    Audi 90 S2 conversion - turbo advice please

    Hi there,
    I'm thinking about collecting bits to build my 90q s2 3b conversion and want about 400-450hp.

    I'm doing it on a budget and want some advice on turbos. I've seen the T70 turbos going cheap on ebay. I appreciate you pay for what you get, but if it breaks through abuse, I'll fix or replace.

    The T70 has/ is .68 A/R... whatever that means. Is this going to be to big for a 3b engine? sort of nothing nothing nothing then boost at 6500rpm

    I've been advised on the gt3071 but its big bucks and well you know?

    If you could let me know more on turbos etc, that be kool.

    Thanks

    James
