For those that don't know and for people like me trying to find sources of info.
I have found this mega site that talks all about the 7A-FE engine (albeit AE102 Corolla) including turboing it - yer way to go!
Check out the modifications section of this site: http://www.corollaperformance.com/ especially http://www.corollaperformance.com/Mods/Engine/7AGE.html#rayhall

the G-head conversion is not cost effective. your better off doing a straight up turbo of your existing 7AFE and run it at 8 psi or less, or for higher boost levels reinforce the internals with 4AGZE parts, etc. I don't know exactly what needs to be done as far as internal reinforcements, but you should be okay up to 180 hp or ~ 8 psi.
