I am about to install a turbo on my truck i believe its a borg warner s256 or s258 it has about a 58to 60mm compressor wheel and about a 70mm exhaust wheel with a ar of .80

any ideas on how thes will spool (fast, slow, high rpm, slow rpm) i got this from a buddy free so it is worth me trying out IMO
just wondering if anybody had any ideas how this will run.
i would have put it on last weekend but had to order 2 things to finish it and need a good full day or day and a half because i have to mount the turbo and build a down pipe.
Thanks for any ideas

 

it should spool fast theres not much clearance in that exhaust housing

 

i was thinking the same thing. It is an upgrade from the hx35 so to me it is defiantly worth trying

what is the specs on a hx35?

 

the 35 i belive is a 58 wheel aswell shouldnt spool up any slower than a stocker

 

could not really find any specs on a hx35, but did read on a fourm that it had a 56mm compressor wheel.
if some one finds specs on a hx35 post up a link or let me know

 

the 1 tons had 58mm wheels the 3/4 tons had 56mm
