    Does it weaken the structural integrity of a LS 1.8 liter block to bore it out to 2.0, and sleeve it, with the intention of going LS VTEC turbo at 15-19 psi, with a Garrett T3/T4 turbo?
    All internals will be built, with an extrude honed b18c1 head and intake manifold.
    Would boring out the block be worth it, for more displacement, or should I just leave it at 1.8 and save some money?

    if you just bore it out to a 2.0 yes it will make it somewhat weaker, essentially a b20 blcok at that point. but if you have it sleeved to 2.0 then it will plenty strong. what kind of wheel horsepower are you looking for? psi numbers mean nothing.

    Looking for 500 whp. So sleeve the block to 2.0 and I'll be fine?

    yes, if its built and tuned correctly. research other peoples builds, see what they did to get to the 500whp area. thats what i would do. H-T has a shitload of detailed builds on it.

    You can also use a B20a (95mm) crank b16a rods with 82mm bore that will give you a 2.0 also.
