ls vtec turbo help
I am recently building a 1989 crx si ls vtec turbo. I have a b18a1 block, and pr3 vtec head, so far ive dropped all my money in the bottom end. Like getting it bored .5 over with forged pistons(wiseco) and rods(skunk 2 alpha), bearings(ACL extreme racing) and a moroso oil pan. When i rebuild the head should i keep it stock, or should i replace a couple parts. If yes what would you suggest i replace. Almost forgot to mention its not going to be a daily driver just a weekend car and planning to do anywhere from 8psi to 12psi or want at least. Thaks everyone in advance.

Re: ls vtec turbo help
You only really NEED to do valvesprings and titanium retainers on the head side. The rest of the components are fine provided they are in a good condition. If you building the block, you will probably want to run more than 12 psi ;-) On 93 Octane you can run a decent amount of boost and make up to 400whp depending on turbo and injector size whilst keeping stock sleeves and keep things reliable. There are guys that have pushed stock sleeves far beyond 400whp but the longevity of such setups is questionable and usually on borrowed time.
