1000hp(+) LS short block for Forced Induction applications 


Every engine is fully blueprinted and built by Stef himself – we are a highly dedicated race engine shop – not a production shop. Lots of time and man hours are put into each engine, that goes for 25hp VW engines to 3000hp LS engines – they all get the same treatment and every process of each build is photographed. Each build also comes with a fully detailed 2 page build sheet and surface finish report sheets with data collected via our Mitutoyo Profilometer.
