your combo is screaming for a turbo around the size of a pte 54-
it flows a little more than the te44 and spools just as fast, good to see you have a 2800 stall convertor-
if its still laggy, then get a trans brake-
that 54 with 24 psi and a race chip and race gas your car would run really well-
you can take the stock turbo up to around 21-23 as everyone says, but if you get alky, or propane it really helps get rid of the heat the stock turbos create at that higher boost level-
HTH
EDIT- make sure you order the turbo, {where ever you end up getting it from}
with the pte exhaust housing-
ps- if you buy it new, you get a warranty
