ok two questions :
as many would know im doing a full rebuild on my vl with a series 2 n/a block convert to turbo im aiming at about 500 bhp but am not sure what would be a good turbo to use?? also im in the process of getting a vl 5 litre diff for $880with a road tested 30 day waranty is this a good price?? are the 5 litre diffs stronger or weaker than the turbo diffs or the same?? i know it sounds dumb but if you never ask you never know

GT35/40

Diffs are the same, except the V8 diff ratio is 3.08 and the turbo diff is 3.45

cheers mate so should i get the diff ratio changed? or would it be ok? i know nothing about diff ratios still learnin also any idea how much a new gt 35/40 will cost?? and where i can get one from? ive heard that i shouldnt get one from auto barn as they charge an arm and a leg and also is the diff price of $880 ok or a wrought? cheers!

A new GT 35/40 should cost between 1800 - 2000.

If you want top end speed, stick with 3.08. If you want acceleration go 4.11

3.45 seems to be a good balance between the two.

You should be able to do better than $880 for the diff
