yeah i know what u mean by make sure the guy tells me what he is doin before he does it. this guy owns his own machine shop called ryders in mechanicsburg, pa he has built many d16a1 he also has a 87 integra with the same motor and turbo and he is running 23lbs of boost in his and he drives it on the weekend (his daily driver is a 65 impala blown) he also did say that because he know that the d16a1 doesn't have a lot of power torgue that is why he is grindin and modifiy everything to fit so in essence he is makein his own engine. i do trust this guy he built my dads 355 sprint motor and that motor is still around with 150,000 of hard beatin miles on it . also my dad is talk to the guy who is doin this so my dad does know a lot more about what he is doin as in what crank rods pistons valves everything cuz the guy told him and he was tryin to remeber what he said after he got home. but he has all the stuff to machine it out and fit everything so. i also talk to a lot of the imports that sit in town and they all said that anybody that has he money to get tom (the machine guy) to do their motor, they are untouchable on the street. so i think imma go with this guy just cuz of his knowledge and his reputation.
