my brother in law has a Mondial with the same basic unit as in the thema 8.32.He wants to use 8.32 timing belts due to better quality (later design) but the tooth profile is different.This implies changing the pulley wheels to 8.32 ones .How can I find out if the ID of the holes in the pulleys is the same as the ferrari ones (do they fit on the shafts ?) and is this a realistic conversion or are we missing something.I don't have a handy 8.32 engine to measure.

Hi,

I hope that there are many more knowledgeable people on this forum than I, but I do know that on a 308/328, which has the same engine as a Mondial, there are pulleys not only on the ends of the cam but there are also two low down on the engine which drive the cam belts. So i guess my point is, if you have to change the pulleys on the end of the cams presumably you also have to change the ones low down on the engine?

By the way, meant to say that I thought you were going to refer to the test in Car magazine comparing Mondial and 8.32.

Hmm yep , that would have been more interesting i guess but I haven't seen it.
We owned a 8v thema turbo for some years but I have no experience of the 8.32 engine.I will check with my brother in law (BIL from now on) for the pulley arrangement on the Mondial.

correct me if i'm wrong as i am no expert but i'm sure the 8:32 engine isn't infact a 308 or ferrari engine, it was made under licence by ducati for ferrari/lancia, i'm sure someone told me that virtually everything is different ie crank cams etc so if this is true i doubt the parts would swap over, don't take my word on it as i am no expert Huh?

Could be true, sounds very likely in fact but I will investigate further.
thx

I recollect the engine was built by Ducati based on the 308 engine, but modified with different crankshaft offsets to original at 90 degrees, not 180 degrees which is apparently usual on Ferrari engines, so other components may be different too.

The Automobilia book "Lancia Thema 8.32" printed 1986 ISBN 88-85058-50-7, States.
"Derived directly from the engine of the "old 308 sport coupe: 
90 Degree V8 with 2927cc (81x71mm) and a compression ratio of 10.5:1. Top power 215 HP at 6750 rpm and a maximum torque of 29mkg at 4500 rpm.
Valves, four per cylinder, driven by four overhead camshafts, two per bank. Bosch KE3 Jetronic electronically controlled mechanical fuel injection specially designed for this engine. Marelli microplex electronic ignition.
It is thus structurally identical to the 308, but the 8.32's engine has undergone some modifications to adapt it to the "softer" character of the sedan.  The crankshaft now features connecting rods offset 90 deg to each other (a "cross" shaft rather than the 180 deg ("flat " shaft) as usually found in Ferrari engines.  This creates a reciprocating relationship between the power strokes (firing order) of the two cylinder banks, making for more fluid operation and eliminating the nervousness typical of sporty engines".

Further.
" The Thema's five speed gearbox has been partially modified, in the primary shaft and synchronizer bearings, fith gear is "Multiplied", i.e. with the drive ratio below 1: it is a drive gear, so that top speed is reached in this gear."

"The friction now mounts a 230mm disk, and the control has automatic play recovery according to disk wear"
Very good quality book even though only 84 pages.
