you got to build the internals (pistons rods etc...) if your going to run anything over 5psi. Do you have an AUTO or manual either way you got to get that rebuild (torqe converter) to handle the extra hp...

For cooling you'll need an a tranny cooler and i guess a big intercooler for your turbo which means you might need a new front bumper that would support your intercooler. You'll also might consider a turbo fan timer (you fan will run for 2-3 mins and cool your engine after you turn it off).

I believe ??accord98ex?? turbo his I4 and blew his motor after a few months, do a search.
