Ok so I might have an idea if it works I'll do it here it goes a 1.6 bottom end combined with a 1.3 head and carby will this work? Any power gains? And the most important will it run??? Cheers for the help fellow zookers

[11_evl]

Yes it will work.
And power will be noticeable
You will need a longer timing belt and adaptor plate for gearbox and engine mounts

[matfan]

and you'll need a 1.3 sump and modified pickup

[Daves4wd]

Do you know what these are worth??

[want33s]

Sump and pickup... $50
Engine mount and bellhousing adaptor... $200
T100 timing belt... @$40

[zooky08]

I have a 1.6 bottom end with 1.3 head and carby.
You differently will notice power gain.
I would tune the carby for the 1.6 bottom end, mine is very thirsty.

[Daves4wd]

Ok then is it straight forward?? I just spoke to Allan at parahna he said there's cutting and welding in envoled plus he wants 400 500 for a second 1.3 I'm just want it back on the road cheaper and better if that can happen hahaha when I get home I'm going to pull off the head hopefully and post up pics I'm not to good with knowing if it is in good nick or not all thus help is great thanks guys

[matfan]

My understanding is that it'll work, I'm about to do the same thing. The only other consideration that I can think of is that your exhaust system might not reach the manifold. That's just a guess, I assume someone will correct me if I'm wrong.

I've read a couple of other threads that suggest rejetting the carb to suit.

Good right up here

I have a 1.6 block with 1.3 head and had the 1.3 carby rebuilt and tested by a carby specialist. After testing, he removed the oversize jets and replaced them with standard jets.

Here is the 'wierd bit'. With the standard (smaller) jets and a rebuild it actually used more fuel!

That makes my head hurt.... can someone shed some light on why that may be?

Where's the extra power coming from?
Is the chamber smaller on the 1.3 upping
The compression?

Longer stroke and more capacity from the bigger bottom end.

And I'd say power would be fairly similar to stock 1.3, but torque would be improved.

[FullyZooked]

Just install a complete G16A? Am I missing something?

Do 1.3lt heads have smaller chambers upping comression?
Do the 1.3lt inlet manifolds flow better than the 1.6?

[11_evl]

Smaller carb. Bigger motor. More air flow thru carb draws in more fuel thru out the rev range

Certainly feels that way in mine. No extra power feels like it has a bit more torque at lower RPM.

A 1.6 top end on the 1.6 block would be even better.

I know that the carby specialist recommended the standard jets for you but is it possible that the larger jets would show an increase in power?

[Daves4wd]

I thought bigger jets and a good tune would fix the drinking problem but I don't know much about this so I'll take your advice for it there's a few combos I wouldn't mind trying with engine but I'll see what happens thanks for the help legends

[stocker]

Just putting it out there, but i have a 1.6 Carb for sale for 400bucks it runs fine, why waste the money for minimal torque gains

Go 16v efi, you will not regret it...

[2stroker]

People have been putting 1300 heads on 1600 bottom ends for a long, long time. They usually think that the car goes heaps better but that is usually because the old 1300 bottom end they took out was totally stuffed.

In the end a 1300 head, manifold and carbie on a 1600 block may be better than a stock 1300 but it will not be better than a 1600 block with a 1600 head, manifold and carbie.

Yes the 1300 combustion chamber is slightly smaller 38.2cc compared to 50.2cc but the 1300 head, manifold and carbie flow so poorly compared to the 1600 head, manifold and carbie that the compression difference is negligable in relation to performance gains.

[stocker]

shh... stekky return to smart ass island with your G16B...

If he is not in the know how of Electrical side of it... a G16A can be alot easier to install

[Daves4wd]

I haven't got the cash for 1.6 injected if I did this here post wouldn't be here hahaha where abouts is this 1.6 carby I read?? Is it smokey?? Is it a whole engine? Ie carb dizzy alntnater so on?? Cheers for the help

[stocker]

Everything is on it. and it runs just fine, i don't believe it is smokey but then again i haven't had me head up the tail pipe, it is a complete engine still in a running vitara, just the rust has had its day and its way with the car. The engine is based in sydney, and if you want it it will be organise your own freight or come pick it up, for freight, i'd be happy to put it on a pallet and chock it up for transport on a Skid.

[Daves4wd]

Well the head is shagged pistons shaged so it's a full 1.6 or1.3 now hopefully 1.6 carby thanks fort he help guys most of the engine is out not much left now just need a half decent 1.6 and it's full steam ahead is it all the same wiring or different and is there a thread about the different wiring and how to do it??

thats for a G16B, i believe you will need to purchase a kit from BenT
