What is the best all round box I have got a classic sti short ratio box in the car not very good for motorways should i fit a long ratio box from a uk classic. Car is at 300 hp going to be on the rolling road soon want it doing before then

 

The sti box is stronger than the uk turbo box unless you want to go 6 speed i drove to germany from scotland my sti 5 speed dccd with no problem .

 

Best all round box possibly the 6 speed JDM
I'm running the v7 STI box in my classic,very short ratio and has the extra 6th gear so best of both worlds.
