VY CUSTOM.
You get better top speed on a manual, great accel with an auto :)

Its upto you really and want you want out of it, or if you prefer to drive manual or an auto.

im always after accel more than top speed, altho i would like to be able to acheive atleast 160-180 if i wanted to. but for me im all about accel, so unless i had the $$$ for a tiptronic i would probs stay with an auto.

I just wanted to know if the th700 used in the vn's etc would be a good option. if they are a stroner box compared to the th350 and if they would bolt up to the back of a 308 without an adation plate, new xmember etc.

im pretty sure the bellhousing patterns are the same i think the bolt up ok.... the turbo 700 has 4 gears aswell. but i think its got some electronics to figure out. not sure if its any stronger though

yeah, i believe the tailshaft is a different length, and remember it has a flange fitting to the pinion of the diff... as for the bolt pattern, it will fit if you got a turbo block, you'll prob need the VN starter motor and rear x-member tho...

but... on a 3rd note, the T700 is a lot weaker than the T350, ur only advantage will be the overdrive...

All turbo 700's have a 4th gear, the TH700 in the VN's up is equivilent to a
T180 used in the states, just with a 4th gear...
