Ford Pinto 205 block in a factory 1800cc Sierra?

hi

is that possible? a 205 block in a 1800cc car? and by the block numbers they are matching with chassis number and all papers?

the 205 block is only applyed to 2000cc engines, correct?

cheers

When Ford introduced the Sierra they also revised the Pinto production to resolve previous core shift issues amongst others. The new engines had new block codes.
135 for 1.3L 165 for 1.6L 185 for 1.8L and 205 for 2.0L All but the 1.3L share the same crankshaft throw but have different bore sizes so if you have a 205 block in a 1.8L then someone at some time has changed it and stamped the block with the matching numbers.





Never under estimate the ingenuity of an idiot!

it was a family car and I can't see the ownner made that change of numbers in the block. but my main concern is that without doubts the 205 block corresponds to a 2.0L engine.

1.8 engine had 185 cast into it.
If it says 205, itís 2.0L
I agree with the change engine number answer.
The only way to tell would be to pull the head off and measure the bore, however Ford could not afford to create a 1.8 block out of a 205 block as the castings are different i.e. they are cast with a larger bore

I don't know about that, but back when I drove an E-reg, Sierra 1.8 GL, it definitely had 2.0 (not 205) cast into the block. That was as it came from the factory. It is only a case of using smaller cores during the casting process and the cores will have been placed separately for such a casting.

All 205 and 185 blocks start out as cast at 1800 with a bore of 86mm. The castings are identical except for the numbers on the side. The 2.0 is then machined to 91mm.

Your 205 block is probably an 1800, just that the factory may have run out of 185 blocks so used a 205!

is that possible? a brand like Ford have such lack of quality control?

BTW: is that any way to check the engine displacement without disassemble the engine head? only through the spark plug holes?

so, if the castings are different, our friend Memphis said it is not like that.

man, I got confused. this valuable forum has been a great help for me for many years, but many times the opinions are very divergent.

I know, and in this case, only a person who worked in the factory can make a correct statment because it happened with him or with a factory colegue. out is this, could be someone read about the case or heard someone talk about that.

for me, the doubt persists.

anyway I appreciate very much the interest in answer to my question.

I am quoting Ike Flack, of IK Engineering. He knows more about Pinto engines than probably anyone in the UK.

And then Ford brought out the E-Max series engine. 1600, 1800, or 2000. It didnt matter because they ALL hhad the same outer block casting and crank shaft. ALL that Ford did was to vary the cylinder/piston bore size. This is why any Emax engine uses the SAME cambelt, a 2.0litre one. IF you REALLY need to sure, then, remove the head and measure the cylinder bore. My bet is, smaller pistons giving 1800cc.





Beware of the Goldfish in the tulip mines. The ONLY defence against them is smoking peanut butter sandwiches.

With Fordís history of engine quality, for example oversize main bearings on new blocks Itís more than possible!

hi all

only today I have access again to that 1.8 Sierra with 205 block, and manage to see the engine code in a way to solve the "mistery".

so is like this: my engine has a code NE (in that up rear right site where engine fasten with bellhausing) and according to my Haynes manual the 2.0 engines had codes NES and NET for carbs models. the 1.8 engines had codes REB and RED)

so, I did not see NES or NET but only NE. but for sure it is not REB or RED to be a 1.8 engine. so I am thinking this is a 2.0 engine, because those letters are not casting but engraved/punched.

tell me please your opinions.

thanks
Amadeu
