Blox Racing LS/VTEC Conversion Kit
Without a doubt, LS/VTEC conversions - commonly referred to as Frankenstein B-series motors – are one of the most popular engine builds and modifications performed to date… and BLOX Racing makes it simple to do. BLOX Racing offers engine builders a complete kit that transforms a non-VTEC Honda B-series engine into its high revving DOHC VTEC counterpart with no machining requirements.  Different head gaskets sizes are available.




Darton Sleeve Kit
Mitsubishi 4B11

Darton introduces a new patented M.I.D. Sleeve Kit for the Mitsubishi 4B11. You can now convert the block to a closed deck utilizing the M.I.D. wet sleeve. This allows you to take the stock bore size out to a much larger bore size and still easily handle over 50 pounds of boost at any compression. Since the kit is a wet sleeve design, you can change individual sleeves or all 5 without needing to re-machine the block. Darton also offers installation of the kit with a 15 day turn around.

HKS pistons also feature nickel-plated piston heads and specially-treated piston skirts to improve anti-knocking performance and reduced friction.
