Engine Block Modifications :))

As Promised guys... here are some pics showing the changes made to the engine liners which have been replaced with special iron ones and the pistons upgraded...
We opted to make the liners thicker to withstand prolonged use and used higher spec continous piston rings and ligher pistons.
The pictures speak for themself .. you can see the increased thickness of the new liner compared to the old one and we decided to engineer and over lap between cylinders to make sure the liners are supporting each other which strengthens the engine structure...
The picture are before skimming the block or honning the cyliners so never mind the levels they will be all be spot on when it is finished.
The key thing we had to do is to rebuild it to BMW manufacturing spec as far as measurements is concerned and we achieved that spot on as well... All spec from BMW TIS system.
The Head is not receiving much focus as theere was nothing wrong with it anyways but it has been fully cleaned and rebuilt.. will post some more pics of it...
Expect it to be running in 2 weeks time :-))
