RaV6

[Paul Woods]

Morning Sir Chris, yes the auto box will bolt to the 3vz, but there the good news ends.

Oddly even though the 3vz is in auto form in the Camry, it becomes a nightmare when trying to make it auto in anything else. The reason is down to your ECU, in the Rav it is taking inputs from the engine as well as gearbox and decides shift points/timing retardation (not to be confused with Mrv6) , torque convertor lock up and lots of other auto voodoo i don't really understand (or want to!)

Now if you say, ok lets ditch the 3s-fe auto ECU and use the Camry one for everything, there are compatibility issues between that ECU and the Rav autobox, ratios will differ, plugs won't fit and again a whole host of other crap.

It might be possible to retain both ECU's, let the camry one run the engine and the Rav one handle the box, but you would have a wiring nightmare!

The only auto V6 in the Uk uses the Camry gearbox, but you cannot do that in the Rav unless you want to build a pure 2WD, but then that sort of becomes pointless.

Sorry it's not better news, i'm not saying it isn't possible, but i've been asked many times to build an auto 3vz Mr2 and refused for all of the headaches above.

Nightmare mate!

EDIT: The Rav4 has two cupholders by the way :)

Ploppers.

I thought there were a few auto V6 twos around, shame it wouldn't work in the Rav.

No, only one and that uses the Camry autobox, still it's got 2 cupholders!

Ian,

You must have missed it, but when you anounced you had bought a Rav4 Mr Woods said "stick a V6 in it" or somthing like, which got me asking questions about it. I'm surprised you didnt shove the 3VZ in anyway as you had it to hand!

Cant wait to see this in action, i know its not exactly an MR2 but it would be a fab alternative for the winter months!

Chris.

Hi,

Unfortunately I sold the engine before I got the Rav - I was using a ford escort van while I was dismantling the mr2. I bought the Rav when I had to get rid of the van a few months ago - it turned up for a sale at a garage just up the road from me so was ideal. :D Has a tow bar too which was usefull for getting my borthers kit car to it's IVA test, and for helping out to recover mine when I decided to modify it unintentionally. :P

Ahh well - never occured to me to keep the engine for a rav until after I'd sold the engine and got the rav.

Fizzy some rav4 owners take an easier route and just stick a 3s-gte in them, there's one guy on the Rav4 forums that has two of them, so if the rear diffs take 3s-gte power (one of them running over 300bhp) then we should be fine with the V6. The gearbox is an E series and the clutch is also Turbo spec, i've also been told the drivetrain is good for 400bhp which makes things interesting.

Your diff lock button is for the transfer case diff, that's what locks the rear wheels to the gearbox and makes it 4WD, when not used your rav4 is FWD only.

Gouky for gods sake man look at the size of that trailer! <shakes head> :)

how does the center diff work then? since there's a 2wd mode, i assume that the layout looks just like the gt4 except there isn't actually a differential for the center that way it can engage and disengage the rear?

does that mean it uses the small inner splines(gt4) or the large inner splines(mr2 turbo)?

they have an auto 2gr in the rav4 in the US. it should be a drop-in swap. the hard part would be to get the parts.

[Fizzy]

Well - I don't think the 4WD drive system is adaptive on the Mk1 Rav at least. Mine has "all time 4x4" on the back and general consensus is that it's constant AWD. The diff lock just locks all the wheels for better traction. Can't go around corners while using it though...... ;o) Not sure if there is a difference on the SWB model?

On later models I've seen them available as 2WD or 4WD, so perhaps they starting making it more intelligent with load balancing...

I would love an auto 2gr rav 4 I wonder how hard it would be to buy a crash damaged one and transfer the bits over to a uk one, some thing to look forward to me thinks a future plan or a gt4 2gr supercharged lol.

And gouky mate I love your trailer wish I lived over there, just the beer I couldn't live with but the mountain dew mmm we get it over here but doesn't taste the same.

[Gouky]

"how fa$t do you want to go?" anything is possible and for the right price I'm even your guy for the job. but it would not be economical. :)

a supercharged 2gr gt4 would be insane. i like your style.

but what i'd rather see is a 2AD-FHV (diesel 2.2L d4d) with a different turbo and a bunch of boost. i bet you could get every bit of 300hp to the ground with that and have good fuel economy to boot! the nice thing about the diesel cycle is you don't have to worry about going lean. just throw more air in until you're happy or until the ECU stops adding additional fuel. if the ecu stops before you're happy, turn up the fuel pressure a bit, if you're still not happy, use an EDM machine to make the nozzles a bit bigger.

Flappy paddles to control the gearbox.... job done.
