Best engine...

Let me use the term that Honda calls it.... Fiber Reinforced Metal (FRM)Cylinder wall lining. It's really good for for all motor, but a complete disaster for boost. Not to mention that it's an open deck design. And even though you can buy the cylinder brace thing that keeps the sleeves from moving (help me with the name, please!) What's the point of doing all of that? Get a motor that already has a closed deck that is more than capable of holding boost without buying any extra parts. As far as the rev limit.... meh, who cares? 7200 rpm should more than be sufficient for boost. You don't have to rev the bejeebus out of it to make any power. Nice sized turbo + good set of cams and pistons = win.

Actually the FRM sleeves are very strong, and they only come in the 5th gen prelude h22's. An h22 from a 96 and older were iron sleeve closed deck blocks, so I would say they are pretty strong. The weakest point in a FRM h22 is the pistons, just like any other honda. Very few companies make a FRM compatible piston and I dont really know that I would trust them. Hondas first attempt at the FRM sleeves were in the b21a1. After 300k miles you can still see the cross hatch from the factory hone, they are pretty hard on rings and few machine shops will attempt to hone them.
Just boost the stock engine, talk to emmino on here.

the frm sleaves cam in the 92-96 h22 the 5th gen h22 and the 4th gen h22 are identical other than the closed deck and the H23 has frm sleeves... and for the pistons answer they are called MAHLE pistons porche runs frm sleeves and they run MAHLE pistons stock and they have some for an h22
