i have a 92 hatch that has a b20 block with b16 head that i recently bought from a friend due to it sitting in his garage for the last 8 years under a cover and i was needing some help. It has built internals with 10.0.1 pistons and i left it that way to see if i liked the way the car performed but upon me getting that car to run the sleeves were warped a little from it over heating years ago but i only installed new pistons and not sleeves. I left it with the 80 shot of now but my mechanic said that if i plan on turbo the car that i would have to re sleeve. I now like the way it feels turbo so i was looking to re-sleeve the motor but what I'm finding out is that most people don't re-sleeve the b20 so i am coming to you folks for a bit of advise on what to do? I was thinking of contacting darton but they don't work on those blocks? any help would be great on what bottom end or what direction to go?
