Title: Sport 131/132 gearbox question.
Post by: 106usj on January 20, 2010, 04:27:52 PM
The spare gear box i have is from im quite sure a 132 2000tc or possibly the later 131 Supermirafiori 2000tc with the angled gear stick.
Q, if i ever have to change my original sport gear box due to failure. Will the spare 132 box i have work on the sport.?
As the Sport gear box has a different set up with Abarth quick shift.
 and the straight stick.
Q,will the main gear box be the same and just a case of taking the abarth gear change and stick set up of the existing box and fitting it onto the 132 box ?
As i have looked at a picture of my spare and a picture of a 131 sport  box.
The spare does not have the back section with the Abarth stamp and straight gear stick.
Thanks

The later 2000TC Super had a remote shift like the Sport - just didn't have 'ABARTH' cast into it, so if the gearstick comes out at a jaunty angle could be any smaller engined 131 or a 132 box or even a 124 or 125 box come to that.

I recived  pics tonight of the engine from my mate.
 It says 132 on the engine block its a 132 2000tc engine so the gearbox was sold to me with the engine so it will be a 132 gearbox.
So my question of will it work, still stands, Anyone ??

As far as I know the gearboxes are the same except for the gear lever. Off the top of my head I don't know if the gear ratios are exactly the same but the box should fit.

132 on the engine block doesn't mean the engine came out of a 132, depending on the numbers and letters after the 132 it could be out of a 124, 131, 132 or a variety of other types. Not necessarily 2 litre either!

106, too many uncertainties in your first post for anyone to say for sure.

The engine 'type' should be stamped on the block near the engine number. This will be a quick and clear indicator as to the size of the engine.

As I was alluding, and Taz confirmed, having 132 cast into the side of the block tells that it's a 132 'series' engine and could in all reality be a 1756cc from a 124 Sport/Spider, a 1995cc from a 132, 131 Sport or 131 Supermirafiori. In fact it might also be a 1592cc from a 132. Check the engine type.

132 engine type numbers are as follows

132 - 1600 and 1600 Special                    132 A.000 (1592cc)
132 - 1800 Special                                    132 A1.000 (1756cc)
132 - 1600 GL and GLS (early models)     132 B.000 (1592cc)
132 - 1600 GL and GLS (later models)      132 C.000 (1585cc)
132 - 1800 GLS and ES                             132 B1.000 (1756cc)
132 - 2000                                                132 C2.000 (1995cc)

Even if the engine is proven to be a 2000 from a 132 then there is the chance that the gearbox could be from an different rwd Fiat and was made to fit by changing the bellhousing.

If you are certain that the gearbox is from a 2000TC 132 then the internals should fit the 131 Sport gearbox but I believe the 5th gear was 'taller' on the 132 to allow motorway cruising without making your ears bleed.

Simon.
You are right my mistake, i need to check the numbers above the oil filter to confirm as i have only pictures i cant confirm but i am collecting the engine soon so i wiil post when i see it.
As for the engine block number it is 132 DB 2A B i can see that from the picture I think the last letter i think is B
Thanks.


Title: Re: Sport 131/132 gearbox question.
Post by: mirafioriman on January 21, 2010, 09:50:45 PM
So the engine is a 1600 T/C then?


Title: Re: Sport 131/132 gearbox question.
Post by: 106usj on January 21, 2010, 10:21:18 PM
Dave i  double checked my picture and amended the numbers on my previous post as they are on the block sorry for the mistake.
I hope when i get the correct engine number  and type above the oil filter and post detailed pictures of the box someone can confirm the gear box question.
Until then its a guess like Simon said.

131 2000 sport blocks have B2000 on them


Title: Re: Sport 131/132 gearbox question.
Post by: simon131 on January 22, 2010, 02:42:53 PM
David,

You're just muddying the waters with that because the Sport engine is a type 131 B2.000 , it is not a 132 type despite 132 being cast into both the head and block. All very confusing.

Also, the final 2.000 doesn't necessarily mean that it's a 2 litre either as the engine type 131 C2.000 is a 1600 (1585cc) single overhead cam engine as used in the Series 3 CL, whereas the 131 C4.000 is the 2 litre Twin cam as used in the Series 3 Supermirafiori.

Also, just to totally blow the mind - if you're still interested at this point ;D - the Series 1 bodied 131 Brava in the USA was fitted with an 1800TC unit which had engine type 132.A1.040.5 or .6  ::)

That's it - lost you all now.

106 - if you can confirm the engine type from the block (stamped into it rather than cast into it), above the oil filter housing then it should give us a bit more to go on. 8)

i have an engine that has no numbers stamped above the oil filter its blank  there, it has however the engine number stamped just above the engine mount 132 C2000 ******* so its a 2000cc?


Title: Re: Sport 131/132 gearbox question.
Post by: simon131 on January 22, 2010, 04:55:14 PM
Should be, according to my information Nick :) or do you know it to be something different?

