i have a turkish block with about one thousand miles on it,i know some people have had problems with them,but would you be happy useing it for around 450bhp?was thinking of getting 6 long studs put in,and also oil squirt jets,whats you thoughts?

 

its pot luck i'm afraid, some fail at 400 some fail at 600

if i was running more than 450, i'd rather have a turkish block long studded than a 205 block

 

out of interest what is a turkish block?

 

a copy of the 200 blocks made in turkey out of inferior materials - basically more prone to failure

 

ah right, thought it would of been something like that.

what normally fails on them? as if they are cheap enough would you not be able to line them with liners and long stud them?

 

they can fail at different places

liners dont stop them from failing, Dave (mad yum) had his lined and the liner moved and engine failed IIRC

although that was an extreame engine

 

ah right, thought being cheap materials the cylinders would of failed due to the pressure etc hence the liner question...

shame they are cheap materials as they would be worth weight in gold if they were decent... does anyone cast decent copies of the blocks?

 

How can you identify a turkish block? what numbers etc.

 

on the exhaust side of the block the numbers will begin or end (cant remember which) with 99

 

still quite a few 200 & 205 blocks about

Cosworth make an alloy block replacement, but have had no experience of them so cannot comment on strength, i believe mark shead at MAD was looking into them, there is a thread on here somewhere about them http://www.cosworth.com/shop_item.php?productid=470

 

Lots of new blocks that came direct from cosworth,were 99 blocks.bet there,s more about than you think,seen some big hp cars run them,until a few yrs ago,no body was aware of them

cheeRS stu

 

how can you identify a turkish block then? ( if i were to stumble on a 200 block)

 

on the exhaust side the numbers stamped will either begin or end (can remember which) with 99

 

got one in mine 5k miles at 2.2 bar t4 470 bhp and has been spot on touch wood.

 

Ah oke thanks,
and i believe i did read in an old fastford magazine Millington also has alu yb engines?

 

yeah i believe Martin @ Reyland has one in the Escort

 

Got a new block myself.Was told by the guy i got it from that its a belgium made block? the part number ends with 98.
