205 block
robertst - 13/7/07 at 11:24 PM

got most fo the crud off the engine today and when i noticed those three letters stamped on the block (205) i immediately screamed "YEAHHH ITS A 205!". but soon enough i wondered why i had celebrated the fact i had a 205 block if i didnt know why it was good...

so apart from being able to be rebored to 2.1 or 2.2 litres, what is the advantage of having a 205 block?

Non.

The best cossie block was the 200, which was strengthened in places, the 205 block was used by the earlier cosworth engines as well as many other Pintos, including the Transit and Sierra, so the 205 isn't exactly a rare thing.

Stronger block so less flexing if you have big power. The bore walls are thicker thus you can bore to 93mm and even 94mm.
In reality 5% increase in capacity is not much but with V6 pistons and cosworth rods you can go to 8000rpm cheaply.

but cossie rods bring there own problems - trust me

if you went down this route you might as well stick with the later pinto rods (as found in most 205 blocks) and not rev it quite as hard, that way it will be alot cheeper

Will also be a safer bet when blowing it, should you go down that route.
