I've got an IFS-R"-ish" car that was converted from a TA-05R with the old pulleys and front spool.
Question: Could I simply replace the (16 tooth) center pulley with an 18 tooth one and use with my existing 36 tooth pulleys to create a drive ratio of 2.0? If so, what belts would I use?
If not, and I have to get the 37 tooth outer pulleys too, would I just get the normal pulley to use with my spool? Thanks!
