Not sure what power its running as it hasnt been fully tuned yet. Has all the right bits but its only on a T38 turbo so def cant be anymore than 500 id say...
Well i think R+D diffs are out of the question at the moment..£3500 for a front one on ebay!
The rear diff has broken the planet gears so a gripper or quaife unit would prob solve that. Problem is how much torque can the crown and pinion take.

thats all well and fine saying a 9" diff will be worth more in a few years, my problem is that i never sell anything..I either keep it for ever or break it
