From all the info I have learned off this site I see no point in buying a b20b block. It has all the same internal specs as a b18b but with a wider 84mm sleeve. Is that all you have to do to make your b18b block a 2.0L ?What are the big benefits to boring out your sleeve to 84mm? Also, My last car was a turbo eclipse and for those of you who have driven a turbo car its a whole lot of fun. I don't want to be without a turbo motor its like crack to me now. I cant seem to decide if I should build up a b18c block with 10.4:1 high compression pistons or 8.5:1 low compression pistons. All i want is 5-6 psi with a 14B turbo. I plan on building the complete block and getting forge rods and forge pistons. Should I drop the compression with that low of a boost? My plans are just to be over 200hp, and have boost bring up the torque to nearly as high as the horsepower.
