1kz power cvs

[Jaronimo]

hey all 1kz hilux fans
since building up my new 1kz engine in my 4runner to make over 150hp atw, ive since had to rebuild all my driveline, go figure 8in diff centres break easy,
so far I have broken the front and rear factory diff centres, im wondering if I should upgrade the cvs to the hd chome moly type or leave standard ones in?

150 hp should not be blowing up diffs.... I would guess that they were getting weak in their old age.

yeah thanks for the confirmation im needing,i believe it is just old age,
tho the 7.5in front diff is very small and I have heard a few poeple blow them with the 1kz when one wheel free wheels and comes down hard, but I havent ever really experienced that with the airlocker in the front very often, but tend to do alot of dunes/beach work
