I got my car like 2 weeks ago, Got it with 135,000 miles, Its a DOHC VTEC prelude. I wanna turbo it, but im somewhat scared bout the mileage. So, I was thinking bout rebuilding it, I started making a list and checking it twice bout the stuff I wanted to do when I rebuilt it. Problem was it was coming out a bit too expensive. So, I was thinking bout only rebuilding the bottom end only then turbo'ing, then work on the head. So, my question is with crower rod, JE low compression pistons, Knife edged crank(maybe, still thinking bout it) and re-sleeving the block, would it be safe to run about 5-6lbs of boost? Also, when I do rebuild the head up, What kinda cams and valve train should I use I ws thinking about using type S cams and type S valve train, would that be wise? Also, what kinda valves should I use? One more question, when I re-sleeve the block, Do I have to take it out of the car? or can I just tow the car to where Im gonna have it done? How much would re-sleeving cost me? And, a block guard? whats the purpose of one? Can I install it with just removal of the head?

You can run far more the 5-6lbs of boost on a built bottom end, even if you don't touch the head. For Valves, you want stainless steel ones, Crower and Ferrera both offer them. They take abuse far better than stock valves. You don't want Type-S stuff, it's made for NA power, lots of overlap. If you really want to go for cams, try out the Crower turbo regrinds.

When you get the bottom end done the procedure (if you don't take the engine out yourself) is to take it to a shop that will take the engine out and ship it to the machine shop for you. Machine shops that do engine build ups usually stay far away from services like pulling engines.

the rebuild will realistically cost you $3500+ depending on the machine shop.
je pistons go for $500-$550 and the crower rods for $650-$700. don't forget about resleeving. resleeving can cost from $500-$1500 depending on the shop. but most common machine shops will be closer to $500. you'll also need all new bearings as well as getting a new water pump, oil pump and such.
overall it's an expensive project.
