You certainly are correct, shoot I am surprised it is that well known even in the hot rod community, that's cool to know. And yeah it was produced in America up until 1996 which is the first year they introduced obd2... Which is another battle I am facing but I think I am gunna go the halted standalone ecu route... Anyway it was produced in Japan until 03 I believe and the jdm motors are much sought after. I have two blocks one from my non turbo motor and I have a twin turbo block as well. They are very similar except for a couple of oil squirters. Whichever is in better condition I would like to sleeve all six holes for a much larger bore. I've heard it can be done and read some posts and seem some videos in the mid 400s for horsepower and the response is silly and they rev out to 10-12k. Seems like it would be unique to do as well. "you may as well sleeve it and put in Q45 pistons from the VH45 in there. A .040 over VH piston is 94mm so that would put you somewhere around 3.5l. It's been done in a VG30E before." This is the original post on a different forum that got me thinking about it.
