Long time since I've posted on here! Have had an ARC engine for a number of years now, and with a fairly recent purchase of another breadvan it's time to do something with it. was planning on ITBs although driveability concerns are putting me off. Then with the recent finding that a 1.4tsi k03 turbo/manifold bolts straight to the 16v head (bar 1 bolt) I have decided to go down this route. Current planned purchases are: K03 turbo from a tsi AGU throttle body (yet to confirm it bolts to manifold) will port the head myself after my successes on both AAU and AAV engines. Speeduino management (pnp on AGU, same sensors on ARC) Either AGU loom or custom. Turbo plumbing (oil and air) intercooler wideband Injectors Fuel pump Parts I already have include: 1ltr flywheel Aftermarket clutch Various 084/5 boxes Slim starter Shortened oil pickup Short sump Complete front subframe from a 6n2 (engine, box, brakes, suspension etc) This leaves me with lowering the compression of the engine, seems that the stock ones melt on 7lbs of boost @180bhp. Ive been looking at various internals until I found a German company that build specialist head gaskets at various thicknesses to drop the comp down to between 10.5 to 8.1 depending on specs. My only concern is valve timing issues from the decomp gasket, and haven't found a vernier cam pulley yet. Also looked at various oem piston combinations but they all seem to raise the CR instead! Any advice welcome.!
