any 1592cc experts?

[cbrewer13]

i currently have a clymer and a haynes manual, and although the clymer was published in '73 and my car is a '73, and it also makes note of the fact that the 1592cc exists, it does not, however, offer any kind information about it.
it seems to me that the 1592 is closer to the 1800 than the 1600 in the details. this from the fact that it's a 132 series motor, it uses head bolts instead of studs/nuts, the dizzy is on the passenger side, and it's got no emissions fitting in the head.
basically, i'm wondering if it's wise to use the 1800 as a reference.
aside from the shorter stroke, smaller bore, and that it's got a dhsa3 on it, are there any other major differences i should be aware of?

It is the same family as the 1800 engines but I believe it was only offered in 73. Lucky you! The 1608 and 1438 were of another family. I have some specs on that engine in my Fiat service manual if it will help you.

The Bore size is the same as the 1438 and 1608 but the stroke on the crake is 79.3 mm instead of 80 on the 1608
not sure what all the fuss was with the changes over at Fiat . If i remember correctly the head water passages
were different so you could not use the 1608 head on the 1592 . Thats about all i can remember at the moment .

cbrewer13 does your spider have a 1592 cc or your just looking for answers, why Fiat decided to screw with
the numbers ?

my '73 does have a 1592cc. from what i've found out about it, the 1592cc was made to comply with the 1600cc rally class regulation. it is based on the 1756cc that was found in the abarth rally car from the same time.
they had to put the 1592 in a certain number of cars to qualify to race, so bingo bango, we (i) got an oddball.
as far as i can tell, it's slightly less powerful and harder to find parts for than the 1608cc, but at least it has a story.

As far as the head goes, the 1592 head is very close to the 1800, only differences are the lack of air injection ports on the head, slightly larger water passage between cylinders 3 and 4. It may also have slightly smaller intake ports, but I can't confirm as mine has been ported. A head gasket for the 1.8 or 2L should work for the 1592 head. If the block is same bore as the 1608 then pistons rings and bearings for a 1608 should work in the 1592 block, Hardest part to find would be the rods.

I jhave never worked on a 1592, but my buddy put one together for his B coupe, only to discover that the engine mounts weren't located in the same spots! He had to do mods to get in there, but he did so since he had spent quite a bit of mney and time building up the motor.
