if i got an engine number off a 205 block engine could some1 here tell me if its a thick or thin walled block?
ive been told that there were 2 different 205 blocks, a thin walled one that can take about 350 bhp and a thick walled one good for 500+
is this true?
and if it is and i put up the engine number could some1 here tell me what it is?

cheers

 

no need for engine numbers,, what size are the core plugs

 

pass

what sizes mean what?
lol
i will go and measure them but what sizes am i looking for?
cheers

 

i cant remember off the top of my head,, i just know the better block has smaller plugs

 

ok but i dunno what size the bigger ones are. lmao
i could measure them and still dunno what it means. lol

is there anywhere else that says about it?

 

any1?

 

you could look here on this site

http://www.siipicossu.com/manuaaleja/manuaalit.htm
if not here , i am sure this site will be of some use anyway for the manuals.

 

any1?

 

The std 205 blocks are coded YBB , the RS 500 Block is identical apart from the crank webs beefed up , the core plugs are smaller and weighs a lot more , thats coded YBD if that helps

 

where do i finds the ybb or ybo codes?
cheers

 

YBD not o , lol . the engine numbers are above the water pump on most engines , nicked ones are obvious from the angle grinder marks at this point !

 

the small core plug block is the rs 500 block .the core plug is about the size of 10 pence and as for the other 205 block its almost the size of a jaff cake

 

lol right off to check.

 

think its a std block
couldnt find the engine number or angle grinder marks. lol
i did see a large number atthe bottom of the exhaust manifold side that ends in BB
and the core plugs look larger than a 10p
