You can do a search if you want. Or I could just give you the answers you need.

Here is the thread you are going to want to read first:

https://www.pirate4x4.com/forum/suzu...der-heads.html

The simple answer is yes, you should do it if you can get one for a decent price. larger valves means more air in and out which can equate to more top end power. They also tend not to burn as easily as the 1.3 valves do because of better heat dissipation. The 1.6 8v cam is actually pretty decent at picking up any torque lost by the bigger exhaust valves. However, if you still want a different cam you can use a 1.3 cam as long as you also use the 1.3 distributor housing.

Wouldn't it be better still to just go to the whole 1.6?

Also, more than likely the 1.6 head will not have the provisions for a mechanical fuel pump.

It will not have the mechanical pump provision. but if he is putting a turbo on it I suspect he wouldn't be using the stock mechanical pump anyways.

As far as swapping the whole engine? There is still a cost difference involved. Like an adapter kit and possibly a starter. The cost of the complete engine or even vehicle v.s the cost of a head only and time to pull both the engines. For a %20 gain in HP it can be worth it. But also the 1.6 block is known to be a bit weaker so maybe with the turbo it wouldn't be best. Or just swap heads to the 1.3 block for minimal cost for a bit better flow with the turbo.

What size jets are you starting with? What will your timing setting be? How will you set your timing for initial start up? What brand AFR gauge do you have?
