If a 205 block was replaced with a NONE 205 would anything be different, i.e mountings, ancileries etc.
My original engine was a 1.6 Pinto which is apparently exactly the same mountings etc. as the 205 block.
I have since got a non-205 blocked 2L and it fits exactly the same as the old 1.6 did, gearbox, mounts etc.
HTH.

S I wonder what is the reason why you always see "205" block stated as if its some great advantage. I'm sure there must be something
uprated but would love to know what. Would it have less power, strength, weight???
Whats the magic.
Have a mate with a cracked 2.0 205 block and looking for another but could it be a none 205 2.0 and what would be the difference?
the 205 block I believe was used with the injection system and was modified slightly.
As stated mounting etc are identical but inlets ports etc are slightly different and allowed slightly better flow of gas/mixture.
Forgive me if the above is slightly inaccurate terminology I'm trying to remember from the pinto refurb book I used.
205 block is slightly stronger, has more metal around the cylinder bores to allow for over boring to 2.1 and makes them stronger, also a "selected" 205 block was used for the cosworth engines.
The 205 block is simply a later and somewhat stronger (and heavier) casting; the 2WD Cosworth YB engines were based on this block. Because of the
greater casting thickness they are the more suitable for boring out for larger pistons than the earlier blocks.
The 205 blocked engines in Sierras would have been injection engines as jabbahutt says, so they have a slightly better head and IIRC the conrods are a
bit stronger.
Pintos were also used in things like transits etc. I think they were not 205 blocks but were lower compression? I'm no pinto expert, so someone
correct me please
So if we are replacing a cracked 205 block with a non 205 and keeping the stage 2 head and mild cam that has been skimmed then there should be no difference to the old 205 block in performance?
My car had a non-injection 205 block. It was a German produced Sierra that it came out of. You should get the same performance from your block if you use the same ancillaries as were on the 205 but it may not survive as long if you treat it rough.
The 200 block was also used by Cosworth and I guess was resultingly a stronger casting. I did read an article recently by an engine tuning
specialist via a thread on this site that gave a lot of information on this question.

I concur with the previous,
..205 blocks have thicker walls and bigger webs...they are sought after becuse they are less lightly to twist, warp or crack under the hammering of
competition. They have a more 'meat' which means overboring with less risk.
Hi IanK, thanks for that reply. That Puma Racing thread was the item I had read!
^^ as all the above - if your not going to bore it out to a ~2.1 or sticking a turbo it then it won't affect you
(you can bore out a 20 block, just not as much as a 205 or 200)
its also worth mentioning that the stronger blocks are actually a bit heavier - so you might be slightly better off with the one you've got
the only other thing is the std. conrods found in the old carb'd engines arn't quite as strong as the later ones found in the 205 blocks
(early ones good for 6700rpm, late ones good for 6900rpm - according to des hammill's book)
we ran a non-205 blocked engine in a road rally car for a few years with no issues. Yep its not as "good" but it will do the trick.
Its only really a consideration if you are spending a lot on block machining, in which case it pays to have the best to start with
A few points to add but I do concure with most of what has been said.
Cosworth used specially selected 205 blocks untill the 200 was produced, the 205 block Cosworth produced 204bhp the best you can get out of a Pinto
SOHC non turbo (if you spend loads of cash) is 200 bhp, in reality anything over 160bhp is a good job if you have put it together on a budget.
The 205 block is safer to bore 93mm and can go to 94 if you are carefull, the reason for bigger bore is more torque and for fitting with a long stoke
crank (2.4 L).
The Transit block can be a 205 (I have one) and the later Transit 205 does not have a core plug at the flywheel face.
I have done a lot of research and spent a lot of money on Pinto's, if i was going to do it again i would save money on a rebore of a 205 block
and just fit Cosworth rods and Forged pistons to any 2.0L block. This would rev safely to 9000
All the power is in the head and the Injection head is much much better straight out of the box, again work is needed to get big bhp.

On a 205 block look behind the dizzy you will see 4 numbers 1111 or 2222 or 3333
The 1111 are always cosworth blocks
2222 are the next best blocks and so on

The 205 block is as has been said above stronger. having said that using a 2.0 block for your rebuild will be of no notable difference. As for transits, they did have 205 blocks but were fitted with low compression pistons. They also came later with 207 blocks. 205 blocks only have better heads if the were fitted with injection where they flow better, the can be identified due tio the different inlet port shape, however, if you are porting a head the injection and non injection heads are both suitable, it's only when they are fitted as standard that the injection one makes a difference.
