STM Engine
STM currently offers a fully built 4G63 short block for the Evo 4-9. Lead times are around 4-6 weeks. We also offer the STM-Spec piston, various dipstick solutions and a machined billet aluminum oil cap for the Focus RS. The STM block-off plates come in handy for when the manifolds are off.
