1g Throtle Body Questions ?

I hear how all these parts are completly compatable from 1 g and 2 g motors. Well this arouse a few questions. Im going to be rebuilding my 4g64 motor, And i would like to built it up slightly. And have a little boost going to it ( around 8 psi ) Nothin major. And i need to know Exactly what i need.. I mean, I have been searching on this subject for years and years. And well, i have hundreads of un orginized bookmarks, and lots of links. Any info on Where i can get a slightly built set of 4g63 7x bolth heads ( i belive ) for my 4g64 would be great.

Also a friend of mine had a throttle body for a 1g eclipse, That is failry nice sieze. 62 mm i belive. Mine is a 54 mm or something of the such, what ever Stock 4g64 's are. Any who, the 4g63 this came off of, was going the other way, so all the linkage's are diffrent. and blocked . Any info reguarding increasing this nifty thing that would increase the air comin into my engine, i would love you forever ;)
