our blocks are in no way shape or form, sleeved. we have iron blocks which are extremely durable. the only guys who sleeve them are the ones going for 800+whp.
as far as building the block, just use a stock crank, stock rods, and get some good aftermarket forged pistons. i really like the CP pistons i have in my 2.1L stroker.
don't worry about doing a stroker or anything. get head studs and a good head gasket (TTE, TRD, cometic, etc...). it would probably be wise to invest in a built head with cams and adjustable cam gears.
the next thing you'll want is a good sized turbo and a good tune job. make sure your fuel system can handle the extra airflow. probably at least a new rail, 850cc injectors, a good pressure regulator, and a high flow pump.
