RAV4 2.0 close ratio gearbox into GT4 ??

Lets talk clutches and everything drivetrain related

AFAIK his box will have come from the rav with a 3sge engine, I've yet to find out what years and models that includes.

hey offered a rear torsen for the rav 4. I do not see why one could not just get the final drive bits and the rear diff and swap them into their car.

OK, after some more looking about and thinking:
1) The rav4 diff is not suitable, its just too wimpy.
2) You dont need it anyway, the final drive is done pre-transfer box, just bolt the rav4 transmission right up and off you go.
3) Overall ratios in comparison with a 205 box:
Overall gearing, including final drive looks like:
gear rav4 st205
1 18.62 14.5
2 9.98 8.2
3 6.28 5.4
4 4.59 3.93
5 3.87 3.13

Would make redline speed 120, and first gear (I get about 30 by the redline in 1st) would drop to something like 20mph lol. 70mph motorway cruise would sit you around 3600rpm.

Any luck finding the rav 4 final drive part numbers?

I do not like how low the rav 4 1st gear is for my use.

you can't use the FD without the output shaft as the FD link to the output shaft

A final drive get is ratio from 2 driven gear, one on the diff and the other on the output shaft, without both it won't work

I think a output shatf would be quite expensive whereas a complete gear box won't

And the question is : does the RAV4 output shaft compliant with E15xF inputshaft ?

because i wonder if we can't make a wonderfull mix of every closer ratio from 2 to 5 and keep the original E154F 1st gear ratio

I will do some digging. I used to have a data sheet from back in the day that had ever gtfour gearbox part listed and what was compatible across the board.

I always wanted the Ralley box from japan. One sold on here a while back with a custom 5th gear for ~1,000usd. I think thats a good price concidering how hard they are to find and that it already had the custom 5th gear. (OEM ralley box uses standard 5th gear)

I am currently ok with how close my gear ratios are in my 151f box but I might be interested in a lower final drive since my tire height is mu8ch bigger than stock.

I am going to PM the guy who did the v6 swap and rav4 gearbox in his 185 and see if he can give some input.

3S-FE, sorry. Any 3S gearbox will bolt to the block, though the clutches / output shafts might be a concern.

Howdy folks. :)

Ok, the ravbox i used is from a 2003 model, im pretty sure its the lwb version.
From what i can gather its an E250F.
The ratios i have down as:
1- 3.833
2- 1.913
3- 1.258
4- 0.918
5- 0.775
rev- 3.583
final drive- 4.933

Transfer is geared exactly as the alltrac box, i put em side by side and checked the turns. 2.928:1

Top speed was gps'd at 120mph give or take so another poster was correct in that.
Its deffo a rocket thru the gears and very much a useful option for rally or hillclimbs/sprints etc.

Heres a couple of pics of the beasty. hope this helps.

i have been interested in this swap for a while. my main concern is the strength of the rav4 gearbox compared to the all-trac one. hey 4v6 you should write an article on what you did to complete your swap like step by step, please!

So I take it that there is no issue with the splines on the output shafts? How about the length of the CV axles?

I'm going to be dropping my entire engine to replace the clutch (along with some other stuff) and this would be a very, very interesting "upgrade." I wonder what a 0-60 time is using the Rav4 gearing? I bet it would be a rocket. :)

Hi ummmiono, i already wrote a swap article, its on celicatech. :)

The strength of this box appears to be up to at least as good as the alltrac item, but then it should be.
Im only hypothesising here, but the CS/RC box was an improved strength version of the original st185 box, i believe that its similar internally to that cs box.
It does have a different 5th gear cluster as initially i wanted to swap them over to get a higher top speed, but theyre vastly different in design so no go unfortunately.
Ive been looking for another of these boxes to go with the 1mz motor i have but so far, its no go... :(

MR2 VRI, left axle spline is the same as the alltrac, just pop the original rav 4 item out and click the alltrac item in. Works a treat.
The axle shaft on the right side is more of an issue and you cant use the existing parts. You need either an rx300/highlander rh driveshaft or a combo of the rav inner driveshaft and the alltrac, cut and welded to produce the right item...like this one. :)

holy shit i want one!the only downside i see, if the weights are in fact similar, is if im not mistaken the v6 is an interference type motor meaning piston would meet valve if the timing belt broke which is something i am not a fan of. otherwise awesome. you should be an alltrac god.
