I was thinking about putting together a budget turbo kit for my wagon over the next couple of months using an EXP manifold (just lost one on ebay), RHB5 VJ 11 turbo (why? because I have one in mint cond.), and all of the usual other stuff. I thought to myself getting another SPI long block would be a good idea, do a fresh rebuild on that and when the car has a good tune and I'm happy with the way it runs throw the fresh motor in it and turn the wick up. Anyway my main question is are the SPI blocks Sleeved or not? wondering because this way I could get away with a honing and some rings and bearing in the extra block.
