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
sorry mate i have never done this but it's not that easy
the stroke is the same 69mm but there thats about it the heads wont fit something about the studs not fitting
someone else will be able to tell you all the work to do it
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
the barrels wil fit into the block but you will have to get the ehads bored out
Valve sizes are smaller 4 the 1300
crank is same carbie is smaller
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
Thanks VW54
Never knew the barrell sat inside the heads.
Thanks cheers
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.
