hey guys I have a usdm gsr complete motor tranny and everything and im thinking about putting the gsr head on the b20 long block...just for the simple fact that I have seen no one in my area with this swap...would I be loosing power if i changed blocks? Is there an point in doing this or should I just throw the money into internals and build the gsr...I plan on goin all motor atleast for now...its goin into an eg hatch...

 

if you already have a b18c1 i would focus on building that. a b20 block has more displacement but that can be made up by sleeving and boring the b18c block, and at that point it will be way stronger than a stock b20 block.

have you ever thought about putting the b20 crank and rods into the b18c block? this would basically give you an lsvtec setup in a gsr block that already has a girdle and oil squirters.

 

nope never thought of that but it sounds like a good idea...might have to give that a try
