im currently runnin a greddy sohc kit on my zc. tdo4 15g turbo on it. it runs well but that turbo has some shaft play. not hitting the housing or nothing yet but some is there so i dunno if i should run thAT turbo till it breaks which could be a while or not i dunno . or if i should swap on a 300zx garrett t25 that i have layin around.. the garrett looks a lil smaller but i dunno for sure? im only runnin 8 psi now but in spring ill be uppin it to about 16 or so .. will either turbo have a problem doin that? i dont think they should but i need 1st hand experience.. which is better the t25 or 15g?

 

yeah a 15g is much better than a T-25...
