We can build VW & Porsche aircooled engines to your specifications and requirements, or even build your race engine!
All JS Auto tuning engines come with a dynamically balanced crankshaft, Piston rings checked and gapped accordingly,
Valve spring pressures checked and matched,
All bearing clearances checked and adjusted where necessary to manufacturers specifications,
best quality parts used,
and a 12-month warranty (on stock, mild performance only).
All our engine builds are run up and fully set up in house on our stuska water brake dyno, we are one of a few engine builders in europe that do this, usually engine builders perform cam burn and timing set up only, meaning you are required to take your vehicle to a rolling road for full tuning set up afterwards!
