Hey guys ive done a bit of reading on this and some people say that the 1ltre doesnt have enough power to pull in fifth gear, just wondering what the general consesis of fitting a five speed to the one litre is? Also does the sj413 five speed bolt straight upto the transfer case and 1litre motor?

I also own a suzuki super carry which is the one litre engine with a five speed gear box and it sits fine at 100k, is it the ratio on the transfer case that would make the difference? Is the one litre engine in my supercarry the same engine in my sj410?

Just wondering as it doesnt seem like there is an excess of 413 engines with five speed gear boxes so was just wondering if it will do with only the five speed, pretty much all I wanna do is be able to sit at 100k with traffic and stuff to get up to the mountain from christchurch in ski season.

Thanks guys

Hey mate, i'm 98% positive that you cannot bolt a 413 5 speed to a 410 motor. Your better off looking for a 413 engine and 5 speed box and dropping that in as the slight power gain and the extra gear will be beneficial. I have a 413 with 30" muddies on it and it only just does 100k. It pulls 3500rpm at 100 so its no wonder that the motors die a slow and smokey death lol. The only thing that you will need to change will be the output on the 413 gearbox to your 410 transfer case, im not sure how you will do this as I have not done it myself. But Suzuki's are little and not hard to work with!

The Super carry motor will most probably be the same block and pistons etc maybe even head but will most probably have a different oil pickup and sump arrangement. I cannot comment on whether it will be the same carb as i have never seen one. As for the 5 speed box on your super carry i'm not sure that it will work in your 410. But hey all your can do is look at them measure up mounts and look at output splines and bolt spacing to see if it will work! Good luck!

Firstly 100k in a SJ can be interesting to say the least.
my 413 pulls about 3500RPM with 30" Tyres at about 100k ,same as Mr O, but only down hill.
If you want to go fast get another truck or re-power it with a 1600.

To bolt the 5 speed gear box to the 410 transfer , you need a 413 short drive shaft (Gear Box to transfer) and just change the flange at the transfer end to a 410 one. 410s have a smaller flange than the 413

Does the 413 box bolt onto the 1000cc?

As far as I know you can't bolt the 1ltr to the 1.3, 5 speed

410 motor will not bolt to 413 five speed box,
different housing, shorter output shaft,
if you fit a 1300 motor and box there will also be some other changes

My daily driver is a 1992 Suzuki Cultus G10 970cc 3 Cylinder, 5 speed manual, air conditiong + power steering. It works out great on gas and cruises fine at about 3200RPM @ 100km/h... the engine is east west thought not north south so no chance of putting a gearbox from one of those on and may be the same for the carry? (just on a side note i've been told the rear springs out of a carry give a 413 a few inches of lift)

As has been said it is not easy to do... but i have heard if you grind something and something a bolt something etc the 413 to 410 can be done but its not worth it. You'd be much better to bolt a 1.3 engine and box in there... There was a 5 speed box on them in like austria or something but are very rare and never heard about one in New Zealand. So chances are your never going to see one.

Off the top of my head (i did work it out once) putting a 5 speed box in one would make the 410 rev at about 4500 @ 100 vs the stock 5200 at 100. Another thing to think about is i don't think they had the brake booster on the 410s and some even had drum front...

An alternative would be to get bigger tyres for the 410 (and hence increasing the gear ratio but the speedo would be incorrect) i think a stock tyre to 30's on a 410 makes a 10% difference ie 90km on the speedo = 100km on road = approx 4700rpm @ 100km road speed. Another thing which would result in a minor change would be to put a 413 transfer case into the 410 which would increase the ratio a bit too.. you could probably get it down to about 4500rpm at 100km/h (but there would not be much power and your offroad low range would suck even more)

Note all these changes require certification for the truck too

Just found some numbers and a early 410 transfercase in high range is 1.590:1 and a 413 transfercase is 1.409:1
ie a 13% difference... and upto 30inch tyres from the stock 27" tyres is a 11.11% difference... so that makes 24% difference in total.

So that would be like 4000rpm @ 100km which is acceptable...
Catch is your lowrange offroad would also be much higher...

From what I have heard you can convert a 4 speed to 5 speed if you have a later 4 speed (Series 3/4/5 11/84 on) trans and a 1.3 5 speed trans. Take the case assembly, the upper and the lower, the input shaft and the input shaft bearing retainer of the SJ 410 and install the case extension, the forks and the rest of the gears from the Samurai transmission. The hole in the floor needs extending about 1" and the crossmember mounting will also need attention as the Sammi trans is longer than the 1.0. Also the rear of the case needs some machining for a bearing for the 5th gear.

Santana in Europe had a 5 speed that bolted up behind the 1.0 and I think Maruti also used it. The Carry version won't but I have heard that the 4.0:1 first gear can be swapped in.

Fitting 31's dropped my revs around 1000rpm at 100kph but the off the line acceleration suffered a bit.
