Hi all, looking at the 2JZGE motors, I was curious to know what exactly are the main differences between them....
From my searching I found the VVTi has over the non VVTi:
>10.5 Compression Ratio vs 10.0 >VVTi intake camshaft or whatever >Sportier headers? >230hp/304nm vs 225/284 >Improved gas efficiency >Max torque at a lower 4000rpm not 4800rpm
Is there anything I missed as a possible advantage? Any thoughts from actual vvti 3.0gt owners? Cheers

I'd say go for the VVTi Mike - I would have if there had been any for sale when I was looking. I'm still undecided on the 97 factory body kit, but I think I could have lived with it to have the newer technology in the engine.

No, it was initially $6995 plus on-road costs, which was basically just licencing and servicing as they had already VIN'd and WOF'd the car when they imported it. I very carefully went over the car and couldn't fault it, and was very suspicious as every JZZ31 I'd looked at in Auckland was in poorer condition and at least $3000 more. They had a white '95 TT on the lot at the same time which was around the same price and in OK condition also, but after driving it in the wet it was just scary, plus it was white (which I don't like), farty canon exhaust, and no sunroof pov pac.
Anyway I told them if they would get it road legal I'd come back the following weekend and pay cash, which they agreed to (doh! Should have offered them less money too!) - paid a $500 deposit so they knew I was coming back, and it was all done. The next weekend I went back down, car was registered, serviced, and groomed - which I hadn't even asked for! Really top guys. Since then my Sister in law and my Mother-in-law have both bought cars from them, both times unbeatable deals, and both times faultless service.

Mike....i like the VVti, very smooth and quick. 97 model looks very classy including the taillights and factory body kit, elegant too. are you looking to get one? I might be looking to sell mine soon cause just got promotion at work with a company car, now struggling with parking place. (just got it lowerd last month and got the promotion next week...so a bit of good and bad news at a time

Just curious Matt, Forgot to ask the other day, If you did the foot and brake launch technique in yours with the new wide wheels from 0-100km/h what sort of time would you expect to achieve?
Would it be able to keep up reasonably close behind my old V8s stock time of 7sec to 100km/h in this video?
I couldn't quite get an idea on Sunday as I didn't actually floor it completely the other day, maybe 4/5ths at the most , plus more importantly we had 3 people and were going up steep grades...
Personally I would think it wouldn't be to far behind, even though theres a bit of noticeable torque missing down low theres plenty of pick up once the revs get going so I would thing it would be kinda close behind maybe 7.5-8 seconds?

thought....will drive up there ;) didnt realize that you are in Auckland...sorry mate. after owning a V8 then VVti non turbo, it feels pretty similiar to me for 0-80. after that v8 goes quicker i guess. check this out..i had three people too. dont worry about the language ;)

I'd agree with that - I'd pick my old V8 was maybe half a second quicker to 100 - the real difference would be from there on - whereas the V8 just kept on accelerating more or less liniarly, the JZZ31 slowly fades off, so would take quite a bit more time to get to 140 etc.
You can see in the vid really takes quite a while to get to 180, whereas the V8 just rocks on right up to the limiter.

What I must remember according to these videos is that the VVT-i soarers actually not that bad performance wise, I think I'm just forgetting its being compared to the same sized car with 1 more litre and 2 extra cylinders! So theres bound to be some difference!!!
Also to note my clip the car had little gas maybe 15l max and only one driver at 62kg so the car was pretty light maybe around 1620kg or so where as Khans vvti had three people probably at over 200ks, plus 1/2 tank of gas or more so probably around 1750kgs depending on the peoples weights therefore its pretty good. Take a look at my quick graph of the times according to the videos, they are split at 10km/h intervals.

The gearboxes are different.
I prefer the later body shape (or rather kit) although the 94-96 taillights are the best.
I suspect the VVTi would be more economical but difficult to bear this out despite having owned both under similar driving conditions (which are very ordinary for "economy", here) because they have had different wheel/tyre combinations. Our calculated economy for the VVTi is actually slightly lower than for the non-VVTi but it has 225/16/60 (I think) tyres compared to 205/15/65 (I think) tyres for the old car, with around 4% difference in diameter so newer car may be undereading kms.
The VVTi is more docile to drive, I always felt like giving the old car some stick to make it growl. This is the main difference in driving both. Otherwise very similar. The VVTi feels better on the road, but the old Soarer had winter tread 205s which always squealed in corners and when accelerating and didn't inspire confidence (the new owner gave them the flick).
