Hi guys

Is it true that the 1600 and 1300 engines are exactly the same except for the bore size. If thats the case, can I purchase a set of Piston and barrel assmeblies and just bolt them onto the 1300.

I presume the pudhrod tubes and rocker gear and head will be the same, except maybe the combustion chamber size could be a little bit bigger on the 1600 due to thye extra bore size. If thats the case then all I need to do is get the grinder out and open up the chambers and cc them and I can put the CR to where I want it.

Am i correct.

Thanks Trev

So what is with these 87mm big bore kits they are selling as a supposedly bolyt on upgrade to 1641 cubes.

Bugger, I thought $400, i cant buy pistons, rings and rebore and hone for that price.

Oh Well

What is boring out the heads, I am familiar with cyl boring but never heard of head boring. Valves are smaller in the 1300, so does that mean i just grab a 1600 set (or any aftermarket) of int and exh and fit them, i presume its just simply opening up the seats to accomodate the bigger valves like on all other types of heads. The springs and retainers should be the same though.

This head boring, do you mean just opening up the chambers to reduce the CR due to the bigger bore.

where the barrel sits inside the head has to be opend up

you will have to remove the valve seats and replace with bigger ones

you would be better off just buying a new set of 1600 heads much cheaper

i had a set of pistons and barrels fitted to my 1300 to make it a 1640.
mechanic showed me that the heads were cracked in various places so got new ones to suit.

see.... air and water do mix 😉
