picked engine up from dyno today making 260 bhp how can i beef up bullit box top take that power need to use 4 speed for hillclimbing

what mods to make 260bhp and at what revs? If you don't mind me asking how much ££££'s?

I guess you'll be giving £££ to Quaife or Tran-X then!!

quaife sequential should do you if you've got a spare £4000 kicking around?

what do caterham use in their 260bhp cars?

Caterham use the quaife sequential 6 speed in the R500 (260bhp car)

Plenty of 5 speed box options for the power, but not many 4 speed ones....

I think the quaife sequential is a bit more than 4k. Unfortunately because I want one. I too am looking at approximately 260-270bhp when my engine returns from the builder. I currently have a tran x straight cut heavy duty box so I'll let you know how it holds up at my first race.

unless you get your kicks out of re-building gearboxes with 260 bhp and the revs required to get to 260 bhp from a duratec the minimum i would go for would be a quaife 4 speed dog box
