The BMW 4 cylinder m42 stroker refresh at shrigley engineering

The BMW m42 stroker went back to Shrigley engineering for a refresh as it has been in my rally car for 7 years and I have completed many rallies along with auto solos, rally demonstrations as well as driving up motorways to get to events. Andy has fitted some wilder cams, new pistons and new valve springs. When it came apart everything looked really good and hopefully it’s ready for another 7 years. Andy mainly works on Hillman engines getting great power out of them, he has worked on many vauxhall xe engines, rolls royce, aston martin and is currently restoring a Sierra Cosworth along with a rally imp and a space frame imp. check out his channel by searching Andy Jones hillman imp as there is lots of interesting things going on