Engine type and number are usually stamped on the block just above the oil filter housing on a twin cam engine, but not always. You know Fiat - they'll stamp it anywhere, and sometimes not at all! ::)


Title: Re: Sport 131/132 gearbox question.
Post by: sid131 on January 22, 2010, 05:07:04 PM
 Simon have 3 more engines & just checked the numbers on them one is 132 c2000 & the numbers are stamped above the oil filter & above the engine mount & another engine is 131 b2000 stamped above the oil filter only cant get at the final engine as its well covered but i know its 131b 2000 so all 2 litre engines, the one on the engine stand has had a lot of tuning work done on it so should be fun.

Hello,

look here, pic for better orientation!

Enzo ;) 


Title: Re: Sport 131/132 gearbox question.
Post by: simon131 on January 22, 2010, 05:58:59 PM
Great pic for showing where the numbers are Enzo. Thanks. ;D

106's engine has a casting number that ends in a different number to the 131 Sport engine you have photographed so we'll have to see what type number he is able to get off his block 8)

Yes Nick, looks like all three of your engines are 2 litre - two Sport/Racing units and one from a 132. ;D

In my 2nd last post i quoted the engine block number i said i thought the last number or letter was a B but was not sure going by the picture it could be a 0
making it the same number as Fiat 131 abarths post and picture numbers
132 DB 2A 0.
I will post when i can the pictures.
Thanks,

Gents,

If the block definately has 132 DB then it is a Volumetrico.

There are several types with 132 D, for reference see the info here....

http://www.netikka.net/ville.vieri/tc/tclist.htm (http://www.netikka.net/ville.vieri/tc/tclist.htm)

Good also for the different locations of the individual unique engine number on the Twin cams  8)

Post by: jasonh131 on January 23, 2010, 01:20:28 PM
Anyway the gearboxes outside are generaly the same , with the gear lever coming out at an angle ,this removed and the two remote types sport and super are bolted in its place . :) :)

Post by: djape1977 on January 23, 2010, 10:50:37 PM
exactly, and it WILL WORK FINE  in your 131.
as for the gear ratios, as far as i know, there was only a diferent 5th gear ratio in diferent versions. some had 0.82/1 and some 0.78/1, so diference is small.
also, there's two diferent gearbox types on 131 and 132s, both having a cast marking on the side, one being 131AA and other 131AB. on the outside they look the same apart from diferent exit shaft. the part connecting the gearbox with rubber donut is sliding in one type, and bolted with a big nut on other. My 132 diesel had 131AA gearbox originally, and i swapped it for a 131AB when original one croaked after something like 400.000kms. if there was any diference in gear ratios i never noticed because i also swapped a rear axle at same time, instaling one from 132 1800gls, with shorter diff ratio and rear disc brakes.

Ok i  have the spare engine and box at last
On the block the following numbers- 132 DB 2 A C
Above the oil filter - Engine number 132 C 2. 000 Also 0758720
The gear box -FIAT 131 BB 1 A 1005 -- 44179965A
The carb set up on it is PIERBURG NEUSS. A German made carb.I think solex made them

Post by: simon131 on January 24, 2010, 02:44:38 PM
106,

Engine type is 132 C2.000 so you have a 1,995cc Twin Cam from a 132 ;D

0758720 is probably the unique, sequential engine number for that unit.

Seems to have a 131 gearbox fitted, but the BB doesn't fit the AA or AB refs from djape1977.


Title: Re: Sport 131/132 gearbox question.
Post by: djape1977 on January 24, 2010, 03:29:34 PM
i guess its still essentially the same gearbox. frankly, i have much more experience with 132s than with 131s. 131BB is probably found only in 131s since i never saw it in 132.
@106usj - post some pics of gearbox here so we can identify it more precisely. rear end of gearbox is rhe important bit since it may require different propshaft to fit to your car

Post by: 106usj on January 24, 2010, 04:17:10 PM
I dont want to drag this one out but i am just intrested in all the different TC engine's and all the different  gear boxes types there was etc.
I will post pictures on wed night some one has borowed my digital camera till then (Sorry.)
The gearbox number is for sure 131 BB 1A 1005.

To list all the different types of TC engine, as per Fiat's Engine Type on the vehicle data plate would take ages as the same fundamental engine was often given different 'type' designations depending upon the car it was fitted in, as can be seen above in the case of the 2 litre TC, for example -

131 C4.000   131 Series 3, 2000TC Supermirafiori
132 C2.000   132 2000
131 B2.000   131 Sport/Racing

All basically the same 1,995cc twin cam unit but used in different models.

The 1,600 units are even more difficult to list as the 1,600 was available as a 1,585cc, 1,592cc and 1,608cc unit and was given a 131, 132 and 125 'type' designation in each case, but for example the 1,585cc was used in the Fiat 131, 132 and Argenta models (RWD) as well as the Regata 100S and Strada 105TC (FWD), not to mention the various Lancia applications . :o

I could write a list but it would take ages and no-doubt someone would say I'd missed an application.

Gearboxes are another matter altogether and to be blunt, I haven't a clue where to start with those

From here you can find quite a good list of Fiat TC engines: http://www.netikka.net/ville.vieri/tc/tclist.htm (http://www.netikka.net/ville.vieri/tc/tclist.htm)
