I have a b18b1 out of a 1994 Integra Ls. I am rebuilding the motor and in the future I plan to run about 15 lbs of boost. Wich rebuild is more inviting to psi. By the way its going into my 5th gen civic

 

If built right both setups will run well.

However the LS/V will cost more money. Personally, I'll take the extra money from the LS/V and put it toward other items in your build/project.

What's your power goal? PSI is irrelevant...once you tell us that AND the fuel you plan to use, we can accurately answer your question.

 

I really want to get 250+ hp with the turbo. I just want to run pump gas. supreme probably. that is what I run anyway.

 

Either engine will do that with relative ease. I can tell you from experience that GSRs love boost and will handle quite a bit more than what you're looking for on the stock block. The numbers in my sig are on the stock GSR block...the FS link has my dyno graph if you want to see just how streetable it can be.
