Just wondered what the difference was in the P1 gearbox and the version 6 STi type-R box?,i know the type r has centre diff controll which i cant use on my P1 without an after market controller,but appart from that will i gain anything or lose anything ?,shorter/longer gears?,any help appreciated.

P1 has an STi gearbox but it also has the longer 5th gear

Shorter ratios, but not that much, I think - have a look at this chart The SPDA - Transmission Chart , but diffs and transfer gears are right, plus the dccd is fun - I've retrofitted one to my P1 with an original diff ecu, plus lights etc.

In my case I kept the P1 gear box and had the centre diff and transfer gears swapped. Pavlo at Zen Performance did it for me.

I think the STI Type R/RA MY99/00 do have the R180 reardiff, wich makes everything quite complicating!
