With me running the rb25 in my 325 touring with standard diff, drive shafts hubs etc, i'd just like some info on what i could do to the running gear so i dont start breaking things over 300bhp. eg. Is there i certain diff that would take 300/400bhp? uprated drive shafts etc.

The driveshafts and diff will handle the power, but the standard diff mounting point has been know to be ripped from the body with big power.....

there is a picture somewhere.....

I would IM DanTheMan I remember him posting up that he destroyed a drive shaft at the pod this year and he is running an alpina lump so will be close to the 300HP mark.

Dans' Alpina is running 267bhp.
The reason Dan broke the dfrives shaft was down to the Pos track getting rubber down and causing more grip in the lane that Dan was in.
There were 2 other cars with the same problem in the same lane.
