Hand assembled by us here at The Skyline Shed is this 'top of the line' PPG 5-Speed GTR Gearbox. This transmission suits those who are making or planning to make over 1000hp and want to drive their car to and from the track with peace of mind. This unit also has a standard 5th gear synchro setup for those smooth quiet rides on the freeway (5th gear is not a weak spot in these units). Many upgrades have been performed overall to this unit, right down to the transfer case which is fully rebuilt with new OEM Nissan parts, along with additional friction plates for better distribution of power. The entire gearbox casing and transfer case housing has been vapour blasted for that nice OEM cast alloy look and a Speedtek lockout shifter has been fitted to prevent you from selecting incorrect gears and causing any damage, this shifter has been used on the worlds fastest H-Pattern GTR which ran a 8.04 @177mph.

Transmission has been fully sealed and taped off, ready for local pickup or worldwide shipping. For a shipping quote, simply add this item to your cart and then continue to checkout for accurate shipping rates.
