1.6 head on1.3

this is probably a dumb question but is it possible to put a 1.6 head on a 1.3??? I hear its the big brother and a 1.3 intake will fit a 1.6 so????

Re: 1.6 head on1.3

if it is a 1.6 8valve head, its a straight swap. the only thing you have to address is the fuel pump. With the 1.6 head, you will have to plumb in an electric fuel pump (usually about $20-25 at all auto parts stores) to make up for losing the mechanical pump in the 1.3 head.

Re: 1.6 head on1.3

This would get you the larger valves. I wouldn't expect any power increase though. and I wouldn't do this swap with the sole intention of gaining extra power.

If your head on the way out though, it makes a good alternative.

If you're just looking for more power from your head, get a good porting job. Suzuki heads are full of squared off flow-blocking angles. If you're having head work done, I'd highly recommend this as a VERY worthwhile procedure.

Re: 1.6 head on1.3

Can anyone tell me the valve face width of the 1.3 and the 1.6 to see if there is enough of a difference to make the swap? I know it won't be a 200hp bolt on monster, but every little bit helps. Also, could the isky cam be used with it(the 1.6)?

Re: 1.6 head on1.3

Glenn-

Does porting the heads makes that much of a difference (I have a 1.6L 8 Valve in my Sammy)? How much does that usually cost? Will porting the heads affect fuel economy?

thanks,

pug

Re: 1.6 head on1.3

Porting the head does make a difference. I feel it is a very worthwhile modification.

Isky cams can be used in the 1.3 or 1.6 heads. It is interchageable. So long as it is not the 16valve head.

The diameter of the valves is not much at all. This is why I was saying, don't do the swap if a power increase is all you are looking for but your current head is working fine. The difference in intake valve sizes can be measured in thousandths. The exhaust valves for the 1.6 head are about 1/8" larger. Not much, but a little.
