Oil squirters are for cooling the bottom of the pistons and I haven't heard of anyone using or installing them on turbo buick motor builds . Sounds like your builder doesn't do a lot of turbo buick motors . This is from a thread back in May '11 , reply is from turbofabricator .The oil squirters sound really expensive, but this car did have a spun bearing that caused all this in the first place...
