Designed from scratch is the upgrade kit to convert the Kaase Boss9 design in my store to the Roots Supercharged version.Both the ITB design and Roots design complete engines are available in my store, but if you only want the upgrade kit for the NA without buying a complete other engine, this is the Supercharger items only. High in detail, ideal for scale modeling (currently in 1/24 and 1/25 scale).

Perfect for those drag racing builds!

Kit includes the integrated 10/71 Roots supercharger and intake manifold with burst plate, offset MSD 2 piece distributor, twin throttle bodies or a blower hat option.

Be sure to tag @mattys_custom_scale on Instagram with your finished prints & projects!
