Outer Limits 4x4 Board

hi,
i have a suzuki sierra took out my 1300 and put the 1600 in, its in and wokring, i have had it in for a few months but the 1600 carby is alot slower then my 1300, it is slow and wont even go 90 kms.
is it as simple as getting it tuned, or maybe the engine is a dud?

i put a 1600 for more power and it is terrible!

Please help its very anoying.

If its not blowing smoke , you;ll probly find its just a tune it needs ,

you didn't put the 1.3 head on the 1.6 did you ?


there should be a noticable difference in performance once its running right .

You will have to explain this better.

Do you have a 1300 with a 1600 carby on it or a whole 1600 motor? If you just fitted the 1600 carby to the 1300, and you don't like the 1600 carb why not just put the 1300 one back on?

Maybe it is running way too rich? How is the drivability?does it bog and misbehave?

Personally, I don't support the idea of putting a 1.6 carby on a 1300 and expecting it to run better at all. I am not aware of 1.3 sierras normally running lean, so I don't know what more fuel is supposed to fix. If you had a cam and extractors, maybe it would help.

Maybe put it on a dyno and get your air/fuel looked at, at least you will know what you have done and a baseline to work from.

From memory dan has changed the whole engine (upgraded to the 1.6 carby engine). He is using the 1.6 head as well. Not sure which carby tho. think it is the standard 1.6. The engine is just lackin power. (according to dans decription)

Wasn't trying to offend anyone but it wasn't clear in the post.

my 1.6 with 1.6 carby has a similar prob. but mine seems to have more low down torque till about 80 then seems to run out of puff. 110kmh is the most i can get out of it running close to standard tyres
I have noticed lots of slack in the accelerator cable even though it opens fully, i also wonder if the fuel pump is different?
if anyone can shed some light on the topic it would help me also

Did you change the cam belt when doing the swap? If so, your cam timing might be advanced a tooth or two if you've got lots of bottom end + no top.

Even if you didn't change it, it would be worth checking the cam timing and ignition timing in case its jumped a tooth.

I've seen a zuk with similar complaints after putting in a carbed 1600, and cam timing was the issue.

The motor should be a night and day differance. I can easily maintain 120 all the way up the hume from melbourne to albury in 5th gear with a stock 1.6 (1.3 carb and intake) and 29's. With a stock exhaust.
Hell I could almost even maintain 100 when a plug lead cacked itself a few minutes home.

hi guys,

sorry about not clearly explaining my problem, as jon said a complete engine swap, 1300 to 1600 carby, 1600 carby.

i replaced the cam belt, i originally thought it was timing as every gear as flat spots, its like it doesnt wanna rev past 3,000 - 4,000.

could it be on 3 cylinders?

cam timing and ignition timing are different things also

I vote timing - I reckon you have the cam timing out. even if it was leaning right out, if you free rev the car if should rev.

Steve.

I reckon it's the carb .. has got a blocked power jet ..

If you have a digital cam take lots of pics from different angles of your carbie, pul it apart and clean that sucker out .. like it was going to be used for surgery ..
If it will free rev but has no power it is most likey not getting enough fuel .. and if nothing elese the carb could most likely used a cleanout after more than 10 years worth of fuel runing through it.

my accelerator cable is really stiff and hard, i need to replace it, could this have anything to do with my problem?

i think the timing is out after replacing cam belt, when engine was first in the car i had some power not a power house, but about simalar to my 1300, talkier then the 1300, but now its just shit house.

There is deinately something wrong .. it should have more oomph than the 1300 from idle to redline.

Where are you located ?
Another memeber may be able to point you to an expeianced mechanic in your area whoul wouled be willing to take a quick look and point you in the right direction as to what is wrong.. Usually only takes a few mins for most simple issues to be diagnosed. (not nesseciarily repaired) ..

Sounds to me like the fuel pump can't keep up with the carby.
Very easy to check the flow ( if you can find the 1.6 figure ).
Remove hose from carby and time over 1 minute how much flows into a measuring jug (1ltr plus size jug ) at about 2500 rpm. than at 4500rpm. or get some tune up shop to do it.
WARNING: have someone standing by with fire blanket and extinguisher.

Pls re-read what you have written .. how do you get a motor revving at 2500 rpm with no fuel line to the carb ?

the fuel bowl will hold enough for the test.

im in Box Hill North

99% chance you made a boo boo with the cam timing then, especially if you say it ran OK in the Vit before you ripped it out. I bet you its 2 or 3 teeth advanced.

You didn't follow a Haynes manual when setting the cam timing did you? I've heard one of the many mistakes in that manual is an error in the cam timing procedure.

The factory service manual has pretty good instructions on how to set it. I can send you a copy of those pages if you haven't got one.

my family machanic did it....
i dont have time to fix anytihng... so if i take it back to him what should i tell him to do...

tune it, check cam timing?

see if that does anything then go from there?
