentation and massage any emissions issues out if needed. This was a first for me. Fuel management is similar in certain ways to automotive (i.e air density as load variable) but very different in others. It's all PLC based and AFR's are controlled by air and not fuel. They use a control valve between the turbo and air manifold to control pressure which in turn controls AFR's. Due to this, target AFR tables supplied by the OEM are in pressures and not mass which really through me off. They use air pressure vs fuel pressure tables. I also relied on an O2 concentration sensor the emissions team had in the exhaust. Ignition timing was also all over the place and we were losing a fair bit of power. They're now happily sitting at 16-40BTDC depending on load. We were making about 1600kw at 900rpm at 90% load. Engines were running a lot smoother as well.    
    • heh, aint no R32 ever meeting modern targa cage rules unless the driver is veeeery short OP, good luck with the sale, since its already in the land of freedom I'm sure you will find a good buyer.
    • meh, it was a good video, clear about the issue and how he dealt with it. A bit heavy on the RTV and very brave to put an RB in anything without rebuilding it first, but otherwise I thought it was good Dose, I'm not sure that having the pickup forward is a big issue; yes of course the oil could shift under brakes but the sump should never be empty enough for that to be a problem (unless you also have a higher volume oil pump, and that oil can't return from the head to the sump quickly enough)
