suzuki 3.52 final drive (for Geo Metro)

am wondering whether it is possible to install a suzuki (5 speed manual) 3.52 final drive transmission in a 1996 geo metro that has a one liter engine. can the components be swapped from case to case ? or would it be more reasonable to use a 3.79 final drive transmission any input would be greatly appreciated. thanks..

Define "more reasonable."

I did the 3.52 swap into my 1.0L 1998 Metro. I just put in the entire transaxle ... the gears are otherwise identical.

thanks for the response. very much appreciated.. more reasonable / sensible is what was meant.. you didn't have to perform any modifications at all ? were you able to use the same drive axles as well ? was under the impression there'd be much more involved.. anyway thanks again for sharing..

It was pretty much plug 'n' play for me.

Odo/speedometer is now off, and I wouldn't recommend this to someone who did a lot of driving in a hilly urban setting. (Noticeably more clutch slippage required for a 1st gear start, and general decline in acceleration ability.)

For the type of driving I do (mostly highway) it was an effective mod. I even wish for a taller 5th gear still.

thanks for additional info.. again very much appreciated.. what year vehicle did the 3.52 come out of ? how far off would you estimate the speedometer is ? how many rpms are you turning at highway speeds ? if you have info would very much appreciate a reply.. thanks again..

You should be able to swap over the speedometer gear from the old transmission to keep the speedometer and odometer as accurate (or inaccurate) as they are now.

Yeah, I keep forgetting that. In my case, the tire circumference of the donor car was also different, so things would have still been off (but by less).

The only difference is the speedo driven gear, tire size on the donor doesn't matter. I've never checked if the 1995+ cars have yet another driven gear size.

the speedometer drive plastic gear with 18 teeth is the same on all(fixed on diff.).the differents are only on speedometer driven plastic gear (smaller on which is speedo cable) 16 teeth for 14"wheels and 17 teeth for 13" wheels.if you put on car 14" wheels you must have speedometer driven gear with 16 teeth so the cord can spin faster for speedometer because with bigger wheels for one turn car cross larger way.
