Sleeve your block, and replace all internals with forged parts, then you'll be good to go.

Okay Im sorry this might be a retarded question, but when you say replace with forged parts do you mean like the pistons and camshaft and stuff like that. Are those the forged parts you speak of?

Use the search function, and search for FRM sleeves or h22/h23 sleeves
basically, stock h-series engines don't hold up well to turbo applications. Especially ones with 140K....
Get your learn on for a few months, then go for it.

140k is a ton of miles to throw a turbo on. A Compression test and cylinder leak-down test will definetely need to be done before you think about throwing a turbo on that stock motor.

Your car has a lot of miles, so if you want a reliable turbo car, you'll need to rebuild the bottom end of your motor. Your stock sleeves won't be able to consistently handle the power of a turbo application, so you will need to "resleeve" your block's cylinders with a stronger material. And since you have the block open, you might has well replace the other internals with stronger forged parts, like pistons, etc...
The whole thing will probably cost you around $2k, but it's well worth it because you'll car will be able to handle a lot of power reliably.

They're not, but they weren't made for turbo. The stock FRM sleeves will handle 8-10psi fine, but the question is how long? The life of the engine will go down considerably.

Re: 93 Si h23 turbo help (dtec)
not because of the sleeves. It's the rings that will go out way before the sleeves do. Especially the open deck blocks with all the extra cooling they have being surrounded by coolant.
i have yet to see someone crack a stock FRM sleeve. And if it has been done i would like to know the power levels which was reached.

Re: 93 Si h23 turbo help (98vtec)
correct. FRM is much stronger than people give it credit for. the piston ring lands are the weak points. but due to the frm you cant just slap any old piston in there. OP search around and do alot of reading you will be all the better for it.
