I own a shop with everything laying around to do plus three f23 blocks but i see no need . The only gain is steal sleeves which if you bore them big enough to run a h22 piston there to thin hold boost . people dont realize how cheap dry sleeves are and if your not going to make over 400hp just run the mahle pistons no need to sleeve the frm block. Alot of people dont realize that the closed deck frm sleeves are very good most high end cars run them . They actually run cooler and have less wear then steal sleeves. The only draw back is forged pistons want work but since they came out with the mahle pistons thats not a problem any more . Personaly i would find a f20b block before i wasted my time on a g23 (which i have one of them also lol. It has steal sleeves , runs a 55mm crank so a f23 crank will bolt right in, and a h22 head bolts right on no modifications . there are so many options out there i just dont see why anyone would go through the trouble to build a g23 . people say well i had the parts laying around. Well guess what it cost the same money to build a h22.gsr,b16,h23vtec as it does to build to crap you got laying around and id rather put my money in a nice set up .



i guess we are gonna see what they can hold then ayye??lol
