im pretty sure this question has been asked before, but i have no time to look for it.. or where to start, but, i have a base model 93' FD3S.. and im doing an engine swap, a 5.3L 323 w/ a turbo, and i was wondering how much hp/trq. the stock rear end can handle w/out snapping or doing any modifications to hold a lot of hp/trq... im estimating around 500-600hp not sure about torque.. probably 500-600 as well..

thanks.

pm me w/ info.. it would be quicker.. or easier for me to find.. =) thanks again.

 

Consider moving this to the general 3rd gen section. The diff isn't really part of the suspension.

If you do drag-style launches, the stock diff will break pretty quickly with that much torque. The axles (half-shafts) will break, too.

instead of telling me to move my thread, why dont u just give ur advice, and move on, wouldnt that be much simpler?? i dont have all day to sit here and look at this forum, and know exactly where to put things.. i dont use this site often..

thanks 4 the advice anyway.

 

well you would have scrolled over the proper section before viewing this one...
and yes, the stock diff. will go pop

 

Here you go *******:

Took me all of 30 seconds to find this post. Doubt you're that busy on a major holiday to not have 30 seconds of free time to look **** up.

Max is right about the differential not being part of the suspension, hence your thread is incorrectly titled *and* in the wrong forum.
