actually 94 teggy is when they went obd-1 and the motor got a 10hp increase. my brother is putting a us specb18b1(from a 94) in his DA, he had a valve job done, head milled, it should run pretty good. i may be able to get you a machined LS head for like $200 and if the valves were done right it would be good. also a b20 with the right tranny is good, i have a buddy with a DA and he had a b20 with an LS tranny and alot of headwork and he ran with me before i got my cams until my tranny took over, i was impressed myself.
