RE: Need quick Help on what engine to get For my trainer
A TT 42 GP would do it, as would an OS 46 LA, but a better choice would be one of the BB sport engines in the 40/46 class. -- LEO 46 Pro, TT 46 Pro, Mecoa 46 Tomcat, OS 46 AX etc. The 40 sizes are also good in the BB sport engines, particularly the TT 40 Pro, the Magnum XL 40, Super Tigre GS 40 & Enya 40 SS BB.
