wel considering i went from a 36cm to a 23cm its night and day difference, i bought the garret ht3b brand new for a good price, neve new to much about housings then. figured it the reason why it didnt sound good and never made much boost and kinda slowed me down was a 36cm housing!! had a guy and the local diesel shop for a 23cm. found one in 2 days completely redone for 150$ i never ran one with a 26 before, but i started alot of threads and asked alot of opinions, and everyone pointed to the 23 for a dd. the spool up is amazing,(ht3bs spooling up almost faster than my superhx40 that has a 16cm housing). gotta keep the foot out of it untill the orings come
