So let's say I can get the std items rebuilt for around $1,200 and some good quality second hand -7 Garretts for $500 more, are they worth the extra? I guess the labour investment is high so need to make the right decision re parts. Once again I'm not going to boost the hell out of these things as its an older engine and for the street. The -7s are larger than std so I'm wondering if they might actually be a backward step (even though they're ball bearing) considering response and the relatively low boost.
Thoughts?
