V-max Rb25det

[T-u-R-b-O]

Hi guys,

I have finally complete my RB25DET swap and got it tuned to 0.7bar ... i have swapped the complete RB25DET inkl. gearbox, and full rear end (incl. the stock RB25 diff) ... last friday i took the car to the highway, and measured with GPS a top speed on only 248 km/h @ 6850 RPM...

how can i make it go more (except upping the RPM) ? is that possible? maybe changing the transmission for 5th gear only to make it longer? or different diff?

what expenditures?

thx,

Nico

Change the diff for a longer ratio. Although I might warn you this thread will turn messy for obvious reasons. I hope this highway was private lol.

dont we all have our own "private" highways ...

what diff you suggest? i remember hearing something that auto diff tend to be longer?

thx,

Nico

You said it yourself in your first post.

Thread locked.

Dont talk about street racing "private" testing or whatever. Dont want it here.

Cheers
