good turbo kits?
well you will need to build up your bottom end first
t3/t4 is a popular choice.

if i were you (but im not)
i would get a custom manifold made and use mitsu (DSM) turbos
like a 14b, that would do your car just nicely

the fact is that there are tons of these turbos available and they are decently cheaper than alot of the aftermarket kits you find online for the h23a1 and most honda engines

a friend of mine is running a 14b (stock 1g DSM turbine)
on a custom manifold in a 1986 CRX (w/ 89 integra motor)
BTW all of this cost him under $1000 INCLUDING THE CRX.

he is running in the mid to high 13's UNTUNED and at about 7-9 psi
