1.6 vitara carby motor into sierra info

[zookster666]

I am after information on putting a 1.6 carby motor in my zook. I already have the motor just sitting around and i would prefer to keep it carby as it will be cheaper and an easier conversion

So i have a few questions.

1.will this be worth the effort for the power gain?

2.the 1.6 litre engine is missing a few parts off the head so i was going to use the 1.3 head on the 1.6 block, will this greatly effect the power of the engine?

3.when using the 1.3 head do i use the 1.3 or 1.6 timing belt?

4.will i need another set of extractors when i use the 1.3 head?

5.should i use the 1.6 or 1.3 carby on the 1.3 head?

6.do i use the 1.3 flywheel and clutch when using the 1.3 gearbox?

7.will i need anything else?

8.what starter motor do i use?

all info is appreciated
cheers jesse

heres some help for you mate, dont take this as gospel as most people have different opinions. I personally converted my sierra to a carby 1.6 back in 2004.

1. Not overally power gain, I ran 31's with standard diff gearing, and could hold 100 on the flat at 3/4 throttle. Noticeable difference on standard wheels though.

2. Doesn't overally affect the overall power, the 1.3 carby is smaller than the 1.6 so it will suffer, but marginally.

3. Unsure on this one as I used the complete 1.6, but I couldn't see it being an issue, just count the teeth on both and look at the difference.

4. If you use the 1.3 head, you will be able to use your already existing extractors, after all said and done the headers bolt up to the head don't they? The only thing that may need modifying is the down tube of the extractors. The 1.6 block is taller, meaning the head is sitting higher in the engine bay.

5. I'd retrofit the 1.6 carby on.

6. Yes, use the 1.3 flywheel and clutch, the vitara one wont fit in the bellhousing very well. Remember you will need an adaptor kit ($200 on ebay)

7. Yes, if you use the vit carby you will need to shorten your standard accelerator cable by 30mm. failing that its pretty straighforward. The sump sits close to the diff, so its a bonus to have raised springs to allow alot more clearance. Same with a body lift, the vit air box will fit easier.

8. Starter motor - use the carby vit or sierra motor. both the same. The efi vit starters are a direct fit but are harder* and dearer* to buy.

Hope this starts you off into the world of conversions mate, goodluck!

* - just my own opinion from my own experiences.

Many other people will have different opinions to what I just said. Thats how it worked for me. I had heaps of trouble chasing info on the conversion prior to doing it, so Im more than happy to help others out, to make it less trouble!

Cheers Superduki.

P.s ive since had a few rides, and my current one is a lwb flatray, which im converting a gti swift motor into, not really for power, but efi reliability!

thanks for the info mate i will start chasing all the parts i need and use the 1.6 carby i have reduction gears so that should help it along with the 1.6

2.the 1.6 litre engine is missing a few parts off the head so i was going to use the 1.3 head on the 1.6 block, will this greatly effect the power of the engine?

what parts are missing? other than the fuel pump i am pretty certain you can cannabilise the parts from the 1.3 and stick it in the 1.6.
The big difference is the 1.6 has bigger exhaust valves, and according to the no1 teamswift.net cam grinder the cam has slightly more lift and duration. On the flip side there is a different school of thought that the smaller exhaust valves are better cause they increase the velocity of the moving gases increasing HP. (that and the 1.3 may be 0.5 to 1cc smaller giving you a slight Compression ratio jump)

I would say take the 1.6 cam and go with the head thats in better condition. (you might need to use the 1.6 cam gear to line up the crank/cam properly)

3.when using the 1.3 head do i use the 1.3 or 1.6 timing belt?

The 1.6 belt, the block is taller than the 1.3l (the heads are same size)

4.will i need another set of extractors when i use the 1.3 head?

if you got the 1.6 stock manifold they will fit on the 1.3 head, if your using the old faithful 1.3l stock then you would most likely have to extend the down pipe as mentioned (aftermarket 1.6l extractors also fit on the same head)

5.should i use the 1.6 or 1.3 carby on the 1.3 head?

Whichever one is in better condition, IF you are going to rebuild it then go the Vit carb, its a mikuni (suppose to be better) the sierra is an aisin. That and the vit one is factory jetted for the engine

7.will i need anything else?

replace the oil and water pumps since the engines out?

1.will this be worth the effort for the power gain?

Really depends on how tired the vit engine is. If its fresh and tight you will be praising the time and effort, if its seen better days, you get the idea..

Might be an idea to put some fresh rings in and deck the head for a small bump in compression.


and just to finish i put a link on 1.3l to 1.6l dyno numbers!

im not sure what condition the engine is in as i got it with the zook i bought i was thinking the 1.3 head for the little bit more compression and had heard that the 1.3 carby was better for power have most of the stuff i need the adapter plate, and probably an exhaust manifold. i have a complete engine gasket kit and i will freshen the engine up

thanks for the help so far guys

the 1.3 revs easier and the power difference isnt huge personally i prefer the characteristics of the 1.3 over the 8v carby 1.6
If i were u i'd sell it and spend the money on the 1.3 with a insky cam, shave the head to raise comp 3/4 of a point, and webber carb
power gain will be fairly decent. just my opinion dont mean to discourage you

[zookster666]

basically im after a bit more driveability on road off road im very happy with the 1.3. I just dont like coming to a small incline and having to back down a gear and also the 1.3 is getting a bit tired. this is the only reason i considered the 1.6 cos it is just sitting in the yard.

The 1600 is way more drivable offroad than the 1300. With 4.16 t/c and 4.8 diffs with 33s and a 1300 I had to select 4 low for the gearing only on certain obsticles but with the 1600 it has way better torgue down low so I can stay in hi range alot longer if that makes sense?
For my swap I think I only used the engine and head its self then I bolted all the 1300 stuff on.
The 1300 manifold will have to be clearenced around the fuel pump but its nothing major and the exhuast will bolt up.
You have to use the flywheel and clutch of the 1300, and I also used the 1300 starter although I had to grind a small part of the rib on the block and a little of the starter casing so it fit up.
Once you get into it its an easy conversion and worth while if you have the engine there.
